The pavement paved by Wanxin permeable bricks is not only a problem of the pavement material itself, but also the support of the roadbed, the system for collecting the incoming water and a series of related technologies. But now, our technical level can't meet such requirements.
Because Wanxin permeable bricks have outstanding breathable and permeable functions, the new Jianqi permeable bricks are more effective in penetrating moisture and then reaching the humidity distribution function.
Permeable bricks are laid in the city, as if the aerobic breathing of the city is increased, so that the entire air becomes more fresh and natural.
In the long past, the streets, squares, and courtyards of residential quarters in the city were mostly paved with granite, cement, and glazed tiles.
Therefore, almost all cities are facing the same dilemma. On the one hand, many hardened grounds cause urban rainwater to not penetrate into the ground, and the groundwater level drops because it cannot be made up by rainwater;
On the other hand, the accumulated water on the pavement surface hardens on rainy days, causing inconvenience to pedestrians and traffic, and even waterlogging due to incomplete urban drainage facilities. The occurrence of a new type of Jianling brick can quickly absorb surface water.
After the brick body is soaked, water moves in the open space between the bricks and eventually flows into the underground drainage pipe. If permeable bricks are laid on the streets of the city, even in heavy rainfall, the municipal drainage capacity can be reduced to avoid water on the road area.
In addition, Jianling bricks can also absorb heat and regulate the temperature and humidity of some space on the surface, which has a greater effect on alleviating the urban heat island effect.
Of course, there are some flaws in permeable bricks. His cushion cannot use concrete cushions, because the use of concrete cushions loses the significance of choosing permeable bricks. Water cannot enter the bottom layer through Jianling bricks, which will cause water accumulation.
In order to make Jianling bricks permeable, fine sand is used as a cushion layer during construction. The bricks and bricks are not bonded with mortar, but are fixed on the sand layer by means of kneading.
This can sometimes lead to road inequality. However, there is no need to worry about the compressive capacity of Jianling brick. The permeable brick is small in size, high in thickness, and relatively high in compressive capacity.
