Basement drainage pipeline system for preventing rainstorm from flowing backwards
A drainage pipeline system for preventing rainstorm from flowing backwards in a basement comprises a drainage pump and a check valve, the drainage pump is arranged in a sump, a water outlet of the drainage pump is communicated with an inlet of the check valve through a drainage pipe behind the pump, an outlet of the check valve is communicated with an inlet of a gate valve, and an outlet of the gate valve is communicated with an inlet of the drainage pipe behind the pump. An outlet of the downstream drainage pipe penetrates through the indoor floor of the bottom layer of the building, extends out of the outer wall and is communicated with an inlet of a siphon eliminator arranged at the highest position of the drainage pipeline, and an outlet of the siphon eliminator is communicated with a municipal drainage inspection well through a downstream drainage pipe. In addition, the invention further provides an emergency drainage system suitable for the densely populated basement. The device is simple in structure and scientific and reasonable in design, outdoor accumulated water cannot flow backwards into the basement no matter what accidents occur, including the fact that the check valve is clamped, the gate valve is normally opened and even the drainage pipe is suddenly broken, rainstorm is effectively prevented from flowing backwards into the basement, and huge social and economic benefits are achieved.
一种地下室防止暴雨倒灌的排水管道系统，包括排水泵和止回阀，所述的排水泵置于集水坑中，排水泵的出水口经泵后排水管与止回阀进口相连通，止回阀出口与闸阀进口相连通，闸阀出口与阀后排水管进口相连通，阀后排水管出口穿过建筑物底层室内地坪，伸出外墙并与置于排水管道最高处的虹吸消除器进口相连通，虹吸消除器出口经器后排水管与市政排水窨井相连通。此外，本发明还提供了适用于人口密集地下室的紧急排水系统。本发明结构简单，设计科学合理，无论发生任何意外事件，包括止回阀被卡住，闸阀常开，甚至排水管突然破裂，室外的积水也不会倒灌入地下室，有效防止暴雨倒灌进入地下室，有巨大的社会和经济效益。
