With today's fast-paced urgency, people are more unscrupulous in using resources to develop a fast economy, and do not pay much attention to environmental benefits, which has led to the accumulation of water in the environment of major cities, and the problem of continued decline in groundwater levels is still slow. Not processed. According to the editor of the Jiujiang Sponge City, in order to deal with these problems, the most basic information in the construction of the pavement of the sponge city is permeable concrete bricks. At present, many cities have a common problem that has not yet been addressed, that is, the use of rainwater is not used. The groundwater level dropped sharply.
We usually use concrete roads, but as far as the ground environment is concerned, this kind of road that is completely impermeable to air and water is the "death zone". And recently, rainwater resources have gradually been paid attention to. In order to fully use rainwater resources, permeable concrete bricks have become the best choice to save the "death zone". The permeable concrete brick has a honeycomb-like uniform open space, which has great advantages in terms of water permeability, air permeability, and weight. It is also because of its large open space that not only can effectively supplement groundwater, but also can serve as a medium for transmitting low temperature to the air underground, alleviating the heat island effect.
Pervious concrete bricks also have the same advantages as ordinary pervious bricks . Patterns like laying can be made according to the designer's ideas. However, it is stronger than ordinary permeable bricks, and it has a higher water infiltration efficiency, and can quickly make water flow into the ground; in the later maintenance, it only needs to be washed by high-pressure water washing. Its large open space can effectively increase the humidity of urban air. So can continue to carry on the city, the pervious concrete pavement bricks is an inevitable choice in the trend.
