Construction method of temporary drainage system on deep foundation pit engineering construction site
The invention discloses a construction method of a temporary drainage system on a deep foundation pit engineering construction site. The drainage system comprises a top beam, a retention wall and a retaining wall, and the retention wall, the retaining wall and the top beam form a top beam drainage channel with the upper portion open. Water collecting wells are arranged on the outer side of the retaining wall in the length direction of the top beam at intervals, and water collecting pipes communicated with the drainage channel of the top beam are arranged on the lower portions of the water collecting wells. A water guide slope is arranged at the top of the crown beam in the crown beam drainage channel; a three-stage sedimentation tank connected with a municipal drainage pipe network is arranged on the outer side of the retaining wall at the lowest position of the crown beam drainage channel, and the three-stage sedimentation tank is connected with the crown beam drainage channel through a sewer pipe; the construction method solves the problems that an existing foundation layer soil body is influenced by deep foundation pit excavation, the top of the existing foundation layer soil body bears a large driving load, certain differential settlement and damage accidents happen, and the phenomena of damage and leakage of the drainage system are likely to happen; the method which influences the safety of underground pipelines and construction roads is optimized and improved.
本发明公开了一种深基坑工程施工现场临时排水系统施工方法，该排水系统包括冠梁、挡水墙和挡土墙，挡水墙和挡土墙与冠梁形成上部开放的冠梁排水通道；在挡土墙外侧沿冠梁的长度方向间隔设有集水井，所述集水井的下部设有与冠梁排水通道连通的集水管；在冠梁排水通道内冠梁的顶部设有导水坡；在冠梁排水通道最低处的挡土墙外侧设有与市政排水管网连接的三级沉淀池，所述三级沉淀池通过下水管连接冠梁排水通道；还包括建立上述排水系统的施工方法，本发明解决现有基础层土体受深基坑开挖影响且顶部承受较大行车荷载，发生一定的不均匀沉降、破坏事故，容易导致排水系统出现破坏、渗漏现象；对于影响地下管线、施工便道安全性的做法进行优化改善。
