Description

Technical Field

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

[0002] The roadbed is the foundation of the track or road surface, and is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track and locomotive vehicles or road surface and traffic loads, while transmitting and diffusing the loads deep into the foundation. In civil engineering, the roadbed occupies an important position in terms of construction quantity, land area and investment. During the road construction process, in order to protect the edge of the roadbed and enhance its stability, a reinforcement structure is usually set on the side wall of the roadbed.

[0003] Existing reinforcement structures mostly use a support plate to abut the edge of the roadbed to reinforce the roadbed, in which the position of the support plate is relatively fixed and not easy to adjust. In actual use, affected by the construction environment and road design standards, the slope of the side of the roadbed may be different, which makes it possible for the support plate to not fit completely with the side of the roadbed, resulting in poor reinforcement effect of the structure on the roadbed. Therefore, we propose a road roadbed reinforcement structure to solve the above problems. Utility Model Content

The technical solution solves the problem that the existing reinforcement structure proposed in the above background technology mostly uses a support plate to abut the edge of the roadbed to reinforce the roadbed, wherein the position of the support plate is relatively fixed and not convenient to adjust. In actual use, affected by the construction environment and road design standards, the slope of the side of the roadbed may be different, which makes it possible for the support plate to fail to fully fit with the side of the roadbed, resulting in poor reinforcement effect of the structure on the roadbed.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figure 1 , Figure 2 and Figure 3 As shown, a roadbed reinforcement structure includes a base plate 1 and a support plate 2. A connecting groove 3 is opened through the left side of the base plate 1. Two connecting blocks 4 are fixedly connected to the lower end of the support plate 2. A rotating shaft 5 is fixedly connected between the two connecting blocks 4. The rotating shaft 5 is rotatably connected to the inside of the connecting groove 3.

[0025] A first slide groove 6 is provided at the upper end of the base plate 1, and a threaded rod 7 is rotatably connected inside the first slide groove 6. One end of the threaded rod 7 passes through the front end of the base plate 1 and is fixedly connected to an adjusting handle 8. A first slider 9 is threadedly connected to the outer surface of the threaded rod 7. Two first fixed blocks 10 are fixedly connected to the upper end of the first slider 9. A second slide groove 11 is provided at the front end of the support plate 2. A sliding rod 12 is fixedly connected inside the second slide groove 11. A second slider 13 is slidably connected to the outer surface of the sliding rod 12. Two second fixed blocks 14 are fixedly connected to the front end of the second slider 13. A first support rod 15 is rotatably connected between the two first sliders 9, and the other end of the first support rod 15 is rotatably connected between the two second fixed blocks 14.

[0026] Furthermore, by rotating the adjusting handle 8, the threaded rod 7 can be driven to rotate, thereby causing the first slider 9 on the surface of the threaded rod 7 to slide along the first slide groove 6. When the first slider 9 slides, it will pull the first support rod 15 to move, thereby causing the second slider 13 to slide along the second slide groove 11. As the first slider 9 and the second slider 13 slide, the support plate 2 will rotate, so that the position of the support plate 2 can be adjusted, so that the support plate 2 can be adjusted according to the slope of the side of the roadbed, so as to better fit the side of the roadbed.

[0027] Reference Figure 1 and Figure 4 As shown, a plurality of equally spaced fixing grooves 16 are provided on both sides of the upper end of the bottom plate 1 .

[0028] Furthermore, two third fixed blocks 17 are fixedly connected to the left and right sides of the front end of the support plate 2, and a sliding sleeve 18 is rotatably connected between the two third fixed blocks 17. A sliding cavity 19 is opened at the end of the sliding sleeve 18 away from the third fixed block 17, and a second support rod 20 is slidably connected to the inside of the sliding cavity 19. One end of the second support rod 20 abuts against the inside of the fixed groove 16. When the support plate 2 is adjusted to a suitable position, the second support rod 20 is abutted against the inside of the fixed groove 16 to support the support plate 2 and limit the position of the support plate 2 at the same time.

[0029] Furthermore, the front ends of the sliding sleeve 18 and the second support rod 20 are both provided with a plurality of evenly distributed fixing holes 21 , and the internal threads of the fixing holes 21 are connected with bolts 22 , and the position of the second support rod 20 can be fixed by the bolts 22 .

[0030] Reference Figure 1 and Figure 2 As shown, pile holes 23 are formed through the four corners of the upper end of the bottom plate 1 , and fixing piles 24 are arranged inside the pile holes 23 . The bottom plate 1 can be fixed on the ground through the pile holes 23 and the fixing piles 24 .

[0031] Reference Figure 3 As shown, a plurality of pins 25 are fixedly connected to the rear end of the support plate 2. The pins 25 can be inserted into the side of the roadbed, so that the connection between the support plate 2 and the side of the roadbed is more stable.

[0032] Working principle: When in use, the base plate 1 is fixed to the ground through the pile hole 23 and the fixed pile 24, and then the adjusting handle 8 is rotated to make the threaded rod 7 drive the first slider 9 to slide along the first slide groove 6. When the first slider 9 slides, the first support rod 15 will drive the second fixed block 14 to slide along the second slide groove 11, thereby causing the support plate 2 to rotate and fit against the side of the roadbed. Then, the sliding sleeve 18 is rotated and the second support rod 20 is pulled out along the sliding cavity 19 so that one end of it abuts against the fixed groove 16. Then, the bolt 22 is installed in the fixing hole 21 corresponding to the second support rod 20 and the sliding sleeve 18 to complete the installation.
