Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and more specifically, to a novel roadbed and pavement crack-resistant structure. Background Art

[0002] "Roads" refers to highways, urban roads, and places within the jurisdiction of an organization that allow public motor vehicle traffic, including squares, public parking lots, and other places used for public passage.

[0003] For example, the publication number CN216074573U discloses a crack-resistant roadbed and pavement structure, comprising at least one pair of retaining walls, wherein a roadbed, a stabilizing layer, a waterproof layer, an asphalt base layer, and an asphalt surface layer are sequentially arranged between the pair of retaining walls from bottom to top; a cavity is provided between the stabilizing layer and the waterproof layer, and an earthquake-resistant structure is connected to the cavity via reinforcing ribs; the earthquake-resistant structure comprises wavy upper and lower stress-bearing plates, wherein a plurality of elastic cylindrical tubes are provided between the upper and lower stress-bearing plates, and a buffer spring is connected between each of the elastic cylindrical tubes; a protrusion is integrally formed on the inner side of the retaining wall, and one end of the protrusion extends into the upper and lower stress-bearing plates and is connected to the elastic cylindrical tube. This solves the problem that the road surface in the existing road structure is still prone to cracking due to the long-term rolling of wheels due to the lack of a corresponding earthquake-resistant structure, which seriously affects the service life of the road structure.

[0004] As can be seen from the above-mentioned publicly available plans, the roadbed is currently mostly laid by directly pouring concrete. The concrete is not protective enough and has poor crack resistance. After a long period of use, cracks are likely to appear on the road surface, which will affect the road's performance and service life. At the same time, the road is also prone to collapse after a long period of use, which will also affect its use. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of roadbed and pavement anti-cracking structure to solve the problems of road crack resistance and collapse resistance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel roadbed and pavement crack-resistant structure, comprising a roadbed, a left retaining wall fixedly installed on the left side of the roadbed, a right retaining wall fixedly installed on the right side of the roadbed, a layer of lime-soil fixedly laid on the upper end of the roadbed, a layer of crushed stone fixedly laid on the upper end of the lime-soil layer, a cement layer fixedly laid on the upper end of the crushed stone layer, multiple vertical reinforcing bars fixedly inserted on the upper end of the roadbed, multiple left short reinforcing bars fixedly installed on the right side of the left retaining wall, multiple right short reinforcing bars fixedly installed on the left side of the right retaining wall, a reinforcing mesh fixedly laid on the upper end of the cement layer, a waterproof layer fixedly laid on the upper end of the reinforcing mesh, an asphalt base layer fixedly laid on the upper end of the waterproof layer, and an asphalt intermediate layer fixedly laid on the upper end of the asphalt base layer. A crack-resistant mesh is fixedly laid on the upper end of the asphalt intermediate layer, and a modified asphalt pavement layer is fixedly laid on the upper end of the crack-resistant mesh. The installation of multiple vertical bars increases the strength of the crushed stone layer, cement layer, and vertical bars. The reinforcing mesh at the upper end of the vertical bars reinforces and pulls the cement layer and waterproof layer to prevent cracks, thereby preventing cracks in other layers. Moreover, the installation of the crack-resistant mesh prevents cracks in the asphalt intermediate layer and modified asphalt pavement layer, thereby increasing the crack resistance of the entire road, increasing the road's performance and service life. At the same time, the installation of left and right short bars and left and right long bars respectively reinforces the road and pulls between layers to prevent movement and collapse. The installation of the lime-soil layer, crushed stone layer, and cement layer also plays a role in reinforcement and preventing collapse.

[0007] Preferably, the left retaining wall and the right retaining wall have the same height and thickness, and the thickness of the gravel layer is greater than that of the ash soil layer. By setting the left retaining wall and the right retaining wall, the left and right sides of each layer are respectively blocked and limited.

[0008] Preferably, the thickness of the crushed stone layer is greater than that of the cement layer, the vertical reinforcement is fixed through the lime soil layer, the crushed stone layer and the cement layer, and the left short reinforcement is fixedly inserted into the left side of the lime soil layer, the crushed stone layer and the cement layer.

[0009] Preferably, the right short bar is fixedly inserted into the right side of the lime-soil layer, the gravel layer and the cement layer, and the lower end of the reinforcing mesh is fixedly connected to the upper end of the vertical bar.

[0010] Preferably, a plurality of left long reinforcements are fixedly provided on the upper right end of the left retaining wall, and a plurality of right long reinforcements are fixedly provided on the upper left end of the right retaining wall, and the left long reinforcements and the right long reinforcements are fixedly inserted into the left and right ends of the asphalt bottom layer and the asphalt middle layer respectively.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) The utility model increases the firmness of the gravel layer, cement layer and vertical reinforcement by setting a plurality of vertical reinforcements, and a reinforcement net is set at the upper end of the vertical reinforcement to reinforce and pull the cement layer and the waterproof layer to avoid cracks, thereby avoiding cracks in other layers. Moreover, by setting the anti-cracking net, the asphalt middle layer and the modified asphalt pavement layer are prevented from cracking, thereby increasing the anti-cracking effect of the entire road, and increasing the road's use effect and service life.

[0013] (2) The utility model reinforces the road by setting the left short reinforcement and the right short reinforcement, and the left long reinforcement and the right long reinforcement, respectively, pulling the layers to prevent movement and collapse. In addition, the utility model also reinforces and prevents collapse by setting the ash soil layer, gravel layer and cement layer. Attached Figure Description
