Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a prefabricated floating trestle bridge that can be quickly disassembled, reused, and combined with permanent structures. Background Technology

[0002] With the increasing demand for large-scale cross-river and cross-sea passages, constructing temporary piers in deep-water areas as construction channels has become a primary challenge in bridge construction. Current technologies primarily employ steel piers to ensure the transportation of equipment and materials, involving extensive deep-water piling operations, resulting in complex construction procedures, long construction periods, and poor environmental friendliness. While floating bridges can significantly reduce the difficulty of constructing offshore passages, existing floating bridge technologies still suffer from low modularity, low material utilization, and complex construction procedures, making it difficult to improve the efficiency and economy of temporary construction channels in deep-water bridge construction.

[0003] A floating bridge for easy bridge construction, patent document publication number CN207973987U, includes bearings, pontoons, wear-resistant rubber rings, bridge bodies, connectors, stabilizing buoys, telescopic rods, movable grooves, protective nets, and fixing rods. The bearings are installed in the center of the pontoons with an interference fit. Wear-resistant rubber rings are installed around the pontoons with a circumferential connection. The bridge bodies are installed above the pontoons with a clearance fit. Connectors are installed between the bridge bodies and fixed by welding. The stabilizing buoys are installed on the left side of the telescopic rods and connected by adhesive. The telescopic rods pass through the movable grooves with a clearance fit. However, this patent still has some shortcomings: the bridge bodies need to be welded together through connectors, which slows down the construction efficiency, and it is difficult to disassemble and reuse the floating bridge after the bridge is built. Summary of the Invention

[0004] To address the problems of low construction efficiency and difficulty in reusing temporary trestle bridges during bridge construction, this invention provides a prefabricated floating trestle bridge that combines temporary and permanent structures for rapid disassembly and reuse.

[0005] The technical solution adopted by this invention to solve its technical problem is: a prefabricated floating trestle bridge that can be quickly disassembled and reused for both permanent and temporary applications, including a permanent bridge, the permanent bridge having piers, and a bearing platform fixed on the piers, and also including a frame assembly, combined anti-collision plates, a floating assembly, and a protective assembly. The frame assembly can connect to the bearing platform, and the frame assembly includes multiple fixed bases and an anchoring system. The multiple fixed bases are interconnected by pins, and the anchoring system is fixedly connected to the fixed bases for anchoring the fixed bases. Multiple combined anti-collision plates are provided, each of which is provided with a splicing groove and mounting holes for inserting bolts. The multiple combined anti-collision plates can be spliced ​​together and detachably installed in the fixed bases. The floating assembly includes a main buoy box, which is fixedly connected to the fixed base, and the protective assembly is detachably installed on the main buoy box. Preferably, the fixed base includes an auxiliary pontoon, a fixed frame, a tenon, a pin pre-drilled hole, and a bolt pre-drilled hole. The auxiliary pontoon is integrally formed with the fixed frame and is located on both sides of the bottom of the fixed frame. The lower surface of the auxiliary pontoon is lower than the lower surface of the fixed frame. The tenon is installed on the fixed frame. The pin pre-drilled hole is opened on the end face of both ends of the fixed frame. The bolt pre-drilled hole is opened on the inner bottom of the fixed frame. The pin pre-drilled hole is used to accommodate the pin, and the bolt pre-drilled hole is used to install the combined anti-collision plate.

[0006] Preferably, the mooring system includes multiple anchor cables, each with an anchor fixed to its lower end, and the multiple anchor cables are respectively fixed to the four corners of the fixed base.

[0007] Preferably, the interior of the composite crash barrier uses a composite material lattice web, and the gaps inside the composite crash barrier are filled with cushioning material.

[0008] Preferably, the main float box has a trapezoidal structure that is narrower at the top and wider at the bottom, and the bottom of the main float box has a tenon for fastening and connecting with the protruding tenon.

[0009] Preferably, the protective components include a steel bridge deck and a crash barrier. The steel bridge deck is laid on the upper surface of the main pontoon, and the crash barrier is detachably installed on the edge of the main pontoon. When the crash barrier is removed, it can also be fixed to the permanent bridge to form a road crash barrier.

[0010] Preferably, after the combined crash barrier is removed, it can be reassembled and fixed around the pier to form a ship collision fender. The fixed base of the removed protective components and combined crash barrier can continue to be anchored by the mooring system to form a ship collision passive arresting cable system.

