Description

Technical Field

[0001] This utility model relates to the field of railway bridge construction technology, specifically a railway bridge pile foundation reinforcement device. Background Technology

[0002] Railway bridge pile foundations are the core load-bearing structures buried underground in railway bridge engineering, which transfer the bridge load to deep stable soil and rock layers. Their core function is to ensure the stability and safety of the bridge under the dynamic load of trains through the friction between the pile body and the surrounding soil or the supporting force of the soil and rock layer at the pile tip. If there are problems with the railway bridge pile foundations, the stability and safety of the entire railway bridge will be reduced, and even serious safety accidents may occur.

[0003] In some railway bridge projects spanning rivers or lakes, the bridge pile foundations are submerged underwater for extended periods. Over time, the pile foundations are continuously eroded by flowing water, causing concrete to peel off and exposing the reinforcing steel bars, thus affecting the pile foundation's load-bearing capacity. Furthermore, floating debris such as tree trunks can easily be swept away by the current and impact the pile foundations, causing external damage and reducing the bridge structure's lifespan. Therefore, this invention provides a railway bridge pile foundation reinforcement device to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a railway bridge pile foundation reinforcement device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A railway bridge pile foundation reinforcement device includes a pile foundation body and a base plate. An arc-shaped plate is fixedly installed on the top surface of each of the two sets of base plates. A concrete layer is filled between the pile foundation body and the arc-shaped plate. A movable block is movably installed on the inner side of the arc-shaped plate. A clamping plate is fixedly installed on the surface of the movable block. An adjustment component for adjusting the position of the clamping plate is provided inside the arc-shaped plate. A protective plate is installed on the surface of the arc-shaped plate. An installation component for quickly assembling and disassembling the protective plate is provided inside the base plate. A buffer pad is fixedly installed on the surface of the protective plate.

[0006] As a further embodiment of this utility model, a connecting plate is fixedly installed on the surface of the arc-shaped plate, and bolts are threadedly connected to the inside of the connecting plate, with multiple sets of bolts provided.

[0007] As a further embodiment of this utility model, the adjusting assembly includes a bidirectional lead screw rotatably mounted inside the arc-shaped plate, a handwheel fixedly mounted at the top of the bidirectional lead screw, a threaded block threaded onto the surface of the bidirectional lead screw, a connecting rod hinged onto the surface of the threaded block, and the connecting rod rotatably connected to the moving block.

[0008] As a further embodiment of this utility model, the mounting assembly includes a spring groove formed inside the base plate, a movable rod slidably mounted inside the spring groove, a movable block fixedly mounted at one end of the movable rod, a first spring fixedly mounted on the surface of the movable block, the first spring being sleeved on the surface of the movable rod, and an insert rod fixedly mounted on the side of the movable block away from the first spring.

[0009] As a further embodiment of this utility model, an installation block is fixedly installed on the bottom surface of the protective plate, and an insertion hole is opened inside the installation block. The insertion hole is correspondingly arranged with the insertion rod. An installation groove is opened on the surface of the base plate, and the installation groove is correspondingly arranged with the installation block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. When this utility model is used, by adjusting the settings of the components, the clamping plates can move and fit tightly against the surface of the pile foundation. The two sets of clamping plates can move closer or further apart, which can surround and support pile foundations of different diameters. At the same time, it can provide interlocking force for fixing the concrete layer, forming a composite force system of "pile-support-concrete". This reduces the risk of peeling of the concrete layer due to aging or vibration and improves the reinforcement strength of the pile foundation.

[0013] 2. When this utility model is used, the buffer component is set so that when it is subjected to external impact force, it first acts on the buffer plate. Under the action of the second spring, the impact force transmitted to the pile foundation can be reduced, thereby improving the protection effect on the pile foundation. By setting the installation component, the protective plate can be quickly disassembled and installed by pulling the movable rod to drive the insertion rod into or out of the insertion hole, which facilitates the replacement of the protective plate and the buffer plate.

[0021] 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.

[0022] Please see Figures 1-6In this embodiment of the utility model, a railway bridge pile foundation reinforcement device includes a pile foundation body 1 and a base plate 2. An arc-shaped plate 3 is fixedly installed on the top surface of both sets of base plates 2. A concrete layer 16 is filled between the pile foundation body 1 and the arc-shaped plate 3. To facilitate the fixed installation of the two sets of arc-shaped plates 3 together, a connecting plate 4 is fixedly installed on the surface of the arc-shaped plate 3. Bolts 5 are threadedly connected to the inside of the connecting plate 4, and multiple sets of bolts 5 are provided. A movable block 11 is movably installed on the inner side of the arc-shaped plate 3. A clamping plate 12 is fixedly installed on the surface of the movable block 11. To facilitate the stable movement of the clamping plate 12 within the arc-shaped plate 3, a fixing plate 13 is fixedly installed on the inner side of the arc-shaped plate 3. A limit groove 14 is formed inside the fixing plate 13. The movable block 11 is fixedly installed on the surface of the fixed plate 11. A limiting block 15 is slidably installed in a limiting groove 14. An adjusting component for adjusting the position of the clamping plate 12 is provided inside the arc plate 3. A protective plate 17 is installed on the surface of the arc plate 3. In order to ensure that the protective plate 17 can be installed more stably on the arc plate 3, a T-shaped block 18 is fixedly installed on the side of the protective plate 17 near the arc plate 3. A T-shaped groove 19 is opened on the surface of the arc plate 3. The T-shaped block 18 is slidably installed inside the T-shaped groove 19. An installation component for quick disassembly and assembly of the protective plate 17 is provided inside the base plate 2. A buffer pad 28 is fixedly installed on the surface of the protective plate 17. A buffer plate 29 is fixedly installed on the surface of the buffer pad 28. A buffer component for providing buffering for the pile foundation body 1 is provided on the surface of the protective plate 17.

