Description

Technical Field

[0001] This utility model relates to the field of asphalt road technology, and more specifically, to a stable drainage asphalt road. Background Technology

[0002] In its literal sense, a road is an infrastructure that provides passage for various trackless vehicles and pedestrians. Based on its usage characteristics, roads are classified into highways, urban roads, rural roads, factory and mining roads, forestry roads, and school roads, etc.

[0003] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors. Many properties of a road affect its normal use, one of which is drainage performance. Traditional asphalt pavement usually does not have good drainage performance, so this type of pavement is prone to water accumulation. The accumulated water not only easily causes water to splash when vehicles pass by, but also easily leads to longer braking distances during braking, increasing the risk of driving. Therefore, a structure is designed to solve the problem of poor drainage performance in some traditional asphalt pavements.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stable drainage asphalt road.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stable drainage asphalt road, comprising symmetrically arranged retaining walls and a road body located between two retaining walls, wherein a water guiding part is provided at the joint between the road body and the retaining walls for guiding water on the top surface of the road body to flow vertically downward, and a plurality of drainage pipes are arrayed on the retaining walls, one end of the drainage pipes being connected to the water guiding part, and the other end of the drainage pipes extending out of the retaining walls along the thickness direction of the retaining walls.

[0007] The present invention is further configured such that the water guiding part includes a rubber waterproof layer, a rectangular plastic blind drain and asphalt-fiber filler arranged sequentially from bottom to top.

[0008] The present invention is further configured such that the opening of the drain pipe is located above the rubber waterproof layer and directly opposite the rectangular plastic blind ditch.

[0009] The present invention is further configured such that the road body includes, from bottom to top, a leveling subgrade layer, a gravel subgrade layer, a foamed concrete layer and a breathable asphalt layer.

[0010] The present invention is further provided with waterproof geotextile at the joints between the breathable asphalt layer and the foamed concrete layer, and at the joints between the foamed concrete layer and the rectangular plastic blind drain.

[0011] The present invention is further configured such that the asphalt-fiber filling is located at the joint between the breathable asphalt layer and the retaining wall, and at the joint between the breathable asphalt layer and the rectangular plastic blind drain.

[0012] The present invention is further configured such that: wire mesh is embedded in the foamed concrete layer near the top and bottom sides, and the width of the rubber waterproof layer is greater than the sum of the thickness of the rectangular plastic blind drain and the waterproof geotextile.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The water guide section can stably drain water from the top surface of the road body, allowing the water to be steadily drained to the drainage pipe and then to the outside of the overall structure. This reduces the probability of water accumulation on the top surface of the road body and thus reduces the impact of water accumulation on the overall structure during use.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A type of stable drainage asphalt road, such as Figures 1-3As shown, the structure includes symmetrically arranged retaining walls 1 and a road body located between the two retaining walls 1. The retaining walls 1 are used to provide stable support for the road body, ensuring that the structure as a whole can stably function as a road. At the joint between the road body and the retaining walls 1, there are water guides to guide water from the top surface of the road body to flow vertically downwards. Several drainage pipes 2 are arrayed on the retaining walls 1. One end of the drainage pipe 2 is connected to the water guide, and the other end of the drainage pipe 2 extends out of the retaining wall 1 along its thickness direction. The drainage pipes 2 are made of PVC pipes and are installed at intervals of two meters. Under the action of the water guides, the water accumulated on the top surface of the road body can be stably drained to the drainage pipes 2, and then drained to the outside of the structure, reducing the probability of water accumulation on the top surface of the road body and thus reducing the impact of water accumulation on the overall use of the structure.

[0021] like Figures 1-3 As shown, the water guiding section includes a rubber waterproof layer 3, a rectangular plastic blind drain 4, and an asphalt-fiber filler 5 arranged sequentially from bottom to top. The gaps in the asphalt-fiber filler 5 and the rectangular plastic blind drain 4 create a capillary structure, allowing water accumulating on the road surface to flow steadily across the asphalt-fiber filler 5 and the rectangular plastic blind drain 4 along these gaps to the rubber waterproof layer 3. The rubber waterproof layer 3 acts as a barrier, slowing down the process of rainwater crossing it. The inlet of the drainage pipe 2 is located above the rubber waterproof layer 3 and directly opposite the rectangular plastic blind drain 4. This arrangement ensures that rainwater flowing to the inlet of the drainage pipe 2 can stably enter the drainage pipe 2 from its inlet and, guided by the drainage pipe 2, flow steadily from the side closest to the road body to the other side of the retaining wall 1. This ensures the overall drainage function of the structure is stably realized, reducing the probability of water accumulation on the road surface and the impact of water accumulation on traffic.

[0022] like Figures 1-3As shown, the road body includes, from bottom to top, a leveling subgrade layer 6, a gravel subgrade layer 7, a foamed concrete layer 8, and a breathable asphalt layer 9. These layers are laid sequentially. The good permeability of the breathable asphalt layer 9 enhances the overall permeability of the structure, allowing water accumulating on top of the layer to flow more effectively through its internal gaps, reducing the probability of water accumulation on its surface. Waterproof geotextile 10 is installed at the joints between the breathable asphalt layer 9 and the foamed concrete layer 8, as well as at the joints between the foamed concrete layer 8 and the rectangular plastic blind drain 4. Water flowing over the breathable asphalt layer 9 can then flow stably along the surface of the waterproof geotextile 10. The waterproof geotextile 10 is attached to the top and side walls of the foamed concrete layer 8. Utilizing the good waterproof stability of the geotextile 10, the waterproof performance of the top and sides of the foamed concrete layer 8 is enhanced. Under the drainage effect of the waterproof geotextile 10, water on the geotextile 10 can flow better to the water-conducting part, allowing the water-conducting part to better guide the water to the drainage pipe 2 and discharge it through the drainage pipe 2. The asphalt-fiber filler 5 is located at the joint between the permeable asphalt layer 9 and the retaining wall 1, and at the joint between the permeable asphalt layer 9 and the rectangular plastic blind drain 4. This allows for gaps between the permeable asphalt layer 9 and the retaining wall 1 to allow water to flow through. The capillary structure formed by the asphalt-fiber filler 5 can better achieve stable drainage of water flowing to this location, making the water-conducting function of the water-conducting part more stable.

[0023] like Figures 1-3 As shown, wire mesh 11 is embedded in the foamed concrete layer 8 near the top and bottom sides. The wire mesh 11 embedded in the foamed concrete layer 8 can enhance the overall structural strength of the foamed concrete layer 8, reduce the probability of cracking during use, and make the overall structure more stable. The width of the rubber waterproof layer 3 is greater than the sum of the thickness of the rectangular plastic blind drain 4 and the waterproof geotextile 10. This setting ensures that the rubber waterproof layer 3 can stably block the rainwater flowing down along the rectangular plastic blind drain 4, so that the water guided to the rubber waterproof layer 3 by the water guide can be stably discharged to the outside of the structure by the drainage pipe 2, reducing the amount of water accumulation inside the structure, and allowing the water accumulation on the top surface of the road body to be better discharged to the drainage pipe 2, making the overall drainage stability of the structure better.

All technical solutions falling within the scope of this utility model's concept are protected.