[0011] The beneficial effects of this invention are, firstly, that by assembling multiple fixed bases together with pins and then anchoring them with an anchoring system, the prefabricated floating trestle can adapt to different usage scenarios, effectively improving the efficiency of bridge construction in deep water areas. Secondly, the modular crash barriers are disassembled and reassembled before being fixed to the abutments of permanent bridges as anti-ship collision fenders. The crash barriers can be disassembled and installed as road crash barriers. The fixed base and anchoring system are retained and form a passive anti-ship collision barrier system, realizing the disassembly and reuse of each component, effectively reducing the manpower and material costs in bridge construction.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 10 As shown, this invention provides an embodiment of a prefabricated floating trestle that can be quickly assembled, disassembled, and reused for both temporary and permanent use. It includes a permanent bridge 6 with piers and a support platform fixed to each pier. The trestle also includes a frame assembly, a combined anti-collision plate 7, a floating assembly, and a protective assembly. The frame assembly connects to the support platform. When used as a temporary construction passage, the prefabricated floating trestle connects to the construction platform of the pier via branches constructed using the aforementioned components. Hinged or other detachable connection methods can be used to ensure stable connection and meet the needs of transporting construction materials. The frame assembly includes multiple fixed bases 5 and an anchoring system 1. The multiple fixed bases 5 are interconnected by pins 8, facilitating the assembly or disassembly of the fixed bases 5. The fixed base 5 can be disassembled and assembled in different numbers to adapt to different usage scenarios and improve the construction efficiency of bridges in deep water areas. The fixed base 5 includes an auxiliary pontoon 51, a fixed frame 55, a tenon 53, a pin pre-drilled hole 52, and a bolt pre-drilled hole 54. The auxiliary pontoon 51 is integrally formed with the fixed frame 55 and is located on both sides of the bottom of the fixed frame 55. The lower surface height of the auxiliary pontoon 51 is lower than the lower surface height of the fixed frame 55, which improves the overall stability of the structure. When the attitude of the prefabricated floating bridge tilts, the auxiliary pontoon 51 corrects the attitude of the prefabricated floating bridge through buoyancy, which makes the prefabricated floating bridge less prone to movement, such as reducing the amplitude of swaying, pitching and heaving.

[0018] The tenon 53 is installed on the fixed frame 55. The pin pre-drilled hole 52 is opened on the end face of both ends of the fixed frame 55. The bolt pre-drilled hole 54 is opened on the inner bottom of the fixed frame 55. The pin pre-drilled hole 52 is used to accommodate the pin 8. The bolt pre-drilled hole 54 is used to install the combined anti-collision plate 7.

[0019] The mooring system 1 is fixedly connected to the fixed base 5. The mooring system 1 is used to anchor the fixed base 5 to prevent the prefabricated floating trestle from shifting during the construction of the permanent bridge 6.

[0020] The mooring system 1 includes multiple anchor cables 12, each anchor cable 12 having an anchor 11 fixed at its lower end, and the multiple anchor cables 12 are respectively fixed at the four corners of the fixed base 5.

[0021] Multiple modular crash barriers 7 are provided, each with a splicing groove and mounting holes 10 for inserting bolts. Multiple modular crash barriers 7 can be spliced ​​together and detachably installed in the fixed base 5.

[0022] The interior of the composite crash barrier 7 uses a composite material lattice web, and the gaps inside the composite crash barrier 7 are filled with buffer material, which makes the overall structure of the composite crash barrier 7 watertight, providing additional buoyancy for the assembled floating pier and improving the overall structural rigidity.

[0023] After the combined anti-collision plate 7 is removed, it can be reassembled and fixed around the pier to form a ship collision protection fender. Multiple combined anti-collision plates 7 can be spliced ​​according to the installation space of the fixed base 5 or the shape of the pier, so that the spliced ​​combined anti-collision plate 7 can be installed in the fixed base 5 or fixed around the pier and fits snugly against the pier.

[0024] The floating assembly includes a main float box 2, which is fixedly connected to the fixed base 5. It can also be fixed by spring locks or bolts. As long as the main float box 2 can be stably connected to the fixed base 5 and can also be disassembled, the main float box 2 has a trapezoidal structure that is narrow at the top and wide at the bottom. The bottom of the main float box 2 is provided with a tenon 9 for locking with the tenon 53.

[0025] The protective components are detachably installed on the main pontoon 2. The protective components include a steel bridge deck 4 and a crash barrier 3. The steel bridge deck 4 is laid on the upper surface of the main pontoon 2. The crash barrier 3 is detachably installed on the edge of the main pontoon 2. When the crash barrier 3 is removed, it can also be fixed on the permanent bridge 6 to form a road crash barrier.

[0026] The fixed base 5 of the dismantled protective components and combined anti-collision plate 7 can continue to be anchored by the mooring system 1 and form a passive arresting cable system to prevent ship collisions. In summary, all components of the prefabricated floating trestle can be disassembled and reused on the permanent bridge 6 after the construction of the permanent bridge 6 is completed, which effectively reduces the manpower and material costs in bridge construction. In addition, the combined anti-collision plate 7 can be quickly disassembled and reusable, which can effectively shorten the construction period and has good engineering economy. This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. The above are only preferred embodiments of this application. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the inventive concept and technical solution to other situations without modification, should all be considered within the scope of protection of this application.
