Technical Field
[0001] This utility model belongs to the field of steel pipe pile construction technology, specifically relating to a construction guidance device for deep-water interlocking steel pipe piles. Background Technology
[0002] When constructing interlocked steel pipe piles in deep water environments, water flow velocity, wave impact, and underwater currents can cause the steel pipe piles to deviate from their designed position during pile driving. If the pile body tilts, the interlocks between the steel pipe piles cannot be effectively connected, leading to reduced structural strength or leakage risks. Therefore, measures need to be taken to prevent the steel pipe piles from deviating from their designed position during pile driving.
[0003] In the prior art, such as the Chinese invention patent application with publication number CN112302020A, a guiding device for the first pile driving construction of a large interlocking steel pipe pile cofferdam is disclosed. However, it is only applicable to steel pipe piles of one specification. In different projects, the outer diameter of the steel pipe piles varies. The above-mentioned prior art is not convenient for reuse and requires the production of corresponding guiding devices according to the outer diameter of different steel pipe piles, which increases the construction cost.
[0004] Therefore, it is necessary to design a construction guidance device for deep-water interlocking steel pipe piles that can match various outer diameters within a certain range, thereby expanding the scope of application and reducing construction costs, in order to solve the current technical problems. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this utility model provides a construction guidance device for deep-water interlocking steel pipe piles that can match various outer diameters within a certain range, thereby expanding the scope of application and reducing construction costs.

[0025] like Figures 1 to 4As shown, the construction guide device for deep-water interlocked steel pipe piles includes a support plate 1 arranged parallel to each other vertically. A pile driving hole 11 is opened in the middle of the support plate 1. A self-centering positioning mechanism 4 is provided on the top of the support plate 1 corresponding to the pile driving hole 11. Support columns 2 are evenly arranged between the two support plates 1. Support beams 3 are fixedly installed on the support columns on both sides of the support plate 1.

The middle of the support arms 42 is rotatably connected to the support plate 1. A mechanism is provided on the support plate 1 to drive the support arms 42 away from the pile driving hole. The swing arm adjustment assembly moves synchronously and in the same direction at one end of the center of hole 11. In this embodiment, the self-centering positioning mechanisms 4 on the two support plates 1 correspond to each other. During the pile driving process, they can provide two support points for the steel pipe pile, keep the steel pipe pile vertical, avoid the pile body tilting, and ensure the construction quality of the steel pipe pile. The swing arm adjustment assembly can synchronously control the movement and adjustment of the support arm 42, thereby changing the diameter of the virtual circle formed by the end of the support arm 42 to match the outer diameter of the steel pipe pile. During the pile driving process, it supports and guides the steel pipe pile, and can match steel pipe piles with various outer diameters within a certain range, thereby improving the application range and reducing construction costs.
[0026] In some embodiments, the self-centering positioning mechanism 4 has four support arms 42 arranged in a circular array on top of the tray 1.
[0027] In some embodiments, the support plate 1 is a square steel plate, the pile hole 11 is a central hole starting in the center of the support plate 1, and a support column 2 is vertically welded between the four corners of the two support plates 1. The support column 2 and the support beam 3 are both made of square steel, and the support beam 3 is vertically welded and fixed to the support column 2.
[0028] In some embodiments, the swing arm adjustment assembly has a slewing bearing 41 fixedly mounted concentrically on the top of the support plate 1 with the pile driving hole 11.

One end of the support arm 42 is rotatably and slidably connected to the outer ring 412. The support plate 1 is provided with an adjustment component 46 for driving the outer ring 412 to rotate and adjust. By adjusting the length of the adjustment component 46, the adjustment component 46 can drive the outer ring 412 to rotate outside the inner ring 411, thereby moving one end of the support arm 42 that is rotatably and slidably connected to the outer ring 412, thereby changing the diameter of the virtual circle formed by the end of the support arm 42 to match the outer diameter of the steel pipe pile.

[0031] In some embodiments, a groove 421 is provided on one end of the support arm 42 near the outer ring 412. A slide rod 44 is rotatably and slidably disposed inside the groove 421. The bottom end of the slide rod 44 is fixedly disposed on the top of the outer ring 412, and a limit plate 45 is fixedly disposed on the top end of the slide rod 44. When the outer ring 412 is rotated and adjusted, the slide rod 44 can move inside the groove 421, pushing the support arm 42 to swing.
[0032] In some embodiments, a guide post 43 is fixedly provided on one end of the support arm 42 near the pile driving hole 11. The axis of the guide post 43 is parallel to the axis of the pile driving hole 11. During pile driving, the outer side of the guide post 43 contacts the outer side of the steel pipe pile.
[0033] In some embodiments, a cone 431 is fixedly provided at the top of the guide post 43, with the smaller end of the cone 431 facing upwards.
