Dewatering well structure and dewatering well construction method
The invention belongs to the technical field of building drainage, and particularly discloses a dewatering well structure and a construction method thereof.The dewatering well structure comprises a dewatering pipe arranged in a well body; the downcast pipe and the well body are coaxially arranged, and a gap is reserved between the downcast pipe and the well body; the gap is filled with gravel to form a gravel filter layer; the top of the gravel filter layer extends to the position 2-4 m below the ground, clay is further arranged in the gap to form a clay plugging layer, the clay plugging layer is located at the top of the gravel filter layer, and the top of the clay plugging layer is flush with the ground; a submersible pump is further arranged at the bottom of the downcast pipe, connected with ground equipment through a cable and used for pumping underground water in the downcast pipe to a designated area on the ground. The downcast pipe composed of the solid pipe, the clamping base and the base is adopted, convenience is provided for underground water to flow into the downcast pipe, meanwhile, silt can be filtered out as much as possible through the fastening layer of the metal net-shaped structure and the filtering layer, the downcast pipe is suitable for various soil layers, and the downcast effect is remarkable.
本发明属于建筑排水技术领域，具体公开了一种降水井结构及其施工方法，包括设置在井体内部的降水管；降水管与井体同轴设置且降水管与井体之间预留有间隙；间隙内填充有砾石形成砾石滤层；砾石滤层的顶部延伸至地面以下2‑4m处，间隙内还设置有黏土，形成黏土封堵层，黏土封堵层位于砾石滤层顶部，且黏土封堵层的顶部与地面平齐；降水管底部还设有潜水泵，潜水泵与地面设备通过电缆连接，用于将降水管内的地下水抽至地面指定区域。本发明通过采用实心管与卡座以及底座构成的降水管，为地下水流入降水管提供了便利，同时通过金属网状结构的紧固层以及过滤层又可以尽可能过滤掉泥沙，适用于各种土层，降水效果显著。
