Ultra-deep foundation pit support close to river-sea water-rich deep soft soil layer and construction method of ultra-deep foundation pit support
The invention relates to the technical field of foundation pit supporting, and particularly discloses an ultra-deep foundation pit supporting close to a river-sea-rich water deep and thick soft soil layer and a construction method thereof.The ultra-deep foundation pit supporting close to the river-sea-rich water deep and thick soft soil layer comprises a slope wall of a foundation pit, the slope wall comprises a slope top face, a slope face, a platform face and a slope bottom face, a first drainage ditch is formed in the slope top face, and a second drainage ditch is formed in the platform face; a third drainage ditch, a first drainage ditch and a second drainage ditch are formed in the slope bottom face, a water collecting well is formed in the third drainage ditch, a first water pumping assembly is further arranged on the side, away from the foundation pit, of the first drainage ditch, and a second water pumping assembly is arranged in the water collecting well; the first drainage ditch, the second drainage ditch and the third drainage ditch can reduce the influence of rainwater on construction of the foundation pit, the first drainage ditch, the second drainage ditch and the third drainage ditch can guide the intercepted rainwater into the water collecting well, then the rainwater is drained out of the water collecting well through the second water pumping assembly, and the first water pumping assembly can pump underground water around the foundation pit; therefore, the water content of underground water around the foundation pit is reduced.
本申请涉及基坑支护技术领域，具体公开了紧邻河海富水深厚软土层超深基坑支护及其施工方法，包括基坑的坡壁，坡壁包括坡顶面、放坡面、平台面和坡底面，坡顶面上开设有第一排水沟，平台面上开设有第二排水沟，坡底面上开设有第三排水沟，第一排水沟、第二排水沟、第三排水沟上开设有集水井，第一排水沟远离基坑的一侧还设置有第一抽水组件，集水井中设置有第二抽水组件；本申请中第一排水沟、第二排水沟和第三排水沟可减小雨水对基坑的施工造成的影响，第一排水沟、第二排水沟和第三排水沟可将拦截的雨水引流至集水井中，再由第二抽水组件排出集水井，第一抽水组件可对基坑周围的地下水进行抽取，从而降低基坑周围地下水的含水量。
