Description
Technical Field
[0001] This utility model relates to the field of roadbed reinforcement technology, and in particular to a roadbed protection and reinforcement structure. Background Technology
[0002] The roadbed refers to the foundation structure laid beneath the road surface. It is an important component of highway engineering, directly bearing vehicle loads and transferring them to the underlying soil layer, while providing stable support for the road surface. During road construction, after the roadbed construction is completed, reinforcement structures are needed to strengthen it. These reinforcement structures can effectively prevent the roadbed from sliding and collapsing.
[0003] In the traditional process of using roadbed reinforcement structures, the reinforcement plate is first placed outside the roadbed that needs to be reinforced, then the reinforcement plate is attached to the roadbed, and finally the reinforcement plate is fixed with anchor bolts to complete the roadbed reinforcement operation.
[0004] Although traditional reinforcement structures can meet the basic reinforcement requirements of roadbeds, their fixing method mainly relies on anchor bolts inserted into the ground at a single point. This method has a small contact area with the roadbed material. Especially when the geological conditions are poor (such as soft soil or loose soil), the anchoring force of the anchor bolts is often difficult to guarantee, leading to the loosening or failure of the reinforcement plate, thereby weakening the overall effect of roadbed reinforcement. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a roadbed protection and reinforcement structure, which aims to improve the existing technology where the fixing method mainly relies on the single-point insertion of anchor rods into the ground. This method has a small contact area with the roadbed material, and the anchoring force of the anchor rods is often difficult to guarantee, especially when the geological conditions are poor (such as soft soil or loose soil).
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A roadbed protection and reinforcement structure includes a first reinforcement plate, a second reinforcement plate is provided on the outer right side of the first reinforcement plate, both the first reinforcement plate and the second reinforcement plate are provided with disassembly and assembly components, and both the first reinforcement plate and the second reinforcement plate are provided with fixing components.
[0008] The fixing assembly includes a fixing cone, with triangular blocks fixedly connected to both sides of the lower part of the fixing cone, a limit plate fixedly connected to the upper part of the fixing cone, a lead screw threaded inside the fixing cone, a knob fixedly connected to the top of the lead screw, a conical block fixedly connected to the bottom of the lead screw, fixing rods fixedly connected to both sides of the inside of the fixing cone, movable plates slidably connected to both sides of the outer of the two fixing rods, springs sleeved on both sides of the outer of the two fixing rods, and extension blocks fixedly connected to the outer of both movable plates.
[0009] Furthermore, the disassembly and assembly assembly includes two protrusions, which are fixedly connected to the right side of the first reinforcing plate and disposed inside the second reinforcing plate. Pins are inserted into both sides of the interior of the second reinforcing plate.
[0010] Furthermore, the reinforcing plate II has through holes on both sides inside, and the two pins are slidably connected inside the two through holes.
[0011] Furthermore, two through holes are provided on both sides of the outer side of the fixed cone, and the two extension blocks are slidably connected inside the two through holes.
[0012] Furthermore, both the first reinforcing plate and the second reinforcing plate have mounting holes inside, and the two fixing cones are slidably connected inside the two mounting holes.
[0013] Furthermore, the reinforcing plate has insertion holes on both sides of its outer surface, and the two protrusions are inserted into the two insertion holes.
[0014] Furthermore, each of the two protrusions has a positioning hole inside, and the two pins are threadedly connected to the two positioning holes.
[0015] Furthermore, both the first and second reinforcing plates have diamond-shaped grids around their interior perimeter, and both the first and second reinforcing plates have drainage grooves on their lower sides.
[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, when reinforcing the roadbed, firstly, reinforcing plate one and reinforcing plate two are combined and attached to the roadbed. Then, the fixing cone is inserted into the installation hole, so that the fixing cone and the triangular blocks on both sides are inserted into the soil. By rotating the knob, the lead screw and the cone block are moved down, pushing the moving plate to move to both sides, squeezing the spring outside the fixing rod, so that the extension block moves out from the inside of the fixing cone and is inserted into the soil laterally, realizing multi-point anchoring. The design of the triangular block and the extension block expands the anchoring area. Compared with the traditional single-point anchor, it can better disperse stress, enhance structural stability and pull-out resistance, thereby improving the overall effect of roadbed reinforcement.
[0018] 2. In this utility model, when assembling the first reinforcing plate and the second reinforcing plate, first pull out the two pins on the outside of the second reinforcing plate, align the protrusion of the first reinforcing plate with the insertion hole of the second reinforcing plate, and then insert it. Then insert the pins into the positioning holes of the protrusion to complete the assembly. When disassembling, simply pull out the pins and separate the two reinforcing plates. This realizes the convenient assembly and separation of the reinforcing plates, supports modular construction, allows for flexible adjustment, simplifies operation, and improves the efficiency of roadbed reinforcement construction.

