A Design and Analysis Method of Urban Waterlogging Removal System

Abstract

The invention relates to a design analysis method of an urban inland inundation drainage system. The method comprises the following steps: determination of a computational domain and a control equation; basic document and relevant parameter setting; inland inundation water accumulation point analysis; design of a water drainage source item; design of inland inundation calculation of a scheme; optimization of the water drainage source item; optimization of the inland inundation calculation of the scheme; judgment; and determination of an inland inundation drainage scheme. According to the method, the inland inundation drainage system is optimized in design, the size of the system is simplified to be equal to that of the water drainage source item, and the position is optimized; the arrangement of a rainwater hole and a water pump is determined according to the water drainage source item so as to realize that supply is determined by requirement, which is a great improvement on setting out an inland inundation drainage scheme and then performing inland inundation drainage safety analysis and optimization in the past, technical guidance and solution are provided for design, analysis and optimization of the inland inundation drainage system, and the inland inundation safety on an urban road is guaranteed.

Description

technical field

[0001] The invention relates to a design and analysis method for an urban waterlogging removal system, which is a hydrological calculation method and a method for analyzing and calculating an urban drainage system. Background technique

[0002] As the global climate changes, extreme weather increases, and urban rainstorms increase in frequency and intensity. On the other hand, the development of urbanization has resulted in hardened road surfaces, more buildings, and reduced green areas and permeable areas. Therefore, the city's ability to store rainfall has weakened, and the runoff duration has shortened and its intensity has increased. Therefore, the problem of urban waterlogging caused by heavy rainfall and low drainage capacity is becoming more and more obvious, which can easily cause urban traffic jams, short-term social chaos, and even cause public health safety problems. Therefore, urban drainage is an important part of urban construction and developme...
