Description

Technical Field

[0001] This utility model relates to the technical field of protective structures, specifically a roadbed slope protection structure. Background Technology

[0002] Roadbed slope protection structures refer to a series of protective facilities installed on road slopes, cut slopes, fill slopes, bridge piers, etc., to protect slopes from erosion and damage caused by natural factors (such as rainwater and weathering) and human factors (such as vehicle traffic), ensuring the safety of roads and the surrounding environment. Common roadbed slope protection structures include retaining walls, retaining trenches, rock mesh, slope protection bricks, slope protection steel mesh, slope protection gabions, and slope protection concrete panels. These structures can effectively improve the stability and durability of roadbed slopes, reduce the risk of geological disasters, and ensure driving safety.

[0003] Utility model patent CN222614257U discloses a highly stable roadbed slope protection structure, belonging to the technical field of protection structures. It addresses the problem that existing slope protection methods typically use materials such as wire mesh wrapped around the slope, which, due to prolonged compression and rain erosion, suffer from low stability. The structure includes a first connecting plate; a first upright plate positioned on top of the first connecting plate; and a first stabilizing plate positioned on the top right side of the first connecting plate, with its right end fixedly connected to... Several buffer rods are present, all of which penetrate the second stabilizing plate and are movably connected to it. The left end of the second connecting plate is fixedly connected to the lower end of the second stabilizing plate. The second upright plate is located at the top center of the second connecting plate. A slope net is located on the top of the second connecting plate and also on the right end of the second stabilizing plate. Three ventilation openings are evenly spaced on the top of the slope net. Several planting areas are evenly spaced on the slope of the slope net. A drainage system is located at the top right end of the second connecting plate, and several sets of filter holes are provided on the left side of the inner wall of the drainage system. This scheme improves the stability of the roadbed and slope through T-shaped stabilizing components and filter components.

[0025] 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.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A roadbed slope protection structure includes: a base plate 1; a fixing plate 2 is fixedly connected to the top of the base plate 1, a slope protection plate 3 is provided on one side of the fixing plate 2, the slope protection plate 3 is fixedly connected to the fixing plate 2 and the base plate 1, a grid plate 4 is provided on the side of the fixing plate 2 away from the slope protection plate 3, the grid plate 4 is fixedly connected to the base plate 1 and the fixing plate 2, a buffer plate 5 is provided on the side of the fixing plate 2 near the grid plate 4, and four pin blocks 6 are provided at the bottom of the base plate 1 near the grid plate 4; an elastic mechanism 7 is provided between the buffer plate 5 and the fixing plate 2 to relieve and buffer the pressure on the roadbed; an expansion mechanism 8 is provided on the top of the pin blocks 6 to improve the stability of the connection between the device and the slope. The user inserts the pin blocks 6 into the holes inside the ground, and then installs and fixes the device through the expansion mechanism 8. When the foundation is fixed on the grid plate 4, the elastic mechanism 7 buffers the pressure on the foundation while the foundation is under pressure, so that the pressure on the foundation is released.

[0028] like Figure 2 and Figure 3 As shown, the elastic mechanism 7 includes: two slide rods 9 disposed between the buffer plate 5 and the fixed plate 2, with both ends of the slide rods 9 fixedly connected to side plates 10, and the side plates 10 being fixedly connected to the fixed plate 2; buffer blocks 11 are slidably connected to the outer surfaces of both ends of the slide rods 9, and two first fixed blocks 12 are fixedly connected to one side of each buffer block 11, with the two first fixed blocks 12 being fixedly connected to each other via a first rotating shaft 13; a buffer rod 14 is rotatably connected to the outer surface of the middle part of the first rotating shaft 13, and a second rotating shaft 15 is rotatably connected to the end of the buffer rod 14 away from the first rotating shaft 13; second fixed blocks 16 are fixedly connected to both ends of the second rotating shaft 15, and the second fixed blocks 16 are fixedly connected to the buffer plate 5. A first spring 17 is provided between the buffer block 11 and the side plate 10. The first spring 17 is respectively sleeved on the outer surface of both ends of the slide rod 9. When the foundation is subjected to pressure, the foundation squeezes the buffer plate 5. The buffer plate 5 moves towards the fixed plate 2 and drives the second fixed block 16. The second fixed block 16 drives the second rotating shaft 15. The second rotating shaft 15 squeezes one end of the buffer rod 14, so that the other end of the buffer rod 14 pushes the first fixed block 12 through the first rotating shaft 13. The first fixed block 12 drives the buffer block 11. The buffer block 11 slides on the surface of the slide rod 9 and squeezes the first spring 17 with the cooperation of the side plate 10. The first spring 17 buffers the pressure on the foundation with its own elasticity, so that the pressure is released.

