Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, an asphalt concrete road structure, including road layer structure and the drainage structures who sets up in road layer structure, road layer structure includes basic unit 1, impervious barrier 2, metalling 3, filter layer 4 and infiltration road surface course 5 that from the bottom up laid in proper order, and the car travels on infiltration road surface course 5.
The base layer 1 can be paved on an original soil base layer by adopting fine broken stones or slag so as to enhance the stability of the whole pavement structure; the side of the base layer 1 close to the impermeable layer 2 is corrugated, so that the water permeating downwards is gathered at the bottom of the valley.
The water seepage road surface layer 5 can be formed by paving water seepage asphalt, so that accumulated water on the road surface is guaranteed to seep downwards while the automobile runs, and the accumulated water on the road surface is reduced.
The filter layer 4 comprises a pre-filter layer 41 and a final filter layer 42, the pre-filter layer 41 is laid on the upper side of the final filter layer 42, the pre-filter layer 41 can be laid by a graded sand gravel layer, and the final filter layer 42 can be laid by water-permeable geotextile, so that accumulated water seeped from the water-permeable pavement layer 5 is ensured to continuously seep downwards; in addition, it can prevent relatively that the fine sand that oozes down from the space in the infiltration road surface layer 5 continues to move downwards, and in the long run, guarantee relatively that whole road surface structure infiltration effect is preferred.
The crushed stone layer 3 can relatively enhance the stability of the whole pavement structure.
The impermeable layer 2 can adopt waterproof geotextile to prevent water permeating from the pavement from eroding the base layer 1 for a long time to cause instability of the roadbed.
Referring to fig. 2 and 3, the drainage structure comprises a plurality of drainage blind pipes 6 which are pre-arranged in the gravel layer 3 and drainage channels 8 which are arranged along the length direction of the road surface.
The drainage blind pipe 6 has better surface water seepage capability and internal water through capability, can discharge water infiltrated from the road surface in time, and ensures better integral drainage effect; in addition, the road surface drainage structure has better pressure resistance, deformation adapting capacity and chemical inertness, and the service life of the road surface drainage structure can be prolonged relatively, so that the relative long-term property of the drainage effect of the road surface drainage structure is ensured.
The drainage blind pipe 6 is arranged, so that the influence of the relative reduction of the drainage rate caused by the tamping of the pavement due to the long-term use of the pavement can be reduced, and the long-term better drainage effect is ensured.
The drainage blind pipe 6 is arranged along the width direction of the road surface and communicated with a drainage channel 8 so as to drain accumulated water in the road surface structure in time.
The drainage blind pipe 6 is obliquely arranged along the width direction of the pavement and is lower close to one end of the drainage channel 8, so that water in the drainage blind pipe 6 is drained in an accelerated manner, and the drainage effect is better; the end, far away from the drainage channel 8, of the drainage blind pipe 6 is of a closed structure to form a solid structure, so that the end opening part of the drainage blind pipe can be prevented from being damaged due to the pressure effect, the compression strength of the end part of the drainage blind pipe is enhanced, and the using effect is better.
The lower end of the drainage blind pipe 6 is higher than the bottom of the drainage channel 8 so as to prevent water in the drainage channel 8 from flowing back to the drainage blind pipe 6.
The drainage blind pipes 6 are positioned at the wave troughs, so that water which downwards permeates and gathers at the wave troughs of the base layer 1 can more quickly permeate into the drainage blind pipes 6, and the drainage efficiency is higher.
Referring to fig. 2, the drainage channels 8 are provided on both sides of the road surface in the width direction and communicate with a municipal drainage system to drain accumulated water in time. The drainage channel 8 is of an upper opening structure and penetrates through the water seepage path surface layer 5, and a plurality of rain grates 81 are laid at the upper opening of the drainage channel 8, so that when surface water directly flows into the drainage channel 8, the probability that surface garbage enters the drainage channel 8 is reduced to a certain extent.
Referring to fig. 3, a protective pipe 7 is wrapped outside the drainage blind pipe 6 to protect the drainage blind pipe 6 and prevent the broken stone from directly contacting with the drainage blind pipe and damaging the drainage blind pipe; the protective tube 7 can be made of steel materials, so that the protective and pressure-resistant effects are enhanced.
In order to make water penetrate into the drainage blind pipe 6, a plurality of water seepage holes 71 are arranged on the protective pipe.
In order to facilitate the installation of the drainage blind pipe 6 into the protective pipe 7 by a constructor, the protective pipe 7 is equally divided into two sub-pipes which are mutually fixed through bolts along the axis direction.
The inner wall of the protective pipe 7 is integrally formed with a plurality of reinforcing ribs 72 along the axial direction thereof, so that the compressive strength of the protective pipe 7 is enhanced, the service life of the protective pipe is prolonged, and the long-term performance of the whole drainage structure is ensured; the side of the reinforcing rib 72 facing away from the protective tube 7 abuts against the blind drain pipe 6, so that the blind drain pipe 6 is fixed relative thereto.
The outside cladding of pillar 7 has infiltration layer 73, and infiltration layer 73 can adopt the infiltration geotechnological cloth, when guaranteeing that water infiltration gets into pillar 7, prevents that the fine sand in the metalling 3 from blockking up the infiltration hole 71 on the pillar 7.
One end of the protective pipe 7 close to the drainage channel 8 is in threaded connection with a protective blocking cover 74, so that possible animals and plants in the drainage channel 8 are prevented from entering the protective pipe 7 or the drainage blind pipe 6 and blocking the protective pipe 7 or the drainage blind pipe 6, and the problem of poor drainage effect is solved.
A plurality of drainage holes 741 are opened in the protective cover 74 to drain water in the protection pipe 7 or the drainage blind 6.
The implementation principle of the embodiment is as follows:
a base layer 1, a water-impermeable layer 2, a rubble layer 3, a filter layer 4 and a water seepage surface layer 5 are sequentially paved upwards on the original soil foundation; before the gravel layer 3 is laid, after the impervious layer 2 is laid, a protective pipe 7 (the drainage blind pipe 6 is installed in the protective pipe 7) is arranged at the valley bottom of the base layer 1; at the same time, drainage channels 8 leading to municipal drainage systems are dug on both sides of the road along its length.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
