Description

Technical Field

[0001] The present application relates to the technical field of pile foundation reinforcement, and in particular to a pier pile foundation reinforcement structure. Background Art

[0002] A bridge generally consists of a superstructure, a substructure, and ancillary structures. The superstructure primarily refers to the span structure and support system, while the substructure includes abutments, piers, and foundations. Ancillary structures include the bridgehead slab, tapered slope protection, revetments, and diversion works. Bridges are categorized by their structural system into beam bridges. The pile foundations of piers require reinforcement after prolonged use or erosion.

[0003] The patent with announcement number CN216275652U discloses "a pile foundation reinforcement structure, including a fixing sleeve that is sleeved on the lower end of the pile and fixed on the base and at least one oblique support assembly. The fixing sleeve is sleeved on the lower end of the pile and fixed on the upper surface of the base, so that the lower end of the pile is tightened, ensuring the stability of the lower end of the pile. The oblique telescopic mechanism can change the length of the oblique telescopic mechanism, thereby adjusting the tightness of the utility model. When the pile foundation reinforcement structure becomes loose, the pile is tightened by adjusting the length of the oblique telescopic mechanism, ensuring the stability of the pile, so that the stability of the pile is significantly improved, and the service life of the base and the pile structure is extended."

[0004] Regarding the above-mentioned related technologies, the inventor believes that in actual use, it is necessary to first open multiple holes on the base and the column, and then insert one end of the bolt into the hole to install and fix the oblique telescopic mechanism and the fixing sleeve. However, too many holes in the base and the column will prolong the installation time of the reinforcement mechanism, and when the arc-shaped part is fixed on the column, it is also necessary to rotate multiple bolts back and forth, making the overall installation process more cumbersome and inconvenient, and therefore needs to be improved. Utility Model Content

[0005] In order to solve the above problems, the present application provides a pier pile foundation reinforcement structure.

[0006] The bridge pier pile foundation reinforcement structure provided in this application adopts the following technical solutions:

[0007] The pier pile foundation reinforcement structure includes an abutment, a column fixed on the top of the abutment, and a reinforcement mechanism installed between the abutment and the column. The reinforcement mechanism includes two semicircular plates installed on the top of the abutment by bolts, and two reinforcement sleeves fixed on the top of the two semicircular plates for reinforcing the connection between the abutment and the column. A diagonal bracing mechanism is rotatably provided on one side of the top of the semicircular plate. Two sets of arc-shaped members are rotatably provided on the top of the diagonal bracing mechanism to cooperate and abut against the outer wall of the column.

[0008] Two groups of pin rings are fixedly provided on the outer walls of the two semicircular plates. A pin rod which is slidably connected in the arc-shaped member and is inserted into the pin ring is fixedly provided on the top of the pin rod. A counterweight block is fixedly provided on the top of the pin rod.

[0009] By adopting the above technical solution, the two semicircular plates can be installed on the base by bolts, and the two reinforcement sleeves can be used to limit the abutment of the bottom end of the column to reinforce the connection between the column and the base. There is no need to drill holes on the column during reinforcement, thereby reducing the number of holes drilled when installing the reinforcement mechanism and shortening the installation time. The arc-shaped part and the column can be quickly connected and fixed by inserting the pin ring through the pin rod.

[0010] Preferably, the bottom end of the column is fitted and abutted between the two semicircular plates, and the two reinforcement sleeves are fitted and abutted against each other.

[0011] By adopting the above technical solution, the two reinforcement sleeves will form a sleeve structure to cover the bottom end of the column, thereby connecting and reinforcing the connection between the base and the column.

[0012] Preferably, the diagonal support mechanism includes two groups of fixed sleeve rods rotatably arranged on the top of the two semicircular plates and inclined, a threaded rod with a thread arranged in the top of the fixed sleeve rod, and a swivel seat rotatably arranged on the top of the threaded rod, the swivel seat is rotatably connected to the outer wall of the arc-shaped part, a threaded hole is opened on the top of the fixed sleeve rod, the bottom end of the threaded rod is threadedly connected to the threaded hole of the fixed sleeve rod, a swivel plate is fixed on the top of the threaded rod, and the swivel plate is rotatably connected in the swivel seat.

[0013] By adopting the above technical solution, the threaded rod can drive the arc-shaped member to move up and down, so that the arc-shaped member and other structures can laterally support and reinforce the column from different heights, and the scope of application is wide.

[0014] Preferably, a sealing ring for sealing the connection between the threaded rod and the fixed sleeve rod is fixedly provided at the top of the threaded hole of the threaded rod, and a sealing plug is movably provided in the through hole opened at one side of the bottom of the threaded hole of the threaded rod.

