Because the permeable brick has excellent air-permeable and water-permeable functions, the new type of permeable brick is more effective in penetrating moisture and reaching the role of dispatching humidity. Permeable bricks are laid in the city, as if the aerobic breathing of the city is increased, and the entire air becomes more fresh and natural. In durable past, the streets, squares and courtyards of residential quarters in the city were mostly paved with granite, cement, glazed tiles and other materials.
Therefore, almost all cities face the same embarrassment. On the one hand, a lot of hardened ground constitutes urban rainwater that cannot penetrate into the ground, and the groundwater level drops because it cannot be compensated by rainwater; on the other hand, the hardened surface water on the road surface in rainy days gives pedestrians And inconvenience caused by transportation, and even waterlogging due to incomplete urban drainage equipment. The occurrence of a new type of permeable brick can absorb surface water sensitively. 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 and water on the road area can be avoided.
In addition, permeable bricks can also absorb heat and regulate the temperature and humidity of some surface spaces, which has a greater effect on mitigating the urban heat island effect. Of course, there are some defects in permeable bricks . His cushion cannot use concrete cushions, because the use of concrete cushions has lost the meaning of choosing permeable bricks . Water cannot pass through the permeable bricks to the bottom layer, which will cause water accumulation. In order to make the permeable bricks permeable, fine sand is used as a cushion layer during construction. The bricks and bricks are not bonded with mortar, but fixed on the sand layer by the effect of kneading. This can sometimes lead to road inequality. However, there is no need to worry about the compressive ability of permeable bricks . The permeable bricks are small and high in thickness, and their compressive ability is relatively high.
