LARGE-SPAN SPACE SPECIAL-SHAPED ARCH RIB FLYING-SWALLOW TYPE BASKET STEEL BOX ARCH BRIDGE AND RAPID CONSTRUCTION METHOD

Document Type and Number:

WIPO Patent Application WO/2023/184679

Kind Code:

A1

Abstract:

A large-span space special-shaped arch rib flying-swallow type basket steel box arch bridge and a rapid construction method. The flying-swallow type basket steel box arch bridge comprises a main pier structure, the main pier structure is connected to an arch rib structure (4), and the arch rib structure (4) is provided with a bridge body structure (3); a sling structure (5) is arranged between the arch rib structure (4) and the bridge body structure (3). The flying-swallow type basket steel box arch bridge is simpler in structure, and most of the main bodies thereof are spliced. Moreover, during actual construction, the processes which do not interfere with each other can be carried out at the same time, so that the construction efficiency is greatly improved. In addition, two construction lines are adopted at the same time during actual construction. Not only the overlapping of processes is avoided, but also the construction efficiency is improved, and the construction time is shortened.
