On the geological characteristics of non-ferrous metal ore formation and prospect of finding ore

  Non-ferrous metals are non-renewable resources, so it is necessary to use advanced technical methods in exploration and mining, take effective measures, adhere to scientific and reasonable principles, effectively improve the opening rate of minerals, and fundamentally adapt to the needs of economic and social development.

At this stage, the search for new deposits has become an important task, on the one hand, because of the limited number of easily identifiable deposits on the exposed surface and in the shallow part of the earth, and the difficulty of investigating deposits in the deep part of the earth; secondly, the lack of advanced mineralization model theory, mineralization prediction theory and effective mineral search methods for guidance.

  The metallogenic model reflects the understanding of the law of mineral deposits and is a simple overview of the geological, tectonic, geochemical, geophysical and other basic characteristics of the same type of deposits. Mineralization prediction, on the other hand, is the process of quantitative evaluation of mineral deposits with the mineralization model as a premise. It further speculates on new mineral pathways by taking into account the geological environment of mineralization, mineralization conditions, mineralization theory, mineralization signatures and the influence of mineral control factors on potential deposits.

Therefore, we can use advanced scientific methods and geophysical theories as the basis to establish the corresponding metallogenic model guidance in the actual mineral search work, which can fundamentally alleviate the blindness of mineral search work and effectively improve the efficiency of mineral search. It has been proved that the research and prediction of mineralization model can not only make the research of mineralization theory, deposit genesis and the classification law of deposits more systematic and theoretical, but also promote the search for hidden mineral resources in the deep part of the earth to a certain extent.

Since the geological situation of each region is different, the author here mainly takes the non-ferrous metal ore in a certain region as an example, and discusses the metallogenic characteristics and the distribution of ore areas in the region by combining the experience of mineral search in other regions and the characteristics of geological environment.

  The concept of nonferrous metals

  Non-ferrous metals in a broad sense involves a wide range, which not only includes precious metal minerals such as gold, silver and platinum group, rare earth metal minerals, rare metal minerals and dispersed metal minerals and other metal minerals, but also includes light metal minerals such as aluminum and magnesium, heavy metal minerals such as copper, lead, zinc, nickel, cobalt, tungsten, tin, bismuth, molybdenum, antimony and mercury, etc. It can be said that as long as the ferrous metal minerals are removed, all other mineral resources belong to Non-ferrous metals.

  Brief introduction of metallogenic model

  Ore-forming model is a high generalization of the ore-forming action in the four-dimensional space, which is finally expressed in different depths, forms and contents, and is gradually deepened with the development of theoretical research on ore deposits. Regional metallogenic model, deposit metallogenic model and ore finding model are three common metallogenic models, which are developed on the basis of the summary of previous research on metallogenic models.

There are certain differences among them but they are distinct from each other. First of all, as far as the regional metallogenic model is concerned, it reflects the metallogenic law of a certain metallogenic area or zone, and is a summary of the characteristics and metallogenic law of various solid minerals in a specific geological unit; the mine field model is not only the expression form of the metallogenic law, but also a model describing the formation process of mineral deposits; while the mineral search model reflects the basic characteristics of minerals and the basic composition of minerals to be

In practice, regional metallogenic model and deposit metallogenic model provide the geological theoretical basis for deposit exploration, while the mineral search model can guide the mineral exploration work, and only the combination of the three can better serve the mineral search work.

  Analysis of the geological environment of non-ferrous metal mineralization

  The northern part of a region is located in the southeast coastal foreland thrusting and faulting zone of the Eurasian continental plate since the Mesozoic, and has the status of compound superposition with the Yangzi and Huaxia ancient plate combination zone, because the geological environment in which it is located has superiority and special features, thus forming a unique environment for mineralization.

  (I) Crust-mantle tectonic characteristics

  Since the Mesozoic era, the main geological structure of non-ferrous metal mineralization is crust-mantle structure, through the comprehensive analysis of heavy, magnetic, artificial seismic profile and geodetic electromagnetic sounding and other data, we understand that the crust and mantle of the region has the following characteristics.

