Deep foundation pit bottom seepage water open drainage method
The invention relates to the technical field of foundation pit construction, in particular to a deep foundation pit bottom water seepage open drainage method, which comprises the following steps: constructing a dewatering well between every two adjacent fender posts, then carrying out excavation construction on a to-be-formed area to form a current foundation pit, and arranging a water drainage pipe on the side wall of the current foundation pit, the current foundation pit continues to be excavated and constructed to the preset elevation, a pit bottom construction face of the deep foundation pit is formed, a drainage ditch and a water collecting well are constructed in the position, close to the side wall of the deep foundation pit, of the pit bottom construction face, the water collecting well and the dewatering well are connected, and finally accumulated water in the dewatering well is pumped out of the deep foundation pit. By means of the structure, the purpose of pumping and draining accumulated water or underground water in the deep foundation pit is achieved during use, and the problems that in the prior art, when deep foundation pit construction is conducted, due to the fact that accumulated water or underground water exists in the foundation pit, excavation is difficult due to accumulated water in the foundation pit during foundation pit excavation construction, and construction efficiency is high are solved. And the excavation construction efficiency of the foundation pit is influenced.
本发明涉及基坑施工技术领域，特别涉及一种深基坑坑底渗水明排方法，通过在所有相邻的两根围护桩之间施作降水井，然后对待成形区域进行开挖施工以形成当前基坑，在当前基坑的侧壁设置泄水管，继续对当前基坑开挖施工至预设标高，形成深基坑的坑底施工面，在坑底施工面靠近深基坑的侧壁处施作排水沟以及集水井，打通集水井和降水井的连接，最后将降水井中的积水抽排出深基坑，使得本发明在使用时实现了对深基坑内存在的积水或者地下水进行抽排的目的，解决了现有技术中存在的在进行深基坑施工时，由于基坑存在积水或者地下水，这就使得基坑开挖施工时存在因基坑积水而导致开挖困难，影响基坑开挖施工效率的缺陷。
