At the beginning of 2015, the offices of the Ministry of Finance, the Ministry of Housing and Urban-Rural Development and the Ministry of Water Resources jointly issued the "Notice on Organizing the Declaration of the 2015 Sponge City Construction Pilot City" (Caibanjian [2015] No. 4), announcing that the central government will support the city to increase rainwater The interception and utilization project was officially launched. The time to declare the first batch of pilot cities will be closed by the end of February 2015.
According to the spirit of the “Notice on Launching the Pilot Work of the Central Finance Supporting the Construction of Sponge City” by the Ministry of Finance, the Ministry of Housing, Urban and Rural Construction and the Ministry of Water Resources (Caijian [2014] No. 838), the central government will provide Special funding subsidies will be given to the sponge city construction pilot. The specific subsidy data will be determined according to the city's scale. The municipalities directly under the central government will be 600 million yuan a year, the provincial capitals will be 500 million yuan a year, and other cities will be 400 million yuan. For a certain percentage of the PPP model, 10% will be awarded based on the above subsidy base. It is reported that the major cities that have been declared pilot include provincial capital cities like Nanning and Shijiazhuang.
What is a "sponge city"? If one word is used to describe the "sponge city", it can be summarized as follows: in the process of urban construction, it can absorb, infiltrate and use rainwater to the greatest extent to improve the urban environment. Permeable pavement operation is one of the main measures for the construction of "sponge city", and it is recommended to be the preferred material for pavement of squares, parking lots, sidewalks, and light-loaded roads; The primary recommended measure of technology. The most direct indicator of the "sponge city" is: the city's utilization of rainwater is greater than 60%. In this "Guide", it is recognized that the permeable brick paving has the outstanding advantages of low construction and maintenance costs.
It is expected that in the next 5 years, permeable concrete pavement bricks and pavement bricks with gap permeable function will show a rapid growth trend for a long time and the proportion of the total volume of concrete pavement bricks (boards). In addition, new concrete curbstone products that meet the needs of sunken green space construction will be developed, produced, and utilized; slope protection (retaining wall) blocks will also become supporting products for urban wetlands or water storage ponds, and will be widely used.
After research and development and production, our company has developed a series of color permeable concrete pavement brick products, which can produce different specifications and requirements of color permeable concrete pavement bricks according to the construction location. The production process of the permeable pavement brick products mainly includes strict raw materials Screening and selection of cementing materials, special design requirements of molding equipment, and the particularity of raw material mixing use a series of production processes such as special concrete mixing equipment.
At the same time, UNIK has also developed concrete block manufacturing equipment suitable for various water-permeable products according to the characteristics of water-permeable properties. Friends from home and abroad are welcome to visit and investigate the company.