(1) The existence of multi-layer detachment zone in the crust.
(2) It is characterized by thin crust and thick upper mantle, with the highest gravity field (+15 mgl) in the area of Boyang, which is the thinnest area of crust in South China.
(3) Its northeastern fracture has significant misconnection to the Moho surface.
(4) The northwestern part is a gravity low anomaly zone, and the gravity high anomaly axis occurs in the north-northeast direction intertwined with the north-east direction.
(5) In general, the thickness of the crust and upper mantle shows a trend of gradual thinning from west to east, and the central part is the axial north-northeast mantle ridge area. The existence of the above features is inseparable from the Mesozoic large-scale rock-forming mineralization.

  (2) The paleotectonic pattern before Mesozoic in some areas

  After the study of related data, it is found that Huaxia and Yangzi are the paleotectonic patterns before Mesozoic in some areas. Serpentine greenstone has been found not only in Fuchuan, Shexian County, Anhui Province, but also in Dexing and Yujiang, in Liuyang, Hunan Province, and Longyou, Zhejiang Province, where mixed serpentine green tectonics or serpentine greenstone fragments have been found.

  (C) Geological and tectonic features of the Mesozoic

  In the Mesozoic, there are strong deep and large fracture zone activities, widely developed two major pushover tectonic systems, significant large-scale slip shear and extension, so it has caused many twisted zones and great fracture layers. Especially, the north-east-north-north-east direction, and the east-west and north-west direction of the three major composite terrain is formed due to the frequent occurrence of fracture mountain building and plate fracture movement.

  Nonferrous metal mineralization characteristics

  Taking the metallogenic characteristics of non-ferrous metals in the northern part of a region as an example, the deposits show different characteristics in terms of metallogenic time, deposit distribution and deposit formation, etc. The best description of the metallogenic time of non-ferrous metal deposits is “multi-phase mineralization and the strongest Yanshan phase”.

In terms of distribution, non-ferrous metal deposits mostly show “block” and “belt” mineralization zoning with deep fracture zone clustering at the edge of the block and “oceanic” zoning along the foreland thrusting and faulting zone; in terms of formation, non-ferrous metal deposits show “block” and “belt” mineralization. The formation of non-ferrous metal deposits is characterized by “multiple mineralization superposition and multi-type aggregation”, and the complex rock control and mineralization control by slip-torsion and push-slip overburden tectonics, which are carried out in a multi-layered manner in both plutonization and in-situ mineralization and mineralization, and the coupling relationship between the controlling factors and distribution environment in large mineralization areas.

  The Middle Neogene, Hesperian, Indo-Chinese and Yanshan large-scale mineralization periods are the main mineralization periods, all of which have different characteristics. In terms of the Miocene metallogenic period, it has a certain amount of ancient volcanic rocks, which not only exist in the form of combined late Miocene and Qingbaikou Period volcanic ditch arc-type rocks, but also have a close relationship with copper and gold ore; in the Haixi metallogenic period, there is a part of local mineralization of non-ferrous metals, and even the formed ore layer has industrial significance.

The typical metallogenic feature of the Indo-Chinese metallogenic period is metamorphic hydrothermal mineralization, which includes magmatic hydrothermal related gold and tin ores as well as metamorphic hydrothermal mineralization, mainly formed by gravity; Yanshan metallogenic period, the time of mineralization is about 180-100 Ma between the late Jurassic and early Cretaceous period, influenced by several volcanic movements and magma intrusion position formed large-scale non-ferrous metal deposits.

  Prospects for non-ferrous metals

  The remarkable mineralization effect in the northern part of the region is mainly due to its frequent volcanic activity, which, together with the Mesozoic and Cenozoic orogenic movements, accelerated the frequency of tectonic magma superposition. In-depth exploration of the formation conditions of gold, copper and other non-ferrous metals reveals that they mainly benefit from the frequent activities of magma, which provides mineral and heat source water for the formation of these non-ferrous metals.

Then by analogy, we can roughly predict the distribution and mineralization types of non-ferrous minerals in the control mineral belt: ductile shear zone type gold, tectonic alteration rock type gold, porphyry and xenolith type copper-gold ore and marine jet sedimentary stratified control type copper ore, all of these mineral resources show a better development prospect. Therefore, in order to fundamentally alleviate the shortage of non-ferrous metal mineral resources, it is necessary to accelerate the exploration of the peripheral geology and the deep part of large mineral production areas.

