Water-rich stratum foundation pit dewatering system and construction method
The invention relates to the technical field of foundation pit dewatering, and provides a water-rich stratum foundation pit dewatering system which comprises a water collecting header pipe, vacuum water pumping equipment, a well point pipe and a supporting pipe buried underground, the well point pipe is coaxially erected in the supporting pipe, and a plurality of water permeable holes are formed in the periphery of the supporting pipe; the water collecting header pipe is connected with vacuum water pumping equipment, the top end of the well point pipe is communicated with the water collecting header pipe, and a plugging piece is further arranged at the top end of the well point pipe and used for sealing a gap between the top of the supporting pipe and the top of the well point pipe. The method has the effect of reducing the situation that in the well point dewatering process, the well point hole collapses, and consequently follow-up well point pipe installation is affected.
本申请涉及基坑降水的技术领域，提出了一种富水地层基坑降水系统，包括集水总管、真空抽水设备、井点管以及埋设于地下的支撑管，所述井点管同轴架设于支撑管内，所述支撑管外周开设有若干透水孔；所述集水总管与真空抽水设备相连接，所述井点管顶端与集水总管相连通，所述井点管顶端还设置有封堵件，所述封堵件用于密封支撑管与井点管两者顶部间隙。本申请具有减少井点降水过程中，井点孔发生坍塌影响后续井点管安装的效果。
