Description

Technical Field

[0001] This application relates to the field of bridge pile foundation reinforcement technology, and in particular to a pile foundation reinforcement device for water-crossing bridges. Background Technology

[0002] The main reason for the need to reinforce the pile foundations of bridges spanning water is that water erosion, settlement, and other natural factors can affect the stability and bearing capacity of the pile foundations, especially in aquatic environments such as rivers and lakes. Reinforcement measures typically include increasing the bearing capacity, corrosion resistance, and seismic resistance of the pile foundations, thereby improving the safety and service life of the bridge. Reinforcement devices are usually closely related to the structural characteristics of the pile foundations, soil conditions, and water flow characteristics; for example, by adding pile caps, reinforcing the pile body, and using steel reinforcement.

[0003] A search revealed Chinese patent publication number CN218291931U, which discloses a reinforcement device for water-crossing bridge pile foundations. The device includes a first protective plate and a second protective plate, which are joined together to form a protective frame. A first connecting rod is rotatably connected to the upper surface of the first protective plate, and a second connecting rod is rotatably connected to the upper surface of the second protective plate. A first fixing half-ring is rotatably connected to the upper end of the first connecting rod, and a second fixing half-ring is rotatably connected to the upper end of the second connecting rod. The first and second fixing half-rings are joined together by a connecting component to encircle and fix the water-crossing bridge pile foundation. Concrete grout is poured into the protective frame formed by the first and second protective plates. This invention utilizes the protective frame formed by the first and second protective plates to resist the impact of prolonged water flow and to divert the water flow, thereby extending the service life of the water-crossing pile foundation.

[0004] The aforementioned patent specification mentions "a reinforcement device for the pile foundation of a bridge navigating water, comprising a first protective plate and a second protective plate, the first and second protective plates being joined together to form a protective frame, a first connecting rod being rotatably connected to the upper surface of the first protective plate, a second connecting rod being rotatably connected to the upper surface of the second protective plate, a first fixed half-ring being rotatably connected to the upper end of the first connecting rod, and a second fixed half-ring being rotatably connected to the upper end of the second connecting rod, the first and second fixed half-rings being joined together by a connecting component to encircle and fix the pile foundation of the bridge navigating water, and concrete grout being poured within the protective frame formed by the first and second protective plates." This structure resists water flow impact and diverts water through the protective frame, extending the service life of the pile foundation. However, it has the following drawbacks: Firstly, the combination of the first and second protective plates forms a pentagonal structure, which easily creates a direct impact when water flows back, resulting in insufficient diversion effect. Utility Model Content

[0005] The purpose of this application is to provide a reinforcement device for the pile foundation of a water-crossing bridge, which aims to improve the problem that the geometry of the protective structure used in some existing devices is not well matched with the hydrodynamic characteristics, making it difficult to effectively cope with complex water flow conditions and easily causing local stress concentration.

[0006] The present application provides a water-crossing bridge pile foundation reinforcement device with the following technical solution: a water-crossing bridge pile foundation reinforcement device, including a column base, a reinforcement structure fixedly connected to the outside of the column base, two quick-fixing mechanisms fixedly connected to the outside of the column base, a diversion block fixedly connected to the bottom of each of the two quick-fixing mechanisms, and multiple connecting bolts fixedly connected to the inside of each of the two diversion blocks.

[0007] The quick-fixing mechanism includes two positioning blocks. A connecting assembly is fixedly connected to the outside of each positioning block. Multiple compression screws are threadedly connected to the inside of each positioning block. A release block is fixedly connected to the outside of each compression screw. A return spring is fixedly connected to the side of the release block near the column base. The other end of the return spring is fixedly connected to the inside of the positioning block. A positioning shaft is rotatably connected to the side of the release block near the column base. A compression block is fixedly connected to the side of the positioning shaft near the column base. A friction layer is fixedly connected to the side of the compression block near the column base. A splicing fixing block is fixedly connected to the top of each positioning block. A splicing screw is slidably connected inside the splicing fixing block. The bottom of the splicing screw is threadedly connected to the inside of another positioning block.

