Preferably, the pervious asphalt layer includes being laid on the porous asphalt layer of top and under porous asphalt layer The pervious concrete face layer of side.
By using above-mentioned technical proposal, by setting pervious asphalt layer to porous asphalt layer and pervious concrete face Layer, the hole of pitch is larger in porous asphalt layer can be preferably permeable downwards, and pervious concrete face layer is non-fine concrete system At, using made of the material pervious concrete face layer have well water penetration and can improve the utility model structure it is strong Degree.
Preferably, being provided with glued layer between the pervious concrete face layer and porous asphalt layer.
By using above-mentioned technical proposal, glued layer is organosilicon epoxy resin as made by cementing material, by the material Expect that the glued layer being formed with has outstanding adhesive property, the globality of pervious asphalt layer can be enhanced.
Preferably, being provided with the shim for filling up sub-surface gap between the sub-surface and drainage blanket.
By using above-mentioned technical proposal, sub-surface is that natural soil is tamped to be formed, and structure is more loose, and surface holds Easily there is gap, by the design of shim, shim is sprayed on sub-surface for asphalt and is formed, by the material spraying The shim of formation can penetrate down into the gap of sub-surface and then fill up these gaps, to enhance the table of sub-surface Surface intensity and globality.
Preferably, the thickness of the porous asphalt layer is 20-25mm.
By using above-mentioned technical proposal, the thickness of porous asphalt layer is 20-25mm, is ensureing the same of preferable structural strength When save construction cost.
In conclusion the utility model has the advantages that:
By being designed with weeper drain and dropping down onto the water guide module of rainwater diversion to weeper drain on pavement structure Rainwater can be converged along water guide mould water barrier in the block to importing water storage in weeper drain from weeper drain again late or catch-basin It is interior.
