Background
Due to unsmooth urban drainage, people are increasingly concerned about urban drainage due to the frequent urban sea-seeing phenomenon in recent years, and more cities have water shortage. The sponge city is a new generation of urban rainfall flood management concept, and means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can be called as a hydro-elastic city. The international generic term "low impact development rain water system construction". When raining, the utility model absorbs water, stores water, seeps water and purifies water, and when needed, the stored water is released and utilized.
Some water permeability terrace can be applicable to the less city of rainfall at present and use, but when the rainfall is great, the infiltration speed of rainwater is slow, can lead to a large amount of ponding, if the porosity that improves the terrace improves the infiltration speed of rainwater, then can make the intensity reduction of terrace, the life-span shortens.
