At present, single-stage water drops in cities do not have the function of regulation and storage, and when the size and the shape of a boundary are not suitable enough, the torrent flow state of the water drop discharge is deteriorated, so that the scouring of a channel embankment is aggravated. And the conventional drop only carries out energy dissipation treatment on water flow at the drop position, and cannot further purify the water quality. When a large rain condition occurs, the large upstream water flow can cause great scouring to the sloping fields on the two sides of the channel, so that serious water and soil loss can be formed in the past, and the danger of forming debris flow can be formed at all times. Simultaneously, the rainwater of municipal facilities such as roads on both sides of the channel also can naturally flow to the channel, and the rainwater which is not purified has more solid pollutants such as silt, garbage and the like and soluble pollutants, thereby polluting the water body and the whole ecosystem.
In order to solve the problems of serious urban water body pollution, low rainwater utilization rate and the like, the concept of a sponge city is provided and applied. The core theory of sponge city is "ooze, stagnate, hold, clean, use, arrange" six words, is about to the utilization that the rainwater passes through the sponge facility, reaches to make it fully absorbed and purify by vegetation and soil, can utilize the rainwater to nourish the vegetation in the road both sides greenbelt when accomplishing to reduce the rainfall volume, also reaches the effect of utilizing purification rainwater such as vegetation and soil. Therefore, the burden of the original urban drainage system can be reduced, and the water storage and purification capacity of the city can be exerted to the maximum extent.
