环保透水砖 ,那么为什么城市人行道要铺环保透水砖呢? Nowadays, more and more urban sidewalks have chosen to lay environmentally permeable bricks , so why should urban sidewalks be laid with environmentally permeable bricks? The editor of Wanxin Pipe Industry took everyone to see the benefits of laying environmentally permeable bricks on the sidewalk.

1. Ecological and environmentally-friendly permeable bricks have very high water retention characteristics. The porosity has reached 25%. Generally, the water retention capacity is about 12L / m2 in the form.
For example, a standard football field is 105 meters long, 68 meters wide, and has an area of 7,140 square meters, which is the size of a football bureau's ecological and environmentally-friendly water storage capacity to store 86,000 L of rainwater. This does not include the grass-roots water storage capacity, so laying environmental protection Pervious bricks are equivalent to building a small reservoir in the city. When it rains, the environmentally-friendly permeable bricks can absorb and store moisture. Under the sunlight, it will slowly evaporate and then reach the function of lowering the surface temperature.

2. The permeability rate of water-permeable ecological and environmental-friendly permeable bricks is more than 20mm / s, which is more than twice the national standard. It can cope with the precipitation of 60mm / h. Use it to pave the sidewalks or squares. Rainwater can quickly infiltrate and prevent urban floods. Disasters can also supplement open water, improve the living environment of vegetation, be able to accept heavy rainstorm attacks, reduce investment in water supply and drainage equipment, and prevent losses caused by heavy rain to the city.

It is the water-retaining property of the environmentally-friendly permeable bricks that prevent water from accumulating on the pavement, which allows pedestrians to walk. Therefore, in the establishment of cities, road drainage equipment can be greatly saved, and urban ecology can be promoted.
