Background

Under the promotion of urbanization and industrialization, the material conditions and economic level of China have qualitative leaps, but the urban inland inundation, the rainwater runoff pollution, the ecological environment deterioration and other environmental problems are faced for a long time in the rapid but unhealthy urbanization process. Therefore, an environmental protection measure which can realize the storage, permeation and purification of rainwater in urban areas and ensure the safety of urban drainage and waterlogging prevention is urgently needed. In order to improve the utilization rate of rainwater resources and perfect the ecological environment protection mechanism, the design concept of the sponge city is developed.

With the rapid advance of urbanization, the built-up area of cities in China is continuously enlarged, the quantity of the cities is continuously increased, and meanwhile, the cities face a severe rainwater problem: on one hand, the underground water level of the city is continuously reduced, water resources become more and more scarce, and on the other hand, flood disasters frequently occur. Therefore, how to fully utilize rainwater resources will become an important target for urban ecological construction in the future.

The dilemma of water drainage and storage in modern cities in China mainly includes the following aspects: (1) draining water; china is a continental monsoon climate, cities are frequently attacked by heavy rainstorms every summer, and after the heavy rainstorms, all cities have serious water accumulation; the main reasons for water accumulation are that the urban drainage pipe network in China is insufficient in capacity and impervious in road surface, and a large amount of surface runoff can be generated in a short time after rain. (2) Water storage dilemma; in the process of building many cities, the closure of the earth surface is caused by a large amount of adopted asphalt concrete, and the obvious adverse effects are generated on the ecological and climatic environments of the cities; modern urban ground surfaces are difficult to find soil, water is difficult to seep downwards, rainwater is directly discharged to a river channel, plants on the ground surfaces are difficult to grow, and some trees even die due to water shortage of root systems. Domestic and industrial water in a large number of cities, particularly northern cities, still takes underground water as a main part, the underground water supply path is blocked, and the urban underground water has no chance to recover after being pumped, thereby causing the problem of ground settlement.

In view of the above problems, it is necessary to improve them.
