Abstract
A road network balanced drainage method aimed at reducing urban waterlogging is disclosed. According to the drainage demand, the existing intersection elevation is changed or the intersection elevation that meets the drainage requirement is designed and implemented in new construction so that the intersection drainage is distributed according to the desired proportion; the water flowing to the water accumulation position is transferred to reduce the waterlogging degree. Through the analysis of the depth of water accumulation in the whole road network, the method of water flow distribution at the intersection is used to make the precipitation flow evenly distributed in the whole road network. The method can be used for solving serious water accumulation of a certain road section, the balanced drainage of the whole road network, the technical transformation of existing intersections, and for the planned and designed roads. The method can effectively eliminate and prevent urban waterlogging.
