[0057] In this embodiment, the trestle support pile connection structure is as follows: Figure 1-2 As shown, it includes: a plurality of vertically spaced steel pipe pile assemblies, the steel pipe pile assemblies are used to support the connecting beam 10, and the steel pipe pile assemblies include:

[0058] Three adjacent first steel pipe piles 20, second steel pipe piles 30, and third steel pipe piles 40 are provided; between the first steel pipe piles 20 and the second steel pipe piles 30, and between the second steel pipe piles 30 and the third steel pipe piles 40, a supporting diagonal rod assembly 50 for maintaining force balance is provided. The supporting diagonal rod assembly 50 includes:

[0059] A first telescopic connecting rod 51, the upper end of which is hinged to the upper end of the first steel pipe pile 20, and the lower end of which is hinged to the lower end of the second steel pipe pile 30;

[0060] A second telescopic connecting rod 52, the upper end of which is hinged to the upper end of the third steel pipe pile 40, and the lower end of which is hinged to the lower end of the second steel pipe pile 30;

[0061] The lower end of the second steel pipe pile 30 is sleeved with a movable assembly 53. The movable assembly 53 includes a movable sleeve 531 sleeved on the second steel pipe pile 30 and capable of moving up and down along the second steel pipe pile 30. The first telescopic connecting rod 51 and the second telescopic connecting rod 52 are symmetrically hinged on the left and right sides of the movable sleeve 531.

[0062] Adjust the position of the movable sleeve 531 on the second steel pipe pile 30 so that it is above the mud surface, so that the lower ends of the first telescopic connecting rod 51 and the second telescopic connecting rod 52 are both above the mud surface;

[0063] The left and right sides of the lower end of the second steel pipe pile 30 are respectively subjected to the forces of the first telescopic connecting rod 51 and the second telescopic connecting rod 52. The second steel pipe pile is subjected to balanced forces in the horizontal direction and is simultaneously subjected to a vertical downward force.

[0064] The left and right sides of the upper end of the first steel pipe pile 20 are respectively subjected to the forces of the second telescopic connecting rod 52 in the previous adjacent steel pipe pile assembly and the first telescopic connecting rod 51 in the current set of steel pipe pile assemblies. The second steel pipe pile 30 is subjected to balanced forces in the horizontal direction and is simultaneously subjected to a vertical downward force.

[0065] The left and right sides of the upper end of the third steel pipe pile 40 are respectively subjected to the forces of the second telescopic connecting rod 52 and the first telescopic connecting rod 51 in the next adjacent steel pipe pile assembly. The third steel pipe pile is subjected to balanced forces in the horizontal direction and is simultaneously subjected to vertical upward forces. Multiple steel pipe pile assemblies are subjected to balanced forces in the vertical direction, providing stable support for the connecting beam 10.

[0066] like Figure 1-3 As shown, the movable assembly 53 further includes an adjustment structure 54 capable of adjusting the movable sleeve 531 to move up and down. The adjustment structure 54 includes:

[0067] A first fixing sleeve 541 is fixed to the upper end of the second steel pipe pile 30. First ear plates 542 are fixedly provided on the left and right sides of the first fixing sleeve 541.

[0068] The left and right sides of the movable sleeve 531 are respectively provided with second ear plates 532;

[0069] A third telescopic connecting rod 55 is arranged between the first ear plate and the second ear plate 532 located on the same side. When the movable sleeve 531 can move, the length of the third telescopic connecting rod 55 is adjusted to become longer, and the movable sleeve 531 moves downward along the second steel pipe pile 30 to fine-tune the position; when the length of the third telescopic connecting rod 55 becomes shorter, the movable sleeve 531 moves upward along the second steel pipe pile 30 to fine-tune the position.

[0070] See also Figure 3-4 The upper end of the wall of the movable sleeve 531 has symmetrical locking grooves 5311 extending vertically downward on both sides. An eccentric locking assembly is provided in the locking groove 5311 to lock and position the movable sleeve 531.

[0071] Specifically, the eccentric locking assembly includes:

[0072] There are two sets of eccentric wheel assemblies 56, which are symmetrically distributed in the locking groove 5311, and each set includes a first eccentric wheel 561 and a second eccentric wheel 562 arranged one above the other;

[0073] The second lugs 532 are provided on both sides of the locking groove 5311, and there are eight of them, and are used to fix one end of the first eccentric wheel 561 and the second eccentric wheel 562;

[0074] The other end of the first eccentric 561 is hinged to the lower end of the third telescopic connecting rod 55. The other end of the first eccentric 561 is also hinged to one end of the connecting rod 563. The other end of the connecting rod 563 is hinged to the other end of the second eccentric 562. The first eccentric 561, the connecting rod 563, the second eccentric 562 and part of the movable sleeve 531 form a four-bar structure. The extension and contraction of the third telescopic connecting rod 55 drives the connecting rod 563, the first eccentric 561 and the second eccentric 562 to move.

[0075] When the movable sleeve 531 moves to the designed position, the third telescopic connecting rod 55 is adjusted to extend, and the first eccentric wheel 561 and the second eccentric wheel 562 rotate counterclockwise around the hinge axis of the second ear plate 532 and clamp the second steel pipe pile 30; when the position of the movable sleeve 531 needs to be adjusted, the third telescopic connecting rod 55 is contracted, and the first eccentric wheel 561 and the second eccentric wheel 562 rotate clockwise around the hinge axis of the second ear plate 532, and the movable sleeve 531 is separated from the second steel pipe pile 30. When the length of the third telescopic connecting rod 55 is adjusted, the movable sleeve 531 is moved along the second steel pipe pile 30, and the position of the movable sleeve is fine-tuned to reduce the installation error and meet the design requirements.

