Description

Technical Field

[0001] This utility model belongs to the field of high-pile wharf technology, and in particular relates to a reverse hoisting system suitable for high-pile wharf construction. Background Technology

[0002] As a crucial load-bearing structure at the wharf's front edge, the construction technology of high-pile wharf berthing components directly affects the overall performance and service life of the wharf. Currently, three main construction methods are used in engineering practice, each with significant technical limitations.

[0003] The first method is the overall prefabrication and installation process. This involves fabricating components in a land-based prefabrication yard and then using large lifting equipment for overall hoisting. While this method reduces time spent on the water, the large size and complex shape of the components used for mooring the vessel present challenges in controlling their alignment during prefabrication. During installation, environmental factors such as water flow and visibility often make it difficult to guarantee the positioning accuracy of the components, frequently resulting in installation deviations.

[0004] The second method is monolithic cast-in-place construction, which involves casting the concrete entirely on water. While this method ensures the integrity and continuity of the structure, its construction quality is significantly affected by the environment. Tidal changes result in a very limited window of opportunity for work, making it difficult to control the pouring and curing conditions of the concrete. Particularly concerning the support system, traditional cantilevered steel beams exhibit poor stability under wave action, easily deforming and severely impacting construction quality and safety. These problems become even more pronounced in harsh sea conditions.

[0005] The third method is a combination of prefabrication and cast-in-place construction. This method divides the components into underwater prefabrication and above-water casting, but it still presents many challenges in practical applications. During the installation of prefabricated sections, the complex underwater environment makes it difficult to guarantee the positioning accuracy of the components. During the construction of cast-in-place sections, the stability of the support system is poor due to tidal fluctuations. These problems are amplified, especially in sea areas with large tidal ranges, severely impacting structural durability. The technical difficulties of this method mainly lie in several key aspects: precise positioning of the prefabricated sections, stability of the support system for the cast-in-place sections, and quality control during construction.

[0039] The following is a brief description of the construction steps of the anti-lifting system applicable to the construction of high-pile wharves according to this utility model:

[0040] Step 1: After the construction of the dock pile foundation is completed, support frame 1 is arranged in the area where the berthing components are installed. The first support 13 is set in the front load-bearing area of ​​the dock, and the second support 14 is set in the rear support area of ​​the dock, which is used to fix and balance the main beam to be installed later.

[0041] Step Two: After the first support 13 and the second support 14 have passed inspection, the main beam consisting of the first main beam segment 11 and the second main beam segment 12, the first beam assembly, and the second beam assembly are hoisted into place. The main beam is arranged longitudinally along its entire length. The end of the second main beam segment 12 furthest from the first main beam segment 11 is precisely aligned with the center line of the construction area of ​​the berthing component, with a deviation not exceeding 3mm. Subsequently, the first beam assembly and the second beam assembly are installed. The first beam 2 and the second beam 5 are connected to the main beam using 10mm thick node plates. The secondary beams are tightly fitted to the main beam, and the main beam is tightly fitted to the first support 13 and the second support 14 to ensure effective load transfer.

[0042] Step 3: Install two sets of first reverse lifting bolts 3 on the first beam assembly. The first reverse lifting bolts 3 are located at the key stress positions of the berthing component. Each set of first reverse lifting bolts 3 includes two first reverse lifting bolts 3. The four first reverse lifting bolts 3 are arranged in the installation area of ​​the prefabricated part of the berthing component. A reverse lifting bottom beam 4 is installed at the bottom of each set of first reverse lifting bolts 3. The reverse lifting bottom beam 4 provides precise positioning and sufficient fixation and support for the installation of the prefabricated part of the berthing component and the cast-in-place operation platform. Then, based on the positioning of the two reverse lifting bottom beams 4, install the prefabricated part of the berthing component.

[0043] Step 4: Install two second anti-hanging bolts 6 on the second beam assembly. The bracket 7 is composed of longitudinal timber 71, support rod assemblies, and polished wooden boards 75 arranged in layers. The bracket 7 system adopts a layered installation process: first, arrange the longitudinal timber 71 on the second anti-hanging bolts 6; second, install the support rod assemblies on the longitudinal timber 71; finally, install the 20mm thick waterproof polished wooden boards 75 to ensure tight joints in the formwork.

[0044] Step 5, Installation of Template Component 8: According to the shape and size of the berthing components shown in the drawings, cut and assemble 10mm thick polished steel plates 811 as shown in the drawings, and erect them around the reinforcing cage as the outer template 81 and inner template 82. Set 80×80mm wooden vertical ribs on the outside of the outer template 81 and inner template 82, with a spacing of 300mm; arrange two φ10 steel pipes 813 horizontally, with a spacing of 10mm; connect the outer template 81 and inner template 82 into a whole by φ20 precision rolled steel tie rods 84, and tighten the first and third nuts and the fourth nut 86 on the tie rods 84 after installation and positioning.

[0045] Step Six: Concrete is poured in stages using a combination of hoppers and manual labor: The first stage is poured to 2 / 3 of the height of the cast-in-place part of the berthing component. After the concrete strength reaches 75% of the design value, the remaining part of the second stage is poured to ensure the integrity of the structure.

[0046] Step 7: After the concrete reaches the design strength, remove the formwork assembly 8, bracket 7, first anti-hanging bolt 3, second anti-hanging bolt 6, and main beam in sequence to make room for installation and cast-in-place construction in other locations, achieving efficient reuse through repeated cycles. Protective measures should be taken during the removal process to avoid damaging the concrete structure.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
