Recently, due to heavy rainfall in various regions, many areas have experienced flooding disasters!
For example: On July 7, 2017, it was reported that starting from the evening of July 5, Zigong City in Sichuan Province encountered heavy rainfall, affecting 80 towns (streets) in varying degrees, resulting in 1 death and direct economic losses amounting to 144 million yuan. Other data shows that since June 22, 2017, serious natural disasters have occurred in Ningxiang, Hunan, characterized by prolonged duration, wide range, heavy rainfall, and large intensity, marking the most severe natural disaster in Ningxiang in 60 years of hydrological and meteorological records. Preliminary statistics indicate that the number of people affected in the county is 815,000, accounting for 56% of the county's population, with a total of 44 people dead, missing, or accidentally drowned. Many other regions have also suffered from such severe natural disasters, causing harm to people and property!
Therefore, addressing urban flooding has become a crucial issue at present! Many urban roads cannot "absorb" rainwater, leading to significant water accumulation and even flooding during rainy days.
To solve urban flooding issues, we must start from urban road surfaces!
Permeable pavement is also known as eco-permeable pavement, permeable concrete, and no-sand concrete. Permeable pavement allows rainwater to quickly infiltrate the ground, effectively replenishing groundwater, mitigating urban heat island effects, and protecting urban natural water systems from damage, thus holding significant environmental value. Additionally, permeable pavement resolves the issue of water accumulation on regular pavements, enhancing safety and comfort for pedestrians, which is also crucial for improving living environments.
Moreover, permeable concrete retains the characteristics of traditional concrete while breaking away from its single gray color, showcasing a vibrant array of colors. Utilizing different colors allows the ground to blend with buildings and landscapes, creating a warm and harmonious living environment. It not only preserves the aesthetic appeal of urban road surfaces but also enhances their beauty.
Permeable pavement has the following advantages:
1. It can alleviate the burden on urban drainage facilities during concentrated rainfall and prevent river flooding and water pollution.
2. It allows rainwater to quickly infiltrate underground, replenishing groundwater and maintaining soil moisture.
3. It prevents water accumulation on road surfaces, does not reflect light at night, and increases road safety and comfort.
4. It regulates temperature and humidity in urban spaces, improves urban thermal circulation, and mitigates heat island effects.
5. Its large porosity can reduce surface noise when vehicles pass, creating a comfortable traffic environment.
6. The numerous voids can adsorb urban pollutants (such as dust), reducing dust pollution.
7. It is easy to maintain, the voids do not break, and it is not prone to clogging.
8. It can be designed with patterns as needed, fully integrating with the surrounding environment.
Permeable pavement can help you cross the road without "swimming"! Permeable pavement can also better and more quickly assist in achieving a "sponge city"!
