Dewatering construction method for confined water depth foundation pit
The invention provides a dewatering construction method for a confined water depth foundation pit, and belongs to the technical field of foundation pit construction.According to the dewatering construction method, a casing pipe is hoisted after hole forming, well wall collapse can be prevented, safety in a well can be guaranteed, after the filter material filling procedure is completed, the casing pipe part is pulled out, part of the casing pipe is reserved to form an upper section and a lower section, and the casing pipe part is taken out; the upper section and the lower section do not affect normal underground water overflow, the stability of the confined water depth foundation pit can be guaranteed, in the construction process of the deep foundation pit, the construction difficulty can be lowered, well washing and water pumping equipment installation and water pumping test steps can be reduced, the working state of a well pipe can be monitored in real time, problems can be found and solved in time, and the construction quality is guaranteed; through well casing plugging, construction monitoring and emergency measures, quick response can be achieved when abnormal conditions occur, and possible risks can be effectively handled. Through a series of construction steps and technical means, the stability and reliability of precipitation construction are ensured, and the engineering safety is improved.
本发明提供承压水深基坑降水施工方法，属于基坑施工技术领域，本方法采用成孔后吊放套管，能够防止井壁塌陷和保证井内安全，并在填滤料工序完成之后，将套管部分拔出，并预留形成部分套管形成上、下分节，该上、下分节既不会影响正常的地下水溢流，也能够保证承压水深基坑的稳定，在深基坑施工过程中，能够降低施工的难度，洗井安装抽水设备和抽水试验步骤，可以实时监测井管的工作状态，及时发现并解决问题，确保施工质量；通过井管封堵、施工监测和应急措施，可以在出现异常情况时迅速响应，有效应对可能出现的风险。通过上述一系列的施工步骤和技术手段，确保了降水施工的稳定性和可靠性，提高了工程的安全性。
