Road rainwater collecting system

Abstract

The invention provides a road rainwater collecting system comprising a pavement (1), a green belt (2) and a water filtering ditch (3). A curb (4) is arranged on the edge of the pavement. Drainage holes (5) are formed in the side wall of the curb. The green belt comprises a macadam layer (21) and a planting soil layer (22) laid on the macadam layer. The water filtering ditch is arranged between the pavement and the green belt and comprises a bottom wall (31) provided with an anti-seepage structure, and two side walls (32); water inlets (6) communicating with the drainage holes are formed in one of the side walls (32), and first water outlets (7) communicating with the macadam layer are formed in the other side wall (32), wherein the positions of the water inlets are higher than that of the first water outlets. The road rainwater collecting system can recycle rainwater, meanwhile, the collected rainwater can be absorbed by a soil plant vegetation layer for assisting growth of plants of flowers, trees and the like, and the problem of water accumulating of the pavement in a residential district can be effectively solved.

Description

technical field [0001] The invention relates to the field of road rainwater collection, in particular to a road rainwater collection system. Background technique [0002] At present, the water permeability of the road surface in modern residential quarters is relatively low. When the environment is relatively harsh, a large amount of rainwater can only be discharged into the river through the drainage facilities, which greatly increases the burden on the drainage facilities, so a large amount of water will form on the road. , which adversely affects the comfort and safety of pedestrians. On the other hand, the amount of water infiltrated into the ground by roads with poor water permeability will gradually decrease, resulting in a decrease in the groundwater level. Industrial production and modern life have doubled the amount of groundwater extraction, causing insufficient water in the soil, Problems such as lack of oxygen and rising ground temperature directly affect the he...

Problems solved by technology

[0002] At present, the water permeability of the road surface in modern residential quarters is relatively low. When the environment is relatively harsh, a large amount of rainwater can only be discharged into the river through the drainage facilities, which greatly increases the burden on the drainage facilities, so a large amount of water will form on the road. , adversely affect the comfort and safety of pedestrian traffic

On the other hand, the amount of water infiltrated into the ground by roads with poor water permeability will gradually decrease, resulting in a decrease in the groundwater level. Industrial production and modern life have doubled the amount of groundwater extraction, causing insufficient water in the soil, Problems such as lack of oxygen and rising ground temperature directly affect the health of urban vegetation and further aggravate urban drought and water shortage.
