Their main function is to protect bridge pile foundations from external environmental factors such as water erosion, chemical corrosion and physical impact. Reasonable bridge pile foundation protection measures can not only significantly extend the service life of the bridge, but also effectively ensure the safety and stability of the bridge structure.

[0003] In the actual construction process, in order to enhance the tightness of the connection between the fixing rod and the ground, the existing technology usually adopts a variety of means to improve it, such as increasing the insertion depth of the fixing rod, setting spiral blades on the outside of the fixing rod to increase friction, or pouring concrete around the fixing rod to improve the fixing effect.

Summary of the invention

[0007] By adopting the above technical scheme, when it is necessary to protect the pile foundation, first, the protection mechanism is moved to the construction site, the reinforcement assembly is hoisted to the construction area using the lifting mechanism, the pile foundation is hoisted and moved, the pile foundation is inserted into the pile hole, the support plate is fixed to the foundation by the fixing parts, and the two first arc plates clamp the pile foundation. The bridge pile foundation protection device for bridge construction can effectively improve the protection effect of the bridge pile foundation. Specifically, by setting the support plate and the fixing parts in the support assembly, the protection mechanism can be firmly connected to the foundation, thereby providing basic support for the entire protection device; at the same time, the first arc plate in the reinforcement assembly can clamp the pile foundation, and cooperate with the support rod in the support member to further enhance the fixing effect of the protection mechanism on the pile foundation, thereby ensuring the stability and safety of the pile foundation during construction and use.

[0008] In a specific feasible implementation scheme, the fixing device includes an insertion rod, a threaded rod, a slider, a plurality of connecting rods and a plurality of anchor claws, the insertion rod being vertically connected to the side of the support plate close to the foundation, the insertion rod being hollow, and a plurality of insertion holes evenly distributed along its circumference are formed on the peripheral wall of the insertion rod, the threaded rod is sequentially passed through the support plate and the insertion rod, the threaded rod is coaxially arranged with the insertion rod, the threaded rod is sequentially rotatably connected to the support plate and the insertion rod, the slider is threadedly connected to one end of the threaded rod located in the insertion rod, the connecting rod and the anchor claw are both in one-to-one correspondence with the insertion hole, one end of the connecting rod is hinged to the slider, and the other end is hinged to one end of the anchor claw, the other end of the anchor claw can be extended into the insertion hole, and the anchor claw can be inserted into the foundation.

[0009] By adopting the above technical solution, the fixing device can significantly improve the connection stability between the support plate and the foundation, and the specific effects are as follows: the hollow design of the insertion rod and the evenly distributed sockets on the surrounding wall provide space and paths for the anchor claws to unfold; the coordinated use of the threaded rod and the slider makes the unfolding and retracting process of the anchor claws controllable and convenient; under the push of the connecting rod, the anchor claws can extend from the sockets of the insertion rod and penetrate into the foundation to form a stable interlocking structure, thereby greatly enhancing the overall stability of the fixing device, especially under soft or uneven foundation conditions, effectively preventing the fixing device from loosening or slipping, and ensuring the reliable fixation of the bridge pile foundation protection device.

[0010] In a specific possible implementation scheme, the reinforcement also includes two second arc plates and two fastening sources, the first arc plate is hollow, the two second arc plates are distributed along the curvature direction of the first arc plate, the second arc plate is plugged into one side of the first arc plate, the first arc plate and the two second arc plates form a semicircle, the two semicircles form a clamping area for pile foundation placement, the two adjacent second arc plates on the two first arc plates are connected, the second arc plates are slidably arranged on both sides of the first arc plate along the curvature direction of the first arc plate, the fastening source corresponds to the second arc plate, the fastening source is connected to the first arc plate, and the fastening source is used to fix the first arc plate and the second arc plate; The protective mechanism also includes two adjustment components, which correspond to the support plates one by one. The first arc plate is slidably arranged on the top of the support plate. The two first arc plates move toward or away from each other. The adjustment component is connected to the support plate. The adjustment component is connected to the first arc plate to drive the first arc plate to move.

