摘要
不同的倒虹吸管布置型式,进口流态及淹没要求有所不同。对于斜管式进水口倒虹吸管,进口闸室流态类似于宽顶堰,其淹没要求是过闸水流淹没,而不必要求上游水面在进口管顶以上有多少淹没深度,在满足过闸水流淹没的条件下,上游水面可能高于管进口顶缘,也可能低于管进口顶缘。现就此观点进行研究和探讨,供商榷。
With different layout of inverted siphon pipe, requirements for inlet flow pattern and submergence are various. For oblique-pipe inlet inverted siphon pipe, flow pattern in intake chamber is similar to broad-crest weir. Its submerged requirement is overtopped lockage, thus submerged depth unnecessary for upstream surface over the top of inlet.
