Study on Arrangement of Waterlogging Control Storage Tank in City Village

Abstract

In recent years, the problem of waterlogging in Chinese cities has become increasingly serious, and it is extremely urgent to solve the problem of waterlogging. Urban rainwater storage plays an important role in the prevention and control of waterlogging disasters. The control effect of the internal control of the storage tank is closely related to its layout position. On the basis of comprehensive consideration of the hydrological mechanism for reducing rainwater floods and the requirements for urban flood control, the Huangbian City Village of Panyu District, Guangzhou City was taken as an example to construct a one-dimensional, two-dimensional, pipe network coupled hydrological hydrodynamic model to study urban locusts and the optimal arrangement of the storage tank. The results show that compared with the centralized storage tank is arranged at the lower section of the pipe network bottleneck section and waterlogging point, arranging the storage tank in the upper section of the bottle neck section and the upstream of waterlogging point can not only significantly reduce the drainage pressure of the pipe network, reduce the flood area of waterlogging, but also reduce the storage capacity of a single storage tank and improve the feasibility of engineering construction. The arrangement method can effectively realize the storage function of the storage tank.
