目前钢筋混凝土倒虹吸管的设计,其管身截面都是采用厚壁圆筒结构,是属小偏心受拉又不允许出现裂缝的水工建筑物。在工程布置上大体是外露和沟埋两种形式,外露式基础开挖处理简易,土石方量少,管身不复盖土,可大大地节省复盖土石方量。 At present, the design of inverted siphon reinforced concrete, the body section is the use of thick-walled cylinder structure, is a small eccentric tension and does not allow cracks in hydraulic structures. In the layout of the project is generally exposed and ditch buried in two forms, exposed foundation excavation simple, less earth and stone, the body does not cover the soil, can greatly save the amount of cover earthwork.
