Description

Gardens permeable pavement structure

Technical Field

The invention belongs to the technical field of gardens, and particularly relates to a garden permeable pavement structure.

Background

Rainwater is a valuable and economical water resource in cities. The rainwater is guided to the non-closed road surface from the closed road surface or the roof and is subjected to infiltration filtration of soil, so that the strength of surface runoff of the rainwater can be reduced, the groundwater is supplemented, partial pollutants in the rainwater can be removed, and the rainwater is removed on site to reduce accidents caused by water accumulation. The filtered rainwater can be used as city non-drinking water, so that the demand of drinking water is reduced, water resources are saved, and the pressure of city water supply is relieved.

In addition, rainwater collection can save the construction cost of a drinking water distribution pipe network, and considerable economic benefits are obtained. Therefore, rainwater collection on the water permeable pavement is a feasible rainwater utilization technology, and the water permeable design of the water permeable pavement is widely applied to the construction of various pavements.

Since the 90 s of the 20 th century, it has become popular internationally to cover urban pavements with water-permeable materials or to change previously-laid hardened pavements into water-permeable pavements to enhance the ecological effect of cities. However, after long-term use, the micro-pores are easily blocked to influence the water permeable effect, and under the low-temperature climate conditions in the north in long winter, the brick body of the water permeable floor tile is easy to be frozen to cause the strength reduction, and the cost of the water permeable floor tile is higher, thereby influencing the popularization prospect.
