Abstract

The utility model relates to pedestrian path technical field especially relates to a permeable pavement pedestrian path with increase and ooze and drainage function. This permeable pavement people's footpath with increase and ooze and drainage function is permeable pavement brick layer, coarse sand layer, no sand concrete base course, natural level and joins in marriage sand stone rolling layer and plain soil tamp layer from the top down in proper order, and wherein natural level joins in marriage the grit and rolls the in situ and be equipped with a plurality of drain pipes, is equipped with a plurality of infiltration mouths in the drain pipe, and too much rainwater can pass the infiltration mouth and discharge from the drain pipe. When the conditions such as soil foundation, soil permeability coefficient, underground water level and the like do not meet the regulations of regulations and the rainfall intensity exceeds the permeation quantity and the unit storage capacity, the infiltration increasing and drainage effects of the permeable pavement on rainwater can be enhanced. This permeable pavement structure with increase and ooze and drainage function is whole strong, and the structure is simple and easy, easily constructs, is fit for using widely.

Description

Permeable pavement pedestrian way with permeation increasing and drainage functions

Technical Field

The utility model relates to pedestrian path technical field especially relates to a permeable pavement pedestrian path with increase and ooze and drainage function.

Background

The common method for water permeable pavement in the market at present is that a water permeable pavement structure comprises a surface course, a leveling course, a base course, a cushion course and a soil foundation from top to bottom. The permeable pavement is not good in surface permeation and drainage effect when used as a permeable pavement; the permeable pavement has poor internal permeation and drainage effects

The utility model discloses a pedestrian's footpath of mating formation of permeating water with increase and ooze and drainage function, this pedestrian's footpath of mating formation of permeating water with increase and ooze and drainage function from the top down is permeable pavement brick layer, coarse sand layer, no sand concrete basic unit, natural level in proper order and joins in marriage gravel rolling layer and plain soil tamp layer, wherein natural level joins in marriage the gravel and rolls the in situ and be equipped with a plurality of drain pipes, be equipped with a plurality of infiltration mouths in the drain pipe, too much rainwater can pass the infiltration mouth and discharge from the drain pipe. When the conditions such as soil foundation, soil permeability coefficient, underground water level and the like do not meet the regulations of regulations and the rainfall intensity exceeds the permeation quantity and the unit storage capacity, the infiltration increasing and drainage effects of the permeable pavement on rainwater can be enhanced. This permeable pavement structure with increase and ooze and drainage function is whole strong, and the structure is simple and easy, easily constructs, is fit for using widely.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defect that exists among the background art, the utility model provides a technical scheme that its technical problem adopted is: the utility model provides a permeable pavement pedestrain way with increase and ooze and drainage function, includes plain soil tamped layer and permeable pavement brick layer, permeable pavement pedestrain way from the top down is permeable pavement brick layer, coarse sand layer, no sand concrete base layer, natural level in proper order and joins in marriage gravel rolling layer and plain soil tamped layer, natural level is joined in marriage the gravel and is rolled the in situ and be equipped with a plurality of drain pipes, be equipped with a plurality of infiltration mouths on the drain pipe.

Preferably, the compaction coefficient of the plain soil compaction layer is greater than or equal to 0.93, the natural-grade sand-stone rolling layer is a 300 mm natural-grade sand-stone rolling layer, the coarse sand layer is a 30 mm coarse sand layer, and the thickness of the permeable pavement brick layer is 80 mm.

The utility model relates to a pedestrian's footpath of mating formation permeates water with increase and ooze and drainage function, this pedestrian's footpath of mating formation from the top down of permeating water with increase and ooze and drainage function is permeable pavement brick layer, coarse sand layer, no sand concrete basic unit, natural level is joined in marriage gravel and is rolled layer and plain soil tamped layer in proper order, wherein natural level is joined in marriage the gravel and is rolled the in situ and be equipped with a plurality of drain pipes, be equipped with a plurality of infiltration mouths in the drain pipe, too much rainwater can pass the infiltration mouth and discharge from the drain pipe. When the conditions such as soil foundation, soil permeability coefficient, underground water level and the like do not meet the regulations of regulations and the rainfall intensity exceeds the permeation quantity and the unit storage capacity, the infiltration increasing and drainage effects of the permeable pavement on rainwater can be enhanced. This permeable pavement structure with increase and ooze and drainage function is whole strong, and the structure is simple and easy, easily constructs, is fit for using widely.
