Further, it is also connected with up big and down small collection funnel at the top of the collecting pipe, and collection funnel Top surface is flushed with the top surface of base, increases the collecting zone of rainwater using collection funnel, so that rainwater is discharged from drainpipe as far as possible Fall.

Further, latticed filler is filled in the collection funnel, latticed filler plays support and collects The effect in funnel space avoids when laying cutting optimal in base single-stage from entering collection with partial size Steel slag permeable asphalt mixture In pipe and collecting pipe, cause drainage efficiency poor.

Further, the latticed filler is made of the superposition of Multilayer Network panel, and structure is simple, easy to process, peace Dress.

Further, the latticed filler is made of plastic material, is played stable support to cutting optimal and is made With, and plastic material is corrosion-resistant, long service life.

Further, the latticed filler is made of hardboard, after prolonged rain erosion, firmly Latticed filler made of cardboard can decompose, so that collection funnel can preferably collect rainwater, ensure rainwater discharge Circulation.

Further, the base is cement stabilized macadam base, and is provided with skeleton, and structure is simple, Control the cracking and breakage problem of pavement structure.

Further, the single-stage of the steel slag of the cutting optimal is 9.5~13.2mm, the single-stage of the steel slag of middle surface layer with partial size It is 4.75~9.5mm with partial size, the single-stage of the steel slag of upper layer is 2.76~4.75mm with partial size.Upper layer uses lesser grain Structure is spent, ensure that its wear-resisting and rugged performance, middle surface layer and cutting optimal use biggish steel slag Granularity Structure, improve infiltration effect Rate effectively avoids surface gathered water.

Further, the cutting optimal with a thickness of 10~15cm, middle surface layer with a thickness of 10~15cm, the thickness of upper layer Degree is 6~10cm.

Compared with prior art, the utility model advantage is:

Permeable pavement structure described in the utility model has good water permeability, and the rainwater on road surface is permeated It concentrates and discharges to subsurface, avoid rainwater from forming runoff and ponding in the road, alleviate the burden of municipal drainage pipeline, it can be with The appearance of waterlogging is avoided well, improves travel safety and comfort.
