Construction method of ultra-deep foundation pit controlled precipitation system
The invention relates to a construction method of an ultra-deep foundation pit controlled precipitation system. The construction method comprises the following steps: constructing a foundation pit support structure; constructing a precipitation well, a water level observation well and a recharge well; constructing drainage ditches; excavation construction of a foundation pit; sealing the water level observation well; and sealing the dewatering well. The method has the beneficial effects that tap water is adopted for conducting pressurization recharge treatment on the recharge well, the overall stability of the ground environment around the foundation pit is improved, and ground subsidence is reduced; a shaped sewage intercepting groove structure is mounted in the prefabricated drainage ditch, so that the pipeline blockage phenomenon is reduced; positioning and adjusting the mounting position of the well casing of the dewatering well by adopting a guide bracket; after the foundation pit is excavated, the dewatering well and water level observation well structure is blocked, the blocking construction efficiency and construction quality of the dewatering well and the water level observation well are improved, and the water leakage phenomenon of a foundation pit bottom plate is reduced.
本发明涉及一种超深基坑控制性降水体系的施工方法，包括步骤：基坑围护结构施工；降水井、水位观察井和回灌井施工；排水沟施工；基坑开挖施工；水位观察井封闭处理；降水井封闭处理。本发明的有益效果是：采用自来水对回灌井进行加压回灌处理，提高基坑周边地面环境整体稳定性，减少地面沉降；在预制装配式排水沟内安装定型化截污槽结构，减少管道堵塞现象；采用导向支架对降水井井管安装位置进行定位调整；基坑开挖完成后对降水井和水位观察井结构进行封堵处理，提高降水井和水位观察井封堵施工效率和施工质量，减少基坑底板的渗漏水现象。