[0026] 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.
[0027] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a highway subgrade protection and reinforcement structure, including a reinforcement plate 1, a reinforcement plate 2 on the outer right side of the reinforcement plate 1, and a disassembly and assembly component inside both the reinforcement plate 1 and the reinforcement plate 2. The disassembly and assembly component facilitates the combination and separation of the reinforcement plate 1 and the reinforcement plate 2. The reinforcement plate 1 and the reinforcement plate 2 are both equipped with a fixing component inside, which facilitates the fixing of the reinforcement plate 1 and the reinforcement plate 2. The reinforcement plate 1 and the reinforcement plate 2 are provided with diamond grids 3 around their interior. The grid design of the diamond grids 3 can disperse the subgrade load, make the stress uniform, avoid local damage caused by single-point stress, and improve the strength and durability of the reinforcement plate. The reinforcement plate 1 and the reinforcement plate 2 are provided with drainage channels 9 on both sides of their lower part. The drainage channels 9 can quickly guide rainwater or seepage water in the subgrade to flow out, preventing water from accumulating on the subgrade surface or behind the reinforcement plate.
[0028] The fixing assembly includes a fixing cone 11, with triangular blocks 15 fixedly connected to both sides of the lower part of the fixing cone 11. The design of the triangular blocks 15 can increase the contact area between the fixing cone 11 and the soil, thereby significantly increasing the anchoring force. A limiting plate 12 is fixedly connected to the upper part of the fixing cone 11, which serves to limit the fixing cone 11. A screw rod 13 is threadedly connected inside the fixing cone 11. A knob 14 is fixedly connected to the top of the screw rod 13, and a conical block 16 is fixedly connected to the bottom of the screw rod 13. Fixing rods 18 are fixedly connected to both sides inside the fixing cone 11, and the two fixing rods 18 can slide on both sides of their outer surfaces. The device is connected to a movable plate 20. Springs 19 are fitted on both sides of the two fixed rods 18. Extension blocks 21 are fixedly connected to the outside of the two movable plates 20. The extension blocks 21 serve to fix the device laterally. Through holes 17 are opened on both sides of the fixed cone 11. The two extension blocks 21 are slidably connected inside the two through holes 17. The through holes 17 facilitate the movement of the extension blocks 21. Mounting holes 10 are opened inside the reinforcing plates 11 and 2. The two fixed cones 11 are slidably connected inside the two mounting holes 10. The mounting holes 10 facilitate the installation of the fixed cones 11.
[0029] Specifically, when reinforcing the roadbed, firstly, reinforcing plate 1 and reinforcing plate 2 are combined to form an integral structure. Then, reinforcing plate 1 and reinforcing plate 2 are fitted to the roadbed surface, ensuring tight contact and evenly distributing the roadbed load. Next, the fixing cone 11 is inserted into the mounting hole 10 on the reinforcing plate, making it fit against the roadbed. The triangular block 15 connected to the lower part of the fixing cone 11 is then inserted into the soil, providing initial anchoring. Subsequently, by rotating the knob 14, the lower fixed screw rod 13 moves downward inside the fixing cone 11, simultaneously moving the conical block 16 fixed to the bottom of the screw rod 13. When the conical block 16 contacts the two moving plates 20, it exerts a compressive force on the moving plates 20, causing them to move to the sides. As the moving plates 20 move, the springs 19 installed on both sides of the fixed rod 18 are compressed, and the springs... When the spring 19 is subjected to force, it deforms, thereby generating a certain elastic reaction force. At the same time, the movement of the moving plate 20 further drives the extension blocks 21 fixed on both sides of its exterior to move outward synchronously, so that the extension blocks 21 move out from the interior of the fixed cone 11 and insert laterally into the interior of the soil. Through the above process, the fixed cone 11 completes the multi-point anchoring process. It not only relies on the lower triangular block 15 to insert into the soil to provide vertical fixing force, but also significantly expands the anchoring range and contact area through the lateral insertion of the extension blocks 21. The combined design of the triangular block 15 and the extension blocks 21 makes the fixed cone 11 form multi-directional anchoring force in the soil, further improving the pull-out resistance and anti-slip resistance of the fixed cone 11. Compared with the traditional single-point anchor fixing method, this multi-point distributed anchoring method more effectively disperses the stress on the roadbed, making the fixing of the reinforcement plate on the roadbed more stable, thereby improving the stability, durability and bearing capacity of the entire roadbed reinforcement structure.
