Deep foundation pit layered dewatering structure
The invention relates to a deep foundation pit layered dewatering structure, and belongs to the technical field of civil engineering underground construction. The problem that layered detailed dewatering cannot be conducted on all soil layer parts of the deep foundation pit through existing tube well dewatering is solved. The method comprises the following steps: splicing and mounting the multi-stage water filter pipe, the water separation plate and the open caisson pipe on a construction site; burying a well casing, and filling a filter material between the well casing and the hole wall; the deep-well pump is put into a well, well-point dewatering is conducted according to different soil layers and needed dewatering depths, after well-point dewatering of the upper soil layer is completed, the waterproof plate is broken according to different depth requirements, the deep-well pump continues to be put down, dewatering of the lower soil layer is achieved, and layered well-point dewatering is achieved. According to the well casing, the ultra-deep foundation pit and complex geological conditions are comprehensively considered, layered precipitation can be conducted on different soil layers and depths, the well casing is convenient to disassemble and assemble, the construction speed is high, the construction period is shortened, the cost is reduced, the precipitation quality is improved, and the social and economic effects are remarkable.
本发明涉及一种深基坑分层降水结构，属于土建地下施工技术领域。它解决了现有管井降水无法对深基坑各土层部位进行分层细部降水的问题。该方法包括：在施工现场进行多级滤水管、隔水板块和沉井管的拼接安装；埋设井管、并在井管与孔壁之间填充滤料；将深井泵下放入井内，根据不同土层及所需要降水深度进行井点降水，待上部土层井点降水完成后根据不同深度要求破碎隔水板块并继续下放深井泵，实现下部土层降水以实现分层井点降水。本发明针对超深基坑及复杂地质条件进行综合考虑，能够对不同土层及深度进行分层降水，并且该井管拆装方便、施工速度较快、节约工期、降低了成本、提高降水质量，社会经济效应显著。