[0029] like Figure 4 and Figure 5As shown, limit rods 18 are fixedly connected to both sides of the buffer plate 5. The end of the limit rod 18 away from the buffer plate 5 passes through the fixed plate 2 and the slope protection plate 3 and extends to the limit plate 19. The limit rod 18 is slidably connected to the fixed plate 2 and the slope protection plate 3. The end of the limit rod 18 located inside the slope protection plate 3 is fixedly connected to the limit block 19. The outer surface of the limit rod 18 located between the fixed plate 2 and the buffer plate 5 is fitted with a second spring 20. The second spring 20 cooperates with the first spring 17. When the buffer plate 5 moves towards the fixed plate 2, it also drives the limit rod 18. While the limit rod 18 slides inside the fixed plate 2 and the slope protection plate 3, the buffer plate 5 is squeezed by the cooperation of the fixed plate 2. The second spring 20 buffers the pressure on the buffer plate 5 through its own elasticity. The second spring 20 and the first spring 17 buffer the buffer plate 5 at the same time, which improves the buffering effect of the device and thus improves the protection effect of the device on the slope.

[0030] like Figure 5 As shown, damping sleeves 21 are fitted on the outer surface of the limiting rod 18 near the fixing plate 2 and the slope protection plate 3. The damping sleeves 21 are fixedly connected to the fixing plate 2 and the slope protection plate 3, which can buffer the rebound force generated by the second spring 20 after the first spring 17.

[0031] like Figure 6 As shown, the expansion mechanism 8 includes: a screw 22 fixedly connected to the top center of each pin block 6; the top of the screw 22 penetrates the base plate 1 and the grid plate 4 and extends to the knob 23; the knob 23 is fixedly connected to the screw 22; the screw 22 is rotatably connected to the base plate 1 and the grid plate 4; a lifting block 24 is threadedly connected to the bottom outer surface of each screw 22; an expansion plate 25 is fixedly connected to the top four corners of each lifting block 24; the top of each expansion plate 25 is fixedly connected to a fixing sleeve 30; the fixing sleeve 30 is fixedly connected to the base plate 1; the expansion plate 25 is fixedly connected to the lifting block 24 and the fixing sleeve 30. Each connection of the sleeve 30 is provided with a first bending groove 26, and each inner wall center of the expansion plate 25 is provided with a second bending groove 27. The user inserts the pin block 6 into the ground and then rotates the knob 23. As the knob 23 rotates, it drives the lifting block 24 to move upward. As the lifting block 24 moves, the distance between it and the fixed sleeve 30 decreases, thereby squeezing the two ends of the expansion plate 25. Through the cooperation of the first bending groove 26 and the second bending groove 27, the expansion plate 25 bends outward with the second bending groove 27, thereby installing the device on the ground.

[0032] like Figure 6 As shown, a limit ring 28 is provided between the lifting block 24 and the fixed sleeve 30. The limit ring 28 is fixed to the outer surface of the screw 22 and can limit the movement stroke of the lifting block 24.

[0033] like Figure 5As shown, rubber sleeves 29 are provided between the limiting plate 19 and the slope protection plate 3. The rubber sleeves 29 are respectively fitted on the outer surface of the limiting rod 18 to prevent the limiting plate 19 from impacting the slope protection plate 3 and generating a large noise when the limiting rod 18 drives the limiting plate 19 to rebound.

[0034] Working principle: The user inserts the pin block 6 into the hole inside the ground, and then rotates the knob 23. As the knob 23 rotates, it drives the lifting block 24 to move upward. As the lifting block 24 moves, the gap between it and the fixing sleeve 30 decreases, thus squeezing both ends of the expansion plate 25. The expansion plate 25 bends outward through the cooperation of the first bending groove 26 and the second bending groove 27, thereby installing the device on the ground and improving the stability of the connection between the device and the ground. This solves the problem that existing roadbed slope protection structures use fixed piles inserted vertically into the ground to fix the device, but due to the high smoothness of the fixed pile surface, the stability of the connection between the fixed pile and the ground is poor. Then, the foundation is fixed on the grid plate 4. When the foundation is under pressure, the foundation squeezes the buffer plate 5. The buffer plate 5 moves towards the fixing plate 2, while driving the second fixing block 16. The second fixing block 16 drives the second rotating shaft 15, which squeezes one end of the buffer rod 14, thus making the buffer... The other end of the punch rod 14 pushes the first fixed block 12 through the first rotating shaft 13. The first fixed block 12 drives the buffer block 11. While the buffer block 11 slides on the surface of the sliding rod 9, it squeezes the first spring 17 through the cooperation of the side plate 10. The first spring 17 buffers the pressure on the foundation through its own elasticity, so that the pressure is released. While the buffer plate 5 moves towards the fixed plate 2, it also drives the limiting rod 18. While the limiting rod 18 slides inside the fixed plate 2 and the slope protection plate 3, the buffer plate 5 squeezes the second spring 20 through the cooperation of the fixed plate 2. The second spring 20 buffers the pressure on the buffer plate 5 through its own elasticity. The second spring 20 and the first spring 17 buffer the buffer plate 5 at the same time, which improves the buffering effect of the device and thus better buffers the pressure on the slope, achieving the function of slope protection. This solves the problem that although the existing roadbed slope protection structure can buffer the pressure on the roadbed, its effect of buffering the pressure on the roadbed by only using a spring set in one direction is not good and its practicality is poor.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
