倒虹吸和泵站在跨河污水管中的应用

Application of inverted siphon and pumping station in sewage pipe crossing river

和政县滨河东区文旅综合体配套市政污水管需跨越广通河,无法按原定高程通过。为满足近远期结合的需求,该项目采用了泵站和倒虹吸管两种措施实现管道跨河。阐述了两种措施在该项目中的可行性,并针对设计参数进行了水力计算,确保设计参数的合理性,并根据计算结果提出了优化措施。

The sewage pipe supporting the cultural tourism complex in East Binhe district of Hezheng county needs to cross the Guangtong river and cannot pass at the original elevation.In order to meet the needs in the near and long term,the sewage pipe crosses the river in two ways in the project:pump station and inverted siphon.This paper expounds the feasibility of the two measures and conducts hydraulic calculation for the design parameters to ensure the rationality of the design parameters,and proposes optimization measures according to the calculation results.