[0011] By adopting the above technical solution, the first arc plate and the second arc plate can be combined to form a semicircular clamping area, which can adapt to pile foundations of different diameters and clamp them firmly, significantly improving the fixing effect of the pile foundation. At the same time, the second arc plate is slidably arranged along the curvature direction of the first arc plate, and the position is locked by the fastening source, making the size adjustment of the clamping area more flexible and convenient. In addition, the adjustment component drives the movement of the first arc plate, further enhancing the adaptability and fixing reliability of the protective device to the pile foundation, and effectively ensuring the construction safety and stability of the bridge pile foundation.

[0012] In a specific feasible implementation scheme, the protective mechanism also includes multiple drainage components, one first arc plate corresponds to one drainage component, and the drainage component includes a drainage plate, and the drainage plate is located on the side of the first arc plate away from the opening. The drainage plate is inclined along the water flow direction from the two second arc plates on the same first arc plate toward away from the first arc plate, and the drainage plate is connected to the first arc plate on the side close to the first arc plate.

[0013] By adopting the above technical solution, the inclined setting of the guide plate can effectively guide the direction of water flow, avoid the accumulation of garbage at the bridge pile foundation, thereby reducing the corrosion damage to the bridge pile foundation caused by harmful substances in the garbage. At the same time, the laminar transition zone formed by the guide plate helps to reduce the amplitude of vortex-induced vibration, reduce the impact of water flow on the protective mechanism, and improve the overall stability and reliability of the protective device.

[0014] In a specific possible implementation scheme, the drainage assembly also includes a rotating rod, and the drainage plate is rotatably connected to the first circular arc plate on the side close to the first circular arc plate, and the drainage plate rotates toward or away from the first circular arc plate. The rotating rod is vertically arranged to the support plate, and both ends of the rotating rod are rotatably connected to the first circular arc plate. The rotating rod can be self-locking, and the drainage plate is connected to the rotating rod on the side close to the first circular arc plate.

[0015] By adopting the above technical solution, the setting of the rotating rod enables the guide plate to rotate around it, so as to adjust the inclination angle of the guide plate relative to the first arc plate. This adjustable design can be flexibly adjusted according to the actual water flow direction and intensity, effectively guiding the water flow direction, avoiding the accumulation of garbage at the bridge pile foundation, and reducing the corrosion damage of harmful substances to the pile foundation. At the same time, the laminar transition zone formed by the guide plate can reduce the amplitude of vortex-induced vibration, reduce the impact force of water flow on the protective mechanism, and improve the stability and reliability of the entire device. In addition, the self-locking function of the rotating rod ensures that the guide plate can remain stable after being adjusted to the appropriate position, further enhancing the protection effect.

[0016] In a specific possible implementation scheme, there are two protection mechanisms; The bridge pile foundation protection device used for bridge construction also includes at least one connecting component, which includes multiple splicing rods, and the multiple splicing rods are all located between two adjacent first arc plates in two adjacent protection mechanisms. The multiple splicing rods are spliced ​​into reinforcement columns, and the splicing rods located at both ends are detachably connected to the first arc plate at one end close to the first arc plate.

[0017] By adopting the above technical solution, two protective mechanisms are set up and multiple splicing rods in the connecting assembly are used to splice into reinforcement columns, which can effectively enhance the connection stability between the two adjacent protective mechanisms and further enhance the stability of the two adjacent pile foundations. Specifically, the setting of the reinforcement column improves the rigidity and impact resistance of the overall structure, ensuring the stability of the protective device in a complex construction environment. At the same time, the detachable connection between the splicing rod and the first arc plate not only facilitates the adjustment of the number and position of the splicing rod according to actual needs, but also simplifies the installation and disassembly process, thereby improving construction efficiency.