[0023] When reinforcing the pile foundation 1, the diameter of different pile foundations 1 may vary. In order to facilitate the reinforcement of pile foundations 1 with different diameters, it is necessary to adjust the position of two sets of clamping plates 12. The adjustment component includes a two-way screw 6 rotatably installed inside the arc plate 3. A handwheel 7 is fixedly installed at the top of the two-way screw 6. A threaded block 8 is installed on the surface of the two-way screw 6. In order to ensure that the threaded block 8 can move up and down stably within the arc plate 3, a sliding groove 9 is provided on the inner side of the arc plate 3. The threaded block 8 is slidably installed in the sliding groove 9. A connecting rod 10 is hinged to the surface of the threaded block 8. The connecting rod 10 is rotatably connected to the moving block 11.

[0024] During long-term use, the protective plate 17 and the buffer plate 29 will be subjected to continuous impacts and are prone to damage. In order to facilitate the replacement of the damaged protective plate 17 and the buffer plate 29, an installation component needs to be designed to facilitate quick assembly and disassembly. The installation component includes a spring groove 22 opened inside the base plate 2. A movable rod 23 is slidably installed inside the spring groove 22. A movable block 24 is fixedly installed at one end of the movable rod 23. A first spring 25 is fixedly installed on the surface of the movable block 24. The first spring 25 is sleeved on the surface of the movable rod 23. A plug rod 26 is fixedly installed on the side of the movable block 24 away from the first spring 25.

[0025] A mounting block 20 is fixedly installed on the bottom surface of the protective plate 17. The mounting block 20 has an insertion hole 21 inside, which is corresponding to the insertion rod 26. A mounting groove 27 is provided on the surface of the base plate 2, which is corresponding to the mounting block 20.

[0026] In order to reduce the impact force on the pile foundation body 1, a buffer assembly needs to be installed on the outside of the pile foundation body 1. The buffer assembly includes a fixed cylinder 30 fixedly installed on the surface of the protective plate 17. A second spring 31 is fixedly installed inside the fixed cylinder 30. A buffer rod 32 is fixedly installed at one end of the second spring 31. The buffer rod 32 is fixedly connected to the buffer plate 29.

[0027] Ground nails 33 are fixedly installed on the bottom surface of the base plate 2, and reinforcing ribs 34 are fixedly installed on the inner side of the arc plate 3. There are four sets of ground nails 33 and reinforcing ribs 34. By setting the ground nails 33, the ground nails 33 are inserted into the soil layer when installing the base plate 2, which can better fix the base plate 2. By setting the reinforcing ribs 34, the overall strength of the arc plate 3 can be improved, and the reinforcement effect on the pile foundation 1 can be enhanced.

[0028] The working principle of this utility model is as follows: Workers place two sets of base plates 2 on both sides of the pile foundation 1, with the ends of the two sets of base plates 2 in contact, allowing the ground nails 33 to insert into the soil. At this time, the two sets of connecting plates 4 are connected by rotating bolts 5, fixing the two arc-shaped plates 3 to the outside of the pile foundation 1. Rotating the handwheel 7 drives the bidirectional screw 6 to rotate, which in turn drives the threaded block 8 to move within the sliding groove 9, causing the connecting rod 10 to move, which in turn drives the moving block 11 to move. The limiting block 15 on the moving block 11 slides within the limiting groove 14, causing the clamping plate 12 to move and tightly fit against the surface of the pile foundation 1. The two sets of... The clamping plates 12 can move closer or further apart to enclose and support pile foundations 1 of different diameters, thereby reinforcing the pile foundations 1. After initial reinforcement of the pile foundations 1 by the clamping plates 12, concrete is poured into the gap between the pile foundations 1 and the arc-shaped plates 3. After solidification, a concrete layer 16 is formed, which can fill and reinforce cracks or minor defects on the surface of the pile foundations 1. At the same time, the supporting components between the two sets of arc-shaped plates 3, such as the connecting rods 10, the moving blocks 11, and the clamping plates 12, can provide interlocking force for the concrete, forming a composite force system of "pile-support-concrete", reducing the impact of aging or vibration on the concrete layer 16. To reduce the risk of peeling and increase the reinforcement strength of the pile foundation 1, the movable rod 23 is pulled outward, causing the movable block 24 to move, compressing the first spring 25. The insertion rod 26 is moved out of the mounting groove 27, inserting the mounting block 20 at the bottom of the protective plate 17 into the mounting groove 27. At the same time, the T-shaped block 18 is inserted into the T-shaped groove 19. The movable rod 23 is released, and under the restoring force of the first spring 25, the movable block 24 is pushed to move, causing the insertion rod 26 to move, so that the insertion rod 26 is inserted into the insertion hole 21, thus fixing the protective plate 17 in place. At the same time, when subjected to a collision, the colliding object first contacts the buffer plate 29, and the buffer plate 29 is then used to prevent the collision. A buffer assembly is provided on the back of the impact plate 29. When an external impact force is applied to the buffer plate 29, the second spring 31 is compressed, converting kinetic energy into elastic potential energy. During the recovery deformation process, the second spring 31 consumes some energy through internal friction and hysteresis effect, reducing the impact force transmitted to the pile foundation 1, thereby improving the protection effect on the pile foundation 1. When the protective plate 17 and the buffer plate 29 are damaged during long-term use, the movable rod 23 is pulled outward to move the movable block 24, so that the insertion rod 26 is moved out of the insertion hole 21, and the protective plate 17 can be moved upward to replace the protective plate 17 and the buffer plate 29.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
