Foundation pit drainage system for enriching karst fissure water and construction method
The invention discloses a karst fissure water-rich foundation pit drainage system and a construction method, relates to the technical field of foundation pit drainage, solves the problem that drainage cannot be conducted in time during karst fissure water-rich stratum foundation pit construction, and avoids structural construction area water accumulation caused by large underground water yield. According to the specific scheme, the structure comprises a replacement and filling water storage layer, drainage ditches and a water collecting pit which are arranged in a foundation pit, the replacement and filling water storage layer has a water storage function, the multiple drainage ditches are arranged at the bottom of the replacement and filling water storage layer and are transversely and longitudinally arranged in a crossed mode to form a net-shaped structure, and at least one drainage pipe is arranged in each drainage ditch; the water collecting pit is located at the bottom of the replacing and filling water storage layer, at least one water collecting tank is arranged in the water collecting pit, a well pipe is arranged on the top of the water collecting tank, a water pump is arranged in the water collecting tank, and a water pipe of the water pump extends out of the bottom plate through the well pipe.
本发明公开了一种用于岩溶裂隙水丰富基坑排水系统及施工方法，涉及基坑排水技术领域，解决了岩溶裂隙水丰富地层基坑施工无法及时排水的问题，避免了地下水出水量大导致的结构施工面积水，具体方案如下：包括布置在基坑内的换填蓄水层、排水沟以及集水坑，所述换填蓄水层具有储水功能，换填蓄水层的底部设有若干排水沟，若干排水沟横向、纵向交叉布置以形成网状结构，每个排水沟内至少设有一根排水管，所述集水坑位于换填蓄水层的底部，所述集水坑内至少设有一个集水箱，所述集水箱的顶部设有井管，集水箱的内部设有水泵，水泵的水管通过井管伸出底板。
