A kind of road edge drainage system structure
The utility model relates to road drainage technical field more particularly to a kind of road edge drainage system structures.
With the rapid development of our national economy, car ownership in the quickening of urbanization process and China's city scope
Increase, requirement of the people to indexs such as the grades, speed, width of urban road is higher and higher, outside city expressway or city
The roads such as loop wire have more strict requirements to these indexs, and higher standard path proposes the draining of urban road
Higher requirement.Previous road drainage system is asked since the problem of construction and material all can't resolve further serious draining
Topic, needs a large amount of cost to be safeguarded and repaired.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of road edge drainage system is provided
Structure, the structure can drain rapidly the Free water of road delay, be suitable for the small road of base's water penetration, and structure is simple, construction
It is convenient.
A kind of road edge drainage system structure that in order to achieve the above purposes, the technical solution adopted by the utility model is:, packet
Blinding layer, road basis, road deck, collecting gutter, embankment, road shoulder, collector pipe, outlet pipe are included；On the blinding layer
Build has road basic；The road basis is impermeable stratum concrete foundation layer；Building on the basis of the road has road surface
Layer；The collecting gutter is that ditch, collecting gutter bottom surface fitting and base are collected in the infiltration built in road basis and road deck two sides
Plinth bed course top surface；The embankment is the trapezoidal concrete component built in collecting gutter two sides, which flushes with collecting gutter；
The road shoulder is the concrete block piece built on the embankment top surface of road deck two sides；The collecting gutter is arranged in bottom centre
There is collector pipe, which is perforated plastic pipe；The collector pipe builds lateral outlet pipe together, the water outlet every a distance
Pipe is through embankment out.
Preferably, the road basis and road deck are tilted down from road-center to two side directions, slope is
Preferably, the collecting gutter and collector pipe are all outer to wrap up in one layer of anti-filter nonwoven fabric layer.
The beneficial effects of the utility model are: the structure can rapidly drainage pavement surface infiltration, be suitable for level of ground water compared with
Height has spring or has the road of interim backwater, and structure is simple, easy for construction.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is road edge drainage system structural schematic diagram.
Wherein: 1 is basic bed course, and 2 be road basis, and 3 be road deck, and 4 be collecting gutter, and 5 be embankment, and 6 be road shoulder, 7
It is outlet pipe for collector pipe, 8.
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of road edge drainage system structure, includes blinding layer 1, road basis 2, road deck
3, collecting gutter 4, embankment 5, road shoulder 6, collector pipe 7, outlet pipe 8；Building on the blinding layer 1 has road basis 2；The road
Basis 2 is impermeable stratum concrete foundation layer；Building on the road basis 2 has road deck 3；The collecting gutter 4 is to build
Ditch, 4 bottom surface of collecting gutter fitting and 1 top surface of blinding layer are collected in infiltration in road basis 2 and 3 two sides of road deck；It is described
Embankment 5 is the trapezoidal concrete component built in 4 two sides of collecting gutter, which flushes with collecting gutter 4；The road shoulder 6 is
Build the concrete block piece on 5 top surface of embankment of 3 two sides of road deck；The collecting gutter 4 is provided in bottom centre to catchment
Pipe 7, the collector pipe 7 are perforated plastic pipe；The collector pipe 7 builds lateral outlet pipe 8 together, the outlet pipe every a distance
8 through embankment 5 out.
When it is implemented, the road basis 2 and road deck 3 are tilted down from road-center to two side directions, slope
It is 3%.
When it is implemented, the collecting gutter 4 and collector pipe 7 are all outer to wrap up in one layer of anti-filter nonwoven fabric layer.
When practice of construction, the moisture in pavement structure is penetrated into, vertical seepage flow is first passed through and enters porous base course 2, then by cross
Enter the collector pipe with holes 7 in trackside collecting gutter 4 to seepage flow, then is led to by 8 row of lateral outlet pipe of laying spaced apart
Neighbouring catch-basin or rainwater inspection shaft, is discharged by subgrade drainage system.