[0008] The above technical solutions achieve the following: reinforced structure enhances pile foundation stability; quick fixing mechanism enables rapid installation and disassembly through components such as compression screws, and reset spring ensures connection reliability; diversion block, in conjunction with connecting bolts, disperses the impact force of water flow; friction layer increases friction with pile foundation, thereby improving the overall scour resistance and bearing capacity of pile foundation, and is convenient to install and maintain.

[0009] As a further description of the above technical solution: the reinforcement structure includes two reinforcement main beams, the adjacent sides of the two reinforcement main beams are fixedly connected to the outside of the column base, and multiple vertical reinforcement blocks are fixedly connected inside the two reinforcement main beams, and a transverse reinforcement block is fixedly connected to the adjacent sides of the multiple vertical reinforcement blocks.

[0010] The above-described solution involves fixing the reinforced structure to the column foundation via two main reinforcing beams, combined with multiple vertical and horizontal reinforcing blocks to form a three-dimensional grid-like support system. The vertical reinforcing blocks enhance the longitudinal bending stiffness of the pile foundation, while the horizontal reinforcing blocks optimize the horizontal load transfer path. The synergistic effect of both significantly improves the overall bending and shear resistance of the pile foundation, effectively disperses external loads, enhances the stability and bearing capacity of the pile foundation in water-related environments, and extends the structural service life.

[0011] As a further description of the above technical solution: the connecting assembly includes multiple connecting plates, and the multiple connecting plates are fixedly connected to the outside of the positioning block on the side adjacent to the column base. A connecting rod is rotatably connected to the side adjacent to two of the connecting plates, and a spherical limiting block is fixedly connected to the other end of the connecting rod. Two connecting bases are fixedly connected to the top of the two diversion blocks, and the outside of the spherical limiting block is rotatably connected to the inside of the connecting base.

[0012] The above solution involves fixing the positioning block to the column base via a connecting plate, and rotatably connecting the connecting rod to the spherical limiting block and embedding it into the connecting base, forming a rotatable flexible connection structure. This design allows the diversion block to adaptively adjust its angle according to the water flow direction, effectively dispersing the impact force of water flow from different directions. Simultaneously, the spherical hinge releases stress, avoiding localized damage caused by rigid connections, enhancing the overall flexibility and impact resistance of the device, and improving the stability of the pile foundation in complex water flow environments.

[0013] As a further description of the above technical solution: the positioning block has a sliding groove inside, the release block is externally slidably connected to the inside of the sliding groove, and the reset spring is externally fixedly connected to the inside of the sliding groove.

[0014] The above solution involves a sliding groove within the positioning block, allowing the release block to slide within it, while a return spring is fixed within the groove. This structure enables the release block to achieve a tight fit or separation between the compression block and the pile foundation through sliding. The return spring provides elastic cushioning, enhancing the connection tightness through the compression screws and releasing stress through elastic deformation upon impact, preventing hard damage. This ensures the stability and adjustability of the quick-fixing mechanism, improving installation efficiency and structural safety.

[0015] As a further description of the above technical solution: the interior of the reinforced main beam is provided with a through hole, and the external sliding connection of the splicing fixing block is inside the through hole.

[0016] The above solution involves creating through holes inside the main beam, allowing the splicing fixing blocks to slide within these holes. This design enables the splicing fixing blocks to be flexibly adjusted in position, adapting to the reinforcement needs of pile foundations of different sizes and enhancing the versatility of the device. The sliding connection method facilitates rapid on-site positioning and assembly, reducing construction errors. Simultaneously, the through holes provide a guide path for the splicing screws, ensuring connection accuracy and making the connection between the main beam and the column foundation more stable, thereby improving the assembly efficiency and stress uniformity of the overall structure.

[0017] As a further description of the above technical solution: one end of each of the two diverter blocks is provided with a snap-fit ​​groove, and the other end of each of the two diverter blocks is provided with a snap-fit ​​block. The snap-fit ​​block is slidably connected inside the snap-fit ​​groove, and the outside of the connecting bolt is slidably connected inside the snap-fit ​​block.

