[Abstract]:When the water level of the receiving water is higher than the top elevation of the outlet of the Rain Water pipeline, the Rain Water cannot be discharged by gravity self-flow, or the surface elevation of the drainage area is lower than the maximum water level of the receiving water. The 2014 edition of the Outdoor drainage Design Code puts forward that the drainage design needs to consider the recurrence period of the waterlogging prevention and control, but the current calculation method of the scale of the Rain Water pumping station is insufficient. The calculated Rain Water pumping station size needs further optimization. According to the specification, the paper discusses the optimization of pumping station scale by using rain flood model. The main work is as follows: based on the conventional method, the simplified Rain Water model method is selected to optimize the scale of Rain Water pumping station. The scale of Rain Water pumping station with and without storage facilities is calculated by using different model methods, and the calculation scale of three model methods is optimized by AHP, and the optimal scale of final Rain Water pumping station is determined. The effects of storage and storage facilities and water level on the scale and operation of pumping stations are discussed. The conclusions are as follows: (1) the conventional method, simplified SCS model method and InfoICM model software method have their own advantages in practical application, and the calculated pumping station scale is reasonable, but the three methods have some shortcomings. After comprehensive consideration, the optimal size of pumping station should be obtained; (2) the final size of Dongsi pump station is determined to be 35 m3 / s, and the final scale of Yanglan Lake pumping station is determined to be 77.9 m3 / s after the calculation of analytic hierarchy process (AHP) method; (3) the regulating and storing facilities can effectively reduce the size of pumping station. Therefore, attention should be paid to the protection and restoration of lake waters, in addition, the ability of Rain Water pumping station to cope with heavy rain can be improved by lowering the water level of the pump, and it is suggested that the water level of the pump should be lowered properly before the rainfall to reduce the risk of flood disaster.
