Sponge city means that the city can adapt to environmental changes and cope with natural disasters like a sponge. When it rains, the city absorbs water, stores water, seeps water and purifies water. If necessary, it releases the stored water and makes use of it. Traditional city construction mode is extensive and destructive, while sponge city has very low impact on the surrounding ecological environment. Therefore, sponge city construction is also known as low impact development.
This great project can make the city more beautiful by building green roof and Rainwater garden, but also controls rainwater runoff so that the ecological environment can be flexibly adjusted.
Sponge city is not a dream. It has already achieved certain results in Germany, the United States, Singapore and other districts. Permeable concrete has undoubtedly become a good helper for this amazing project. In the process of construction of sponge city, paving permeable ground, also called ecological permeable ground, can make rainwater infiltrate into the surface rapidly. As an invisible drip irrigation of sponge city, it can effectively supply groundwater and protect the natural water system of the city from being destroyed, which has strong environmental protection value.