[0018] The above solution involves a sliding connection structure between the snap-fit ​​grooves at both ends of the diversion block and the snap-fit ​​block itself, secured by connecting bolts. This design allows for flexible adjustment of the diversion block's splicing length and angle to adapt to different pile foundation sizes and water flow directions. The snap-fit ​​sliding structure facilitates rapid on-site assembly, reducing the difficulty of underwater operations. While ensuring a secure splicing, the connecting bolts allow the diversion block to rotate slightly under water flow impact. This "sliding-limiting" mechanism disperses the impact force, avoids stress concentration, and enhances the device's adaptability and impact resistance to complex water flow environments.

[0019] As a further description of the above technical solution: both of the diversion blocks are U-shaped annular blocks, the two diversion blocks are combined into a hexagonal annular block, and the edges of both diversion blocks are rounded.

[0020] The above solution employs a U-shaped ring design for the two diversion blocks, which, when combined, form a hexagonal ring structure with rounded edges. This design evenly disperses the impact force of water flow from all directions, and the hexagonal structure guides water flow at different angles, reducing localized scouring. The U-shaped design increases the contact area with the pile foundation, enhancing stability. The rounded edges prevent the formation of sharp eddies, reducing water flow resistance and noise, while also minimizing potential harm to aquatic life, thus combining structural stability with eco-friendliness.

[0021] As a further description of the above technical solution: the top of the connecting base has a funnel-shaped groove with a larger upper part and a smaller lower part, the outside of the connecting rod is located inside the funnel-shaped groove, and the inside of the connecting base has a spherical groove, the top of the spherical groove is in contact with the bottom of the funnel-shaped groove.

[0022] The above solution involves a funnel-shaped groove at the top of the connecting base, wider at the top and narrower at the bottom. A spherical groove is formed inside the funnel-shaped groove and fits snugly against the bottom of the funnel-shaped groove, where the connecting rod is placed. This structure guides the connecting rod to quickly align with the spherical groove through the funnel-shaped groove, facilitating the embedding and installation of the spherical limiting block and improving assembly efficiency. The spherical groove allows the connecting rod to rotate 360°, enabling the diverter block to flexibly adjust its angle according to the water flow direction, dispersing multi-directional impact forces. The funnel-shaped design also concentrates water flow energy to the spherical hinge point, uniformly transmitting stress through the spherical structure, avoiding localized stress concentration, and enhancing the stability and water flow adaptability of the connecting components.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In this utility model, two positioning blocks are connected by the interlocking fixing block and the interlocking screw at the top of the positioning blocks. Then, the extrusion screw threaded inside the positioning block pushes it close to the column base, so that the friction layer on the wall of the extrusion block is in contact with the surface of the column base. The friction layer itself is made of abrasive material to increase the friction force, thereby preventing the reinforcement device from shifting during use and ultimately affecting the reinforcement effect. The positioning block is connected to two diversion blocks through the connecting component. The two diversion blocks are combined to form a hexagonal block, so that the two diversion blocks can divert the water flow in various directions to reduce the impact force generated by the water flow and thus improve the reinforcement effect.

