Description

Technical Field

[0001] The utility model belongs to the technical field of subgrade reinforcement, and more specifically, particularly relates to a subgrade reinforcement structure. Background Art

[0002] The subgrade is the load-bearing body of a highway. The highway subgrade is composed of width, height, and slope gradient. Whether the highway subgrade is firm directly affects the service time and lifespan of the highway. During the construction of existing roads, the influence of soil quality determines the construction quality of the later road. However, in alpine regions, the soil quality is affected by temperature and humidity, resulting in volume expansion and contraction, leading to subgrade instability and thus easy cracking of the road surface, which needs to be improved.

[0003] Based on the above, existing reinforcement components are difficult to be spliced during laying, which not only reduces the construction efficiency but also increases the labor cost. Moreover, the soil in alpine regions is prone to subgrade cracking due to frost heaving force, affecting the service life of the road. Summary of the Utility Model

[0004] In order to solve the above technical problems, the embodiment of the present disclosure relates to a subgrade reinforcement structure to solve the problems that the reinforcement components are difficult to be spliced, affecting the efficiency, and the soil in alpine regions is prone to subgrade cracking due to frost heaving force. Through the setting of the assembly structure, it is not only convenient for workers to splice it, accelerating the construction efficiency of subgrade reinforcement and solving the problem of difficult splicing of reinforcement components, but also under the action of the clamping components, enhancing the tensile property of the reinforcement components, ensuring the stability of the connection between the reinforcement components, and improving the service life of the road. By setting the reinforcement components, the crack resistance of the subgrade can be increased through the anti-crack net, preventing the subgrade from cracking due to frost heaving force, and through the setting of the concrete bearing plate, enhancing the bearing effect of the road surface.

[0038] Embodiment 1: As shown in Figure 1 to Figure 6 shown:

[0039] The present utility model provides a subgrade reinforcement structure, including a subgrade layer 1 and an assembly structure 3;

[0040] At the top of the road base layer 1, there is a reinforced bottom frame 201. On both sides of the reinforced bottom frame 201, there are first baffles 205 fixedly connected. At one end of the first baffle 205, there is a second baffle 207. At one end of the first baffle 205, there is an assembly groove 301. At the upper and lower ends of the assembly groove 301, there are connecting slots 3011. Inside the connecting slots 3011, there are moving grooves 3012. Inside the first baffle 205, there is a reset support groove 3021. Between the reset support groove 3021 and the moving groove 3012, there are sliding support holes 302. At the same time, inside the reset support groove 3021, there is a reset spring 3022 installed. Inside the connecting slots 3011, there are locking wedges 303. One end of the locking wedge 303 is fixedly connected with a sliding support rod 3031. At the end of the sliding support rod 3031, there is a fixed convex ring 3032. The fixed convex ring 3032 is fitted and slidably installed inside the reset support groove 3021. On the side of the second baffle 207 close to the first baffle 205, there is a connecting rib 304 fixedly connected. On the connecting rib 304, there is an insertion wedge 3041 fixedly connected. The insertion wedge 3041 is inserted into the connecting slot 3011. And on the insertion wedge 3041, there is a locking wedge groove 3042. At the same time, the locking wedge 303 is clamped inside the locking wedge groove 3042. The two groups of moving grooves 3012 on the first baffle 205 are of opposite structures. Through the reinforced bottom frame 201 and the first baffle 205, they are wrapped around the outside of the road base layer 1. Then, align the second baffle 207 on the other group with the first baffle 205. Then push the second baffle 207 so that the second baffle 207 drives the connecting rib 304 to move. The connecting rib 304 drives the insertion wedge 3041 to be inserted into the connecting slot 3011. Under the setting of the inclined plane, the locking wedge 303 is extruded, so that the locking wedge 303 drives the fixed convex ring 3032 through the sliding support rod 3031 to extrude the reset spring 3022 inside the reset support groove 3021. When the insertion wedge 3041 can no longer extrude the locking wedge 303, the reset spring 3022 is not under pressure. Thus, under the reaction force, it elastically pushes the fixed convex ring 3032 to move. The fixed convex ring 3032 drives the locking wedge 303 to reset and be inserted into the locking wedge groove 3042 through the sliding support rod 3031. Thus, the assembly of the two groups of reinforcement members is completed, facilitating the staff to quickly splice them. Through the setting of the positive and negative locking wedges 303 and the locking wedge grooves 3042, the tensile strength of the reinforcement members is enhanced, ensuring the stability of the connection between the reinforcement members.

[0041] Embodiment 2: On the basis of Embodiment 1, where as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a reinforcement component 2 is provided inside the reinforced bottom frame 201. The reinforcement component 2 includes a chamber 2011 and a first anti-cracking net 202. A chamber 2011 is opened inside the reinforced bottom frame 201, and a first anti-cracking net 202 is laid at the bottom of the chamber 2011. A concrete bearing plate 203 is provided on the top of the first anti-cracking net 202. A second anti-cracking net 2021 is provided on the top of the concrete bearing plate 203. At the same time, a road surface layer 204 is provided on the top of the second anti-cracking net 2021. Support angle blocks 206 are provided on the outer sides of the first baffle 205 and the second baffle 207. An extension convex plate 2061 is fixedly connected to one outer end of the support angle block 206. At the same time, two sets of insertion holes 2062 are respectively opened on the extension convex plate 2061. A limit ground nail 2063 is inserted into the insertion hole 2062. Through the cooperation of the first anti-cracking net 202 and the second anti-cracking net 2021, the anti-cracking performance of the roadbed can be increased, and the roadbed can be prevented from cracking due to frost heaving force. Through the setting of the concrete bearing plate 203, the bearing effect of the road surface is increased. Then, the support angle block 206 is abutted against the outer side of the baffle, and the limit ground nail 2063 is inserted into the ground through the insertion hole 2062, preventing the side collapse of the roadbed soil and ensuring the overall stability of the roadbed.

[0042] Specific usage method and function of this embodiment:

[0043] In this utility model, first, the reinforced bottom frame 201 and the first baffle 205 are wrapped around the outer side of the roadbed layer 1. Then, the second baffle 207 on the other group is aligned with the first baffle 205. Then, the second baffle 207 is pushed to drive the connecting convex strip 304 to move. The connecting convex strip 304 drives the mating wedge block 3041 to be inserted into the connecting slot 3011. Under the setting of the inclined surface, the locking wedge block 303 is extruded, so that the locking wedge block 303 drives the fixed convex ring 3032 to squeeze the return spring 3022 in the return support groove 3021 through the sliding support rod 3031. When the mating wedge block 3041 cannot squeeze the locking wedge block 303, the return spring 3022 is not under pressure, and thus an elastic force is generated under the reaction force to drive the fixed convex ring 3032 to move. The fixed convex ring 3032 drives the locking wedge block 303 to reset and be inserted into the locking wedge groove 3042 through the sliding support rod 3031, thus completing the assembly of the two groups of reinforcement members, facilitating the staff to quickly splice them. Then, the support angle block 206 is abutted against the outer side of the baffle, and the limit ground nail 2063 is inserted into the ground through the insertion hole 2062, preventing the side collapse of the roadbed soil and ensuring the overall stability of the roadbed.
