A series of decree and methods made the concept of "sponge city" gradually known to people, and the city's waterlogging after heavy rains also allowed enterprises to turn their attention to the opportunities brought by the country's "sponge city" construction. As a key demonstration enterprise for the transformation and development of Yixing City, Wanxin Ecological Ceramic Pervious Bricks has been accustomed to market demand since it was put into production, and has continuously developed new products and expanded application fields. A few days ago, new permeable bricks went offline here.
"The company is precisely the key to the construction of the country's" sponge city ". With construction waste as the material, the research and development announced a new type of permeable brick with very strong water permeability . Its successful development will help the construction of our city and even the province's sponge city. "The accompanying company general manager told reporters that the water permeability can be improved under the premise of ensuring that the compressive strength does not drop. Even if the new type of permeable bricks suffer from heavy rainfall, they can also bring rainwater into the ground in a short time. Judging from the comparison of the appearance of the two bricks, the size and color are no different. Only the traditional bricks look lubricated on the surface, and the new permeable bricks are relatively rough. Through a comparative demonstration, the reporter saw that the water on the traditional bricks mainly drained from the surrounding unobstructed area. After the surface water was wiped off, there was no water seepage; the new permeable bricks , the water on the brick surface including the interior, passed quickly, and More water exudates from the bottom.
Regarding the advantages of permeable bricks , "on the one hand, you can add urban permeable and breathable areas, adjust the urban climate, and lower the surface temperature, which will help alleviate the" heat island phenomenon "in the city. Together, you can make full use of rainfall and snow and increase the relative humidity on the surface. To make up for the increasingly dry groundwater resources in urban areas, and play the role of "reservoir" for permeable roads. The reporter learned that high-efficiency permeable bricks are mainly suitable for road paving in urban sidewalks, parks, gardens and other places, because the surface of permeable bricks will not There is stagnant water, and the brick surface will not form ice in winter. People walk on it safely and will not fall or slip. Another is that its friction coefficient is also relatively large.
The construction of a new type of sponge city, the urban pipeline system has one more process than the traditional, rainwater collection system. When the rain or snow melts, it can pass through the bricks efficiently and quickly, which is equivalent to the more detailed water rafters. Therefore, similar phenomenon of water tank burst will not occur. Fan Xiaojun, a technician of the company, told the reporter, "The product has been experimentally matched for one month, and it is now basically shaped and can be mass-produced. All aspects of strength and water permeability have reached the national requirements. The product can be shipped after maintenance and natural air-drying."
The reporter learned that since the company put into production in 2013, Wanxin can now produce various colors, various types of hydraulic tiles, grass tiles, floor tiles, river slabs, antique bricks, permeable bricks , and recycled blocks. For other species, the annual output can reach 30 million yuan. Notify reporters that the company's next step is to continuously enrich its products and develop new products. Another is to actively raise and build a listing on the New Third Board.