[0025] 2. In this utility model, two reinforcing main beams fixed to the outside of the column base serve as main beams. These main beams are connected to multiple vertical reinforcing blocks. Multiple horizontal reinforcing blocks connected to the vertical reinforcing blocks form a ring, thereby enhancing the efficiency of stress transmission from the column base to the reinforcing main beams. Furthermore, the presence of the reinforcing main beams not only enhances the bending stiffness of the column base but also forms an effective stress transmission path between the two distribution blocks and the column base, transferring the vertical load more evenly to the surrounding soil and improving the overall bearing capacity of the column base.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0033] Example: A pile foundation reinforcement device for water-crossing bridges, referring to... Figure 1 , Figure 4 , Figure 5 The system includes a column base 1, which is the core structure of the reinforcement device. The column base 1 bears the weight of the bridge pile foundation and is in direct contact with the water flow. A reinforcement structure 5 is fixedly connected to the outside of the column base 1. The reinforcement structure 5 enhances the overall stability of the column base 1 and prevents the impact of water flow and settlement. Two quick-fixing mechanisms 3 are also fixedly connected to the outside of the column base 1. These mechanisms establish the initial connection between the column base 1 and the reinforcement device and reinforce it through friction, ensuring the stability of the device. A diversion block 4 is fixedly connected to the bottom of each of the two quick-fixing mechanisms 3. The diversion block 4 is a key component in the reinforcement device used to guide the water flow. Each diversion block 4 is a U-shaped ring block. Multiple diversion blocks 4 are combined to form a hexagonal ring structure. Multiple connecting bolts 6 are fixedly connected inside each of the two diversion blocks 4.

[0034] Specifically, when this bridge pile foundation reinforcement device is in operation, two quick-fixing mechanisms 3 are first installed at designated positions on the outside of the column foundation 1. These quick-fixing mechanisms 3 achieve initial positioning with the column foundation 1. Then, a diversion block 4 is installed at the bottom of the quick-fixing mechanism 3 and secured using connecting bolts 6 within the diversion block 4, ensuring a stable connection between the diversion block 4 and the column foundation 1. Simultaneously, a reinforcement structure 5 is pre- or synchronously fixed to the outside of the column foundation 1, providing structural reinforcement. Through the synergistic effect of the quick-fixing mechanism 3, the diversion block 4, and the reinforcement structure 5, the entire device reinforces the column foundation 1 and disperses and guides the impact of water flow, improving the stability of the pile foundation in a water-filled environment.

[0035] The quick-fixing mechanism 3 includes two positioning blocks 31. Positioning blocks 31 provide initial positioning and are fixed to the column base 1. A connecting assembly 2 is fixedly connected to the outside of each positioning block 31. Multiple compression screws 32 are threaded inside each positioning block 31. Release blocks 33 are fixedly connected to the outside of each compression screw 32. The compression screws 32 and release blocks 33 work together to control the fixing force. By rotating and adjusting the pressure of the compression block 35, the friction layer 36 is ensured to be in close contact with the surface of the column base 1, thereby achieving a firm fixing effect. A return spring 34 is fixedly connected to the side of the release block 33 near the column base 1. When disassembly is required, rotating the compression screws 32 releases the compression of the release block 33, and the return spring 34 causes the release block 33 to spring back, releasing the compression block 35 and quickly disengaging the fixing connection. The other end of the return spring 34 is fixedly connected to the inside of the positioning block 31. A positioning shaft 39 is fixedly connected to the side of the release block 33 near the column base 1. A pressing block 35 is fixedly connected to the side of the shaft 39 near the column base 1. The positioning shaft 39 is rotatably connected to the positioning block 31, which drives the pressing block 35 to move closer to the column base 1, ensuring that the pressing block 35 generates sufficient friction to stably fix the entire device. A friction layer 36 is fixedly connected to the side of the pressing block 35 near the column base 1. The connecting bolt 6 is used to connect the snap-fit ​​blocks of the two diversion blocks 4. During assembly, the bolt locking ensures the stability of the entire diversion system. A splicing fixing block 38 is fixedly connected to the top of the positioning block 31. The splicing fixing block 38 serves to connect the reinforcement structure 5 and the column base 1. It is located in the through hole inside the reinforcement main beam 51. A splicing screw 37 is slidably connected inside the splicing fixing block 38. The bottom of the splicing screw 37 is externally threaded to the inside of another positioning block 31. A sliding groove is opened inside the positioning block 31. The outside of the release block 33 is slidably connected to the inside of the sliding groove. The outside of the return spring 34 is fixedly connected to the inside of the sliding groove.

