The utility model discloses a following technical scheme realizes:
a permeable sidewalk pavement structure with a drainage channel comprises a roadbed, a cushion layer, a base layer, a leveling waterproof layer and a permeable surface layer which are sequentially arranged from bottom to top; the permeable surface layer adopts permeable bricks with drainage channels; rainwater seeps into the drainage channel through the water permeable bricks with the drainage channel, and then the rainwater is drained to the edge of the sidewalk through the cross slope of the drainage channel and is drained into the rainwater well.
Furthermore, the water permeable bricks with the drainage channels can adopt hollow water permeable bricks, and when the hollow water permeable bricks are paved, the hollow parts in the middle of the hollow water permeable bricks are correspondingly paved to form the drainage channels.
Furthermore, the hollow part in the middle of the hollow water permeable brick can adopt an arc hollow part, a rectangular hollow part or a circular hollow part.
Furthermore, the water permeable bricks with the drainage channels can adopt I-shaped water permeable bricks, and when the I-shaped water permeable bricks are paved, the hollow parts on the two sides of the I-shaped water permeable bricks are correspondingly paved to form the drainage channels.
Further, the leveling waterproof layer comprises a sand cushion layer for leveling the water permeable surface layer; and a waterproof layer arranged on the lower side of the sand cushion layer for preventing water.
Furthermore, the waterproof layer adopts waterproof geotextile.
Furthermore, the roadbed comprises lime soil, cement soil, plain soil and gravel soil.
Furthermore, the cushion layer comprises a gravel cushion layer and graded gravel.
Further, the base layer comprises concrete, cement-stabilized macadam and lime-fly-ash macadam.
(III) advantageous effects
The utility model provides a pavement structure of mating formation of permeating water with drainage channel compares with prior art, and it has following beneficial effect:
(1) in the technical scheme, the water permeable surface layer is arranged on the top surface and adopts water permeable bricks with drainage channels; the structure of the water-permeable sidewalk is simplified, and the construction period of the water-permeable sidewalk is shortened. The drainage channel is arranged on the permeable surface layer, the downward seepage distance is short, and the situation of dredging blockage can be avoided; even when the channel is blocked, the later maintenance is more convenient.
(2) The technical scheme is that the water permeable bricks with the drainage channels are directly paved by adopting hollow water permeable bricks or I-shaped water permeable bricks, and when the water permeable bricks are paved, the drainage pipelines are paved. The process has two effects, other drainage pipelines do not need to be paved, the material of the permeable sidewalk paving structure is saved, the cost is reduced, and the flow of paving the drainage pipelines is saved; further shortening the construction period.
(3) This technical scheme sets the leveling waterproof layer to be used for carrying out the sand cushion layer of leveling to the surface course that permeates water and sets up and be used for waterproof layer in sand cushion layer downside, has played the effect of protection to road bed, bed course, the basic unit of setting in the layer downside that permeates water, can effectively increase the intensity of road bed.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are only some, but not all embodiments of the invention. Under the prerequisite that does not deviate from the design concept of the utility model, the ordinary person in the art should fall into the protection scope of the utility model to the various changes and improvements that the technical scheme of the utility model made.
Example 1:
as shown in fig. 1, a permeable sidewalk pavement structure with a drainage channel comprises a roadbed 1, a cushion layer 2, a base layer 3, a leveling waterproof layer 4 and a permeable surface layer 5 which are sequentially arranged from bottom to top.
In this embodiment, the following materials are specifically used for each layer:
the roadbed 1 is obtained by compacting or pouring lime soil, cement soil, plain soil and gravels.
The cushion layer 2 is paved and compacted by adopting a gravel cushion layer and graded gravel.
The base layer 3 is obtained by compacting or pouring concrete, cement stabilized macadam and lime-fly-ash macadam.
The leveling waterproof layer 4 comprises a sand cushion layer for leveling the permeable surface layer; and a waterproof layer arranged on the lower side of the sand cushion layer for preventing water; the waterproof layer adopts waterproof geotextile.
