Sponge city permeable road brick

Abstract

The invention discloses a sponge city permeable road brick. The sponge city permeable road brick comprises a brick body of a square structure without a top. A flat-plate-shaped permeable layer is fixedly arranged above the brick body in a covering manner. A plurality of capillary ropes are fixedly embedded in the inner bottom of the brick body and the lower bottom of the permeable layer. A gear isfixed to each capillary rope. The multiple gears are jointly engaged with one rack. The lower wall of the permeable layer is fixedly connected with an air pipe sealed on one side. The interior of theair pipe is in sealed sliding connection with a piston. The sponge city permeable road brick has the advantages that the ground surface temperature is increased, the air pipe is heated and expanded to push the piston to move, the rack drives the gears to rotate, the winding degree of the capillary ropes is high, the distance between filaments in hemp ropes is small, the capillary effect is obviously improved, water stored in the brick body can be conveyed into the permeable layer trough the capillary ropes under the effect of the capillary function, a certain evaporation amount is guaranteedat the position of the permeable layer, the ground surface temperature is reduced, and generation of a heat island effect is avoided.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a brick for permeable roads in sponge cities. Background technique [0002] In contemporary metropolises, the urban ground is mainly paved with cement or asphalt, which has led to the urban heat island effect becoming more and more obvious in recent years. The sponge city advocated in modern society is to promote the construction of green buildings, the development of low-carbon cities, and the formation of smart cities. The performance of innovation is the organic combination of modern green new technologies and various factors such as society, environment, and humanities under the background of the characteristics of the new era. [0003] Most of the traditional pavement permeable bricks for sponge city construction are simple in structure and can only play a role in water permeability, and their water storage effect is very limited, and they cannot be adjusted to switch ...

AI Technical Summary

Problems solved by technology

[0003] Most of the traditional pavement permeable bricks for sponge city construction are simple in structure and can only play a role in water permeability, and their water storage effect is very limited, and they cannot be adjusted to switch between water storage and drainage states according to the amount of rainfall, and the utilization rate of rainwater is low. ;More permeable bricks can only store a small amount of water through the pores of their own materials. In hotter weather, after the evaporation in the permeable bricks is completed, there is no difference between ordinary floor tiles, which makes it difficult for water to evaporate, and improves the urban heat island effect. poor