[0036] Specifically, during operation, the device first assembles two positioning blocks 31 onto the outside of the column base 1 using splicing screws 37 and splicing fixing blocks 38. Then, tightening the compression screws 32 causes the release block 33 to slide within the sliding groove of the positioning block 31, compressing the return spring 34. The release block 33, through the splicing screws 37, pushes the compression block 35 closer to the column base 1 until the friction layer 36 tightly adheres to the surface of the column base 1, achieving a tight connection between the quick-fixing mechanism 3 and the column base 1. For disassembly, tightening the compression screws 32 in the opposite direction causes the return spring 34 to spring back, resetting the release block 33 and compression block 35, releasing the pressure on the column base 1, thus completing the disassembly.

[0037] The connecting assembly 2 includes multiple connecting plates 24. The multiple connecting plates 24 are fixedly connected to the outside of the positioning block 31 on the side close to the column base 1. A connecting rod 23 is rotatably connected to the side close to two connecting plates 24. The connecting plates 24 fix the diverting block 4 to the outside of the column base 1 through rotational connection. The rotation of the connecting rod 23 ensures that the diverting block 4 can change its angle with the change of water flow. A spherical limiting block 22 is fixedly connected to the other end of the connecting rod 23. Two connecting bases 21 are fixedly connected to the top of the two diverting blocks 4. The connecting rod 23 cooperates with the spherical limiting block 22 to drive the diverting block 4 to adjust its angle according to the direction of water flow. The spherical groove design allows the diverter block 4 to adaptively adjust in the direction of water flow, ensuring that the water flow impact force is evenly distributed. The outside of the spherical limiting block 22 is rotatably connected to the inside of the connecting base 21. The top of the connecting base 21 has a funnel-shaped groove with a larger upper part and a smaller lower part. The outside of the connecting rod 23 is located inside the funnel-shaped groove. The inside of the connecting base 21 has a spherical groove, and the top of the spherical groove fits against the bottom of the funnel-shaped groove.

[0038] Specifically, during installation, the connecting plate 24 is fixed to the outside of the positioning block 31, and the connecting rod 23 is installed between the two connecting plates 24 by rotation. The funnel-shaped groove of the connecting base 21 on the top of the diverter block 4 is aligned with the spherical limiting block 22, and the spherical limiting block 22 slides down along the groove until it is embedded in the spherical groove, completing the assembly of the connecting component 2 and the diverter block 4. During operation, the spherical limiting block 22 rotates freely in the spherical groove, causing the connecting rod 23 to move within the range limited by the funnel-shaped groove, so that the diverter block 4 can adaptively adjust its angle according to the water flow direction, realizing the dynamic dispersion and guidance of the water flow impact force.

[0039] Reference Figures 1 to 3 The reinforcement structure 5 includes two main reinforcement beams 51, which form the skeleton of the reinforcement structure 5 and are directly fixed to the outside of the column base 1. The main reinforcement beams 51 have through holes that can connect with the splicing fixing blocks 38 of the quick-fixing mechanism 3, allowing the entire reinforcement structure 5 to be firmly attached to the surface of the column base 1. The adjacent sides of the two main reinforcement beams 51 are fixedly connected to the outside of the column base 1. Multiple vertical reinforcement blocks 52 are fixedly connected inside the two main reinforcement beams 51. The vertical reinforcement blocks 52 are located inside the main reinforcement beams 51 and form vertical supports through fixed connections, enabling the main reinforcement beams 51 to withstand external forces from different directions. Horizontal reinforcement blocks 53 are fixedly connected to the adjacent sides of the multiple vertical reinforcement blocks 52. The horizontal reinforcement blocks 53 and vertical reinforcement blocks 52 are arranged intersectingly to form a mesh structure, enhancing the stability of the structure. The main reinforcement beams 51 have through holes inside, and the outside of the splicing fixing blocks 38 is slidably connected inside the through holes.

