Construction method of porous pavement

Abstract

The invention discloses a construction method of a porous pavement. The problems that in the flood season, a basic pavement layer of a porous pavement in the prior art is likely to be soaked softly byaccumulated water, strength is reduced, and an upper porous brick layer settles are solved. The method is technically characterized in that the method includes the steps that a roadside ditch is excavated, wherein an excavator is used for excavating the roadside ditch for containing a pavement layer; a leveling basic layer is built, the bottom face of the roadside ditch is trimmed, so that the bottom face is level, the bottom face of the roadside ditch is compacted through a road roller and paved with graded broken stone, and the upper surface of the graded broken stone is level; a basic pavement layer is built on the leveling basic layer, supporting bodies are arranged at intervals, and filling spaces used for filling porous base bodies are formed between the supporting bodies; the filling spaces are filled with the porous base bodies, and a supporting face used for supporting a porous face layer is formed by the porous base bodies and the upper ends of the supporting bodies; the porous face layer is built on the basic pavement layer; and a road is maintained. The method has the beneficial effects that the strength of the pavement is improved, and a pavement settlement phenomenonis reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, more specifically, it relates to a construction method of a permeable road surface. Background technique [0002] At present, when building sidewalks, squares and other public open-air places in cities, in order to solve the problems of rainy days and poor drainage, permeable bricks are often laid on ordinary concrete as the permeable pavement of these open-air places. [0003] For example, Chinese invention patent, application number is 201710186262.5, discloses a kind of permeable pavement, the main point of its technical scheme is: comprise leveling base layer, basic pavement layer and permeable brick layer arranged in sequence from bottom to top, described basic pavement layer is made of A number of permeable base bricks are laid in sequence; the permeable brick layer is formed by laying a number of permeable bricks; water collecting tanks are pre-buried along the length direction o...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technology uses the base pavement layer to carry the permeable brick layer. Since the base pavement layer has a water-permeable function, it is relatively soft. When encountering a flood season, the water accumulated in the base pavement layer has no time to discharge, making the base pavement layer further softened. Its strength is reduced, and it is easy to cause the settlement of the upper permeable brick layer
