Description

Technical Field

[0001] The present invention relates to the technical field of pipe pile repair, and in particular to a pipe pile foundation reinforcement and repair device. Background Art

[0002] Concrete pipe piles are made using a pre-tensioned prestressed centrifugal forming process and are steam-cured at 10 atmospheres of pressure and around 180°C to form a hollow cylindrical concrete precast component. Serving as the foundation of bridge piers in bridge projects, they have the characteristics of strong bearing capacity and good seismic resistance.

[0003] When used as the foundation for bridge piers, pipe piles are subject to constant pressure from the bridge's loads, and they may also face the risk of accidental collisions with ships or impacts from floating objects on the water. Furthermore, due to long-term exposure to water, pipe piles must also withstand various types of erosion. Under the influence of various environments, pipe piles will gradually develop cracks and even form damaged openings after long-term use. Collision accidents are more likely to expose and fracture the steel reinforcement structure inside the pipe piles, thereby seriously weakening the overall bearing capacity of the concrete pipe piles. Traditionally, damaged openings in pipe piles are often repaired using reinforcement and repair devices for the pipe pile foundation.

[0004] Existing pipe pile foundation reinforcement and repair devices typically rely on a clamp tube assembly and a support assembly to create a grouting area with the pipe pile. Concrete slurry is then poured from the top to partially repair the damaged portion of the pipe pile. However, this method has several drawbacks: the grouting area is extensive and covers a large surface area, which not only increases the overall weight of the repaired pipe pile but also may alter the original external profile of the pipe pile, thereby weakening its load-bearing capacity. Furthermore, given the hollow structure of the pipe pile, there is a risk of excessive inflow of concrete slurry during the grouting process, which not only wastes material but also has a negative impact on the internal structure of the pipe pile.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention and are not to be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0019] The following describes a device for reinforcing and repairing a pipe pile foundation according to an embodiment of the present invention with reference to the accompanying drawings.

[0020] like Figures 1-8 As shown, the reinforcement and repair device for the pipe pile foundation according to the embodiment of the present invention includes a repair seat 1, a reinforcement semi-ring sleeve 2, a blocking mechanism 3, a repair covering plate 4 and an adjustment mechanism 5.

[0021] The reinforcing semi-annular sleeve 2 is arranged on one side of the repair seat 1 , and a pipe pile foundation 21 is arranged between the repair seat 1 and the reinforcing semi-annular sleeve 2 , and a broken opening is opened on the pipe pile foundation 21 .

[0022] It should be noted that the repair seat 1 and the reinforcement semi-ring sleeve 2 are rotatably connected, and a lock connection is provided to facilitate the sleeve on the pipe pile foundation 21 to ensure a stable state during repair. The damaged opening is the damaged opening of the pipe pile foundation 21, on which there is a steel bar structure, and there are gaps between the steel bar structures to facilitate the wrapping of concrete slurry.

[0023] The blocking mechanism 3 is arranged on the repair seat 1 , and the blocking mechanism 3 includes a movable bar seat 31 , two arc-shaped baffles 32 and an expansion driving structure 33 .

[0024] Among them, the movable bar seat 31 is plugged into the repair seat 1 and the damaged mouth, the two arc-shaped baffles 32 are rotatably set on one side of the movable bar seat 31 located in the pipe pile foundation 21, and the expansion drive structure 33 is set on the movable bar seat 31 and connected to the two arc-shaped baffles 32.

[0025] It should be noted that the movable bar seat 31 is a slender bar support structure, which can easily pass through the gaps between the steel bars. Two arc-shaped baffles 32 that can be rotated and expanded are arranged on it through the unfolding driving structure 33. After the movable bar seat 31 passes through the steel bar gap and enters the interior of the pipe pile, the arc-shaped baffle 32 is unfolded to seal the inner area of ​​the damaged mouth, ensuring the formation when pouring concrete slurry, and at the same time avoiding the waste of concrete slurry flowing into the interior of the pipe pile.

[0026] Among them, the repair covering plate 4 is arranged on the repair seat 1 and is sleeved on the movable bar seat 31. The repair covering plate 4 is connected to the outer wall of the pipe pile foundation 21. Grouting pipes 41 are inserted on both sides of the repair covering plate 4, and the top of the grouting pipe 41 extends to the outside and above the repair seat 1.

[0027] It should be noted that the repair covering plate 4 can fit the outer surface of the pipe pile, limit the poured concrete slurry, prevent the concrete slurry from overflowing and solidifying, ensure that the shape of the pipe pile after repair is not deformed, and ensure the quality of the repair. The two grouting pipes 41 extend to the top to facilitate the pouring of concrete slurry from the top for repair.

[0028] The adjusting mechanism 5 is arranged on the repair seat 1 and is connected to the movable bar seat 31 .

[0029] It should be noted that the adjustment mechanism 5 can drive the movable strip seat 31 to move and control its entry and exit of the damaged opening. After the damaged opening is repaired, the adjustment mechanism 5 can be used to control the movable strip seat 31 to escape from the damaged opening, and continue to grout the last smaller strip aperture to repair, thereby reducing concrete waste and ensuring the quality of the repair.

[0030] Among them, lifting buckles 22 are provided on both sides of the reinforcement half ring 2.

[0031] It should be noted that the lifting buckle 22 is set on the reinforcement half ring 2, and can be connected to an external lifting component to control the entire repair device to move up and down on the pipe pile, making it convenient to move to the damaged area for repair work.