[0040] Specifically, when installing the reinforcement structure 5, the two main reinforcement beams 51 are first fixed to the outside of the column base 1. The splicing fixing block 38 of the quick fixing mechanism 3 is aligned through the through hole inside the main reinforcement beam 51, and the splicing fixing block 38 is slid into the through hole to achieve initial positioning. Then, multiple vertical reinforcement blocks 52 are installed between the two main reinforcement beams 51. The two ends of the vertical reinforcement blocks 52 are fixed to the inside of the main reinforcement beam 51. Then, a horizontal reinforcement block 53 is fixed on the side close to the vertical reinforcement block 52, forming a grid-like reinforcement system composed of the main reinforcement beam 51, the vertical reinforcement block 52 and the horizontal reinforcement block 53, thus completing the structural reinforcement of the column base 1.

[0041] One end of each of the two diversion blocks 4 is provided with a snap-fit ​​groove, and the other end of each of the two diversion blocks 4 is provided with a snap-fit ​​block. The snap-fit ​​block is slidably connected inside the snap-fit ​​groove, and the outside of the connecting bolt 6 is slidably connected inside the snap-fit ​​block. Both diversion blocks 4 are U-shaped ring blocks, and the two diversion blocks 4 are combined into a hexagonal ring block. The edges of both diversion blocks 4 are rounded.

[0042] Specifically, during installation, two U-shaped diverter blocks 4 are placed on either side of the column base 1, aligning the snap-fit ​​block of one diverter block 4 with the snap-fit ​​groove on the other side, and sliding it along the groove until it is fully fitted, forming a hexagonal ring structure. Then, connecting bolts 6 are inserted into the pre-drilled holes in the snap-fit ​​blocks to complete the fixed connection of the two diverter blocks 4. The rounded corners of the diverter blocks 4 at this point allow for a natural transition, and the overall device, through the combined structure of the diverter blocks 4, provides surrounding protection for the column base 1 and guides the water flow.

[0043] The implementation principle of this application embodiment is as follows: two positioning blocks 31 are connected by the mutual cooperation of the splicing fixing block 38 and splicing screw 37 on the top of the positioning block 31. Then, the pressing screw 32 threaded inside the positioning block 31 pushes the pressing block 35 close to the column base 1, so that the friction layer 36 on the wall of the pressing block 35 is in contact with the surface of the column base 1. The friction is increased by the abrasive material of the friction layer 36 itself, thereby avoiding the phenomenon of displacement of the reinforcement device during use, which would ultimately affect the reinforcement effect of the reinforcement device. When the pressing screw 32 located inside the positioning block 31 needs to loosen the restriction on the pressing block 35, the threaded connection between the pressing screw 32 and the positioning block 31 is broken by rotating the pressing screw 32. Then, the release block 33 fixed outside the pressing screw 32 pushes the pressing screw 32 to reset with the help of the return spring 34, thereby loosening the restriction on the pressing block 35.

[0044] The positioning block 31 is connected to the two diversion blocks 4 through the connecting component 2. Specifically, multiple connecting plates 24 fixed to the outside of the positioning block 31 serve as fixing parts for the connecting rod 23, and the other end of the connecting rod 23 is connected to the spherical limiting block 22. The spherical limiting block 22 is rotatably connected inside the connecting base 21, and then connected to the top of the diversion block 4 through the connecting base 21.

[0045] The two diversion blocks 4 are combined to form a hexagonal block, which enables the two diversion blocks 4 to divert the impacting water flow, thereby reducing the impact force generated by the water flow and improving the reinforcement effect.

[0046] Two reinforcing main beams 51 fixed to the outside of the column base 1 serve as main beams. These main beams are connected to multiple vertical reinforcing blocks 52. Multiple transverse reinforcing blocks 53, connected to the vertical reinforcing blocks 52, form a ring with the vertical reinforcing blocks 52, thereby enhancing the efficiency of stress transfer from the column base 1 to the reinforcing main beams 51. Furthermore, the presence of the reinforcing main beams 51 not only enhances the bending stiffness of the column base 1 but also forms an effective stress transfer path between the two diversion blocks 4 and the column base 1, distributing the vertical load more evenly to the surrounding soil and improving the overall bearing capacity of the column base 1.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
