The Design And Reseach In Major Problem Of Head Sluice In Tianjin Main Route Of South-to-north Water Diversion Project

The South-to-North Water Diversion is a superproject which resolve industrial and agricultural water where Hebei,Henan,Tianjin,Beijing several provinces, Tianjin Main Route Project is a portion of it. The head sluice of Tianjin Main Route is the first sluice in it,which is important construction connect Tianjin Main Route to South-to-North Water Diversion.In this paper,some basic ways and steps in design of sulice are introduced at fast,such as collecting basis,disposing of junction,hydraulic calculation and structure analysis.Then the design of head sluice in Tianjin Main Route of South-to-North Water Diversion is recommended,which is not only distribution gate,but also is one and only regulated flow sluice of Tianjin Main Route Project. Besides disposing of junction,hydraulic calculation and structure analysis, some practical problems are particular introduced in the process of design,such as confirmming scale and size,structure calculation in finite-element method,draining ice,foundation treatment etc. The writer put forward his own viewpoints to us by resolving these practicality problems.We can learn basic knowledge and ways of sluice design,but it provide project experience from this paper.
