Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Such as figure 1 , 2 As shown, a sponge city permeable pavement of the present invention comprises a pavement body and drainage ditches 15 arranged on both sides of the pavement body. Subgrade 13 and compacted subgrade 14, permeable asphalt concrete layer 11 adopts asphalt pavement with OGFC layer laid, permeable subgrade 12 is formed by splicing several permeable subgrade prefabricated blocks 121, leaving a gap between two adjacent permeable subgrade ...

Abstract

The invention discloses a porous pavement for a sponge city, comprising a pavement body and draining ditches at both sides of the pavement body; the pavement body includes a permeable asphalt concrete layer, a permeable roadbed layer, a water-retained roadbed layer and a tamping roadbed layer which are arranged orderly from top to bottom; the permeable roadbed layer is formed by splicing several permeable roadbed prefabricating blocks, a joint is reserved between adjacent permeable roadbed prefabricating blocks; permeable grooves are arranged on the upper surface and the side wall of every permeable roadbed prefabricating block. The porous pavement for the sponge city can make much rain permeate in rainstorm comes, so ass to effectively prevent the urban inland inundation; for a light rain, much rain can return to an urban underground water circulation system; moreover, air humidity can be added when the weather is dry and hot, so as to adjust urban temperature and humidity; moreover, massive building waste recycled aggregates are applied; therefore, porous pavement is advantageous of economy and environment-friendly.

Description

technical field [0001] The invention relates to a road, railway or bridge construction, in particular to a road pavement. Background technique [0002] With the acceleration of China's urbanization process, not only heavy rains often cause serious urban waterlogging, but also rainwater cannot enter the urban groundwater circulation system well during small amounts of precipitation. The road system has poor water absorption and drainage capacity. At present, my country's solutions to the above problems mainly include increasing the diameter of drainage pipes, online water storage, and building reservoirs, etc., but these measures not only generally have many disadvantages such as large investment and large space occupation, but also long construction time and low efficiency. . Contents of the invention [0003] The purpose of the present invention is to provide a sponge city permeable pavement to solve the above-mentioned problems in the prior art. It can not only allow a ...
