Yesterday morning, the reporter came to Yijiang Anyuan Community, which is located on the Qingshan River. The representative of the owner of Sponge City Construction Co., Ltd. Wang Sicheng introduced that the entire community has transformed as much as possible the parts that can be modified with sponge equipment. The leisure plaza and parking lot were covered, and the pedestrian walkway was paved with water.


"Sponge cities have several principles: seepage, stagnation, storage, cleanliness, use, and drainage. This rainwater garden embodies the above criteria." Wang Sicheng said that when the rain is particularly heavy, the rainwater will be passed through the rainwater garden first. Short-term storage, then infiltration or flow into overflow wells, this process slows down the rate of rainwater entering the municipal pipe network, and then reduces the drainage pressure of the municipal pipe network during heavy rainfall. The rainwater has become the living water for the aquatic plants grown in the garden.

Wang Sicheng explained that the permeable brick is made of larger particles with a gap in the middle. Under the permeable brick , there are gravel layers, sand layers and pre-buried seepage pipes. Rainwater can quickly infiltrate, and through the gravel and sand, Layer filtration also objectively played a purification effect.

Yang Lasheng, the person in charge of the owner committee of Yijiang Anyuan Community, said that before the reconstruction of the sponge city, when there is heavy rain, there will be standing water on the community road. On the 16th, he checked in the community and found that there was almost no standing water on the road, and the rainwater was digested on the spot. "The residents felt unimaginable and very satisfied."
