Shallow water storage pavement water permeable brick

Abstract

The invention discloses a shallow water storage pavement water permeable brick including an upper water permeable brick, a broken stone cushion layer, a graded gravel layer, a geotechnical waterprooflayer and a base layer; the base layer is compounded with the geotechnical waterproof layer; the geotechnical waterproof layer is compounded with the graded gravel layer; the graded gravel layer is compounded with the broken stone cushion layer; the broken stone cushion layer is compounded with the upper water permeable brick. By the way, the invention provides the shallow water storage pavement water permeable brick; the shallow water storage pavement water permeable brick has the characteristics of simple construction, convenient maintenance, strong downward infiltration capacity and the like, effectively achieves water storage and ventilation functions, greatly alleviates the problems of city internal waterlogging and heat island effect, has the advantages of simple structure and convenient maintenance, and is especially suitable for reconstruction of sidewalks, squares, green belt edges and other newly built hardened pavements and conventional hardened pavements.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a permeable brick for shallow water storage pavement. Background technique [0002] The existing permeable bricks can be divided into permeable brick pavement, permeable cement concrete pavement, permeable asphalt concrete pavement, grass-embedded brick and cobblestone and gravel pavement in garden pavement according to different surface materials. Permeable paving bricks are generally used in city squares, construction community roads, pedestrian roads, parking lots and non-motor vehicle roads, etc. With the country's call and support for the construction of sponge cities, more and more roads will use permeable paving to reduce urban runoff. Although the existing permeable pavement has a certain effect of reducing the peak flow of rainwater and infiltrating, but due to Its own structure and construction level will cause the following problems: [0003] 1. Due to the poor perme...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the poor permeability of the cushion and foundation of the existing permeable paving bricks, the infiltration capacity of rainwater is insufficient;

[0004] 2. Most of the existing permeable paving bricks do not have water storage capacity, resulting in poor ability to cut peak and reduce rainwater runoff;

[0005] 3. The existing permeable paving bricks have poor air permeability;

[0006] 4. Due to the complex structure of some existing permeable bricks with water storage function, their construction is difficult and they are easily damaged during later use
