Description

Technical Field

[0001] The utility model relates to the technical field of trestle construction, in particular to a trestle steel pipe pile sinking guide frame. Background Art

[0002] With the rapid development of my country's economy, transportation modes such as railways and urban rail transit have developed rapidly. When building kilometers or railways across lakes, rivers, and seas, it is usually necessary to build a trestle as a construction channel. However, the positioning accuracy of the steel pipe piles of the trestle is a major technical problem in the construction process. If the positioning accuracy of the steel pipe piles of the trestle is not enough, the stability of the trestle will be poor, affecting the safety of construction. Summary of the invention

[0003] In order to solve the above problems, the utility model aims to provide a pile sinking guide frame for trestle steel pipe piles.

[0004] A guide frame for sinking steel pipe piles on a pier, comprising a guide platform, wherein the guide platform comprises a pair of first longitudinal bars arranged longitudinally and a plurality of second transverse bars arranged transversely between the pair of first longitudinal bars, wherein the first longitudinal bars and the second transverse bars are staggered to form a square guide opening for inserting the steel pipe piles, and the side length of the guide opening matches the outer diameter of the steel pipe piles; the bottom of the guide platform is fixed to the front end of a Bailey beam by a transversely extending bracket, and the guide platform as a whole is located below the extension plane of the Bailey beam.

[0005] Preferably, the transversely extending bracket includes a vertical connecting rod and a transverse connecting rod arranged in an "L" shape, the vertical connecting rod is fixed to the front end of the Bailey beam, and the guide platform is fixed on the transverse connecting rod.

[0006] Preferably, the first longitudinal rod, the second cross rod, the vertical connecting rod and the transverse connecting rod are I-beams, and the guide platform and the Bailey beam are connected by bolts.

[0007] Preferably, the guide platform and the transversely extending bracket are temporarily fixed by welding.

[0008] Preferably, the guide platform comprises a fence arranged around the periphery of the platform defined by the first longitudinal rod and the first transverse rod.

[0009] In the above scheme, the steel pipe piles of the trestle can be guided by the guide opening of the guide frame arranged at the front end of the Bailey beam, and the structure and installation method of the guide frame are very simple, which is conducive to saving construction costs. And the guide platform is located below the extension plane of the Bailey beam as a whole. Compared with the scheme in the prior art where the guide frame is directly fixed on the Bailey beam, this arrangement can sink the pile to the designed pile top elevation at one time, without the need to dismantle the Bailey beam 3 for a second time, and lift the vibrating hammer to sink the pile again to the designed elevation, saving construction time and reducing the safety risk during the disassembly and assembly process.

[0013] A guide platform 1, a first longitudinal rod 11, a second transverse rod 12, a fence 13, a guide opening 14, a transverse extension bracket 2, a vertical connecting rod 21, a transverse connecting rod 22, a Bailey beam 3, and a steel pipe pile 4. DETAILED DESCRIPTION

[0014] The embodiments of the present utility model are described in detail below.

[0015] This embodiment provides a guide frame for sinking steel pipe piles of a trestle bridge, such as Figure 1 and Figure 2 As shown, the guide frame includes a guide platform 1, and the guide platform 1 includes a pair of first longitudinal bars 11 arranged longitudinally and a plurality of second transverse bars 12 arranged transversely between the pair of first longitudinal bars 11. The first longitudinal bars 11 and the second transverse bars 12 are staggered to form a guide opening 14 for inserting the steel pipe pile 4, and the radial dimension of the guide opening 14 matches the outer diameter of the steel pipe pile 4. During construction, the steel pipe pile 4 is inserted into the guide opening 14 to guide the sinking of the steel pipe pile 4. The bottom of the guide platform 1 is fixed to the front end of the Bailey beam 3 through the transverse extension bracket 2, and the guide platform 1 is located below the extension plane of the Bailey beam 3 as a whole. Compared with the solution in the prior art that the guide frame is directly fixed on the Bailey beam 3, this arrangement can sink the pile to the designed pile top elevation at one time, without the need to dismantle the Bailey beam 3 for a second time, and lift the vibrating hammer to sink the pile again to the designed elevation, saving construction time and reducing the safety risk of the disassembly and assembly process. In the embodiment, the transverse extension bracket 2 includes a vertical connecting rod 21 and a transverse connecting rod 22 arranged in an "L" shape. The vertical connecting rod 21 is fixed to the front end of the Bailey beam 3 and extends along the height direction of the Bailey beam 3. The guide platform 1 is fixed on the transverse connecting rod 22. Through the above-mentioned L-shaped transverse extension bracket 2, the guide platform 1 can be set on the front side and the lower side of the Bailey beam 3, and the structure of the transverse extension bracket 2 is simple. The transverse connecting rod 22 and the vertical connecting rod 21 can be selected from I-beams. A pair of I-beams can provide stable support for the guide platform 1. Figure 1As shown, A indicates the installation height of the conventional guide structure in the prior art, which is flush with the Bailey beam 3, and B indicates the pile top elevation. It can be seen from the figure that the pile top elevation is lower than the Bailey beam 3. If the guide structure is flush with the Bailey beam 3, the pile cannot be sunk to the designed pile top elevation in one go during the pile sinking process, so there will be a repeated disassembly and assembly process of the Bailey beam 3. In this solution, the guide platform 1 is fixed by the transverse extension bracket 2, and the length of the vertical connecting rod 21 and its fixed height at the front end of the Bailey beam 3 can be set appropriately, so that the guide platform 1 can be flush with the pile top elevation or located below the pile top elevation, thereby achieving one-time pile sinking.

[0016] Preferably, the first longitudinal rod 11, the second cross rod 12, the vertical connecting rod 21 and the transverse connecting rod 22 are I-beams, and the guide platform 1 is connected to the Bailey beam 3 by bolts. The I-beams are selected, on the one hand, the strength of the profile itself can be guaranteed, and on the other hand, the connecting holes between the I-beams are convenient to process and connect by bolts, which is convenient for connection.

[0017] The guide platform 1 is temporarily welded and fixed to the transverse extension bracket 2, and is easy to remove after the pile driving construction is completed at the current position. The guide platform 1 includes a circle of fences 13 arranged around the outer periphery of the platform defined by the first longitudinal rod 11 and the first transverse rod. During the later construction process of the pile driving construction, the construction personnel need to be able to improve the operation safety when operating the guide platform 1.

[0018] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
