Recently walking on the street, I found that the colorful floor tiles that had not been laid for a long time just disappeared quietly, and replaced with a slightly rough, natural and simple floor tile. This is a high-permeability, high-strength concrete pavement brick made of new environmentally-friendly water-permeable materials. This kind of brick is being implemented in Beijing on a large scale with the support of the government, and has been used in many communities in Beijing and on the sidewalks of the Second Ring Road and the Third Ring Road.
所出产的 生态陶 This environmentally-friendly permeable pavement brick is an ecological ceramic produced by Guangzhou Wanxin 具有高强度、高透水性、可以吸收热量和噪音、不积水、不打滑等特色，是一种满意生态环境要求的高新技能产品，可以摒弃“逝世性地上”的许多缺陷。 Porcelain permeable bricks have the characteristics of high strength, high water permeability, can absorb heat and noise, no water accumulation, no slipping, etc. It is a high-tech product that satisfies the requirements of the ecological environment and can abandon many of the defects of "dead ground". There are the following five characteristics in detail:
First, it has outstanding water permeability and ventilation functions, which can make rainwater quickly enter the ground, make up for soil water and groundwater, adhere to soil moisture, and improve the living conditions of urban plants and soil microorganisms.
Secondly, it can absorb water and heat, and regulate the temperature and humidity of some surface space, which has a greater effect on conditioning the urban microclimate and alleviating the urban heat island effect.
Third, it can reduce the pressure of urban drainage and flood prevention, and has an outstanding effect on avoiding pollution of public waters and treating sewage.
Fourth, there is no water accumulation after the rain and no slippage after the snow, which is convenient for citizens to travel.
Fifth, the surface is slightly concave and convex, to avoid road reflections, to absorb noise that occurs when the vehicle is running, and to improve the comfort and safety of the vehicle.
In recent years, some European cities have widely used ecological and environmentally-friendly permeable areas. Germany, known for its environmental skills, rarely sees water on the ground. Their experience is to use permeable floor tiles in the places where there is not much pressure, such as sidewalks, pedestrian streets, bicycle lanes, and suburban roads. The permeable filling materials are used for stitching between bricks and bricks. For bicycle storage places and parking lots, select Concrete bricks with holes and filling with soil at the top of the brick holes to facilitate weed growth and make 40% of the ground beautify the function; in residential areas, parks, and street squares, solid bricks are used for paving the road, but between bricks and bricks, Leave empty space, soil is left in the open space, natural grass can grow here, which can constitute 35% of the landscaping area; around the houses, residential walkways, schools and park walkways, because there are more pedestrians , Use fine gravel or fine cobblestone to pave the road, not only the ground has good water permeability, but also weeds are not long; the main pavement of the city street is paved with perforated bricks and gravel, that is, dust is scattered in the holes of the floor tiles with holes. Stone can make rainwater penetrate smoothly, and its heat reflection on the ground is greatly reduced. In the new "Concrete Pavement Bricks" code, Germany stipulates that if a pavement tile with a surface layer is made, the surface layer concrete must be firmly bonded to the bottom concrete and have more than 10% of pores to allow water to enter the ground.
Germany's policy is that by 2010, 90% of the pavements in cities across the country will be converted to permeable ground.
If the type of ground hardening used is construction yards, squares, parking lots, sidewalks, pedestrian streets, bicycle paths, etc., pervious materials should be selected for pavement in accordance with the construction specifications, or confluence equipment should be constructed to introduce rainwater into the pervious area for storage, recharge, or introduction. Water storage equipment is stored. If the type of ground hardening is basic equipment such as urban arterial roads and traffic arterial roads, the road rainwater should be combined with landscaping irrigation along the line to plan and build rainwater equipment. Guangzhou Wanxin is carefully crafted for you, so that you can save your mind and effort!
