Novel water-permeation road and construction method thereof

Abstract

The invention relates to a novel water-permeation road. The novel water-permeation road comprises a road pavement layer, a water-permeation base layer, a subgrade and catchpits, wherein the road pavement layer, the water-permeation base layer and the subgrade are sequentially arranged from top to bottom; the catchpits are respectively arranged at both sides of each of the road pavement layer, thewater-permeation base layer and the subgrade; the two sides of the water-permeation base layer are respectively connected with the catchpits through first water-permeation interfaces; a water drainagepipe is arranged in each catchpit; a second water-permeation interface is arranged at the bottom part of each catchpit. The novel water-permeation road has the advantages that the water seepage and water storage functions are realized, and the risk of waterlogging in city is effectively decreased.

Description

technical field [0001] The invention relates to the technical field of urban road construction, in particular to a novel permeable road and a construction method thereof. Background technique [0002] At present, most of the urban roads in our country are asphalt pavement or cement pavement. Although these two roads have good strength, their water permeability is poor, and rainwater cannot penetrate into the ground. , When the weather is fine, under the sunlight, the road surface will emit a lot of heat, resulting in the "heat island phenomenon". When the rainfall is heavy, the rainwater cannot penetrate, and the existing road drainage facilities are difficult to cope with, so urban waterlogging often occurs. [0003] In order to solve the above-mentioned road defects of poor water permeability, permeable roads have appeared in the prior art, allowing rainwater to penetrate into the interior of the pavement structure, but it has brought another problem: the water inside the...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the urban roads in our country are asphalt pavement or cement pavement. Although these two roads have good strength, their water permeability is poor, and rainwater cannot penetrate into the ground. , when the weather is fine, under the sunlight, the road surface will emit a lot of heat, resulting in the "heat island phenomenon"

When the rainfall is heavy, the rainwater cannot penetrate, and the existing road drainage facilities are difficult to cope with, so urban waterlogging often occurs

[0003] In order to solve the above-mentioned road defects of poor water permeability, permeable roads have appeared in the prior art, so that rainwater can penetrate into the interior of the pavement structure, but it has brought another problem: the water inside the road cannot be discharged, resulting in water damage to the road surface

Although the drainage pavement can solve this problem, the drainage pavement only plays the role of drainage, but cannot fully play the role of water seepage and water storage in the structural layer of the permeable road.