[0030] Reference Figure 2 and Figure 4 The assembly includes two protrusions 4, which are fixedly connected to the right side of the first reinforcing plate 1. The two protrusions 4 are located inside the second reinforcing plate 2. Pins 6 are inserted into both sides of the inside of the second reinforcing plate 2. Through holes 7 are opened on both sides of the inside of the second reinforcing plate 2. The two pins 6 are slidably connected inside the two through holes 7. The through holes 7 facilitate the movement of the pins 6. Insertion holes 5 are opened on both sides of the outside of the second reinforcing plate 2. The two protrusions 4 are inserted into the two insertion holes 5, which provides initial fixation for the first reinforcing plate 1 and the second reinforcing plate 2. Positioning holes 8 are opened inside the two protrusions 4. The two pins 6 are threadedly connected to the two positioning holes 8, which improves the stability of the connection between the first reinforcing plate 1 and the second reinforcing plate 2.
[0031] Specifically, when combining reinforcement plate 1 and reinforcement plate 2, firstly, remove the two pins 6 that are inserted on the outside of reinforcement plate 2. Then, align the two protrusions 4 fixed on the outside of reinforcement plate 1 with the two insertion holes 5 on the outside of reinforcement plate 2. At this time, it is necessary to ensure that the direction and position of the insertion holes 5 and the protrusions 4 are completely aligned so that the protrusions 4 can be smoothly inserted into the insertion holes 5. Next, insert the two protrusions 4 of reinforcement plate 1 into the two insertion holes 5 of reinforcement plate 2 respectively, so that the two reinforcement plates are initially connected. After the insertion is completed, insert the two pins 6 into the positioning holes 8 pre-drilled inside the protrusions 4 to further fix reinforcement plate 1. The combination of reinforcement plate 1 and reinforcement plate 2 ensures that the combined reinforcement plate structure is stable and robust, capable of withstanding external forces and roadbed loads during construction. This design allows for quick and safe assembly of reinforcement plate 1 and reinforcement plate 2. When disassembly is required, simply pull out the two pins 6 to release the fixing between the protrusion 4 and the insertion hole 5. Subsequently, through a simple separation operation, reinforcement plate 1 can be removed from reinforcement plate 2, thus achieving module disassembly. This assembly and disassembly method is convenient to operate and can be completed quickly by hand, avoiding complex installation steps, reducing construction technical requirements, and thereby improving the efficiency of roadbed reinforcement construction.
[0032] Working principle: When reinforcing the roadbed, firstly, reinforcing plate 1 and reinforcing plate 2 are combined together. Then, reinforcing plate 1 and reinforcing plate 2 are attached to the roadbed. Next, the fixing cone 11 is inserted into the installation hole 10, so that the fixing cone 11 and the triangular blocks 15 fixed on both sides are inserted into the soil. Then, by rotating the knob 14, the knob 14 rotates, causing the lower fixed screw 13 to move downward inside the fixing cone 11. When the screw 13 moves, it moves the bottom fixed cone block 16 synchronously. When the cone block 16 contacts the two moving plates 20, it will squeeze the two moving plates 20, causing the two moving plates 20 to move to both sides. At the same time, the two... When the movable plate 20 moves to both sides, it compresses the springs 19 fixed on both sides of the two fixed rods 18, causing the springs 19 to deform under force. Then, when the two movable plates 20 move, they move synchronously with the extension blocks 21 fixed on both sides of the outside, so that the two extension blocks 21 can be moved out from the inside of the fixed cone 11 and inserted laterally into the soil. This makes it easy to fix the first reinforcement plate 1 and the second reinforcement plate 2. By inserting the triangular block 15 and the extension block 21 laterally into the soil, the anchoring area is expanded. Compared with the traditional single-point anchor fixing method, it can better disperse stress, enhance the stability and pull-out resistance of the structure, and thus improve the overall effect of roadbed reinforcement.
[0033] When it is necessary to combine reinforcement plate 1 and reinforcement plate 2, firstly, pull out the two pins 6 inserted on the outside of reinforcement plate 2. Then, align the two protrusions 4 fixed on the outside of reinforcement plate 1 with the two insertion holes 5 opened on the outside of reinforcement plate 2. Next, insert the two protrusions 4 into the two insertion holes 5. Then, insert the two pins 6 into the positioning holes 8 opened inside the protrusions 4 in sequence. This completes the combination of reinforcement plate 1 and reinforcement plate 2. When disassembling, pull out the pins 6, and then separate reinforcement plate 1 and reinforcement plate 2. This makes it easy to combine and separate reinforcement plate 1 and reinforcement plate 2. The convenience of combination and separation allows the reinforcement structure to be constructed in a modular manner. It can be flexibly adjusted according to site requirements, reducing unnecessary complicated operations and thus improving the efficiency of roadbed reinforcement construction.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
