Rainfall flood management system for permeable surface of sponge city and management method

Abstract

The invention discloses a rainfall flood management system for a permeable pavement of a sponge city and a management method. The rainfall flood management system comprises a meteorological bureau data sharing system, a weather station system, a sponge city permeable pavement rainwater pipe network system, a permeable pavement humidity collecting system and a central management system; the meteorological bureau data sharing system, the weather station system and the permeable surface humidity collecting system are all connected with the central management system; the problem of insufficient rainwater receiving capacity under the extreme rainfall weather can be effectively solved, a permeable pavement is connected with a urban rainwater pipe network system are connected through the sponge city permeable pavement rainwater pipe network system, and the excess rainwater is discharged to other rainwater management facilities in time through a drain valve, a flood drainage pump and a overflow valve.

Description

technical field [0001] The invention belongs to the technical field of urban drainage, and in particular relates to a rainwater management system and a management method for the permeable pavement of a sponge city. Background technique [0002] Studies have shown that the ground hardening rate in modern cities is high, and it takes a period of time for rainwater to enter the drainage outlet from the ground when a heavy rain occurs. If the surface runoff cannot be introduced into the urban rainwater pipe network or natural water body in time, waterlogging disasters may occur when a heavy rain occurs. Therefore, the exploration and construction of sponge cities has gradually begun on a global scale. Using the sponge city stormwater management system, the peak flow of rainstorms can be reduced through measures such as infiltration, retention, and storage, which is conducive to the control of urban waterlogging. At the same time, rainwater infiltration can also Supplement urban ...

AI Technical Summary

Problems solved by technology

[0004] (1) The design and construction of the permeable pavement is separated from the overall planning and construction of the sponge city, and there is a lack of monitoring feedback and comprehensive management of the permeable pavement during its service;

[0005] (2) There is a lack of effective assessment of the maximum rainfall and rainfall intensity that the permeable pavement can carry. In heavy rainfall weather, it is likely to cause rainwater overflow, and even affect the stability of the roadbed and affect driving safety.
