Permeable pavements and permeable systems

Abstract

The permeable pavement and permeable system provided by the invention relate to the technical field of road engineering. The permeable pavement includes a partition structure, a water retention structure and a drainage structure. The water retention structure and the drainage structure are arranged side by side. The partition structure is arranged between the water retention structure and the drainage structure, and separates the upper side of the water retention structure from the upper side of the drainage structure. The side is connected and communicated with the lower side of the drainage structure. The water retention structure is used to store rainwater and is able to convey excess water to the drainage structure. The drainage structure is used to receive the water body output by the water retention structure and discharge the excess water body. Under the premise of ensuring structural stability, the permeable pavement can realize the storage of rainwater and prevent the pavement from flooding.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a permeable pavement and a permeable system. Background technique [0002] With the popularization of hardened pavement, the original natural ecological and hydrological characteristics of the city have been changed. On the one hand, groundwater resources cannot be replenished in a timely and effective manner, causing urban surface settlement; on the other hand, rainwater cannot infiltrate, which is not conducive to rainfall. time drainage. [0003] However, in the prior art, it is impossible to take into account the storage of rainwater and the stability of the roadbed, or the rainwater will wash away the roadbed, causing damage to the road surface; or it cannot play the role of rainwater storage. Contents of the invention [0004] An object of the present invention is to provide a permeable pavement, which can store rainwater and prevent flooding of the surface unde...
