低洼住宅小区排水系统的改造设计

Reconstruction Design of Drainage System in Low-lying Residential Areas

在某沿海城市低洼住宅小区的改造设计中,对其雨水、污水排水系统进行了综合改造。设计中以"挡水为主、排水为辅,自排为主、强排为辅"为原则,将自流排水与强制排水相结合,保证了排水的安全性与经济性,并优化了水泵启动方式及泵站施工工艺。

In the reconstruction design of a low-lying residential area of a coastal city, its rainwater and sewage drainage systems were reconstructed. Based on mainly damming water accompanied by water drainage, mainly gravity flow accompanied by pumping drainage, the combination of gravity flow with pumping drainage ensured the safety and economical efficiency of drainage, and optimized the pump startup mode and the construction technology of pumping station.
