Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of floating bridge construction, in particular to an arc-shaped steel structure floating bridge structure and construction method based on BIM technology. BACKGROUND

[0002] Floating bridge refers to a bridge that uses ships or floating pontoons instead of piers and floats on the water surface, usually with the characteristics of quick disassembly and installation. Floating bridges are facilities or equipment required in real life, production construction, and military operations. In the civil field, most are used for floating piers, aquaculture, etc.

[0003] However, some existing floating bridges are often spliced together in many segments, which is cumbersome to operate, time-consuming and laborious to install and disassemble, and has low efficiency. After connection, the connecting parts are often immersed in water or subjected to water flow impact, causing corrosion and damage, which makes subsequent disassembly and installation inconvenient and causes some trouble for the use of the floating bridge.

[0004] CN217324943U discloses a floating bridge convenient to splice, which comprises a floating bridge plate body, a connecting structure, a rotating rod, a first gear, a second gear, a threaded rod, a threaded groove, a driving rod, a protection structure, and a sealing plug. By rotating the driving rod, the rotating rod is rotated, thereby driving the two first gears, the two second gears, and the two threaded rods to rotate. The threaded rod rotation is threadedly connected with the threaded groove, allowing the two floating bridge plate bodies to approach and abut each other, thereby being tightly connected, facilitating the splicing of the floating bridge plate body. Then, the driving rod is pushed into the interior of the floating bridge plate body, and the sealing plug is covered to protect the driving rod, thereby effectively protecting the driving assembly from water corrosion. Then, the protection structure is used to reinforce the connection stability between the two floating bridge plate bodies, and the sealing plug and the driving rod are protected, greatly improving the protection stability of the driving assembly and facilitating subsequent disassembly and installation work.

[0005] The splicing structure of the above-mentioned technology has the following problems:

[0006] 1) The splicing structure is rigid, which means that the structure components of the floating bridge are tightly connected and lack sufficient elasticity. When a wave surge hits, the floating bridge will be subjected to strong impact and extrusion, causing stress concentration. Long-term or frequent exposure to such stress can easily lead to fatigue fracture or deformation of the structure components.

[0007] 2) The connecting parts used in rigid splicing, such as bolts and welding points, are subjected to excessive shear force and tensile force under wave surge impact, which can easily exceed the carrying capacity of the connecting parts, leading to connection failure or damage.

[0008] 3) The rigidly assembled floating bridge is strictly limited in displacement when subjected to surges. Surges cause unexpected displacement of the floating bridge, but due to the limitation of rigid connection, these displacements cannot be effectively released or buffered, thereby causing damage to the structure.

[0009] 4) Surges cause the entire floating bridge to sway or tilt. Due to the limitation of rigid assembly, the floating bridge cannot effectively adapt to such changes, thereby reducing its overall stability. In extreme cases, it is prone to overturning or disintegration. SUMMARY