[0032] Specifically, when the pipe piles of the bridge piers are damaged by erosion and impact, the relevant staff will put the repair seat 1 and the reinforcement half ring 2 on the pipe pile and fix them, connect the lifting assembly through the lifting buckle 22, control the entire repair device to rotate and move downward, and stop after moving to the damaged position.

[0033] The operation adjustment mechanism 5 drives the movable bar seat 31 to pass through the steel structure and enter the pipe pile. At this time, the expansion drive structure 33 is controlled to control the two arc baffles 32 to expand. At the same time, the movable bar seat 31 moves outside the pipe pile to tighten the arc baffle 32. After the adjustment is completed, the relevant staff continuously injects concrete slurry into the damaged opening through the grouting pipe 41 on the top for repair.

[0034] After the repair area is dry and solidified, the driving structure 33 is operated to retract the two arc-shaped baffles 32, and the adjusting mechanism 5 is re-operated to control the movable bar seat 31 to separate from the pipe pile. At this time, only the area of ​​the movable bar seat 31 and the smaller damaged opening are left in the repair area. The hoisting component control device is rotated in a certain direction so that the grouting pipe 41 can be aligned with the damaged opening and the grouting is re-administered to the inside for repair. Since the remaining damaged opening is small and has steel bars blocking it, the concrete slurry is viscous. Pouring at this time can avoid the waste of concrete slurry flowing in, and complete the final damaged opening repair. After the repair is completed, the reinforcement repair device is disassembled to complete the repair and reinforcement work of the pipe pile.

[0035] In one embodiment of the present invention, Figure 2 、 Figure 6 、 Figure 7 and Figure 8 As shown, the unfolding drive structure 33 includes two driven gears 331 , two driving gears 332 , a worm gear 333 , a worm 334 and a first driver 335 .

[0036] Among them, the two driven gears 331 are respectively set on the corresponding arc-shaped baffles 32, and a driving groove is opened on the movable bar seat 31. The two driving gears 332 are rotatably set in the driving groove and are meshed with each other. The two driving gears 332 are meshed with the corresponding driven gears 331.

[0037] It should be noted that the two driving gears 332 are meshed with each other and can be conventional to each other, and the two driving gears 332 correspond to two driven gears 331, controlling the two driven gears 331 to rotate in opposite directions, and finally controlling the two arc-shaped baffles 32 to rotate in opposite directions, realizing the function of expanding and contracting.

[0038] In order to clearly illustrate the above embodiment, in one embodiment of the present application, Figure 6 and Figure 8 As shown, the worm wheel 333 is rotatably set in the driving groove and is connected to the driving gear 332, the worm 334 is rotatably set in the driving groove and is meshed with the worm wheel 333, and the first driver 335 is set at one end of the worm 334 and inserted into the movable bar seat 31.

[0039] It should be noted that the first driver 335 can be a servo motor connected to the worm 334. The worm 334 can drive the worm wheel 333 to rotate to drive the driving gear 332. At the same time, the worm 334 drives the worm wheel 333 to have a self-locking ability, which can ensure the stability of the arc baffle 32 after it is turned open, and will not be squeezed and impacted by the concrete slurry and retracted, thereby ensuring the stability of the structure.

[0040] Specifically, after the movable bar seat 31 enters the pipe pile and passes through the steel structure, the first driver 335 is operated to drive the two arc-shaped baffles 32 to rotate and expand, sealing the inside of the damaged opening, and then grouting repair is performed to ensure the shaping effect of the repair position and the quality of the repair.

[0041] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, the adjustment mechanism 5 includes a frame seat 51 and a control structure 52.

[0042] The frame seat 51 is disposed on the repair seat 1 and is sleeved on the movable bar seat 31 . The control structure 52 is disposed on the frame seat 51 and is connected to the movable bar seat 31 .

[0043] It should be noted that the frame seat 51 can support and guide the movable bar seat 31 to ensure the stability of its movement, and the control structure 52 can control the movement of the movable bar seat 31.

[0044] In order to clearly illustrate the above embodiment, in one embodiment of the present application, Figure 1 、 Figure 5 and Figure 6 As shown, the control structure 52 includes a rack 521 , an adjustment gear 522 and a second driver 523 .

[0045] Among them, an adjustment groove is opened at the bottom of the frame seat 51, the rack 521 is set at the bottom of the movable bar seat 31, the adjustment gear 522 is rotatably set in the adjustment groove and is engaged with the rack 521, and the second driver 523 is set at one end of the adjustment gear 522 and is inserted into the frame seat 51.

[0046] It should be noted that the second driver 523 can be a servo motor, which is connected to the adjusting gear 522 to control its rotation, and then drive the rack 521 to drive the movable bar seat 31 to move on the frame seat 51. At the same time, the number of rotations of the second driver 523 is limited and can be connected to the controller for control to ensure that the movable bar seat 31 will not separate from the frame seat 51. In addition, a limit block is also provided on the frame seat 51, and a limit groove is opened on the corresponding movable bar seat 31 to prevent the two from separating and the structure from falling apart.

[0047] Specifically, when it is necessary to control the movable bar seat 31 to enter or leave the pipe pile, the relevant staff operates the second driver 523 to drive the adjusting gear 522 to drive the rack 521 and the movable bar seat 31 to move, thereby realizing the function of entering and exiting the damaged opening of the pipe pile.

[0048] In summary, the reinforcement and repair device for the pipe pile foundation of the embodiment of the present invention can repair the damaged area of ​​the pipe pile, ensuring the quality of the repair while avoiding changing the shape and weight of the pipe pile, and at the same time seal the inside of the damaged mouth to avoid the waste of a large amount of concrete slurry flowing in, thereby ensuring the repair quality of the pipe pile.
