Background

In recent years, rain flood control and rain water utilization have received increasing attention in municipal drainage planning and building design. In order to achieve the purpose of rainwater utilization while completing rainfall flood control, natural lakes are often utilized in engineering construction, or rainwater regulation facilities such as a rainwater regulation pool and a rainwater bucket are manually arranged, and a part of rainwater is reserved for later recycling; meanwhile, the existing rainwater storage and regulation facilities are generally scheduled in real time by means of empirical analysis of engineering designers, and a scientific and reliable scheduling operation method is lacked. Under the background, the space of the rainwater storage facility is often filled in the early stage of rainfall, the storage capacity is difficult to be fully utilized, the relief effect on urban waterlogging is very limited, and the drainage capacity of a rainwater pipe network is not fully utilized; in addition, the initial rainfall is generally high in pollutant content, and the storage water pollutant content is also increased sharply by collecting and storing the initial rainfall runoff. When the rainfall intensity in the rainfall process develops to the maximum, the regulation and storage facility usually stores the full water and quits the work, which is exactly the key period of the occurrence of the waterlogging, after the rainfall exceeds the drainage capacity of the drainage system, a large amount of rainwater can not enter the regulation and storage facility to be absorbed, the rainwater can be accumulated on the ground surface to cause the serious waterlogging, and the regulated and stored rainwater can reduce the drainage pressure of the municipal rainwater and reduce the runoff flood peak.