[0015] By adopting the above technical solution, the sealing ring and other components can seal the connection between the fixed sleeve rod and the threaded rod, preventing external rainwater from entering the connection between the fixed sleeve rod and the threaded rod and causing the connection to rust, making the threaded rod difficult to rotate, thereby extending the service life of the threaded rod and other components.

[0016] Preferably, a gripping rod is rotatably provided on the outer wall of the threaded rod and is located between the fixed sleeve rod and the rotating seat, and a limiting block is fixedly provided on the outer wall of the top end of the threaded rod and is in contact with the gripping rod.

[0017] By adopting the above technical solution, the staff can hold the handle to drive the threaded rod to rotate, and the limit block can limit the handle so that the handle can only rotate within a certain range on the threaded rod, thereby expanding or folding the handle.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The two semicircular plates can be installed on the base through bolts. With the two reinforcement sleeves abutting and limiting the bottom ends of the columns, the connection between the columns and the base can be reinforced. No holes need to be drilled in the columns during reinforcement, thereby reducing the number of holes drilled when installing the reinforcement mechanism and shortening the installation time. In addition, the lateral support of the columns by the diagonal bracing mechanism and the arc-shaped parts can improve the reinforcement effect of the pier pile foundation. The arc-shaped parts and the columns can be quickly connected and fixed by inserting the pins into the pin rings, without the need to rotate the bolts back and forth, making the overall installation process more convenient and quick.

[0020] 2. By rotating the grip, the threaded rod can be driven to rotate, thereby driving the arc-shaped part to be raised and lowered, so that the arc-shaped part and other structures can laterally support and reinforce the column from different heights. It has a wide range of applications. The sealing ring and other components can seal the connection between the fixed sleeve rod and the threaded rod to prevent external rainwater from entering the connection between the fixed sleeve rod and the threaded rod and causing the connection to rust, making it difficult for the threaded rod to rotate, thereby extending the service life of the threaded rod and other components. The grip can be folded to facilitate the transportation of the diagonal bracing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0028] The embodiments of the present application disclose a pier pile foundation reinforcement structure.

[0029] Pier pile foundation reinforcement structure, refer to Figure 1-3 , including a base 1, a column 2 and a reinforcement mechanism. The column 2 is fixed on the top of the base 1. The base 1 and the column 2 constitute the pile foundation of the existing bridge pier. This is a public technology and will not be described in detail here.

[0030] Reference Figure 1-3 The reinforcement mechanism includes two semicircular plates 3 installed on the top of the base 1 by bolts, and two reinforcement sleeves 31 fixed on the top of the two semicircular plates 3 for reinforcing the connection between the base 1 and the column 2. The bottom end of the column 2 cooperates and abuts between the two semicircular plates 3, and the two reinforcement sleeves 31 cooperate and abut each other. The two semicircular plates 3 cooperate and abut against the outer wall of the bottom end of the column 2. The base 1 can support and fix the two semicircular plates 3 by bolts, where the bolts can be expansion bolts, chemical bolts and other bolts. The two reinforcement sleeves 31 will form a sleeve structure to cover the bottom end of the column 2, thereby connecting and reinforcing the connection between the base 1 and the column 2.

[0031] Reference Figure 1-2 A diagonal bracing mechanism is provided on one side of the top of the semicircular plate 3 for rotation. Two sets of arc-shaped parts 5 are provided on the top of the diagonal bracing mechanism for rotation and abutment against the outer wall of the column 2. The diagonal bracing mechanism and the arc-shaped parts 5 can provide lateral support to the column 2 to further reinforce the pile foundation, thereby improving the reinforcement effect of the pier pile foundation.

[0032] Reference Figure 1 、 Figure 2 and Figure 4The diagonal bracing mechanism includes two groups of fixed sleeve rods 4 that are rotatably arranged at the top of the two semicircular plates 3 and inclined, a threaded rod 41 that is threaded in the top of the fixed sleeve rod 4, and a swivel seat 42 that is rotatably arranged at the top of the threaded rod 41. The swivel seat 42 is rotatably connected to the outer wall of the arc-shaped member 5. A threaded hole 43 is provided at the top of the fixed sleeve rod 4. The bottom end of the threaded rod 41 is threadedly connected to the threaded hole 43 of the fixed sleeve rod 4. A rotating plate 44 is fixed to the top of the threaded rod 41. The rotating plate 44 is rotatably connected to the swivel seat 42. The fixed sleeve rod 4 can support and limit the threaded rod 41 through the threaded hole 43. The rotating plate 44 is in the shape of a circular plate. The rotating plate 44 can connect the threaded rod 41 and the swivel seat 42, so that the threaded rod 41 can rotate at the bottom of the swivel seat 42 without disengaging, and the swivel seat 42 can connect the threaded rod 41 to the arc-shaped member 5.

