Road surface rainwater side drainage and permeation structure and construction method

Abstract

The invention discloses a road surface rainwater side drainage and permeation structure and a construction method. The structure comprises a percolation ditch formed by recessing a roadbed basal plane, wherein curb curbstone is vertically arranged on the roadbed basal plane on at least one side of the percolation ditch in a supporting mode, the curb curbstone extends in the length direction of theroadbed, and a space formed by the percolation ditch and the curb curbstone is filled with a percolation layer used for percolating rainwater. A plurality of drainage through holes are formed in thecurb curbstone, the drainage through holes are sequentially distributed in the length direction of the curb curbstone at intervals, the water inlet end of each drainage through hole is communicated with the road surface of a road layer laid on the roadbed basal plane, and the drainage ends of the drainage through holes are communicated with the percolation layer so as to enable rainwater on the road surface to seep into the percolation layer. According to the road surface rainwater side drainage and permeation structure, when rainwater is drained through the plurality of drainage through holes, the drainage rate can be increased, the scouring force of drainage on the roadbed and a green belt soil body is reduced at the same time, and scouring water damage to the roadbed and the green beltdue to too large rainfall is avoided.

Description

technical field [0001] The invention relates to the field of side drainage of road surface rainwater, in particular to a permeable structure for side drainage of road surface rainwater. In addition, the present invention also relates to a construction method for constructing the above-mentioned rainwater side drainage permeable structure on the pavement. Background technique [0002] At present, the country vigorously advocates the construction of sponge cities. During the construction of the Buban Connecting Road Project in Longgang District, Shenzhen, which is undertaken by our company, the road is set on the road curbs to infiltrate rainwater into the subgrade soil according to the requirements of the sponge city construction in Shenzhen. The water inlet (rainwater collection port) of the body and the green belt soil. However, due to the long construction time span of the project, during the construction process, it was found that the water flow at the inlet of the rainw...
