Foundation pit drainage system combined with deep and large foundation pit inner support
According to the foundation pit drainage system combined with the deep and large foundation pit inner support, a foundation pit steel drainage vertical pipe is arranged at the position, close to a sedimentation tank, of a foundation pit first-layer trestle plate, the foundation pit steel drainage vertical pipe extends into a base water collection pit along a foundation pit supporting structure, and water collection and exposed drainage in the pit are achieved. And the foundation pit steel drainage vertical pipe on the second/third concrete support of the foundation pit is connected with a steel drainage horizontal pipe which is communicated with a water collecting tank to collect foundation pit rainfall and open water of a first-layer trestle plate, and the rainfall and the open water are drained to a sedimentation tank through a submersible pump. Concrete water retaining ridges are arranged at the edge positions of the first-layer trestle plate, trestle lateral steel drainage vertical pipes are installed, and the trestle lateral steel drainage vertical pipes penetrate through the supporting beam latticed columns and then stretch into the water collecting tank to drain open water in the first-layer trestle plate. And dewatering of the dewatering well in the foundation pit is pumped and discharged to the nearby water collecting tank through the dewatering pump and finally discharged to the sedimentation tank. The foundation pit drainage system is not affected by the external construction environment, the problem that drainage pipelines in a traditional foundation pit drainage system are arranged disorderly is solved, the drainage pipelines are steel drainage pipelines, and leakage and leakage are avoided.
本发明提供一种与深大基坑内支撑相结合的基坑排水系统，基坑首层栈桥板上靠近沉淀池的位置设置基坑钢制排水立管，其沿着基坑支护结构延伸至基底集水坑中，实现坑内集水明排。基坑第二/三道混凝土支撑上的基坑钢制排水立管连接有钢制排水平管，其与集水箱连通，收集基坑降水及首层栈桥板明水，并通过潜水泵排至沉淀池。首层栈桥板临边位置均设置混凝土挡水坎，并安装栈桥侧向钢制排水立管，其穿过支撑梁格构柱后伸入集水箱，排出首层栈桥板内明水。基坑内降水井降水通过降水水泵抽排至就近集水箱，并最终排至沉淀池。本发明不受外部施工环境影响，解决了传统基坑排水系统中排水管线布置混乱问题，排水管线采用钢质排水管，不会跑冒滴漏。