[0033] After the threaded rod 41 rotates, it will rise and fall under the threaded connection of the threaded rod 41, and cooperate with the connection of the rotating plate 44 to drive the rotating seat 42 and the arc-shaped member 5 and other components to rise and fall. After the arc-shaped member 5 is raised and lowered, it can laterally support and reinforce the column 2 from different height positions, and has a wide range of applications.

[0034] Reference Figure 1 、 Figure 2 and Figure 4 The top of the threaded hole 43 of the threaded rod 41 is fixedly provided with a sealing ring 45 for sealing the connection between the threaded rod 41 and the fixed sleeve rod 4. A sealing plug 46 is movably provided in the through hole opened on one side of the threaded hole 43 at the bottom of the threaded rod 41. The threaded bottom end of the threaded rod 41 is threaded in the sealing ring 45. The sealing ring 45 can be a rubber sealing ring, which is convenient for sealing the connection between the threaded rod 41 and the fixed sleeve rod 4 through elastic extrusion. The sealing ring 45 and the sealing plug 46 can seal the connection between the fixed sleeve rod 4 and the threaded rod 41, preventing external rainwater from entering the connection between the fixed sleeve rod 4 and the threaded rod 41 and causing rust at the connection, which makes the threaded rod 41 difficult to rotate. When the staff rotates the threaded rod 41, they need to remove the sealing plug 46 first, so that outside air can normally enter and exit the threaded hole 43 through the through hole when the threaded rod 41 is raised or lowered, to avoid the air in the threaded hole 43 from being unable to be discharged in time when the threaded rod 41 is lowered, thereby hindering the continued decline of the threaded rod 41.

[0035] Reference Figure 1 、 Figure 2 and Figure 4 The outer wall of the threaded rod 41 is rotatably provided with a grip rod 47 located between the fixed sleeve rod 4 and the rotating seat 42. The outer wall of the top end of the threaded rod 41 is fixed with a limit block 48 that cooperates with the grip rod 47. The staff can hold the grip rod 47 to drive the threaded rod 41 to rotate. The limit block 48 can limit the grip rod 47 so that the grip rod 47 can only rotate within a certain range on the threaded rod 41, thereby expanding or folding the grip rod 47.

[0036] Reference Figure 2 、 Figure 3 and Figure 5 Two sets of pin rings 32 are fixed on the outer walls of the two semicircular plates 3. A pin rod 51 is slidably connected to the arc-shaped part 5 and is inserted into the pin ring 32. A counterweight block 52 is fixed to the top of the pin rod 51. Under the gravity of the counterweight block 52 and other components, the bottom end of the pin rod 51 can be inserted into the pin ring 32, thereby quickly connecting the arc-shaped part 5 and the reinforcement sleeve 31, and then connecting and fixing the arc-shaped part 5 and the column 2 reinforced by the reinforcement sleeve 31.

[0037] The implementation principle of the pier pile foundation reinforcement structure in the embodiment of the present application is:

[0038] During installation, first use bolts to install the two semicircular plates 3 on the base 1, so that the two reinforcement sleeves 31 on the semicircular plates 3 can be against the outer wall of the bottom end of the column 2 after installation. At this time, the two reinforcement sleeves 31 will form a sleeve structure to cover the bottom end of the column 2, thereby connecting and reinforcing the connection between the base 1 and the column 2;

[0039] The staff can then remove the sealing plug 46 and hold the handle 47 to rotate the threaded rod 41. After the threaded rod 41 rotates, it will rise and fall under the threaded connection of the threaded rod 41, and cooperate with the connection of the rotating plate 44 to drive the rotating seat 42 and the arc-shaped member 5 and other components to rise and fall. After the two sets of arc-shaped members 5 are raised and lowered, they can abut against the outer wall of the column 2.

[0040] Then press down the counterweight 52. At this time, under the gravity of the counterweight 52 and other components, the bottom end of the pin rod 51 can be inserted into the pin ring 32 to quickly connect the arc part 5 and the reinforcement sleeve 31, and then the arc part 5 and the column 2 can be connected and fixed. At this time, the diagonal bracing mechanism composed of the fixed sleeve rod 4 and other components and the arc part 5 can laterally support the column 2 to further reinforce the pile foundation, thereby improving the stability of the pier pile foundation after reinforcement.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
