The construction of this pumping station in the region can ensure the drainage and irrigation requirements of this area, and effectively promote industrial and agricultural production in the region.The pumping station is made up of two sets of 900ZLB-85-axial pump, the flow of drainage pumping stations designed for 4.6 m3/s, getting flooded and leaving flooded straightly,having the function pumping draining. The design can be summed up in four parts, Part I : crew choice patterns; Part II : overall layout; Part Ⅲ : stability calculation; Part Ⅵ : structure calculation. Pumping station consists of three components:the pump room, upstream and downstream connected parts etc. Pump room is composed by the lock bed, lock column, pumping stations, getting flooded pool, operating bridge; Upstream links includes three components: former pool ,upstream wing walls and upstream shore protection. Downstream links includes there components: out flooded pool, downstream wing walls,and downstream shore protection. The pumping station installs vertical axial pump and the type of pump room is wet-pit pump house with baffled wall. The type of the pumping station venue territories is Ⅲ. The foundation
