Embodiment 2

[0070] On the basis of Embodiment 1, a method for erecting a tied arch pontoon bridge provided by this embodiment includes the following steps:

[0071] S001: Before air-dropping the floating structure 6 and the hoisting structure 6 as a whole or in sections to the predetermined water area, first splicing multiple floating tank units 61 on the level ground through the bolt 65 to form the floating body structure 6, and then placing the hoisting structure on the floating body structure 6 surface together for air transport;

[0072] S002: Lift the floating body structure 6 and the hoisting structure to the release site as a whole by helicopter: After the floating body structure 6 is dropped into the designated water area, first set up anchoring structures on both sides of the floating body structure 6, and then place anchor structures on the four corners of the floating body structure Pull out the mooring steel cable along the direction of 30° from the floating body on both sides...

Abstract

The invention provides a tied-arch floating bridge and a tied-arch floating bridge erecting method, and relates to the technical field of civil engineering. The tied-arch floating bridge comprises a floating body structure, a hoisting structure and arch abutment support seats, the hoisting structure is arranged above the floating body structure and capable of hoisting the floating body structure, the hoisting structure comprises at least two main arch bodies, a plurality of cross supports, a plurality of perpendicular hoisting rods and a plurality of tie rods, two ends of main arch bodies are fixedly connected with the arch abutment support seats respectively, every two main arch bodies are connected with each other through the transverse supports, top portions of the perpendicular hoisting rods are connected with the main arch bodies, bottom portions of the perpendicular hoisting rods are connected with the floating structure, rod bodies of the tie rods are connected with the perpendicular hoisting rods which are mounted on the corresponding main arch bodies, and rod ends of the tie rods are fixedly connected with the corresponding main arch bodies. The tied-arch floating bridge is simple in structure and convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a tie-arch floating bridge and a method for erecting the tie-arch floating bridge. Background technique [0002] The existing pontoon bridge equipment and equipment in China have a single bridge structure. From the perspective of architectural aesthetics, the ornamental value is relatively poor. After adding the tie rod arch element, the ornamental value of the pontoon bridge is greatly increased, making tourist attractions or tourist resorts attractive to tourists. The ability can be greatly enhanced, and it is of great significance to promote the development of the service industry. [0003] At the same time, the self-weight of the existing domestic pontoon bridge equipment that can be quickly erected and withdrawn, and disassembled is relatively large (1100kg per longitudinal meter), and other bridge equipment with fixed bridge feet has a greater self-weight (1200kg ...
