Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a highway roadbed reinforcement structure. Background Art

[0002] Expressways are multi-lane roads designed for vehicles to travel in different directions and lanes, with fully controlled access. They have high speeds and many lanes. They are important transportation links connecting cities and regions, shortening driving time and promoting economic exchanges, personnel exchanges and material transportation. Roadbed reinforcement structures are required during construction because complex geological conditions are often encountered, such as low bearing capacity of soft soil foundations. Reinforcement structures can enhance their bearing capacity and prevent uneven settlement. At the same time, they can resist damage from natural factors, such as rain erosion of slopes and the impact of freeze-thaw cycles on roadbeds in cold areas, to ensure roadbed stability. They can also reduce roadbed and pavement diseases and extend the service life of expressways.

[0003] Highway roadbed reinforcement methods generally include pile foundation reinforcement structure, cement mixing pile, reinforced soil reinforcement structure, anchor reinforcement structure, and reinforced side wall, tie rod, geogrid layer and partition wall combination. Among them, anchor reinforcement structure and reinforced side wall are to apply a certain prestress at the end of the anchor rod so that the anchor rod generates precompression stress in the soil, thereby improving the shear strength and stability of the soil. Prestressed anchor rods can effectively control the deformation of the roadbed and reduce the settlement and displacement of the roadbed. It is suitable for sections with poor soil quality and complex terrain, such as roadbed reinforcement of mountain highways.

[0004] However, in anchor reinforcement structures, their own stress is usually used to protect the road surface, thereby achieving the effect of reinforcement to prevent roadbed deformation. However, long-term use will reduce the service life of the anchor, which will lead to stress deterioration, and further cause roadbed deformation. Therefore, a highway roadbed reinforcement structure is proposed to solve the above problem. Utility Model Content

[0037] Working principle: When it is necessary to use the reinforcement structure to repair the highway roadbed, first place multiple support plates 1 on one side of the roadbed. At this time, the reinforcement plate 3 is pressed against the side of the roadbed. At this time, the extension plate 19 of one support plate 1 is inserted into the installation groove 20 of another support plate 1, so that the card block 25 is inserted into the extension plate 19 for a stable engagement effect. At this time, the anchor rod 18 is inserted into the soil. At this time, when the reinforcement plate 3 receives the outward expansion stress of the roadbed, the support frame 6 is pushed to rotate by the reinforcement plate 3. Through the rotation of the support frame 6, the sliding block 5 is driven to slide within the outer wall of the fixed frame 4. At this time, the rack column 7 is driven by the sliding block 5 to mesh with the gear 10, and the gear 10 is rotated to drive the outer wall support leg 11 of the rotating shaft 9 to rotate. At this time, the support leg 11 is rotated to drive the support foot 12 to contact the ground for further stable support. At this time, the sliding block 5 is moved, and the sliding block 5 drives the inclined block 13 to slide, so that the inclined block 13 pushes the fixed block 16 to move the anchor rod 18 downward, and the fixed block 16 squeezes the spring 15 to contract, so as to drive the anchor rod 18 to insert into the soil for stability and prevent the reinforcement plate 3 from displacement.

[0038] Secondly, when the reinforcement structure needs to be disassembled, the sliding rod 21 is pressed to compress the spring three 26, thereby achieving the effect of driving the hinge seat 22 to move. At this time, the hinge seat 22 is moved to drive the connecting rod 23 to rotate. At this time, the connecting rod 23 is moved to push the sliding plate 24 to move the block 25. At this time, the block 25 is moved to detach from the extension plate 19, thereby achieving the effect of quick disassembly. At this time, the reinforcement plate 3 is pressed to make the support plate 1, the connecting plate 2 and the reinforcement plate 3 flush, thereby reducing the footprint and achieving the effect of facilitating transportation and handling.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