[0076] More specifically, the first eccentric wheel 561 includes an arc-shaped clamping portion 5611 hinged to the second ear plate 532 and a movable portion 5612 hinged to the third telescopic connecting rod 55 or the connecting rod 563;

[0077] like Figure 5 As shown, the radius R1 of the lower structure of the clamping part 5611 is greater than the radius R2 of the upper structure, and the maximum radius of the clamping part 5611 is greater than the shortest vertical distance from the hinge point o of the clamping part 5611 to the outer wall of the second steel pipe pile 30. The clamping part 5611 can clamp the second steel pipe pile 30 and lock the movable sleeve 531 on the second steel pipe pile 30; the second eccentric wheel 562 has the same structure as the first eccentric wheel 561, and the first eccentric wheel 561 drives the second eccentric wheel 562 to rotate through the connecting rod 563; the inner diameter of the movable sleeve 531 is greater than the outer diameter of the second steel pipe pile 30, so that the movable sleeve 531 can move up and down along the second steel pipe pile 30 for fine-tuning of the position.

[0078] In this embodiment, the width of the movable portion 5612 gradually decreases in a direction away from the clamping portion;

[0079] Third ear plates 533 are symmetrically provided on the left and right sides below the movable sleeve 531 , and the first telescopic connecting rod 51 and the second telescopic connecting rod 52 are hinged to the third ear plates 533 respectively.

[0080] Further, such as Figure 1 、 Figure 6 As shown, a second fixing sleeve 21 is provided at the upper end of the first steel pipe pile 20, and a third fixing sleeve 41 is provided at a corresponding position on the upper end of the third steel pipe pile 40;

[0081] The left and right sides of the second fixed sleeve 21 are respectively fixed with fourth ear plates 211, which are hinged to the upper end of the first telescopic connecting rod 51; the left and right sides of the third fixed sleeve 41 are respectively fixed with fifth ear plates, which are hinged to the upper end of the second telescopic connecting rod 52; it is worth noting that the third steel pipe pile 40 in the previous steel pipe pile assembly, as well as the third fixed sleeve 41 and the fifth ear plate on the third steel pipe pile 40, serve as the first steel pipe pile 20, the second fixed sleeve 21 and the fourth ear plate 211 in the next steel pipe pile assembly. Therefore, Figure 6 It is both the third steel pipe pile 40 in the previous steel pipe pile assembly and the first steel pipe pile 20 in the next steel pipe pile assembly.

[0082] In this embodiment, the first telescopic connecting rod 51, the second telescopic connecting rod 52, and the third telescopic connecting rod 55 have the same structure. In order to facilitate adjustment of their lengths, the structure of the first telescopic connecting rod 51 is described as an example. Figure 7 As shown, the first telescopic connecting rod 51 includes:

[0083] A first hinged rod 511, the upper end of which is hinged to the fourth ear plate 211 of the second fixed sleeve, and the lower end of which is provided with a first threaded section 5111;

[0084] The second hinged rod 512 has a lower end hinged to the third ear plate 533 of the movable sleeve 531 and an upper end provided with a second threaded section 5121;

[0085] The adjustment tube 513 is a hollow tubular structure with internal threads. Its ends are connected to the first threaded section 5111 and the second threaded section 5121, respectively. Rotating the adjustment tube 513 changes the length of the first telescopic connecting rod 51, allowing for fine-tuning of the spacing between the steel pipe piles. Notably, in this embodiment, the second articulated rod 512 is longer, with its upper end partially positioned above the water surface. This allows construction personnel to easily operate the adjustment tube 513 from above the water surface, minimizing the need for underwater work.

[0086] like Figure 1As shown, in this embodiment, an I-beam 60 is welded and fixed to the top of the first steel pipe pile 20, the second steel pipe pile 30, and the third steel pipe pile 40. The connecting beam 10 is a Bailey frame, and the I-beam 60 is fixed to the Bailey frame by U-bolts to improve the reliability of the connecting beam.

[0087] In this embodiment, the first fixing sleeve 541, the second fixing sleeve 21, and the third fixing sleeve 41 are all fixed to the steel pipe pile by clamps through bolts. In other embodiments, the first ear plate 542, the fourth ear plate 211, and the fifth ear plate can also be directly welded at the upper end design position of the second steel pipe pile 30, the first steel pipe pile 20, and the third steel pipe pile 40 without the use of a clamp; in addition, the fifth ear plate of the previous steel pipe pile assembly is the fourth ear plate 211 of the next steel pipe pile assembly.

[0088] In the trestle support pile connection structure based on the above technical solution, the movable sleeve 531 is positioned above the mud surface on the second steel pipe pile 30, so that the hinge load-bearing points of the first telescopic connecting rod 51 and the second telescopic connecting rod 52 are both located above the mud surface, reducing the cantilever distance and eliminating underwater welding and cutting processes, thereby improving construction efficiency and reducing costs.

[0089] The first hinged rod 511 and the adjusting pipe 513 are all located above the water surface, which makes it easy for construction workers to operate the adjusting pipe 513 above the water surface, thus reducing underwater operations. At the same time, by adjusting the length of the first telescopic connecting rod 51 and the second telescopic connecting rod 52, the spacing between the steel pipe piles can be fine-tuned to meet the design requirements.

[0090] Adjusting the length of the third telescopic connecting rod 55 can not only fine-tune the position of the movable sleeve 531, but also enable the movable sleeve 531 to clamp the second steel pipe pile 30, thereby achieving stable support for the steel pipe pile while meeting design requirements.

[0091] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0092] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
