What's the difference between stone raft permeable ground and ordinary concrete?

1, the pervious concrete pavement is pervious, which can quickly eliminate the water in roads and squares when it rains; When the rainfall is concentrated, it can reduce the burden of urban drainage facilities and prevent river flooding and water pollution. 2, to prevent water accumulation on the road surface, not reflecting light at night, and increase the safety and traffic comfort of the road surface. 3. The water permeability of colored permeable concrete pavement can make rainwater quickly penetrate into the ground, reduce groundwater, maintain soil moisture, maintain the ecological balance between groundwater and soil, and avoid foundation settlement caused by over-exploitation of groundwater. 4. Permeable concrete pavement has a unique pore structure, which is close to the ground covered by natural vegetation in terms of heat absorption and heat storage, adjusting the temperature and humidity of urban space and alleviating the urban heat island effect. 5. The color permeable concrete system has large porosity, and the pavement has sound absorption function, which can reduce environmental noise. 6. A large number of gaps in the permeable concrete floor can absorb urban pollutants (such as dust) and reduce dust pollution. And the problem of hole plugging can be solved only by washing with high-pressure water. 7. The colored pervious concrete pavement has a series of color configurations, which can be designed according to the needs of the surrounding environment and has strong decoration.