[0018] In a specific possible implementation scheme, the connecting assembly also includes a plurality of guide plates, and the plurality of guide plates are all located on the reinforcing column, and the plurality of guide plates are evenly distributed on both sides of the reinforcing column close to the support plate and away from the support plate, and the guide plates located on both sides of the reinforcing column close to the support plate and away from the support plate form a dihedral angle, and the opening of the dihedral angle faces the side away from the water flow, and the guide plates are connected to the splicing rod.

[0019] By adopting the above technical solution, the setting of the guide plate can effectively reduce the impact of water flow on the connecting component. Specifically, multiple guide plates are evenly distributed on both sides of the reinforcing column close to the support plate and away from the support plate. The dihedral design allows the water flow to be guided and diverted when passing through the guide plate, thereby reducing the direct impact force of the water flow on the connecting component. In addition, the structure in which the dihedral opening is facing the side away from the water flow further optimizes the water flow guiding effect, reduces the generation of eddies and turbulence, and improves the overall stability of the protective device.

[0020] In a specific feasible implementation scheme, the fastening source also includes a reinforcement rod and a reinforcement nut, a plurality of reinforcement holes are opened on the side of the first arc plate away from the support plate, and the plurality of reinforcement holes are spaced apart along the curvature direction of the first arc plate, a plurality of fastening holes corresponding to the reinforcement holes are opened on the side of the first arc plate close to the support plate, and a through hole is opened on the second arc plate along a direction perpendicular to the support plate, when the second arc plate moves to a suitable position, the reinforcement rod is successively penetrated through the reinforcement hole, the through hole and the fastening hole, the reinforcement rod is slidingly connected to the first arc plate near the reinforcement hole, the reinforcement rod is threadedly engaged with the first arc plate near the fastening hole, the reinforcement rod can fix the first arc plate and the second arc plate, and the reinforcement nut is threadedly engaged with one end of the reinforcement rod near the reinforcement hole.

[0021] By adopting the above technical scheme, the setting of the reinforcement rod and the reinforcement nut can achieve a stable connection between the first arc plate and the second arc plate. Specifically, a plurality of reinforcement holes distributed along the curvature direction of the first arc plate cooperate with the corresponding fastening holes to provide a precise installation position for the reinforcement rod, ensuring that it can fix the second arc plate at different positions. When the second arc plate is adjusted to a suitable position, the reinforcement rod passes through the reinforcement hole, the through hole and the fastening hole in sequence. The dual design of sliding connection and threaded cooperation not only ensures the flexibility of installation, but also improves the connection reliability. The further locking effect of the reinforcement nut effectively prevents the reinforcement rod from loosening, thereby ensuring the adaptability and stability of the entire reinforcement assembly to pile foundations of different sizes. This design significantly enhances the clamping force and impact resistance of the bridge pile foundation protection device, and improves the safety and durability of the overall structure.

[0022] In a specific possible implementation manner, the end of the insertion rod away from the support plate is configured as a pointed tip.

[0023] By adopting the above technical solution, the resistance when inserting into the ground can be effectively reduced, the insertion efficiency can be improved, and at the same time, it can be ensured that the insertion rod is more firmly fixed in the foundation, thereby enhancing the stability of the overall protective device.

[0024] In a specific possible implementation manner, the fluke is in the shape of an elongated strip, and the outer surface of the fluke is provided with anti-slip teeth.

[0025] By adopting the above technical solution, the contact area with the foundation can be increased and the anchoring effect can be improved. The anti-skid teeth arranged on the outer surface of the anchor claw further increase the friction between the anchor claw and the foundation, especially in soft or uneven foundation conditions, effectively preventing the fixing from loosening or slipping, thereby significantly improving the overall stability and reliability of the bridge pile foundation protection device.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: The designed bridge pile foundation protection device for bridge construction can effectively improve the protection effect of the bridge pile foundation. Specifically, by arranging the support plate and the fixing parts in the support assembly, the protection mechanism can be firmly connected to the foundation, thereby providing basic support for the entire protection device; at the same time, the first arc plate in the reinforcement assembly can clamp the pile foundation, and cooperate with the support rod in the support member to further enhance the fixing effect of the protection mechanism on the pile foundation, thereby ensuring the stability and safety of the pile foundation during construction and use.

