Description

Technical Field

[0001] This utility model relates to the field of roadbed structure technology, specifically a roadbed structure that can delay deformation and potholes. Background Technology

[0002] The roadbed is the foundation of the track or road surface. It is an earthwork structure formed by excavation or filling. Its core function is to provide stable support for the road surface or track and to transfer loads.

[0003] Currently, there are many types of roadbed structures. For example, a roadbed structure with Chinese patent number CN202421445813.7 that can prevent roadbed softening includes a soil base layer. The soil base layer has an internal anchoring structure for anchoring the soil base layer. A first crushed stone layer is laid on the soil base layer, a lime-soil cushion layer is laid on the first crushed stone layer, and a drainage layer is laid on the lime-soil cushion layer. The drainage layer includes two rows of concrete slopes spaced apart on the lime-soil cushion layer. A waterproof layer is laid in the middle of the upper surface of the lime-soil cushion layer, located between the two rows of concrete slopes. The height of the first layer is lower than that of the concrete slope. A second crushed stone layer is laid on top of the waterproof layer, and the second crushed stone layer is flush with the concrete slope. This subgrade structure, which can prevent subgrade softening, can drain rainwater that seeps into the subgrade, thereby avoiding subgrade softening caused by the subgrade being in a damp state for a long time. At the same time, the maintenance cost is low, and the overall structure has good support. It is less affected by thermal expansion and contraction and humidity, and the drainage layer is not easily damaged. However, in actual use, since the drainage channel of this patent is directly opened under the lime-soil cushion layer, long-term heavy vehicle rolling can easily cause the channel to collapse, which in turn leads to road surface settlement. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model provides a roadbed structure that can delay deformation and potholes, has the advantage of strong stability, and solves the problem of road surface deformation in the patent.

[0005] To achieve the aforementioned goal of high stability, this utility model provides the following technical solution: a roadbed structure capable of delaying deformation and potholes, comprising a soil base layer, a structural layer provided above the soil base layer, the structural layer comprising a crushed stone layer, a lime-soil cushion layer, a concrete layer, a waterproof layer and an asphalt layer, the crushed stone layer, the lime-soil cushion layer, the concrete layer, the waterproof layer and the asphalt layer being laid sequentially above the soil base layer, a drainage mechanism being provided on the asphalt layer, and a reinforcement mechanism being provided between the concrete layer and the soil base layer;

[0006] The reinforcement mechanism includes a first support plate, a second support plate, and reinforcement columns. The first support plate is embedded inside the concrete layer, the second support plate is embedded inside the soil base layer, and several reinforcement columns are arranged between the first support plate and the second support plate.

[0007] Furthermore, both the first support plate and the second support plate are reinforced concrete slabs, and the reinforcing column is a reinforced concrete column.

[0008] Furthermore, the drainage mechanism includes a drainage trough, a filter cover, and a drainage pipe. Several drainage troughs are evenly distributed on the asphalt layer. Each drainage trough is equipped with a filter cover at its top and a drainage pipe extending to the outside of the roadbed structure at its bottom.

[0009] Furthermore, the filter end of each of the filter covers is designed with an inclined plate.

[0010] Furthermore, the surface of the waterproof layer is a geomembrane.

[0011] Furthermore, the reinforcing column is fixedly connected to support plate one and support plate two by welding.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This roadbed structure, which can delay deformation and potholes, has a reinforcement mechanism. When a large vehicle travels on the road surface, the pressure generated by the vehicle is first transmitted to support plate one through the ground. Then, after receiving the pressure, support plate one can distribute it to support plate two through the support of the reinforcement column. Finally, with the support of support plate one, support plate two, reinforcement column and soil base, the stability of the structural layer can be effectively guaranteed, and the road surface deformation can be avoided. It is highly practical.

[0014] 2. This roadbed structure, which can delay deformation and potholes, has a drainage mechanism. When the road surface is eroded by rainwater, the filter cover first performs simple filtration, allowing the water on the road surface to flow into the drainage ditch. Then, the drainage ditch stores the water on the road surface. Finally, the drainage pipe can be connected to the underground sewage pipe, allowing the sewage in the drainage ditch to be discharged quickly. Thus, this mechanism can effectively prevent potholes caused by a large amount of rainwater intruding into the structural layer, and it is highly practical. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment of a roadbed structure that can delay deformation and potholes includes a soil base 1, and a structural layer 2 is provided on top of the soil base 1. The structural layer 2 includes a crushed stone layer 201, a lime-soil cushion layer 202, a concrete layer 203, a waterproof layer 204, and an asphalt layer 205. The crushed stone layer 201, the lime-soil cushion layer 202, the concrete layer 203, the waterproof layer 204, and the asphalt layer 205 are laid sequentially on top of the soil base 1. A drainage mechanism 3 is provided on the asphalt layer 205, and a reinforcement mechanism 4 is provided between the concrete layer 203 and the soil base 1.

