Drainage structure for sump and elevator foundation pit and construction method
The invention discloses a drainage structure for a sump and an elevator foundation pit and a construction method, and belongs to the technical field of underground structure construction. According to the construction method, when the basement sump or the elevator foundation pit is excavated, a small sump chamber is excavated beside the foundation pit, a cushion layer in the sump chamber and a waterproof method are the same as the sump or the elevator foundation pit, when it rains, a water pump is placed in the small sump chamber to timely drain accumulated water at the bottom of the sump, after reinforcing steel bars of a raft plate and the sump or the elevator foundation pit are bound, it is ensured that no accumulated water exists in the foundation pit, then raft plate concrete is poured, and the small sump chamber is poured firmly together, and therefore, the concrete pouring quality in the foundation pit can be guaranteed, and the waterproof performance of concrete is guaranteed; and accumulated water in the sump or the elevator foundation pit can be effectively guaranteed to be completely discharged, the concrete pouring quality is guaranteed, and the waterproof performance of a basement bottom plate is guaranteed.
本发明公开了一种用于集水坑和电梯基坑的排水结构及施工方法，属于地下结构施工技术领域。本发明是在地下室集水坑或电梯基坑开挖时，在基坑边开挖一个小的集水室，集水室内垫层、防水做法与集水坑或电梯基坑相同，在遇到下雨时，通过在小集水坑内放置水泵及时排除坑底积水，在筏板及集水坑或电梯基坑钢筋绑扎完成后，确保基坑无积水，然后浇筑筏板混凝土，小集水坑一起浇实。这样能够保证基坑内混凝土浇筑质量，保证混凝土的防水性能。本发明能够有效保证集水坑或电梯基坑内积水全部排出，确保混凝土浇筑质量，保证地下室底板的防水性能。