Analysis of crushed concrete construction technology in water conservancy and hydropower construction

  The concrete construction of water conservancy projects has been one of the key points of water conservancy construction, because the concrete is for the overall body to play a supporting role, the main building materials of China’s water conservancy projects are steel and concrete, but usually the characteristics of concrete in the water is not good, can not meet the requirements of the technology, which requires the addition of crushing technology in the construction of concrete to enhance the quality of concrete.

  1 Project Overview

  The main function of a water conservancy and hydropower project is to generate electricity, the total capacity of the reservoir is 26.51 million m3, the total length of the river is 50km, the rain-collection area is 320km2, and the width of the dam roof is 5.5m. The project is mainly composed of the diversion tunnel, the crushed concrete gravity dam, the power transmission tunnel, the power house, the booster station and other buildings, and the annual power generation capacity of the project is 2988.6kW per hour.

The material of the crushed concrete gravity dam is mainly divided into five zones: the upstream surface is made of secondary with crushed metamorphic concrete (1m thick C9020), the inside of the dam is made of tertiary with crushed normal concrete (C9010), the downstream water level change zone is made of secondary with crushed metamorphic concrete (1m thick C9020), the dam foundation is made of tertiary with normal concrete (1.5m thick C9015), the top of the dam and other casting zones are made of tertiary with normal concrete (C9030). The total amount of concrete for the dam body is 106,000 m3.

  2 Concrete crushing construction plan

  In the concrete construction program to be based on the construction of the weather conditions, temperature, air humidity, etc. to do a good job of monitoring and evaluation of merit, in the construction of concrete is in accordance with different conditions to choose a different construction program, according to the construction program can also choose a different concrete ratio to improve the quality of concrete.

Before the construction according to the characteristics of the concrete, should choose a reasonable way. According to the construction requirements of the dam to complete the concrete pouring work. Therefore this requires the concrete construction to first investigate the site of construction first.

  3 Construction technology of compacted concrete

  3.1 Mixing concrete construction method

  Mixing concrete construction method is the concrete construction is, now the raw materials of concrete together into the mixer, and then the mixer for mixing, through the mixing and crushing technology, the raw materials will be evenly distributed, because of this way the concrete solidification time is later, so the tightness of the concrete but often in the concrete for pouring because of the mixing tank and pouring the zone of high distance, the concrete appears segregation This seriously affects the quality of concrete, so the general requirement of the vertical drop of concrete does not exceed 1.5m is better.

In order to ensure the quality of the dam, it is necessary to have strict control measures on the discharge of the mixing vehicle, the location of the pouring, and the concrete segregation test data. Therefore, this causes the construction is more complex, bad management and other phenomena.

  3.2 Laying crushed construction concrete technology

  Because the main body of the dam is in the water, it is necessary to ensure the compactness of the concrete construction, the management of concrete quality after the concrete construction is very important.

In many cases, if there are certain gaps between the various layers of concrete construction, on land such gaps may not affect much, but in the water, water will gradually immerse in these gaps, through the flow of water and pressure, resulting in gaps continue to increase, eventually leading to the phenomenon of inter-layer shedding, bringing great harm to the safety of the dam.

So the concrete construction in the dam to do two issues, one is to prevent the bond layer gaps, the other for the prevention of water infiltration. This requires some good techniques to complete the construction of the concrete body. To improve the quality between the bonding layer, its main method includes the construction of a new concrete layer quickly when the concrete is first set, which can make the concrete bonding tight and prevent the formation of cracks at the same time.

When the area of construction is too large, the method of pouring with the aid of steps or laying flat is used. Such a construction method is also susceptible to the construction site, if the construction site is small, it is necessary to use other techniques, usually according to the shape of the dam and then use the construction method of inclined layer pushing paving. This construction method not only conforms to the unique shape of the dam, but also solves the problem of water accumulation by constructing from the bottom up.

But to meet the technical requirements requires good rolling technology, to ensure that the concrete and the bottom layer of a tight connection without air bubbles, water, gaps, etc.. Therefore, the aspects to be controlled include the strength of rolling, the thickness of rolling, the frequency of rolling, etc. In the location of the overflow of the dam because of the high water level, so the highest standard of concrete construction is required.

  3.3 Control the temperature of crushed concrete

  During the construction of crushed concrete, cracks often appear on the concrete due to improper arrangement of concrete temperature control measures and unfavorable operation. If the temperature of concrete is not controlled in the specified range, cracks will easily appear in the process of rising concrete temperature, resulting in a reduction of the impermeability and quality of concrete.

