The pavement paved with permeable bricks
is not only a problem of the pavement data itself, but also the support of the subgrade, the system for collecting water, and a series of related skills. But now, our skill level can't meet such requirements.
Since the people The permeable brick
has excellent air-permeable and water-permeable functions. Permeable bricks are
even more effective in soaking moisture and reaching the effect of dispatching humidity.
City laid The permeable brick
is the same as adding aerobic breathing to the city, making the whole air more fresh and natural.
Before the endurance, most of the city's streets, squares, and courtyards in residential quarters were paved with granite, cement, and glazed tiles.
As a result, all cities are facing the same dilemma. On the one hand, many rainwater on the hardened ground cannot penetrate the ground, and the groundwater level drops because it cannot receive rainwater compensation;
On the other hand, the accumulated water on the pavement surface hardens on rainy days, causing inconvenience to pedestrians and traffic, and even waterlogging due to imperfect urban drainage equipment. The outbreak of a new type of Jianling brick can actively absorb water on the surface.
After the brick is soaked, water moves between the bricks and the bricks, after all, it flows into the underground drainage pipe. If laid on the city's streets Permeable bricks
can reduce municipal drainage capacity even in heavy rainfall and prevent road area water.
In addition, Jianling bricks can also absorb heat and regulate the temperature and humidity of some surface spaces, which has a greater effect on mitigating the urban heat island effect.
There are also some defects in permeable bricks
. His cushion cannot use concrete cushion, because the use of concrete cushion has lost its selection.
The meaning of permeable bricks
, water cannot pass through the Jianling brick to enter the bottom layer, and it will form stagnant water.
In order to make Jianling bricks permeable, fine sand is used as a cushion during construction. The bricks and bricks are not bonded with mortar, but fixed on the sand layer by the effect of kneading.
This can sometimes lead to outbreaks of road inequality. But there is no need to worry about the compressive talent of Jianling Bricks, The permeable brick is
small in size and high in thickness, and has relatively high compressive talent.
"Look, this is how water permeates from bricks. When it is paved on the road, it can absorb, retain, and release water. It can also regulate air humidity and absorb suspended particles to reduce haze." Pico in Oasis Zhang Cuimei, the director of Shaanxi Sunshine Rain Ecological Technology Co., Ltd Pervious brick
It is understood that the reason why this brick is called an ecological product, because it uses urban construction waste as a material, while beautifying the environment also adds artistic color to the city. The permeable brick
has excellent moisturizing function, which can well alleviate the "urban desertification" and "heat island effect" caused by the imperviousness of urban floor coverings. It can also compensate for the increasingly dry groundwater resources in urban areas and play a role in the storage of permeable roadbeds. Pool function.
The company's chairman, Xing Jingfei, was the project leader of Weinan Engineering Construction Company. In 2002, he inquired abroad and found that there were large-scale water storage tanks underground in developed cities, which ensured smooth drainage during the flood season and completed the reasonable use of rainwater. After returning home, he decided to resign, and after four years of painstaking research, in 2006, he announced that ygy's minimally invasive water-permeable skills and high-performance water-permeable agents were passed by the Ministry of Science and Technology.
"Our southern city has a severe haze phenomenon. The first is monotonous air. Suspended particles cannot settle in time due to lack of water vapor adsorption. Permeable bricks
can help improve this phenomenon. Xing Jingfei informed the reporter, "This kind of Permeable bricks
are 20% more expensive than ordinary bricks, but we will continue to develop and gradually reduce the cost to make them more affordable. "
Since December of last year, the company has successively created supply products for the Xixian New District, and has now been widely used in Guangzhou New District.
