Foundation pit groove bottom dewatering method
The invention discloses a foundation pit groove bottom dewatering method, a foundation pit groove bottom pump burying dewatering structure is adopted, and the foundation pit groove bottom pump burying dewatering structure comprises a water pump burying area which is excavated downwards from the foundation pit groove bottom and a water pumping pipe guide groove which is excavated from the water pump burying area to one side. The water pump is arranged in the water pump burying area and filled with pebbles and gravels in sequence, and waterproof cloth is arranged on the water pump burying area. A water pumping pipe of the water pump and broken stones are arranged in the water pumping pipe guide groove. The water pumping pipe is led out through the buried pump for dewatering, so that a well casing is omitted, the problems of later leakage of the well casing and adverse effects on building use caused by untight well sealing of the drainage well are solved, later well sealing is avoided, the construction period is shortened, and the manufacturing cost is saved. Meanwhile, the problems of large underground water amount and inconvenient construction in the local area of the base are solved.
本发明公开了一种基坑槽底降水方法，采用一种基坑槽底埋泵降水结构，该基坑槽底埋泵降水结构包括自基坑槽底向下挖掘的水泵埋设区域和自水泵埋设区域向一侧挖掘的抽水管导槽。水泵埋设区域内设置有水泵、依次填充有卵石和碎石，上部设置有防水布。抽水管导槽内设置有水泵的抽水管和碎石。本发明通过埋泵引出抽水管进行降水，以取消井管，解决因疏干井封井不严密造成井管后期渗漏以及给建筑物使用带来的不利影响，避免后期封井，节省工期、节约造价。同时解决基底局部区域地下水量大，施工不便的问题。