In order to improve the quality of crushed concrete construction, the temperature control measures for mass concrete should be done during construction. In this project, two main methods are used to control the temperature by increasing the heat dissipation rate of concrete and reducing the heat generation of concrete.

Most of the concrete used in this project is proportioned by three-stage proportioning, and the particle diameter of concrete aggregate is 45-85 mm. in the process of construction, in order to effectively reduce the temperature of the concrete into the warehouse and prevent the appearance of cracks, the construction is not carried out during the time when the temperature is too high at noon.

  3.4 Construction technology of rolling and paving mixes

  In order to make the concrete paving quality to be effectively guaranteed, paving operations generally use asphalt pavers for construction, in order to ensure that the paving work can be carried out smoothly, to ensure that the leveling reference point to choose, to ensure that the effect of rolling can meet the requirements of the provisions of the project, to keep the pavers can continue to be in a more efficient working condition.

In the paving process, if the paving speed is too fast, the quality of concrete paving is not guaranteed, if the paving speed is too slow, it will affect the efficiency of construction.

Therefore, the operating speed of the paver should be controlled, which is generally based on the power of the paver and the transportation efficiency of the concrete. In the process of paving, reversing or emergency stopping is not allowed, and after the paving work is finished, the mixture should be rolled.

  3.5 Maintenance of concrete

  After the completion of the paving and rolling operation, to ensure the quality and strength of the concrete, it is necessary to maintain it as soon as possible. The maintenance of concrete is mainly in the following aspects.

  (1) To ensure that the moisture and cement have enough time to react, the concrete should be maintained for a sufficient time.

  (2) after the paving and rolling of the mix is completed, the surface of the concrete should be covered with materials that have a moisturizing effect, more commonly used moisturizing materials such as plastic film, etc. In order to make the surface of the concrete can continue to be in a wet state, to use water to spray the surface.

  (3) In cutting the shrinkage joints, first of all, to ensure that the strength of the concrete to meet the requirements of the cut, in cutting in accordance with the design requirements to cut.

  4 Summary

  In the concrete construction work of water conservancy and hydropower projects, first of all, it should be clear that the concrete underwater is always subject to strong water pressure, in the construction of concrete so to improve the corresponding quality. Water is a permeable function, very easy to penetrate in the gap between the concrete layer, after the role of scouring lead to structural problems.

Therefore, the technique of rolling is used in construction to help eliminate gaps and improve the degree of compactness during the construction of concrete. The factors affecting the construction site need to be controlled in concrete construction. For example, water, humidity. Temperature, etc. After the completion of the construction, the maintenance of concrete is also very important, do a good job of sprinkling water maintenance work to ensure that the full reflection of cement and water end, do a good job of cutting joints in the concrete body, to prevent the concrete heat up and cold shrinkage on the safety of the dam has a greater impact.

Exploring the construction technology of clear concrete formwork in construction projects

To effectively improve the quality of the building itself, it is necessary to take reasonable concrete materials in the implementation of the building construction process, which has led to a great increase in the importance of concrete in the construction industry now. Together with the fact that the optimization of the concrete structure used in the construction industry has now become a necessary means of maintaining the stability of the building, this requires the adoption of reasonable methods to enhance the quality of the building surface.

In the process of implementing concrete construction, fair-faced concrete plays a very important role in the overall concrete construction. It is necessary to consider not only the condition of the building itself, but also the energy efficiency and environmental protection of the building construction. And in the in-depth study of fair-faced concrete, it is found that this concrete itself has certain construction advantages, which requires in-depth study of fair-faced concrete to ensure that its application in the construction industry has a certain expansion.

1 Clearwater concrete formwork construction analysis

In the process of trying construction projects, in order to fully improve the quality of the building itself, it is necessary to conduct in-depth research on construction materials to ensure that the corresponding quality can meet the needs of social development. The use of fair-faced concrete in the construction of buildings has made this building material widely used in the process of building construction because of its ability to effectively solve the problem of frame construction cost in the construction of buildings.

However, in an in-depth study of fair-faced concrete, it was found that there are still some problems in the process of its use, which are mainly manifested in the fact that its own quality cannot be reasonably guaranteed. The main reason is that fair-faced concrete does not need to be decorated and framed in the process of pouring, which often leads to the problem of angularity when finishing the pour. Therefore, it is necessary to pay high attention to the quality of the whole formwork when carrying out the construction of fair-faced concrete, so that fair-faced concrete can be more widely used in the construction of buildings in China.

