In recent years, some urban flood disasters have caused large-scale casualties, making relevant government departments more aware of the seriousness of the problem. On the basis of absorbing the urban development concepts and development achievements of relevant countries, the Ministry of Housing and Urban-Rural Development of my country issued the "Technical Guidelines for Sponge City Construction-Low Impact Development System Construction" in 2015, which identified sponge city construction as the core of urban construction in my country Major strategic guidelines can be summarized as follows: follow the principles of ecological priority, combine natural and artificial methods, and maximize the accumulation, infiltration and purification of rainwater in urban areas on the premise of ensuring the safety of urban drainage and waterlogging. Promote the use of rainwater resources and ecological environment protection. For the storage of rainwater resources, it is necessary to build a comprehensive and diversified rainwater storage system on the ground and underground. Traditionally, the above-ground water storage system is mainly to reserve enough surface water conservation land for the city - rivers, rivers, lakes, pools, ditches, canals, wetlands, etc., these urban waterways, natural and artificial water bodies and other blue belts and green corridors The ecological framework integrated with green belts such as roads and wedge-shaped green belts is an important basis for building an ecological barrier for urban water security. However, in order to prevent and control urban rainwater hazards to the greatest extent, it is necessary to start from the source and build on-site rainwater collection and storage facilities.

After the water level in the rainwater buffer rises to close to the outlet pipeline 2 When the height is higher, the gravity self-closing valve on the outlet water pipe one resets and closes, and the rainwater storage device receives relatively clean middle and late rainwater and then enters the rainwater storage device through the outlet pipe two. If there is enough rainwater, the water level of the rainwater storage will continue to rise. When the water level reaches the overflow pipe level, the excess water will be discharged into the sunken green space or underground rainwater pipe through the overflow pipe, and the solenoid valve on the discharge pipe will be opened at the same time. The initial rainwater stored in the rainwater buffer is drained, and the excess rainwater can be discharged directly through the rainwater buffer through the outlet pipeline.

The solenoid valve of the rainwater buffer drains the initial rainwater stored in the rainwater buffer, and then resets the solenoid valve. The integrated rainwater collection device can be cleaned regularly and simply according to the quality of rainwater, and the cleaning water is discharged through the vent pipe.