[0022] The reinforcement mechanism 4 includes a first support plate 401, a second support plate 402, and reinforcement columns 403. The first support plate 401 is embedded inside the concrete layer 203, and the second support plate 402 is embedded inside the soil base layer 1. Both the first support plate 401 and the second support plate 402 are reinforced concrete slabs. Several reinforcement columns 403 are arranged between the first support plate 401 and the second support plate 402. The reinforcement columns 403 are reinforced concrete columns, and are welded to the first support plate 401 and the second support plate 402. The second support plate 402 is fixedly connected. When a large vehicle drives on the road surface, the pressure generated by the vehicle is first transmitted to the first support plate 401 through the ground. Then, after receiving the pressure, the first support plate 401 can distribute the pressure to the second support plate 402 through the support of the reinforcing column 403. Finally, with the support of the first support plate 401, the second support plate 402, the reinforcing column 403 and the soil base 1, the stability of the structural layer 2 can be effectively guaranteed, and the road surface deformation can be avoided. It is highly practical.

[0023] In the implementation of the case, the drainage mechanism 3 includes a drainage trough 301, a filter cover 302, and a drainage pipe 303. Several drainage troughs 301 are evenly distributed on the asphalt layer 205. Each drainage trough 301 is equipped with a filter cover 302 on its top. The filter end of each filter cover 302 is designed with an inclined plate. Each drainage trough 301 is equipped with a drainage pipe 303 extending to the outside of the roadbed structure at its bottom. When the road surface is eroded by rainwater, the filter cover 302 first performs simple filtration, allowing the water on the road surface to drain into the drainage trough 301. Then, the drainage trough 301 stores the water on the road surface. Finally, the drainage pipe 303 can be connected to the underground sewage pipe, allowing the sewage in the drainage trough 301 to be discharged quickly. Thus, this mechanism can effectively prevent the potholes caused by a large amount of rainwater intruding into the structural layer 2, and it is highly practical.

[0024] In the case implementation, the surface of the waterproof layer 204 is a geomembrane, which is made of high-density polyethylene or polypropylene. It has the characteristics of strong anti-aging properties, acid and alkali resistance, and high isolation properties. This structure can effectively prevent water from seeping into the underlying foundation soil layer, protect the stability of the foundation soil layer, improve the bearing capacity and stability of the roadbed, and extend the service life of the road.

[0025] When implementing this procedure, please follow these steps:

[0026] 1) First, the pressure generated by the vehicle will be transmitted to the support plate 401 through the ground;

[0027] 2) Then, after receiving pressure, the pressure on support plate 1 401 can be distributed to support plate 2 402 through the support of reinforcement column 403;

[0028] 3) Finally, with the support of support plate 1 401, support plate 2 402, reinforcement column 403 and soil base 1, the stability of structural layer 2 can be effectively guaranteed.

[0029] In summary, this roadbed structure, which can delay deformation and potholes, utilizes reinforcement mechanism 4. When a large vehicle travels on the road surface, the pressure generated by the vehicle is first transmitted to support plate 401 through the ground. Then, after receiving the pressure, support plate 401 distributes the pressure to support plate 402 through the support of reinforcement column 403. Finally, with the support of support plate 401, support plate 402, reinforcement column 403, and soil base 1, the stability of structural layer 2 can be effectively guaranteed, preventing road surface deformation. Simultaneously, the drainage mechanism 3 further enhances the stability. When the road surface is eroded by rainwater, the filter cover 302 first performs simple filtration, allowing the water on the road surface to drain into the drainage trough 301. Then, the drainage trough 301 stores the water on the road surface. Finally, the drainage pipe 303 can be connected to the underground sewage pipe, allowing the sewage in the drainage trough 301 to be discharged quickly. Thus, this mechanism can effectively prevent the potholes caused by a large amount of rainwater intruding into the structural layer 2. It is highly practical and solves the problem that the drainage trough of this patent is directly opened under the soil cushion layer, which is prone to collapse due to long-term heavy vehicle rolling, thus causing road subsidence.
