Basement plugging construction measures in accordance with the importance and use of works in the basement of plugging requirements, determine underground works plugging basement levels, in different parts of the project for a "defense, row, cut, blocking" the combination of firmness and flexibility, according to local conditions, comprehensive way. 2.1 Anti-row combination of underground excavation using cement mixing pile retaining wall supporting gravity to form a seal around foundation curtain, and by precipitation design, arranged in a deep foundation pit precipitation points. Before basement excavation of earth, water pump started well group precipitation, making plugging in the underground basement concrete construction process, the water table remains in the basement plugging layer below 30cm. Surface water into the pit around the trench around the next to ensure that the structure of the basement in the basement with no water in mud plugging construction during construction. 2.2 determine the rigid basement plugging basement plugging basement concrete impermeability grade of concrete structures using self basement plugging UEA shrinkage-compensating concrete pumping, UEA mixed lot of 8% to 10% of cementitious materials. UEA limit expansion of 2 ~ 4 × 104-4 concrete strength can be increased by 10% to 30%, 2-fold increase impermeability, frost resistance, resistance to sulfate is also greatly improved, no corrosion of steel role There are advantages retarding effect can compensate for the temperature difference between concrete shrinkage, then mixed with water reducing retarding compound used is one of the best measures to reduce the large volume of concrete cracking, it can effectively suppress internal porosity of concrete, increase the density of the interface, so as to achieve the purpose of plugging basement. (1) large volume concrete foundation of integrity requirements, and therefore should be layered pouring concrete, layered vibration (generally 30cm ~ 40cm). 2.3 Flexible basement plugging basement plugging cement-based paint requirements grassroots level, clean, moist, have sufficient strength, yin and yang make rounded corner. Liquid and powder materials by 1:1 ratio and stir after use, with a good paint should be used up; the construction sequence for the first corner of yin and yang, such as an additional layer of detail enhancement processing node, then the facade construction. Construction, if too dry grass roots, rendering a material dilution required, the first pass coating should be thin, even when you need to coating. Usually 3 to 5 times the amount of (3 ~ 5) kg / m2. After the first pass coating is dry, the coating can be carried out a second time, the second time the coating direction should be perpendicular to the first pass. After various times and so on, until the coating thickness of 1.5mm. The coating composition containing cement, cement bonded easily with class material, therefore, can be protected in this coating layer of cement mortar construction, masonry materials, direct, subject to plugging in the basement after layer of hard work carried out. After completion of the basement wall basement plugging treatment, pit and the exterior space using cohesive backfill soil to change the environment, within the pit artificially reduce soil infiltration capacity, thus achieving the basement sealing purposes. After pouring the basement plugging with 2.4 after treatment with the concrete poured concrete with a part of the second phase of the concrete junction, basement plugging function in the weak parts, very easy to cause leakage, particular attention. Therefore, in order to prevent the emergence of vertical cracks in the foundation of the original design, and the other to increase the number of stretching after pouring belt to ensure that after pouring belt around 30m ~ 40m each set together. After pouring the thickness of the middle set with a long pass enclosed steel water stop, fully welded joints, after pouring belt to improve the quality of basement plugging. After pouring concrete at the front with the construction, the first wooden mold or fine wire mesh sides removed, clean the surface relatively loose concrete, surface roughening, moist than 48h, and check whether the leakage of plasma template. After pouring belt should be added at once basement plugging paint, according to design requirements and after pouring the floor with a layer of 100 shall also additional 1.4m wide concrete thick cushion inside with Φ 12 @ 200 bi-steel mesh. After pouring the concrete and construction interval situ concrete sides at least 2 months. After pouring concrete construction temperature should be lower than the temperature at both sides of the in-situ concrete construction, which is to reduce the temperature gradient inside the outer layer of concrete and concrete between the cracks due to shrink to reduce distortion arising under restrictions, effective After pouring with construction quality assurance. After the final setting of the concrete cover and water conservation were sacks, curing time is generally not less than l4d. 3 leakage control program at 3.1 facades leakage will tick chisel to clean exterior wall leaks, finding large leakage points, hit grouting eye, using 0.3Mpa pressure of Chemical Grouting, plugging mortar hollowing at the basement conduct tick chisel to clean and re-layered wipe 2mm ~ 3mm plain basement plugging paste (cement: basement plugging agent = 1:0.5 ~ 0.8), 10mm ~ 15mm basement plugging mortar (cement: sand: basement plugging agent = 1:2.5:0.8) each twice, basement plugging agents using fatty basement plugging fluid. 3.2 wall pipe leak at the pipe wall around the loose concrete drilling, clean up after, with a basement plugging caulking ointment for basement plugging perfusion condensate layer, and then wipe 2mm ~ 3mm stratified basement plugging hormone Pulp, 10mm ~ 15mm mortar basement plugging twice. 3.3 Construction joints leak will leak along the seam construction joints gouges, after clean up leaking buried at the site of a large water management, the inner seam seam major leak leads outside, then hit grouting eyes were 0.3Mpa pressure chemical grouting, with rapid plugging Ling do 5mm ~ 10mm basement sealing layer, and then layered basement plugging wipe 2mm ~ 3mm thick liquid, 10mm ~ 15mm mortar basement plugging twice. 3.4 Other leakage for the venue, the actual situation of leaking water pipes were processing pipeline, so as to achieve no leakage, while strengthening organized drainage work around the building, additional drains, atmospheric precipitation, surface water can Organized discharged to outside the scope of the project, in order to lower the water table, reducing the pressure on underground structures, so that the underground basement plugging engineering from erosion damage. 4 Conclusion basement plugging construction is an important part of the construction works in the basement plugging. Leakage for different projects, in the "defense, row, cut, blocking" the combination of firmness and flexibility, comprehensive management governance principles to ensure the quality of construction projects basement plugging.
