Simple comparison of concrete bricks and permeable bricks
During the construction of cities in the past many years, most of the roads in the city were paved with cement products such as stone slabs and concrete bricks. The fields of use are as many as sidewalks, bicycle lanes, suburban roads, open-air parking lots, courtyards, streets, and streets. Public squares and other places. Although the function of concrete bricks is excellent, the demand for pavements in cities is relatively high. Therefore, through years of research and development, Chinese professionals have produced a series of pavement bricks and put them into urban pavement construction projects. Among them are water- permeable bricks
with excellent water-permeability
, hydraulic bricks widely used in urban fountains and other places, outstanding porous bricks, and interlocking blocks that can only receive strong loads. Due to the variety of pavement tiles, their share in shopping malls is also expanding.
Although the laying of hardened pavements is used for regular warping, its biggest drawback is impermeability. Impervious road surface will completely stop the compensation of groundwater by rainwater during rainfall. In cities that rely on groundwater as a source of drinking water, the rapidly falling groundwater level is difficult to rise. When it rains heavily, the drainage of rainwater will not be smooth, and water will form on the streets and streets of the city, which may cause floods on the side of the city, and the rainwater will accumulate on the road. On the one hand, it will cause traffic jams and increase the pollution of motor vehicle exhaust emissions. In terms of rainwater, many urban pollutants, such as heavy metals emitted by cars and pesticides sprayed on urban grasslands, are dissolved during the crossflow. These rainwaters are directly discharged into local rivers through pipes, which will cause a certain degree of pollution to the environment.
The laying of pavement tiles with excellent water permeability can not only deal with the urban water accumulation that occurs during heavy rain, but also prevent the occurrence of various urban pollution to a certain extent.
