Foundation pit dewatering structure and method
The invention relates to the technical field of foundation pit dewatering, and provides a foundation pit dewatering structure and method.The foundation pit dewatering structure at least comprises a foundation pit; the three-axis stirring piles are arranged in the circumferential direction of the foundation pit so as to form a closed waterproof curtain on the periphery of the foundation pit; the first dewatering well is arranged in the foundation pit; and the first pneumatic dewatering pump is arranged in the first dewatering well and is suitable for pumping water in the first dewatering well out of the foundation pit. According to the foundation pit dewatering structure, the closed waterproof curtain is formed around the foundation pit through the three-shaft stirring piles, underground water is prevented from permeating into the foundation pit, meanwhile, water in the first dewatering well is pumped out of the foundation pit through the first dewatering well and the first pneumatic dewatering pump, the underground water is prevented from continuously permeating into the pit, and the foundation pit dewatering effect is improved. The problems of slope instability, quicksand, pit bottom upheaval, pit bottom piping, foundation bearing capacity reduction and the like are caused. And moreover, the construction cost is reduced, potential safety hazards are eliminated, and the field safe and civilized construction image is remarkably improved.
本发明涉及基坑降水技术领域，提供了一种基坑降水结构及方法，该基坑降水结构至少包括：基坑；三轴搅拌桩，沿基坑的周向设置，以在基坑的四周形成封闭的止水帷幕；第一降水井，设置在基坑内；第一气动降水泵，设置在第一降水井内，适于将第一降水井内的水体泵送至基坑外。本发明提供的基坑降水结构，采用三轴搅拌桩在基坑的四周形成封闭的止水帷幕，防止地下水渗透至基坑内，同时，通过第一降水井与第一气动降水泵，将第一降水井内的水体泵送至基坑外，防止地下水不断渗入坑内，导致边坡失稳、流砂、坑底隆起、坑底管涌和地基承载力下降等问题。并且，降低了施工成本,消除了安全隐患，显著提升了现场安全文明施工形象。
