Deep soft foundation pit dewatering well and construction method
The deep soft foundation pit dewatering well comprises a well hole formed underground, a first well pipe is arranged in the well hole, a plurality of water inlet holes are formed in the peripheral side wall of the first well pipe, the outer wall of the first well pipe is wrapped with geotechnical cloth, and each water inlet hole is covered with the geotechnical cloth; a gravel filtering layer is arranged between the outer wall of the geotechnical cloth and the inner wall of the well hole, a submersible pump is installed in the bottom end of the first well pipe, the water outlet end of the submersible pump is connected with a drainage pipe, a cover plate is arranged at the top end of the first well pipe, and an installation sleeve is fixedly installed on the bottom face of the cover plate and arranged at the top end of the first well pipe in a threaded and sleeving mode. A first sealing ring is fixedly installed at the top end of the first well pipe, an air pump is fixedly installed on the top face of the cover plate, the air inlet end of the air pump communicates with the interior of the first well pipe, and the end, away from the submersible pump, of the drainage pipe slidably penetrates through the cover plate. The device has the effect of improving the rainfall speed of underground water.
本申请涉及一种深层软基基坑降水井及施工方法，其包括开设于地下的井孔，井孔内部设置有第一井管，第一井管的周侧壁开设有多个进水孔，第一井管的外壁包裹有土工布，土工布覆盖每一进水孔，土工布的外壁与井孔的内壁之间设置有砂石滤层，第一井管底端的内部安装有潜水泵，潜水泵的出水端连接有排水管，第一井管的顶端设置有盖板，盖板的底面固定安装有安装套筒，安装套筒螺纹套设于第一井管的顶端，第一井管的顶端固定安装有第一密封环，盖板的顶面固定安装有抽气泵，抽气泵的进气端与第一井管内部连通，排水管远离潜水泵的一端滑动贯穿盖板。本申请具有提高地下水的降水速度的效果。
