Abstract
The utility model discloses a blind drainage ditch for a highway pavement. The blind drainage ditch for the highway pavement comprises a bituminous pavement, flat stone and paving stone arranged between the bituminous pavement and a green zone, wherein a clearance is arranged between the bituminous pavement and the flat stone along the road; vertical plastic blind tubes are arranged inside the clearance at intervals along the road in the vertical direction; the vertical plastic blind tubes are connected with a transverse plastic blind tube arranged below the bituminous pavement; the transverse plastic blind tube is connected with a ponding well; the ponding well is connected with a water pump in the green zone through a pipeline. An impermeable layer and a reverse osmosis layer are arranged in roadbed pavement, so as to reduce corrosion to a roadbed caused by the moisture, and meanwhile, the vertical plastic blind tubes and the transverse plastic blind tube are also arranged to timely dredge the moisture in the roadbed to the ponding well, so that the moisture in the roadbed is reduced, and the technical problems that the pavement has frost boiling and the like under rolling compaction of a vehicle are solved.
Description
Technical field
The utility model relates to a kind of highway pavement and dredges weeper drain.
Background technology
In highway construction region, when causing groundwater table, the reasons such as precipitation raise, the erosion of the underground water that roadbed can be subject to, the problem of bringing is that, after raise of stage, a large amount of ponding infiltrations, in roadbed, make roadbed be rich in moisture.Vehicle road pavement there will be the situations such as frost boiling after repeatedly rolling, and causes highway hollow, though constantly maintenance always can not be eradicated.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of highway pavement to dredge weeper drain.
For achieving the above object, the utility model adopts following technical proposals:
A kind of highway pavement is dredged weeper drain, comprise flexible pavement, and the riglet stone and the curb that between flexible pavement and greenbelt, are provided with, between described flexible pavement and riglet stone, along road direction, be provided with gap, direction interval, Zhong Yan road, described gap is provided with vertical plastics blind pipe in vertical, the horizontal plastics blind pipe that described vertical plastics blind pipe has with flexible pavement is connected, and described horizontal plastics blind pipe is connected with ponding well, and described ponding well is connected with the water pump in greenbelt by pipeline.
Described flexible pavement is equipped with asphalt surface course, modified emulsifying asphalt sticking layer oil, middle grain bitumen layer, geotextiles, coarse grain bitumen layer, cobble brickbat layer from top to bottom successively, described cobble brickbat layer below is former soil layer, described horizontal plastics blind pipe is arranged in cobble brickbat layer, and described ponding well location is among cobble brickbat layer and former soil layer.
By gap is set along road direction between flexible pavement and riglet stone, after precipitation, by flexible pavement central authorities than the high structure that is convex surface in edge, the water on road surface converges to gap rapidly and the vertical plastics blind pipe being provided with by vertical, through horizontal plastics blind pipe, be received in the ponding well that is arranged on deeply cobble brickbat layer and former soil layer again, in addition, on the laying structure of flexible pavement, take modified emulsifying asphalt sticking layer oil and geotextiles can realize waterproof infiltration and counter-infiltration, the precipitation major part on road surface is collected in ponding well like this, like this, roadbed can be avoided directly being corroded by water, the water of collecting can be used for watering greenbelt future by water pump, if hypervolia, also can utilize pump truck in time water to be extracted out and transferred to the region away from roadbed, thereby protection roadbed, make highway pavement that the bad problems such as frost boiling not occur.
Modified emulsifying asphalt sticking layer oil and geotextiles can reduce road surface precipitation and be penetrated in roadbed, after raising, groundwater table also can realize counter-infiltration, in addition, though laterally plastics blind pipe is horizontal, but also can there is certain gradient, moisture in cobble brickbat layer can be dredged in ponding well timely like this, ponding well can be communicated with each other, along the direction on road, be arranged in successively the below of greenbelt, can when building, longitudinally form certain gradient, become the structure of similar karez, become a subterranean stream, in time the underflow of enrichment is gone out, the degree of drying that keeps rich pool roadbed.
Described asphalt surface course comprises the rubber powder of interpolation.Because mulseal sticking layer oil and geotextiles can prevent the precipitation infiltration on road surface, during precipitation, when water trickles to gap, temporarily on road surface form Shuifu County's collection period, the rubber powder of interpolation is conducive to improve the earth-grasping force of driving vehicle, and control is skidded etc.
The thickness of described middle grain bitumen layer is 60mm～100mm.Described is the thickness 60mm～100mm of coarse grain bitumen layer.The thickness of described cobble brickbat layer is 500mm～1000mm.Like this can be suitable increase roadbed, and then raise highway pavement, make waterline away from road surface, keep road conditions good.
The utility model arranges impermeable layer and the erosion to roadbed with minimizing moisture of counter-infiltration layer in roadbed is laid, vertical plastics blind pipe is also set simultaneously, laterally plastics blind pipe is dredged the moisture in roadbed in ponding well in time, thereby reduced moisture content in roadbed, avoided road surface at vehicle, to roll the technical problems such as lower appearance frost boiling.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1. asphalt surface course, 2. modified emulsifying asphalt sticking layer oil, 3. in grain bitumen layer, 4. geotextiles, 5. coarse grain bitumen layer, 6. cobble brickbat layer, 7. vertical plastics blind pipe, 8. riglet stone, 9. curb, 10. water pump, 11. ponding wells, 12. former soil layers, 13. horizontal plastics blind pipes.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.Just as skilled in the art will understand, these descriptions are exemplary, only for explaining the utility model, and are not to restriction of the present utility model.In the following description, omit the description to known configurations and technology, to avoid unnecessarily obscuring concept of the present utility model.In each accompanying drawing, identical element adopts similar Reference numeral to represent.For the sake of clarity, the various piece in accompanying drawing is not drawn in proportion.
In Fig. 1, a kind of embodiment is provided, a kind of highway pavement is dredged weeper drain, comprise flexible pavement, and the riglet stone 8 being provided with between flexible pavement and greenbelt and curb 9, between described flexible pavement and riglet stone 8, along road direction, be provided with gap, direction interval, Zhong Yan road, described gap is provided with vertical plastics blind pipe 7 in vertical, the horizontal plastics blind pipe 13 that described vertical plastics blind pipe 7 has with flexible pavement is connected, described horizontal plastics blind pipe 13 is connected with ponding well, and described ponding well 11 is connected with the water pump 10 in greenbelt by pipeline.