[0027] The designed bridge pile foundation protection device for bridge construction, under the push of the connecting rod, the anchor claw can extend from the insertion hole of the insertion rod and penetrate deep into the foundation to form a stable interlocking structure, thereby greatly enhancing the overall stability of the fixings, especially under soft or uneven foundation conditions, effectively preventing the fixings from loosening or slipping, and ensuring the reliable fixation of the bridge pile foundation protection device.

[0028] The designed bridge pile foundation protection device for bridge construction has multiple guide plates evenly distributed on both sides of the reinforcement column close to the support plate and away from the support plate. The dihedral design allows the water flow to be guided and diverted when passing through the guide plates, thereby reducing the direct impact force of the water flow on the connecting components. In addition, the structure with the dihedral opening facing the side away from the water flow further optimizes the water flow guiding effect, reduces the generation of eddies and turbulence, and improves the overall stability of the protection device.

[0045] Reference Figure 5 and Figure 6 In this embodiment, the number of the connecting components 5 is three, and the three connecting components 5 are spaced apart in a direction perpendicular to the support plate 11. The connecting components 5 include a plurality of splicing rods 51 and a plurality of guide plates 52. The plurality of splicing rods 51 are all located between two adjacent first arc plates 211 in two adjacent protective mechanisms. The number of the splicing rods 51 is determined according to the actual situation (the spacing between two adjacent pile foundations). In this embodiment, the number of the splicing rods 51 is three, and the three splicing rods 51 are spliced ​​into a reinforcing column. The reinforcing column is arranged along the distribution direction of the two adjacent first arc plates 211. The reinforcing column is arranged parallel to the support plate 11. The splicing rods 51 at both ends are close to the first arc plate 211 and are detachably connected to the first arc plate 211 by screws, which can be reinforced. The stability of the protective mechanism is strengthened, thereby strengthening the stability of the pile foundation; a connecting column 511 is welded at one end of the middle splicing rod 51, and a connecting hole 512 is opened at the other end for the connecting column 511 on another splicing rod 51 to be inserted, and the connecting column 511 and the connecting hole 512 are detachably connected by a threaded connection. Multiple guide plates 52 are all located on the reinforcement column, and the multiple guide plates 52 are evenly distributed on both sides of the reinforcement column close to the support plate 11 and away from the support plate 11, and the guide plates 52 located on both sides of the reinforcement column close to the support plate 11 and away from the support plate 11 form a dihedral angle, and the opening of the dihedral angle faces the side away from the water flow. The guide plates 52 are welded to the splicing rod 51, which can reduce the impact of the water flow on the connecting component 5 and further increase the stability of the protective mechanism.

[0046] The implementation principle of a bridge pile foundation protection device for bridge construction in an embodiment of the present application is as follows: when the pile foundation needs to be protected, first, the protection mechanism is moved to the construction site, and the adjustment component 3 is started according to the size of the pile foundation. The adjustment component 3 drives the reinforcement component 2 to move, and the first arc plate 211 and the second arc plate 212 move with the reinforcement component 2. Through personnel observation and measurement, until the first arc plate 211 and the second arc plate 212 move to the appropriate position, then, according to the spacing between two adjacent pile foundations, a suitable splicing rod 51 is selected, and the two protection mechanisms are connected through the connecting component 5. The reinforcement component 2 is hoisted to the construction area using a hoisting mechanism, and the pile foundation is hoisted and moved so that the pile foundation is inserted into the pile hole. The support plate 11 is fixed to the foundation by the fixing member 12. At this time, the two protection mechanisms are located in a suitable position, and can accurately place two adjacent pile foundations and make them in a suitable position before construction is carried out.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
