Abstract
The utility model discloses a kind of special discharge structure in walking road surface, include porous pavement layer, fine sand levelling blanket, stone grain pervious bed, coarse sand permeable layer and basic unit successively from top to down, the basic unit is provided with gully, in the gully in be equipped with drainage pipeline.This practicality passes through novel water permeable supercrust, fine sand levelling blanket, stone grain pervious bed and coarse sand permeable layer, road surface moisture is dredged to underground, and water is excluded to dredge by the drainage pipeline in basic unit, so that road surface is not likely to produce rainwash, the generation of urban waterlogging can be effectively prevented, the discharge pressure of municipal drainage facility can be alleviated.The utility model is widely used in road drainage technical field as a kind of special discharge structure in walking road surface.
Description
Technical field
It the utility model is related to road drainage technical field, more particularly to a kind of special discharge structure in walking road surface.
Background technology
In recent years, the rainfall of China some areas is concentrated, and the rainy weather of this concentration is made to the drainage system of urban pavement
Into huge pressure.Especially seem to be concentrated in Beijing, Shenzhen, Wuhan, these rainfall of Changsha, the high city of surface sealing degree
In, if top drainage work(system can not provide enough displacement, rainwash will be caused in the case of especially big rainfall, some
Low laying areas may there is also the condition of a disasters such as urban waterlogging.Therefore, the roadnet with excellent drain function becomes at present
The hot fields of research.
With the construction of urban road and city trees and shrubs, pavement, square, park, parking lot, cell etc. need to lay stone
The walking road surface of brick increases sharply.In general, tile work road uses is made based on the materials such as cement, laterite, Sha Ji, ceramics
Variously-shaped specification road brick for material as laying top layer, sub-surface is used as using materials such as cement, local soil.It is this
The advantages of typical two-layer road surface is that cost is low, laying is simple, but simultaneously there is also because of impeded drainage, permeable bad and draw
The shortcomings that the problems such as playing rainwash and soil compaction.
The road of water-permeable brick laying, there is small gap between brick and brick, there is permeable space inside brick body.
Due to the presence of these good discharge structures so that during lasting heavy showers, road surface is not in rainwash phenomenon.
But if only carrying out draining using water-permeable brick, and ignore the drainage performance of sub-surface, using the low cement of permeability or
Soil is as sub-surface, the problems such as equally causing surface gathered water, rainwash at heavy showers day.Therefore, in rainfall collection
In area, using water-permeable brick and coordinate the good underlying surface of drainage effect, have great significance.
Utility model content
In order to solve the above-mentioned technical problem, it is special to be to provide a kind of good walking road surface of drainage effect for the purpose of this utility model
Use discharge structure.
Technical scheme is used by the utility model：A kind of special discharge structure in walking road surface, is wrapped successively from top to down
Porous pavement layer, fine sand levelling blanket, stone grain pervious bed, coarse sand permeable layer and basic unit are included, the basic unit is provided with gully, the ditch
Drainage pipeline is equipped with gully.
Further, some vias are arranged at intervals with the drainage pipeline.
Further, axial direction of the via along the drainage pipeline is arranged in a linear.
Further, the via is set down.
Further, the drainage pipeline is PVC drain pipe.
Further, the porous pavement layer is laid by permeable pavement brick.
Further, the fine sand levelling blanket uses fine sand that particle diameter is 0.2 to 2mm as raw material, laying depth be 5 to
10cm。
Further, the stone grain pervious bed uses rubble grain that particle diameter is 1 to 2cm as raw material, laying depth be 15 to
50cm。
Further, coarse sand permeable layer uses coarse sand that particle diameter is 2 to 10mm laying depth is 15 to 30cm as raw material.
The beneficial effects of the utility model are：The utility model passes through porous pavement layer, fine sand levelling blanket, stone grain pervious bed
With coarse sand permeable layer, road surface moisture is dredged to underground, and water is excluded to dredge by the drainage pipeline in basic unit so that road surface
Rainwash is not likely to produce, can effectively prevent the generation of urban waterlogging, the discharge pressure of municipal drainage facility can be alleviated.
Brief description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is structure sectional view of the present utility model；
Fig. 2 is the structural representation of the drainage pipeline in the utility model.
Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.
As shown in figure 1, a kind of special discharge structure in walking road surface, includes porous pavement layer 1, fine sand is put down successively from top to down
Flood 2, stone grain pervious bed 3, coarse sand permeable layer 4 and basic unit 5, the basic unit 5 are provided with gully 6, in the gully 6 in be equipped with
Drainage pipeline 8, the pipe of drainage pipeline 8 are connected with municipal drainage facility, and the surrounding of drainage pipeline 8 fills the gravel particle of 1-2cm particle diameters.
In the present embodiment, the porous pavement layer 1 is laid by permeable pavement brick；The fine sand levelling blanket 2 uses particle diameter
For 0.2 to 2mm fine sand as raw material, laying depth is 5 to 10cm；The stone grain pervious bed 3 uses particle diameter for 1 to 2cm's
For rubble grain as raw material, laying depth is 15 to 50cm；It is 2 to 10mm coarse sand as raw material that coarse sand permeable layer 4, which uses particle diameter,
Laying depth is 15 to 30cm.
By porous pavement layer, fine sand levelling blanket, stone grain pervious bed and coarse sand permeable layer, road surface moisture is dredged to underground
Lead, and water is excluded to dredge by the drainage pipeline in basic unit so that road surface is not likely to produce rainwash, can effectively prevent city
The generation of city's waterlogging, the discharge pressure of municipal drainage facility can be alleviated.Wherein fine sand levelling blanket, stone grain pervious bed and coarse sand ooze
Water layer, not only can also have very high intensity so that pedestrian-way is not easy to collapse with permeable, water purification.
As shown in Fig. 2 a kind of drainage pipeline applied to the special discharge structure in walking road surface, it is spaced and sets on the drainage pipeline
Some vias 9 are equipped with, axial direction of the via 9 along the drainage pipeline is arranged in a linear.The via 9 is set down.Make
It is PVC drain pipe for drainage pipeline described in preferred embodiment.Via 9 is set, is advantageous to the moisture permeated downwards, passes through row
Waterpipe is dredged, and the via 9 is set towards the lower section in gully 6, and when water is few, moisture also may penetrate into drainage pipeline,
Dredged by drainage pipeline.
Above is preferably implement to be illustrated to of the present utility model, but the invention is not limited to the reality
Example is applied, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Shape or replacement, these equivalent deformations or replacement are all contained in the application claim limited range.
