Sponge city road water storage and draining structure

Abstract

The invention discloses a sponge city road water storage and draining structure. The sponge city road water storage and draining structure comprises a sidewalk and a lane which are arranged along thewidth direction of a road and is characterized in that a green belt is arranged on the inner side of the sidewalk, and a plurality of rainwater inspection wells are arranged on the lane at intervals along the length direction of the road; the green belt sequentially comprises a water storage layer, a composite geomembrane, a planting soil layer, water-permeable geotechnical cloth, a middle sand layer and a grass planting tile layer from bottom to top; a water storage tank is embedded into the lane along the length direction of the road, the water storage tank comprises a tank body, the top endof the tank body is parallel with the surface of the lane, a long tank for storing water is arranged in the tank body, and a gap is arranged between the top of the long tank and the top surface of the tank body; the lane at the green belt is provided with a plurality water storage wells at intervals, and the water storage wells separate the water storage tank into multiple sections, a plurality of water-permeating pipes are connected to each storage water tank section at intervals, and the other ends of the water-permeating pipes extend into the water storage layer. The sponge city road waterstorage and draining structure has the advantages that the water storage tank is used to increase the water storage ability of the road, the water can be slowly released into the green belt after therain, watering frequency is reduced greatly, and draining pressure during heavy rains is relieved.

Description

technical field [0001] The invention relates to the technical field of urban construction, in particular to a road storage and drainage structure. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that cities have good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater, and can also be called "water elastic cities". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] To build a sponge city, it is necessary to develop corresponding water storage structures, water transfer structures and water release structures. Urban roads generally include sidewalks and roadways. Of course, roads such as vehicles can be divided into motor vehicle lanes and non-motor vehicle lanes. The current mainstream d...

AI Technical Summary

Problems solved by technology

At present, the water storage function of the green belt is limited. The areas of the green belt are separated by tree ponds and cannot be effectively connected. As a result, some areas have sufficient water and some areas need to be watered, which increases the frequency of watering and increases labor intensity.
