Water penetration pavement structure in sponge city

Abstract

The invention discloses a water penetration pavement structure in a sponge city. The water penetration pavement structure comprises an upper plate, a lower plate and a supporting structure arranged between the upper plate and the lower plate for supporting the upper plate, wherein the upper plate and the lower plate are separated through the supporting structure to form a hydrophobic space; the supporting structure comprises a supporting block and penetration blocks; the upper end of the supporting block abuts against the lower surface of the upper plate; the lower end of the supporting blockabuts against the upper surface of the lower plate; each penetration block comprises water release parts and water penetration parts; installation sites for installing the water release parts are formed at the supporting block; and the water release parts are exposed to the interior of the hydrophobic space. The upper plate is made of a concrete material, and the structure of the whole body can beof greater bearing capacity through the supporting of the supporting structure; and moreover, second openings are formed in the upper plate, gathered water on a pavement can be discharged through thewater penetration parts inside the openings and permeates the hydrophobic space within a certain period of time, groundwater resources are supplemented, and an urban heat island effect is relieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water seepage pavement structure for a sponge city. Background technique [0002] The surface of modern cities has been gradually covered by water-blocking materials such as buildings and concrete, thus forming an ecological "artificial desert". Impervious concrete and asphalt are the main pavement materials in the city, so that the rainwater that falls naturally cannot penetrate into the ground naturally and smoothly; this is the main reason for the lack of ability to adjust the temperature and humidity of the urban surface, resulting in the so-called urban The "heat island effect" may cause waterlogging in the city during the rainy season. In order to alleviate the damage to the environment and fundamentally manage the stable ecological environment of the city, the central government has recently put forward the new concept of building a "sponge city". "Sponge ci...

AI Technical Summary

Problems solved by technology

[0003] The construction of a sponge city requires a lot of seepage bricks for simple laying of roadsides and road surfaces. In the event of natural disasters such as waterlogging, the drainage speed below the ground cannot keep up with the water seepage speed, and the water seepage capacity is still poor, and it is easy to block. Moreover, according to relevant experience and research, after a period of use, the strength of seepage bricks will decrease significantly, which will cause a large area of ​​brick surface to be broken, resulting in damage to the road surface, which cannot meet the requirements of sponge city construction.