1.1 Analysis of formwork construction

For fair-faced concrete, mainly includes in the process of construction of the building used once the type of concrete, and in the process of construction does not require a second treatment and the corresponding decoration, greatly reducing the work procedures in the construction of concrete, to reduce the construction time to play a very important role. Clear concrete has its own angular characteristics, which makes the process of concrete manufacturing very simple.

1.2 Principle of fair-faced concrete formwork construction

To ensure that fair-faced concrete plays its best role in the construction of buildings, it is necessary to have a comprehensive understanding of the overall state of the building during construction, and in this process, it is also necessary to analyze the structural state of fair-faced concrete itself to ensure that it can be fully integrated with the construction of buildings. The formwork construction also requires effective accounting of the formwork form to ensure the accuracy of the formwork construction. After the construction is completed, the formwork should be effectively reinforced to achieve the purpose of enhancing the stability of the building itself.

2 Clearwater concrete formwork construction points

To ensure that fair-faced concrete can be used to its fullest potential in the construction of a building, it is necessary to give full consideration to the technical methods chosen during the construction process. A comprehensive study of the overall structure of the building is also needed before construction to ensure the accuracy of the construction.

In-depth analysis of fair-faced concrete shows that there are some differences between it and traditional concrete, so it is necessary to analyze the steps and other properties of fair-faced concrete in order to ensure the smoothness of concrete laying. In addition, it is necessary to analyze the load-bearing capacity of fair-faced concrete formwork in the actual construction process, so that the construction of fair-faced concrete can be carried out more smoothly.

2.1 Construction attention measures

2.1.1 Positioning measures.

Before assembling the column and wall formwork, according to the column and wall border line popped out on the floor, 150mm from the ground in the vertical reinforcement welded 12mm-16mm diameter bars as positioning bars.

2.1.2 Anti-overturning measures.

In the column, wall formwork height of the upper, middle and lower three (not more than @ 1500mm) set up three diagonal brace, using the ground when pouring Ф48 steel pipe fixed points, as a template anti-overturning measures.

2.1.3 Anti-joint misalignment measures.

Outside the mouth of the column, wall and pipe wells, elevator shaft wall connected to the upper and lower joints, in order to prevent joints, hew misalignment, formwork lengthening downward hanging 60mm, every 200mm open 20mm wide slot, using 12mm diameter bolt head bent into a round hook, hooked in the column, the wall on the inside of the vertical reinforcement, bolt tightening to ensure that the upper and lower hew smooth without stack marks.

2.2 Protection measures of the formwork

2.2.1 Protection measures of reinforcing steel project on the template:

in the process of rebar sampling, it is necessary to ensure the accuracy of the sampling, as well as the accuracy of the processing size, during the transportation of this type of semi-finished products, sack lines and wooden boards should be used to play the effect of pad protection, to avoid the maximum direct dragging of reinforcing steel on the template.

During the rebar bundling, the corresponding wall and column rebar must be corrected by means of a drop hammer, and after correction, the rebar should be spot-welded directly to the beam rebar points to ensure the accuracy of the rebar itself; if there is a redundant part in the process of rebar placement, then the redundant member should be bent inward directly to avoid the possibility of exposure after the construction is completed. Exposure will lead to the phenomenon of rust spots, which will affect the quality of the reinforcement and the aesthetics of the surface.

2.2.2 Installation of pre-buried protection measures for the formwork:

it is important to coordinate all aspects of the installation of plumbing and electrical engineering to avoid the phenomenon of openings in the formwork, as far as possible, the pipeline concealed buried treatment; pre-buried pipe welding operations must be protected with thin iron or wet sacks underneath the welding, to ensure that the welding slag does not splash down on the formwork, so as not to affect the quality of the appearance of the concrete forming.

2.3 Removal of formwork and maintenance of formwork

2.3.1 Acceptance requirements before formwork dismantling:

Based on the compressive strength parameters of concrete specimens cured under exactly the same conditions, the appropriate dismantling of the formwork is determined. For example, some of the side forms without load-bearing effect can be removed directly when the strength of the concrete itself has reached 25%.

