Road rainwater collecting and utilizing device

The utility model relates to a road rainwater collecting and utilizing device belonging to the field of road engineering. The rainwater collecting and utilizing device mainly comprises a permeable curb, a runner and a water storage layer. The device is arranged at a street tree position of a sidewalk, the permeable curb is arranged at the position of a road curb, which corresponds to a street tree pit position, the water storage layer is arranged at the periphery of the tree pit, and the permeable curb and the water storage layer are communicated through the runner. The rainwater flows to a road side along a longitudinal slope and a cross slope of a road, and passes through the permeable curb to flow towards the water storage layer through the runner, in the way, the rainwater can slowly permeate into the tree pit and the underground so as to irrigate trees and supplement underground water. The road rainwater collecting and utilizing device has the advantages that the structure is simple, the construction is convenient, the cost is low, the materials are easy to get, the functions and the appearance of the road can not be affected, water for irrigation is saved, and the economic benefit and social environment-friendly benefit are better.
