Description

Technical Field

[0001] This utility model relates to the field of bridge engineering construction technology, and in particular to a bridge pile foundation positioning auxiliary device. Background Technology

[0002] Pile foundations are a crucial load-bearing component in bridge structures, supporting the bridge's own weight as well as dynamic loads from vehicles and pedestrians. They are vital force-transmitting members and a key element in resisting seismic forces, significantly impacting the bridge's load-bearing capacity and safety. Their construction quality directly influences and constrains the overall construction progress, cost, and quality of the entire project.

[0003] A typical bridge pile foundation positioning auxiliary device consists of a positioning mechanism, an adjustment structure, and a support mechanism. The positioning mechanism determines the initial positioning benchmark of the pile foundation design coordinates, the adjustment structure adjusts the positioning deviation with the help of a hydraulic system, and the support mechanism is fixed to the foundation with rigid brackets to provide stable support for the adjustment structure.

[0004] The accuracy of the positioning and the stability of the fixed pile foundations in some of the above-mentioned technologies are directly related to the load-bearing capacity and service life of the bridge. When the pile foundation is adjusted within the positioning frame, the existing devices often lack multi-dimensional limiting mechanisms, which makes it impossible to effectively constrain the movement of the pile foundation in the horizontal and vertical directions. This makes it difficult for construction personnel to accurately control the overall position of the pile foundation, and it is easy for the positioning deviation to exceed the standard. Therefore, a bridge pile foundation positioning auxiliary device is proposed to solve the above problems. Utility Model Content

An adjusting rod is threadedly connected to the inside of each mounting block. A supporting base plate is threadedly connected to the outside of the plurality of adjusting rods. A plurality of extension components are slidably connected to the inside of the supporting base plate.

[0008] As a further description of the above technical solution:

[0035] The positioning mechanism 2 includes multiple connecting plates 21. The connecting plates 21 enable the fixed installation of the positioning mechanism 2 on the foundation 1 and provide a connecting carrier for multiple connecting side plates 22. The bottom of the multiple connecting plates 21 is threaded to the top of the foundation 1. Connecting side plates 22 are fixedly connected to the adjacent side of the connecting plates 21. The connecting side plates 22 form the side of the positioning frame and provide the installation position. The two ends of the adjacent side of the connecting side plates 22 are threaded to the snap-fit ​​posts 23. The snap-fit ​​posts 23 connect the connecting side plates 22 and the snap-fit ​​side plates 24 to achieve the lateral connection of the positioning frame. The adjacent side of the snap-fit ​​posts 23 is fixedly connected to the snap-fit ​​side plates 24. The snap-fit ​​side plates 24 and the connecting side plates 22 together form the four-sided structure of the positioning frame, which laterally limits and positions the pile foundation to ensure that the pile foundation maintains the correct position during construction. The internal threads of the connecting plates 21 are connected to the assembly bolts 25. The assembly bolts 25 penetrate the interior of the connecting plates 21 to assemble the multiple connecting plates 21 and the connecting side plates 22 into a whole to ensure the structural stability of the positioning frame.

[0036] Mounting blocks 26 are fixedly connected to both sides of the inner side of the connecting side plate 22. The mounting blocks 26 provide the mounting and support positions for the adjusting rods 27, so that the adjusting rods 27 can accurately clamp and position the base column 4.

The interior of the multiple connecting pipes 291 is slidably connected to the exterior of the support base plate 28, and the positioning plate 292 is fixedly connected to the exterior of the multiple connecting pipes 291. The positioning plate 292 disperses pressure by increasing the contact area, thereby achieving stable positioning and support for the reinforcing bars 293. The interior of the connecting pipes 291 is slidably connected to the reinforcing bars 293. The reinforcing bars 293 enhance the connection strength between the support base plate 28 and the foundation 1, improving the overall stability and pull-out resistance of the device.

The square tube 34 cooperates with the connecting rod 33 and the support ring 32 to enhance the overall support strength of the support mechanism 3. A shaft core 35 is fixedly connected externally to the connecting rod 33. The shaft core 35 provides a rotation support shaft for the hook 36, allowing the hook 36 to rotate around the shaft core 35. The hook 36 is rotatably connected externally to the shaft core 35. The hook 36 rotates around the shaft core 35. The outer inner side of the hook 36 is supported on the top of the support tube 31, and the far side of the square tube 34 is supported on the outer inner side of the support ring 32.

[0039] Multiple connecting holes 5 are provided on the inner side of the top of the foundation 1. The connecting holes 5 are used to install steel bars 293. The foundation column 4 is slidably connected inside the foundation 1. The foundation column 4 serves as the main structure of the bridge pile foundation. It is inserted into the foundation 1 and cooperates with the positioning mechanism 2 and the support mechanism 3 to achieve accurate positioning and fixation of the pile foundation. One end of the steel bar 293 is supported inside the connecting hole 5. The bottom of the support base plate 28 is fixedly connected to the top of the foundation 1.

The mounting block 26 is fixed inside the connecting side plate 22 on both the upper and lower sides. The adjusting rod 27 is threaded into the mounting block 26. Rotating the adjusting rod 27 can make it press against the base column 4 to achieve the positioning and limiting of the base column 4. The support base plate 28 is fixed to the top of the foundation 1. The connecting pipe 291 slides inside the support base plate 28, driving the positioning plate 292 to adjust its position to adapt to the base column 4. The reinforcing bar 293 slides inside the connecting pipe 291 and is inserted into the connecting hole 5 of the foundation 1 to enhance the connection strength between the support base plate 28 and the foundation 1.
