大口径穿堤原水管倒虹吸节能研究

Research on energy saving of inverted siphon of raw water pipeline with large caliber crossing dike

针对部分大型取水工程翻越河堤的原水管运行时有非满流现象、存在能耗浪费以及原水计量偏差问题,提出了采用单向排气阀倒虹吸设计方案。通过较少的投入,较好地解决了计量问题并取得了显著的节能效果,可为同类问题提供借鉴。

In view of the issues such as non-full flow,energy dissipation and raw water measurement error in the operation of raw water pipeline of some large water intake project when across a dike,a design scheme of inverted siphon with one-way exhaust valve was proposed. The measurement issue was well solved with less investment,remarkable energy saving effect was achieved,and it could provide reference for similar issues.