In this way, we can ensure that the structure will not be deformed after demoulding, and maintain the integrity of the angles; concrete load-bearing slabs within the span range of 2m can be removed if their strength reaches 50% of the expected design strength; beams and slabs in the span range of 2m-8m need about 75% of the design strength before they can be demolished; beams and slabs above 8m need to be demolished if their strength reaches 25% of the expected design strength. The load-bearing structures above 8m must reach 100% of the design strength before they can be demolished. Different demolition standards are mainly based on the load-bearing importance of the components themselves to be divided.

2.3.2 Strictly control the demolition time:

the demolition time should be determined according to the strength of concrete specimens, combined with the structural members of different parts for calculation to determine the demolition time and program. For example: for column wall mold, after 24h of concrete casting, the mold should be demolished only when its own strength can ensure that the members are not deformed and the angles are intact; the side mold of clear concrete structure should be demolished after 48h, etc.

Conclusion

In summary, it can be seen that, in the process of continuous development of the construction industry, the application of fair-faced concrete plays a very important role in improving the quality and beauty of the building itself. In the process of taking fair-faced concrete for construction, it is also necessary to have a comprehensive understanding of the overall structure of the building and the corresponding parameters of the concrete, so as to make the fair-faced concrete more widely used in building construction.

Discussion on the support technology of cement pile wall in construction project

Cement soil pile wall support technology is more often used in construction projects, in order to ensure the quality of construction, this technology needs to be constantly optimized and improved, but also combined with the actual situation of the construction project, using the principle of construction according to local conditions. The use of continuous cement pile wall can increase the stability of the slope of the building; the application of cement pile wall support technology can also avoid the collapse of the side soil. The reasonable use of machinery and equipment can speed up the rate of pile formation. The following author briefly introduces the practical application of cement pile wall support technology for reference.

1 cement soil pile wall support technology application requirements

1.1 Building materials

In the application of cement soil pile wall support technology in construction projects, first of all, we must choose suitable raw materials, in ordinary building construction, mostly used is ordinary silicate cement, using coarse or medium sand, and the mud content of not more than 5%, in the process of mixing will also use the coagulant and curing agent, these materials must have the inspection certificate, and also need to be tested at the scene to determine the relevant indicators, so as to To ensure the safety of building construction.

1.2 Mixing ratio

When using cement soil pile mixing technology, but also to control the ratio of raw materials, the general amount of cement mixing for the overall reinforcement of the weight of the soil pile 6-14%, reinforced 1 m 3 soil pile also mixed with 110-160kg of cement, water-cement ratio should be maintained at about 0.42-0.50. When cement mortar is used as the curing agent, it is also necessary to use sand and gravel, and in order to ensure the fluidity of the mixture, a certain proportion of calcium lignin sulfate is usually mixed.

1.3 Mechanical equipment

The application of cement soil pile wall support technology, also need to cooperate with the use of mechanical equipment, commonly used are: GZB-600 deep mixing equipment, mortar mixer, piling equipment, etc.; small tools include: tachometer, flow meter, guide frame, etc.

2 Site construction requirements

2.1 Site

The construction site needs to be guaranteed to be flat and neat. The construction unit needs to clean up the construction site before entering the site, clear out all some obstacles, and also use clay to fill the low-lying position in the site, and then compact it.

2.2 Indicators

In order to ensure the quality of construction, it is also necessary to determine the indicators of construction equipment, including the total amount of mixing equipment and pump body transportation, mixing time, lifting rate of cranes, etc. When mixing raw materials, it is also necessary to determine the matching ratio to ensure that all indicators meet the construction requirements.

2.3 Inspection and repair

When using machinery and equipment, in order to ensure the continuity of use, machinery and equipment should be overhauled in advance, and also carefully checked before entering the field to ensure the smoothness of the transport pipeline to avoid other unexpected situations in the process of construction.

3 Precautions for the application of cement pile wall support technology

In order to ensure the application of cement pile wall support technology, the construction unit needs to operate in accordance with certain processes, after the transport of machinery and equipment to the designated location, the first mixing of raw materials, check the sinking process; also configure the cement slurry, enhance the height of the slurry spray, and then mixing again; in the use of deep mixing equipment, but also constantly repeat mixing, lifting mixing; after removing the equipment from the construction site, the Need to do a good job of cleaning up.

