Background

In recent years, the urban water logging disasters are frequently reported, mainly due to poor water seepage of urban pavements, the traditional urban drainage cannot timely dredge a large amount of rainfall, and an internal drainage system is old and blocked. In view of the situation, the concept of sponge city gradually draws social attention. Sponge cities, as a new generation of urban rainfall flood management concept, are expected to have excellent drainage capacity to cope well with disasters such as flooding.

The ecological permeable pavement is an important component of a sponge city. Currently, permeable pavements are often constructed by using permeable materials, such as porous lightweight concrete made by mixing coarse aggregate, cement and water, or by using gaps between paving tiles. However, such a permeable pavement has the following problems: firstly, the road paved by the water permeable material has the advantages that the water permeable pores are easily blocked by sand mud dust, so that the water permeability is reduced, and even the water permeable function is completely lost; secondly, the pavement of the permeable material is adopted, and the permeable material is provided with pores for water permeability, so that the traditional permeable pavement has poor bearing capacity, higher manufacturing cost, low cost performance and low cost performance; finally, the traditional permeable pavement is difficult to maintain, and once the permeable material loses the permeable function, the permeable pavement is difficult to repair, and can only be integrally replaced after being broken, so that the cost is high, and the engineering is complicated.

In order to solve the above problems, patent CN204728165U discloses an ecological permeable pavement, which adopts a vertical water guiding pipe, the water permeating into the permeable brick layer can enter the upper end opening of the water guiding pipe and flow down to the gravel layer or the gravel layer, and the gravel clearance between the gravel layer and the gravel layer is utilized to contain a large amount of water, so as to achieve the purpose of reducing the water accumulated on the pavement, however, dust and sundries are easily accumulated in the water guiding pipe, so that the water guiding pipe is blocked and loses the flow guiding effect. Patent CN206692979U discloses a permeable pavement, this permeable pavement utilizes vertical water conservancy diversion way to guide the rainwater of gathering on the road surface to the underground, utilize the upper end of seal block shutoff water conservancy diversion way simultaneously, utilize the rainwater inflation rubber back to strut the seal block and open the water conservancy diversion way in the rainwater day, this kind of mechanism structure is complicated to be used on a large scale, the cost of mating formation is high, and utilize water to trigger the water conservancy diversion way not only can lead to local water conservancy diversion way draft inflation to open, cause the dust debris to get into, and the dust debris that get into in the water conservancy diversion way also can't wash effectively.
