Sponge type rainwater permeation collection and drainage system

Abstract

The invention provides a sponge type rainwater permeation collection and drainage system. A sponge and a sponge principle are applied, the reduction capacity of underground gravel and soil on water is utilized, and the problem of poor water drainage capacity of an existing water drainage system is mainly solved. The sponge type rainwater permeation collection and drainage system comprises a water drainage pipe, a water-permeable isolation layer, a gravel permeation layer, a sandy soil permeation layer, a ground permeation layer, a rainwater direct drainage pipe, a water drainage rain grate and a desilting basin. The water-permeable isolation layer surrounds the outer side of the water drainage pipe. The gravel permeation layer surrounds the outer side of the water-permeable isolation layer. The sandy soil permeation layer surrounds the outer side of the gravel permeation layer and is located below the ground permeation layer. The water drainage pipe communicates with the desilting basin and is provided with water drainage holes. The manner of combining permeation and direct drainage is adopted, rainwater permeates the road surface to enter the underground water drainage pipe and is drained and conveyed by the water drainage pipe and locally absorbed by the underground soil and gravel and the like, the aim of fast reducing accumulated water on the road surface is achieved, rainwater depositing is not prone to being caused, and the water drainage capacity of an urban water drainage system is improved.

Description

technical field [0001] The invention relates to a city or urban rainwater drainage system, in particular to a sponge type rainwater infiltration collection and drainage system. Background technique [0002] In the process of urban development, a large amount of land has been hardened, the ecology is out of balance, coupled with insufficient rainwater drainage facilities, small capacity, unreasonable layout, and insufficient innovative means, etc., resulting in prominent urban waterlogging, endangering the safety of people's lives and property, and damaging urban development. image. In addition, the existing drainage system basically uses pipes for drainage. When the water flow is too fast, the drainage capacity of the pipes is limited, which may easily cause urban waterlogging.
