Discussion-The water permeability performance of Zhongguan permeable bricks during use in sponge cities

&Discuss the water permeability of Zhongguan permeable bricks in the use of sponge cities
With the acceleration of urban construction, high-rise buildings abound. Coupled with the unlimited expansion of the city, the ground surface is gradually covered by various buildings and various natural Covered with stone or concrete. Convenient transportation and flat roads have brought great convenience to people's travel, but these impermeable roads have also brought many negative impacts to the urban ecological environment. Due to the lack of water permeability and air permeability of the paved road, rainwater cannot penetrate into the ground, which makes it difficult for surface plants to grow normally due to severe water shortage. Airtight pavement has difficulty in exchanging heat and moisture with the air, and lacks the ability to control urban surface temperature and humidity. The adjustment ability produces the urban heat island effect.
Rising urban temperatures consume a lot of energy, are not conducive to dust reduction and noise reduction, and will also affect climate change. If it is often cloudy and does not rain, resulting in reduced rainfall, people will feel like living on a sand dune in the afternoon. Vegetation consumes a lot of water resources and has difficulty growing normally.
Impermeable pavement prevents rainwater from seeping into the ground, and groundwater cannot be replenished in a timely and effective manner, causing the soil to harden and become sandy, until the city sinks. In a few years, our city will become a desert. On the contrary, the land we live on is like a big sponge, which can retain a large amount of water. It is a large underground reservoir. If the ecological balance can be maintained, it will play a huge role in our lives. As early as the last century, permeable brick paving, roof greening and permeable highway paving were implemented in developed countries, which greatly reduced the heat island effect and made full use of urban rainwater. Countries such as the United States and France have developed in this area. fast. Permeable brick paving and rainwater utilization form a surface recharge system and corresponding laws and regulations have been formulated to provide strong support for rainwater utilization and effectively improve the ecological environment.
The so-called permeable bricks, as the name implies, are ceramic tiles that can permeate water, allowing water to penetrate through the surface of the bricks into the bottom of the bricks and even into the ground to replenish groundwater. This is a new green and environmentally friendly product that has appeared in recent years.
[Zhongguan permeable bricks] are ideal pavement paving materials and can be widely used in parks, squares, sidewalks, residential areas and other places. They can regulate the temperature and humidity of people's living environment and maintain the ecology of the earth's surface. Balanced functionality.
As we all know, the streets in the cities and towns where we live are mostly paved with impermeable materials such as cement, asphalt, stone, ceramic tiles, etc., collectively called hardened pavement. When it rains, the pavement basically blocks the direct penetration of rainwater into the ground. Can only be discharged through sewer.
The special function of [Zhongguan permeable bricks] can solve this problem very well. During natural precipitation, it can quickly penetrate the surface and replenish groundwater. When the weather is fine, it can also drain the water inside the bricks and the surface. Due to its good air and water permeability, it can regulate the temperature and humidity of the surface, eliminate the heat island phenomenon, maintain ecological balance, and play the dual role of beautifying and mediating the environment.
The reason why [Zhongguan Permeable Brick] has such a function is mainly due to the fact that the product has a porosity of about %&, the water permeability can reach about /, and the water retention can reach /, so it is said that [Zhongguan Water Permeable Brick] Brick】has good water permeability and water retention. At the same time, due to the raw material formula, pressing molding, and high-temperature firing process requirements in production, the thickness of the product, the length, and the flexural strength can reach /, and it is fully suitable for pavements or floors in sidewalks, pedestrian streets, parks, parking lots, and residential areas. decorate.
