[0002] Bridge pile foundations, as a crucial foundational structure in bridge engineering, directly impact the safety and service life of the bridge. However, in practical applications, bridge pile foundations often face various challenges, such as complex geological conditions and large load variations, leading to pile damage or insufficient bearing capacity. To address this issue, pile foundation reinforcement devices are typically used to enhance the bearing capacity and stability of the pile foundations.

[0003] However, existing bridge pile foundation reinforcement devices have the following technical problems: 1. Inapplicability to piles of different sizes: Existing reinforcement devices are often designed only for piles of specific sizes, lacking versatility and flexibility. When encountering piles of different diameters or lengths, different sizes of reinforcement devices need to be customized, increasing costs and time. 2. Complex installation: The installation of existing reinforcement devices usually requires complex construction steps and professional construction teams, which is not only time-consuming and labor-intensive but may also lead to unstable installation quality. 3. Poor reinforcement performance: Existing reinforcement devices have certain limitations in reinforcement effect and may not be able to fully meet the needs of pile foundation reinforcement.

[0041] Two first sliding blocks 6, one first sliding block 6 is arranged corresponding to each protective sheet 3, each first sliding block 6 is located below the corresponding push block 51, and the first sliding block 6 is connected with the outer side of the protective sheet 3 along the axial direction of the protective sheet 3; a push plate 8 is arranged on each first sliding block 6, which is an inclined plate extending outward from bottom to top, each push plate 8 is adapted to abut against the corresponding push block 51, so that the upward movement of the push plate 8 can push the corresponding push block 51 inward along the radial direction;

[0042] Two support rods 7, one support rod 7 is arranged corresponding to each protective sheet 3, one end of each support rod 7 is connected (hinged) with the corresponding first sliding block 6, and the other end extends downward along the radial direction outward and is connected (hinged) with the bottom plate 2; each support rod 7 is a hydraulic telescopic rod.

[0043] In the above technical solution, the present application provides a bridge reinforcing device for reinforcing and protecting a bridge pile foundation, which comprises a bottom plate 2 surrounding the bottom of the bridge pile foundation 1 for providing a stable supporting foundation; two protective sheets 3, each having a half-cylindrical structure with open ends, which form a protective sleeve of the cylindrical structure surrounding the circumferential side of the bridge pile foundation 1, and are connected in a detachable manner for easy installation and removal; two reinforcing sheets 4, each of which is coaxially arranged inside each protective sheet 3 in an arc-shaped structure, and the inner side of each reinforcing sheet 4 is tightly attached to the circumferential side of the bridge pile foundation 1 to increase the structural strength and stability of the pile foundation 1; two sliding rods 5, each of which is arranged corresponding to each reinforcing sheet 4, one end of each sliding rod 5 is connected to the outer side of the corresponding reinforcing sheet 4, and the other end is slid outward along the radial direction of the protective sheet 3, passes through the corresponding protective sheet 3 and extends to the outer side thereof.

[0044] Through the above specific embodiments, the bridge reinforcing device provided by the present application can be applied to bridge pile foundations 1 of different diameters, and has the advantages of easy installation, stable reinforcement, high strength, etc.

[0045] In another technical solution, the bridge reinforcing device, wherein one protective sheet 301 is provided with strip-shaped insertion blocks 31 on two rectangular sides along the axial direction, and a necked portion 32 is arranged in the middle; the other protective sheet 302 is provided with insertion grooves 33 which are recessed from the top to the bottom of two rectangular sides, and the insertion grooves 33 are arranged to pass through the necked portion 32 from the outside along the radial direction.

[0046] The insertion blocks 31 are arranged along the axial direction of the protective sheet 3 to the upper and lower ends of the corresponding protective sheet 3, and the length of the insertion grooves 33 along the axial direction is adapted to the insertion blocks 31. The insertion grooves 33 pass through the top of the corresponding protective sheet 3 along the axial direction, and the other side is sealed. The cross section of the insertion blocks 31 and the insertion grooves 33 along the radial direction is a reverse convex structure.

[0047] A plurality of elastic columns 34 which slide along the radial direction are arranged on the insertion blocks 31 in intervals, and the inner wall of the insertion grooves 33 is provided with accommodation grooves 35 which accommodate the elastic columns 34.

