Urban road green belt and sidewalk rainwater drainage system and construction method

Abstract

The invention discloses an urban road green belt and sidewalk rainwater drainage system and a construction method and relates to the technical field of urban construction. The system comprises a motorvehicle lane, a green belt, a non-motor vehicle lane and a sidewalk. A surface of one side of the green belt is connected with the motor vehicle lane through a first vertical kerb; the other side isconnected with one side of the non-motor vehicle lane through a second vertical kerb; the other side of the non-motor vehicle lane is connected with the sidewalk through a third vertical kerb; rainwater wells are arranged at the bottoms of one sides of the motor vehicle lanes and the non-motor vehicle lanes; and an overflow rainwater well is arranged at the bottom of one side of the green belt, the rainwater well and the overflow rainwater well are connected with a municipal rainwater pipe, water permeable bricks are laid on the surface of the sidewalk, the green belt is sequentially providedwith an anti-seepage composite geomembrane, a gravel layer, water permeable geotextile and planting soil from bottom to surface, and a water permeable pipe wrapped with the water permeable geotextileis connected with the overflow rainwater well. The system and the method are used for urban road and cell and factory road construction, can effectively solve problems of urban waterlogging and unsmooth drainage, and has characteristics of wide application, strong practicability, firmness and durability, and simple and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of urban road construction, in particular to an urban road green belt, sidewalk rainwater drainage system and a construction method. Background technique [0002] At present, in the process of urban road construction, excessive development and disorderly construction occur from time to time. After a large number of urban road surfaces are hardened, the original hydrological characteristics of the road are destroyed, resulting in the absorption, storage and slow release of rainwater on urban roads. The effect is reduced. Once it enters the rainy season, whether it is sidewalks or green belts, rainwater cannot be discharged in time, resulting in a large amount of water on the road surface, slippery sidewalks, unsafe pedestrians, waterlogging in green belts, and rainwater leakage from green belts pollutes the road surface, which increases urban waterlogging and pollution during the rainy season. Urban runoff p...

[0002] At present, in the process of urban road construction, excessive development and disorderly construction occur from time to time. After a large number of urban road surfaces are hardened, the original hydrological characteristics of the road are destroyed, resulting in the absorption, storage and slow release of rainwater on urban roads. Reduced effect

Once it enters the rainy season, whether it is sidewalks or green belts, rainwater cannot be discharged in time, resulting in a large amount of water on the road surface, slippery sidewalks, unsafe pedestrians, waterlogging in green belts, and rainwater leakage from green belts pollutes the road surface, which increases urban waterlogging and pollution during the rainy season. Urban runoff pollution loads cause potential safety hazards to vehicle driving and pedestrian safety. This phenomenon does not conform to the advanced concept of modern sponge city construction
