Concrete pavement brick capable of achieving gap water permeation and self water permeation

Abstract

The invention relates to a concrete pavement brick capable of achieving gap water permeation and self water permeation. The integral body of the concrete pavement brick is a rectangular building brick, wherein the four corners of the building brick adopt rounding corners; the building brick comprises a bearing base layer and an ornamental surface layer arranged on the base layer; the four sides of the surface layer and the base layer are arranged as approximately serrate concave-convex edges; one or more U-shaped or V-shaped bumps and grooves are arranged on the concave-convex edges; and blank holders with the size of 1-10 mm are arranged on the four sides of the surface layer. A base material and a surface material are respectively adopted for preparing the bearing base layer and the ornamental surface layer of the water permeation concrete pavement brick, and the concrete pavement brick not only has the color and texture of an archaistic sintered brick and but also has shock resistance and high load carrying performances and good water permeation performance; and the brick is convenient and quick to pave, adjacent bricks are interlocked firmly and reliably, and the paved water permeation pavement truly has double effects of functionality and ecological landscape.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to an ecological permeable concrete pavement brick with antique imitation stone for road squares and rainwater collection function, and also provides a preparation method of the ecological permeable concrete pavement brick . Background technique [0002] Urban rainwater is hazardous and resourceful. With the acceleration of urbanization, the area of ​​hard pavement and the groundwater resources that are easily consumed by buildings in cities cannot be compensated in time. The increasing density causes an increase in surface rainwater runoff, a decrease in infiltration rate, frequent floods and increased damage. In developed countries, the research on the collection and utilization of urban rainwater and its resource utilization started early, and many results and experiences have been obtained. Germany is one of the best countries in Europe to carry out rainwater utilizatio...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the technical problems of easy clogging and poor water permeability existing in the existing surface permeable bricks in China, and provides a kind of water permeable through the pavement gap of pavement brick blocks, which has a large water permeable gap, is not easy to be blocked, has high strength and is beautiful Ecological permeable concrete pavement bricks that are strong and can replace traditional quartz sand permeable bricks and porous sintered bricks, and give the method of using the permeable concrete pavement bricks to lay the permeable pavement and the maintenance and repair method of the permeable pavement during use