[0048] In the above technical solution, the bridge reinforcing device adopts a more delicate and ingenious design when connecting two protective sheets. Specifically:

[0049] One of the protective sheets 301, also referred to as the first protective sheet, is provided with strip-shaped insertion blocks 31 on two rectangular sides along the axial direction. The insertion blocks 31 not only extend along the axial direction, but also are provided with a necked portion 32 in the middle. The design of the necked portion 32 ensures that the insertion blocks 31 will not fall off along the radial direction after being inserted into the insertion grooves of the other protective sheet, and plays a certain guiding and positioning role. The other protective sheet 302, also referred to as the second protective sheet, is provided with insertion grooves 33 which are recessed from the top to the bottom of two rectangular sides. The insertion grooves 33 are arranged to pass through the necked portion 32 from the outside along the radial direction, so that the necked portion 32 of the first protective sheet can pass through smoothly. The length of the insertion grooves 33 along the axial direction is adapted to the insertion blocks 31, ensuring that the two can be closely matched. At the same time, the insertion grooves 33 pass through the top of the corresponding protective sheet along the axial direction (when the two protective sheets 3 are connected, one of the protective sheets slides along the axial direction from the top of the other protective sheet 302, and at the same time, the insertion blocks 31 are inserted into the insertion grooves 33 from the top of the insertion grooves 33), and the other side is sealed (after being inserted in place, the bottom of the insertion blocks 31 abuts against the inner wall of the other side of the insertion grooves). Such a design not only ensures the firmness of the insertion, but also simplifies the installation method.

[0050] It is worth noting that the cross section of the insertion blocks 31 and the insertion grooves 33 along the radial direction is a reverse convex structure. This design is to ensure that the two protective sheets will not separate along the radial direction after being connected by the insertion blocks 31 and the insertion grooves 33.

[0051] In order to further improve the stability of the connection between the two protective sheets, a plurality of radially sliding elastic columns 34 are arranged at intervals on the plug block 31. These elastic columns 34 can be deformed by being pressed by the inner wall of the plug slot 33 during the plugging process. When the plug block 31 is completely inserted into the plug slot 33, the elastic columns 34 can restore their original shape and be clamped into the accommodating grooves 35 provided on the inner wall of the plug slot 33. In this way, the two protective sheets 3 are fixed relative to each other in the axial direction, forming a more secure connection.

[0052] Through this refined detachable connection method, the two protective sheets 3 can move relative to each other in the axial direction and be connected by plugging. This connection can be achieved without the need for nuts or other connecting parts. This not only greatly simplifies the installation method and improves work efficiency, but also makes the overall structure of the bridge reinforcing device more compact and aesthetically pleasing. At the same time, the arrangement of elastic columns and accommodating grooves further improves the stability of the connection between the two protective sheets, enabling the bridge reinforcing device to maintain good performance and safety during long-term use.

[0053] In another technical solution, the bridge reinforcing device is provided with a through hole 311 extending through the protective sheet 3 in the axial direction in the middle of each plug block 31. A plug 36 is arranged in each through hole 311. A plurality of elastic columns 34 are arranged at intervals on the inner wall of the through hole 311, with one end of each elastic column 34 located in the through hole 311 and the other end extending radially to slide through the plug block 31 and be inserted into the corresponding accommodating groove 35.

[0054] In the above technical solution, each protective sheet still follows the previous design principles. Two rectangular sides of one protective sheet 301 are provided with strip-shaped plug blocks 31 extending in the axial direction. A through hole 311 extending in the axial direction of the protective sheet 3 is provided in the middle of the protective sheet 3 and penetrates the top of the protective sheet in the axial direction. This design not only facilitates the insertion of the plug, but also provides space for the arrangement of the elastic columns.

[0055] A plug 36 is cleverly arranged in the through hole 311, which can move freely in the axial direction of the through hole 311. The plug 36 can press the plurality of elastic columns 34 on the inner wall of the through hole 311 when it is completely pushed into the through hole 311.

[0056] The elastic column 34 is arranged on the inner wall of the through hole 311, the side wall of each elastic column 34 is radially slidingly connected with the inner wall of the through hole 311 and is provided with an elastic element (such as a reset spring, which resets when the plug is pulled up), and the other end is designed to extend radially and slide through the thin wall of the plug-in block 31; when the plug 36 is not inserted into the through hole 311, the other end of the elastic column does not protrude from the plug-in block 31 (reducing the frictional resistance in the process of inserting the plug-in block 31 into the plug-in slot 33), when the plug 36 is pushed in, the other end of the elastic column 34 is pushed radially outward, the reset spring is compressed, and until the other end of the elastic column 34 can be inserted into the accommodation groove 35 on the inner wall of the plug-in slot 33 of the other protective sheet 302; realizing the relative positioning of the two protective sheets in the axial direction

[0057] In actual operation, the installer only needs to align the plug-in block 31 of the first protective sheet with the plug-in slot 33 of the second protective sheet, and push them in the axial direction until they are in close contact. Then, the plug 36 is completely pushed into the through hole 311, at which time the elastic column 34 is extruded and expands radially outward, and finally firmly clamped into the accommodation groove 35. This connection method is not only simple and fast, but also greatly improves the connection strength and stability between the two protective sheets 3.

