The dispersion effect of permeable bricks and ordinary bricks is not the same, especially after the heavy rain, the water on the permeable brick pavement has not yet been shown, and the green lawn is suspended. The road here is composed of gray or light red bricks. The surface is covered with holes, very soft feet. Set a basin of water to pour down, and the water seeps down the blank of the brick system. Immediately, the bricks on the water surface are gone. Because the permeable bricks are laid, the rain can quickly enter the ground and be in the room. The roof, road and courtyard rainwater use system covers a 5700 square meter depression oasis.
Permeable brick , as the name suggests, is a floor tile that can penetrate water, because of its large porosity, it encounters heavy rain.
When you can make a waterline, reduce surface runoff and effectively recover the surface water cycle system, together, it also provides an effective way for the recycling of industrial waste.
In the meantime, permeable bricks use desert sand as the material, have good waterproof performance, non-slip, and are not easy to be dusted like ordinary permeable bricks . Sand permeable bricks are difficult to enter the market, mainly due to the high cost. Because of the production process of sand permeable bricks , even No matter how low the cost is, it can't be cheap to tens of yuan, and whether it is a real estate developer or an engineering part, it takes a process to withstand this high-tech product.
What is the cause of the symptoms of "not adhering to water and soil" permeable bricks ? Because permeable bricks are generally under sand, the porosity of the stone permeable bed is large, and they are accumulated in dust such as long-term adsorption and deposition. These places may constitute blockages and the water permeability will decline. It even completely lost the ability to soak.
In northern areas, the outdoor temperature is low in winter, and the porosity of snow and rain infiltration produces frost heave damage through repeated freezing and thawing.In addition, the density and compressive strength of permeable bricks are lower than those of normal hardened road and floor tiles, and the frost cracking is more severe.
To have good permeability, it is a short set. It is very important. In order for the permeable bricks to exert their own effects, we must do all above-ground and underground work, and the underground rainwater collection system constitutes a "storage and permeation, Combining organic systems ".
