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.