After transporting the machinery and equipment to the construction site, the verticality of the frame of the mixer should also be adjusted, and after the mixer runs normally, the lifting equipment wire rope can be relaxed appropriately; the mixer is generally along the frame for cutting soil sinking mixing, the rate needs to be controlled at 80cm/min, in the process of mixing if it encounters hard soil, it will make the sinking rate lower, then the transport slurry pipe can be used to To make up water, so as to achieve the drilling requirements. After the mixer sinks to the specified depth, the mortar pump body can be opened for slurry spraying, the construction personnel need to control the height of the mixer, so that it generally rotates while spraying slurry, after stopping the slurry spraying, but also to discharge all the slurry in the aggregate hopper.

In the process of construction sometimes will attend the phenomenon of segregation, which greatly affects the quality of construction, the construction unit must do a good job of preventive measures, in lifting raw materials, should ensure the stability of the equipment, in accordance with the provisions of the control of the mixing rate and the number of times to ensure the uniformity and continuity of mixing. The construction unit should also control the grouting volume, and when encountering the sinking problem during the first mixing, it should not be flushed directly, but only after encountering the hard soil layer which causes the sinking rate to be reduced, the appropriate amount of flushing can be carried out. After the application of cement soil pile wall support technology, the equipment should also be flushed to avoid the problem of pipe blockage.

4 Cement soil pile wall support technology construction standards

4.1 Width and depth standard

The construction standard of cement soil pile wall support technology includes several aspects. When applying this technology, the construction personnel should first determine the standard of width and depth of the wall, and the value of width and depth of the wall is calculated based on the depth of the pit, construction soil environment and physical properties, ground load, environment, etc. In the clay soil environment, if the excavation depth of the pit is less than or equal to 5m, the depth value D=(0.7-1.1)h0 and the width value B=(0.5-0.7)h0 can be derived from experience, and the insertion depth can be slightly different between the front and rear rows.

4.2 Mixing ratio standard

When deep mixing equipment is applied to repeat mixing operation, the mixing ratio of cement is generally about 14-17% of solid soil density. When using powder spraying for deep mixing, the mixing ratio of cement is generally about 12-15% of the solid soil density. In order to better improve the rigidity of the cement soil wall, H-shaped reinforcement can be placed inside the mixing pile, which can not only improve its wall loading force, but also become a support wall structure with seepage resistance, generally applied in 8-10m deep pits with a cement mixing ratio of about 20%. In addition, when performing cement soil wall support technology, the high-pressure jet grouting pile method can be applied for operation. In order to ensure the effect of application, test spraying experiments will be conducted first to calculate the minimum diameter of the spray solid structure of different soil layers, high pressure construction technical parameters and other data, and the application of high pressure jet grouting pile method for construction, the water-cement ratio is generally controlled at about 1.0-1.4.

4.3 Foundation pit excavation standard

Application of cement pile wall support technology, need to ensure that the age of the foundation pit in more than 28d, when the strength of the foundation pit to meet the design requirements before it can be excavated. In the current society, there are more and more high-rise buildings and super high-rise buildings in the city, and the aesthetics of the buildings are getting stronger and stronger. In order to improve the utilization rate of land resources, the construction industry has also strengthened the use of underground space, and many buildings are equipped with basements, so when excavating the foundation pit, it is necessary to ensure the stability of the foundation, otherwise it will bring greater safety risks. Excavation of the foundation pit also needs to take into account the construction environment and understand the groundwater level of the construction site. Cement pile wall support technology can ensure that the wall can achieve the effect of retaining soil as well as seepage resistance, and it has the advantages of simple operation and convenient construction, and the raw materials used in construction are relatively small, which effectively reduces the cost, but there will be a larger problem of displacement, so in the process of deep foundation pit excavation, it is necessary to reasonably apply materials such as intermediate piers to control the displacement, so as to ensure the application effect of support technology.

Conclusion

Society is constantly progressing, construction projects are also increasing, the beauty of the building is getting stronger and stronger, in order to ensure the safety of the building use, the construction unit also needs to reasonably apply the construction technology. Cement pile wall support technology is an effective measure to ensure the stability of the building wall, in the application of this technology, the relevant system is more and more perfect, the building safety is also more and more high, which is conducive to ensuring the safety of people’s lives and property. This paper introduces the precautions for the application of cement pile wall support technology, and building construction units must combine the actual situation and reasonably apply this construction technology, so as to improve the overall construction quality of China’s construction industry.
