中小城市河道截污工程设计探讨

Discussion on Design of Small – Middle City River Waste Interception Engineering

随着城市化及旧城改造的进程,城中村等合流制地块会逐渐转变成分流制。对于流经分流制与合流制地块并存区域的河道,其截污管道与沿岸排污口的连接形式应根据地块的排水体制而有所不同,并且这种连接形式应既能合理地收纳现状合流制地块的污水,又便于将来向完全分流制形式过渡。该文介绍了此类截污主管道的形式,并提出了其设计计算及校核方法。

With the process of urbanization and old city reconstruction, the combined sewage system of Chengzhong Village and etc. will be gradually changed into the separation system. For the river simultaneously existing of separated system and combined system lands, the connection type of its waste interception pipes and the waste outlets along bank should be different based on the drainage system of the land. This connection type can not only reasonably accept the sewage from the present combined system land, is but also convenient for transition to the complete separation system in the future. The article introduces the main type of this waste interception pipe, and proposes its design calculation and check method.
