It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0031] like Figures 1 to 4As shown in the embodiment of this application, a vertical construction device for a duct stent is proposed, comprising: four column assemblies 1, each column assembly 1 including at least two columns 101 and a transverse support 102 disposed between two adjacent columns 101, wherein the transverse support 102 and the columns 101 form a triangular region; wherein the four column assemblies 1 are divided into two groups, a proximal support 2 is disposed between the two column assemblies 1 in each group, and a distal support 3 is disposed between the column assemblies 1 in different groups.

[0032] The vertical construction liner device for jacket supports provided in this application embodiment includes four column assemblies 1, a proximal support 2, and a distal support 3. Each column assembly 1 includes at least two columns 101 and a transverse support 102 disposed between two adjacent columns 101. The vertical construction liner device for jacket supports provided in this application embodiment is mainly for providing a construction platform during the vertical assembly of jacket supports. This device not only improves the speed of vertical construction of jacket supports and shortens the construction cycle, but also improves construction safety. In the specific construction process, the location of the jacket support construction layout is first determined, and the liner device is placed at the center of the jacket support to be constructed. Then, a climbing passage and working platform are built at the required height, and safety anchor points are added to the frame. Welding equipment is placed on the working platform. A truck crane is used to connect the main structural pipe components, and personnel perform welding operations on the temporary platform. The use of this device solves the problems of difficult and dangerous high-altitude welding. It creates a wide working space, allowing for simultaneous construction from multiple directions, accelerating the construction process, reducing the use of climbing equipment, and lowering costs.

[0033] The vertical construction liner device for jacket supports provided in this application embodiment, through the arrangement of four column components 1, provides a certain area for the vertical construction liner device for jacket supports, facilitating the construction of access channels and work platforms during subsequent construction. The lateral supports 102, near-end supports 2, and far-end supports 3 enhance the strength of the vertical construction liner device for jacket supports, while also providing more anchoring points. This results in a stable structure and high safety for the vertical construction liner device for jacket supports; it can be reused, reducing the time required to construct temporary work platforms and lowering costs; it provides a relatively stable working environment for personnel, improving welding efficiency and quality; and it facilitates the adjustment of the position of the main structural pipe components, improving the accuracy of jacket support operations.

[0034] The liner device for the guide frame provided in this application is mainly composed of I-beams and large-diameter steel pipes as the skeleton and small-diameter steel pipes as the structure. The structure of the liner device contains many triangular structures to increase its stability and enable it to be used safely for a long time.

[0035] The vertical construction inner liner device for jacket supports provided in this application embodiment is placed at the center of the jacket support construction during use. The main structure is hoisted to the work area by a gantry crane or crawler. During the vertical construction stage of the jacket support main structure, the construction work area is large and the requirements are high. Therefore, this device not only provides a work platform for workers, bringing a stable working environment and safety guarantee, but also meets the real-time debugging and temporary placement of various equipment such as welding and installation operations, improving work efficiency and ensuring work quality and safety.

[0036] like Figures 1 to 4 As shown, in one feasible embodiment, the distal support 3 includes: a plurality of first circular tubes 201, the first circular tubes 201 being welded to the column 101, a portion of the plurality of first circular tubes 201 being arranged horizontally, and another portion of the first circular tubes 201 being arranged crosswise.

[0037] In this technical solution, the structural composition of the remote support 3 is further provided. By selecting multiple first circular tubes 201, the stress on the inner liner device of the guide frame can be more balanced when constructed vertically.

[0038] like Figures 1 to 4 As shown, in one feasible embodiment, the proximal support 2 includes: a plurality of second circular tubes, the second circular tubes being welded to the column 101, some of the second circular tubes being arranged horizontally, and the other part being arranged crosswise; wherein, the length of the first circular tube 201 is greater than the length of the second circular tubes.

[0039] In this technical solution, a structural composition of the distal support 3 is further provided. By selecting multiple second circular tubes, the stress on the inner liner device of the jacket structure can be made more balanced when constructed vertically. The length of the first circular tube 201 is greater than the length of the second circular tube, which allows the inner liner device of the jacket structure to be roughly square in shape, facilitating the processing of the jacket structure.

[0040] In some examples, each column assembly 1 includes three columns 101 and four sets of proximal supports 2, at least some of which are arranged in parallel, which can further improve the strength of the liner device for vertical construction of the liner.

[0041] like Figures 1 to 4 As shown, in one feasible embodiment, the guide frame is constructed using a vertical liner device, and further includes a working platform connected to the column assembly 1. This configuration facilitates the processing of the guide frame by workers. Example

[0042] like Figures 1 to 4As shown, this device was used in a project undertaken by Yangjiang (Offshore Engineering) Equipment Co., Ltd. of China Water Resources and Hydropower Engineering Bureau No. 4. The application of this device reduces the welding difficulty for welding workers and improves their safety during welding. This device provides workers with a stable working environment and safety assurance, offering convenience while also saving materials and construction time for temporary platforms in the construction of jacket structures, thus reducing costs.

[0043] Currently, in the projects the company undertakes, the time spent preparing for temporary setup work has been reduced, thus reducing labor costs. The cost savings comparison analysis is shown in the table below:

[0044] Serial Number plan personnel Working hours (h) Labor cost per hour (RMB) Labor costs (yuan) 1 temporary platform 3 70 50 10500 2 Inner liner device 3 40 50 6000

[0045] Through cost comparison analysis, it was found that 4,500 yuan could be saved for each pipe support produced when using this tooling. In the project, a total of 4 sets of towers used this tooling, saving a total of 18,000 yuan in labor costs.
