Permeable city pavement structure and rainwater collecting and utilizing system based on permeable pavement
The invention relates to a permeable city pavement structure and a rainwater collecting and utilizing system based on the permeable pavement. The permeable city pavement structure mainly comprises an anti-blocking permeable pavement layer. An open-graded cushion layer, an open-graded upper base layer, an open-graded lower base layer and a non-compaction foundation soil layer are sequentially arranged under the anti-blocking permeable pavement layer. A water drainage pipe with holes is arranged in the open-graded lower base layer. Rainwater continues to seep downwards after being filtered through the anti-blocking permeable pavement layer, a part of the rainwater enters the water drainage pipe after passing through the open-graded cushion layer, the open-graded upper base layer and the open-graded lower base layer, and the other part of the rainwater continues to seep downwards and seeps underground after passing through the non-compact foundation soil layer. By means of the brand-new pavement structure, while the rainwater can be conveyed through a pipeline, the rainwater seeps underground by means of the base layers, and the problem of pavement flood propagation caused when rainfall in a city is large is effectively solved.
