Permeable city pavement structure and rainwater collecting and utilizing system based on permeable pavement

Abstract

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.

Description

technical field [0001] The invention relates to the related technical field of municipal engineering, in particular to an urban permeable pavement structure and a rainwater collection, utilization and discharge system based on the permeable pavement. Background technique [0002] Permeable pavement is also called porous pavement, including permeable concrete pavement and OGFC (open graded anti-skid wear layer) asphalt pavement, etc. There are a large number of penetrating pores inside the coarse aggregate skeleton. The high-porosity structure of the permeable pavement allows rainwater to infiltrate effectively into the ground, reducing urban surface runoff. Under the guidance of the concept of sustainable development, the research and application of permeable pavement engineering in my country has developed rapidly in recent years, which will play a huge role in solving the problem of poor drainage in metropolitan cities. [0003] However, in the current urban construction,...
