Foundation pit dewatering supporting structure and construction method
The foundation pit dewatering supporting structure comprises a well pipe pile arranged on the peripheral edge of a pre-excavated foundation pit, the lower portion of the well pipe pile is closed and provided with a tough foot, the well pipe pile is provided with a socket face, a supporting permeable face and a jaw with wings, a plurality of water seepage holes are evenly distributed in the supporting permeable face of the well pipe pile, and the water seepage holes are communicated with the well pipe pile. A water suction pipe is arranged in each well pipe pile, the outer end of each water suction pipe is connected with a bent connecting pipe, the bent connecting pipes are communicated with a water pumping header pipe, the water pumping header pipe is connected with a water pump, water in the well pipe piles is discharged through the water pumps, every two well pipe piles are meshed through a socket face and a wing jaw to form a continuous pipe pile wall, and the functions of supporting, water stopping and dewatering are achieved through the continuous pipe pile walls. The foundation pit supporting and dewatering technological process is simplified, and the construction problem that in the construction process of the building foundation pit with the high underground water level, steel sheet pile supporting and dewatering well building are needed at the same time for construction and dewatering is solved.
本发明公开了一种基坑降水支护结构及施工方法，包括有布置在预挖基坑周边边沿的井管桩，井管桩的下部封闭并且设置有韧脚，井管桩设置有承插面、支护透水面以及带翼钳口，井管桩的支护透水面上均布设置有多个渗水孔，井管桩内设置有吸水管，吸水管的外端连接有弯联管，弯联管与抽水总管联通，抽水总管连接有水泵，通过水泵将井管桩内的水排出，两两井管桩之间通过承插面、带翼钳口咬合，以形成连续管桩墙，通过连续管桩墙起到支护、止水、降水的功能。本发明简化了基坑支护及降水工艺流程，解决了在地下水位较高的建筑基坑施工过程中存在同时需要钢板桩支护和建造降水井进行施工降水的施工问题。
