Water regulating and storage structure for road between green belts

Abstract

The invention discloses a water regulating and storage structure for a road between green belts. The water regulating and storage structure comprises the road between the green belts, a curb is arranged at the junction of the road and the green belts, and a drain sink is arranged on the position, close to the curb, of the road; a pervious concrete layer is arranged at the bottom of the curb, the curb and the pervious concrete layer serve as the side walls of the drain sink, a gravel layer is arranged on the lower part of a soil layer of the green belts, the edge of the gravel layer is locatedon the lower part of the pervious concrete layer, a first water storage tank is arranged on the lower part of the gravel layer, a second water storage tank is arranged on the lower part of the first water storage tank, a communicating pipe communicating with the second water storage tank is arranged on the upper part of the first water storage tank, a plurality of water absorbing pipelines are arranged between the first water storage tank and the soil layer of the green belt, and the second water storage tank is provided with a drainage pipeline. According to the water regulating and storage structure, rainwater of the green belt and the road can be effectively drained in time, the situation that plants are soaked by the rainwater for a long term is avoided, stored water can further be fedback to the plants during drought, and the rainwater is filtered and purified.

Description

technical field [0001] The invention relates to a water regulation and storage structure, in particular to a water regulation and storage structure for green belts and roads between them. Background technique [0002] At present, the urban green belts and the roads between them mainly discharge rainwater through drainage pipe ditches. These drainage pipe ditches are scattered on the surface in dots. Moreover, for heavy rainfall, there is a lot of rainwater accumulated in the green belt, and the plants are soaked in rainwater for a long time, which affects the healthy growth of plants and causes waterlogging damage, and the rainwater cannot be effectively stored for use in times of drought. During drainage, rainwater and surface dirt are collected together, affecting post-processing purification. In order to solve the above problems, it is necessary to effectively transform the existing green belt water storage structure. Contents of the invention [0003] The object of t...

Problems solved by technology

[0002] At present, the urban green belts and the roads between them mainly discharge rainwater through drainage pipe ditches. These drainage pipe ditches are scattered on the surface in dots.

Moreover, for heavy rainfall, there is a lot of rainwater accumulated in the green belt, and the plants are soaked in rainwater for a long time, which affects the healthy growth of plants and causes waterlogging damage, and the rainwater cannot be effectively stored, and it will be used in case of drought.

During drainage, rainwater and surface dirt are collected together, affecting post-processing purification