[0058] In terms of technical effects, the design cleverly uses the elastic deformation and recovery ability of the elastic column 34 by inserting the plug 36, achieving efficient and stable connection between the two protective sheets. This connection method does not require additional fasteners or adhesives, greatly simplifying the installation process, reducing costs, and improving the overall performance and reliability of the bridge reinforcement device.

[0059] In another technical solution, the bridge reinforcement device, each plug 36 is vertically inserted into the corresponding through hole 311 and extends to the lower side of the protective sheet 3 through the bottom of the plug-in slot 33.

[0060] A plurality of positioning holes are arranged on the plug 36 in the vertical direction, and a positioning hook 37 is arranged on each plug 36, which is arranged on the bottom plate 2 through a chain 371, and each positioning hook 37 can pass through one of the positioning holes.

[0061] In the above technical solution, the plurality of positioning holes are arranged on the bolt 36 in the vertical direction, and the positioning holes are used in cooperation with the positioning hooks 37 to realize the positioning of the bolt 36. The positioning hooks 37 are connected to the bottom plate 2 through the chain 371, and one positioning hook 37 is arranged corresponding to each bolt 36. The positioning hook 37 can pass through one of the positioning holes, so as to firmly lock the bolt 36 in the predetermined position. Through the locking of the bolt 36 by the positioning hook 37, not only the positioning of the bolt 36 is realized, but also the downward pulling force is applied to the entire protective sleeve structure. At the same time, in cooperation with the upward pushing of the supporting rod 7, the two jointly act, and the stability of the entire device reinforcing protection is significantly improved. Through the combination of the positioning hook 37 and the bolt 36, the effective positioning of the bolt is realized, and at the same time, the additional pulling force is applied to the entire protective sleeve structure, and the stability of the bridge reinforcing device is significantly improved.

[0062] In another technical solution, the bridge reinforcing device is characterized in that the bottom plate 2 is symmetrically provided with two sliding grooves 22, one sliding groove 22 is arranged below each supporting rod 7, and each sliding groove 22 extends along the radial direction of the protective sheet 3. A second sliding block 23 is slidably arranged in the sliding groove 22, and the other end of the supporting rod 7 is connected with the second sliding block 23.

[0063] A plurality of positioning grooves 24 are arranged in the length direction of the bottom of each sliding groove 22, and the second sliding block 23 is provided with a through hole in the vertical direction, and the through hole is connected with one of the positioning grooves 24 through a positioning column 25.

[0064] In the above technical solution, the sliding grooves 22 are symmetrically arranged on the bottom plate 2, and one sliding groove is arranged below each supporting rod 7 to ensure that the supporting rod can smoothly move in a specific direction (i.e. the radial direction of the protective sheet 3). The cross-sectional shape of the sliding groove is designed to match the second sliding block 23, so that the second sliding block 23 can freely slide in the sliding groove without shaking. The material of the sliding groove 22 needs to have sufficient strength and wear resistance to withstand the weight of the supporting rod 7 and the friction force in the moving process. High-quality steel or alloy materials can be used. The positioning grooves 24 are arranged in the length direction of the bottom of the sliding groove 22, and each positioning groove 24 is matched with the positioning column 25, so that the positioning column can be smoothly inserted and locked with the second sliding block 23. The shape and size of the positioning groove need to be accurately calculated to ensure that the positioning column can be tightly matched after being inserted to prevent loosening or falling off. The main function of the positioning groove is to provide a plurality of optional locking positions, which is convenient for the construction personnel to adjust the height and angle of the supporting rod according to the actual needs. When the second sliding block 23 moves to the required position, the corresponding positioning groove 24 is inserted through the positioning column 25, and the locking of the supporting rod 7 is realized.

[0065] In another technical solution, the bridge reinforcing device is characterized in that the bottom plate 2 is provided with a plurality of mounting holes, and each mounting hole is provided with an anchor rod 21 inserted therein, and the bottom of each anchor rod 21 is inserted into the soil layer under the ground through the mounting hole.

[0066] In another technical solution, the bridge reinforcing device is characterized in that the inner side of each reinforcing sheet 4 is provided with a plurality of anti-skid rubber protrusions.
