Deep foundation pit underground water treatment structure and method
The invention discloses a deep foundation pit underground water treatment structure and method. The structure comprises a two-layer waterproof system and a three-layer dewatering system, wherein the two-layer waterproof system comprises a CSM waterproof curtain and a milling method underground diaphragm wall, and the lower end of the CSM waterproof curtain penetrates through a confined aquifer in a stratum and extends to a waterproof layer; the lower end of the underground diaphragm wall extends to the stable waterproof layer or a bedrock layer; the three-layer dewatering system comprises a first dewatering system, a second dewatering system and a third dewatering system, and the first dewatering system is used for draining underground water in the foundation pit; the second precipitation system is used for draining underground water between the two layers of waterproof systems; and the third dewatering system is used for decompressing and dewatering underground water in the foundation pit in combination with the foundation pit internal force and deformation monitoring result according to the excavation depth of the foundation pit and the seasonal change condition. The underground continuous wall and the CSM waterproof curtain adopting the milling method are adopted, so that the safety and the stability of the foundation pit can be effectively ensured; and meanwhile, the three-layer dewatering system is adopted, dynamic on-demand dewatering is achieved, and exploitation of underground water can be reduced.
本发明公开了一种深基坑地下水治理结构及方法。该结构包括两层隔水系统及三层降水系统，两层隔水系统包括CSM止水帷幕和铣接法地下连续墙，CSM止水帷幕的下端穿过地层中的承压含水层延伸至隔水层；地下连续墙的下端延伸至稳定隔水层或基岩层；三层降水系统包括第一降水体系、第二降水体系和第三降水体系，第一降水体系用于疏干基坑内地下水；第二降水体系用于疏干两层隔水系统之间的地下水；第三降水体系用于根据基坑的开挖深度和季节变化情况，结合基坑内力和变形监测结果对基坑内地下水进行减压降水。本发明采用铣接法地下连续墙和CSM止水帷幕，能有效确保基坑的安全和稳定性；同时采用三层降水系统，动态按需降水，能减少地下水的开采。
