Cement-free pervious concrete brick

Abstract

The invention discloses a cement-free pervious concrete brick. The cement-free pervious concrete brick comprises first brick bodies, second brick bodies, inserting mechanisms and fixing mechanisms, the first brick bodies and the second brick bodies are connected through the fixing mechanisms, and the second brick bodies are located below the first brick bodies; and inserting mechanisms are arranged at the positions, close to the middle, of the outer surfaces of one sides of the second brick bodies and the first brick bodies correspondingly, and inserting grooves are formed in the two sides ofthe inner surfaces of notches correspondingly. According to the cement-free pervious concrete brick, through the arrangement of the inserting mechanisms, two adjacent groups of first brick bodies andsecond brick bodies are inserted, the firmness of the paved pavement is improved, and the loosening probability of the paved pavement is reduced, so that the flatness and the safety of the paved pavement are improved, and meanwhile, through the arrangement of the fixing mechanisms, the paved first brick bodies and second brick bodies can be fixed to the ground; and therefore, the stability of connection between the first brick bodies and the second brick bodies and the ground is improved, the service life of the paved ground is prolonged, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cementless concrete bricks, in particular to a cementless permeable concrete brick. Background technique [0002] Permeable concrete is a type of concrete developed and used by countries such as Europe, America, and Japan to allow rainwater to flow into the ground to effectively replenish groundwater for the defects of urban road surfaces. It can effectively alleviate urban environmental problems such as the sharp drop in urban groundwater levels, and can effectively eliminate Environmental pollution hazards of oily compounds on the ground. As an excellent pavement material that can effectively protect groundwater, maintain ecological balance, and alleviate the urban heat island effect, pervious concrete is usually made into permeable concrete bricks and widely promoted in many countries. [0003] The existing patent (notification number: CN108083744B) is a cementless permeable concrete brick, which belo...

Problems solved by technology

However, in the existing cementless permeable concrete brick laying process, in order to ensure its water permeability, it is directly paved, and then a large amount of rubber particles are introduced to fill it. Although this method is simple to operate, the paving The firmness of the pavement is poor, and there is no interlock between the bricks, which is prone to loosening and damage, which will cause passing pedestrians to fall or splash sewage when stepping on them, increasing the risk of pedestrians falling due to stepping on the bricks. risk, reducing its security;

[0006] 2. The existing cementless permeable concrete bricks are easy to loosen due to no external force to fix them during the paving process, especially in parks with relatively soft soil. Substantial fixation easily causes bricks to shift, thereby increasing their breakage rate and reducing the flatness of the paved ground. At the same time, due to the high breakage rate, regular maintenance is required by staff, resulting in use costs and manual maintenance. Increased costs

[0007] At the same time, the filled objects cannot fully contact the bricks, and there is no structure to fix the bricks, which is prone to loosening, and the strength and water permeability of the road surface are low, and the cost is high. Some sidewalks paved with facing bricks

[0008] In some cases, in order to improve the stability of the brick laying process, the operator will use a hydrophilic organic adhesive to connect adjacent cementless permeable concrete bricks, and in the process the operator will use a brush one by one The cementless permeable concrete bricks are glued. In order to make the connection between adjacent cementless permeable concrete bricks more stable, the operator will repeatedly brush the surface of the cementless permeable concrete bricks. However, the glue brushing process is long, which is easy to cause glue The viscosity is reduced, thereby reducing its adhesion effect and making the bricks easy to loosen
