Problems solved by technology

[0003] At present, there are certain deficiencies in the construction of long-span steel box double-arch bridges. During the construction of steel box girders, the large sections of steel box girders are not easy to transport and assemble, which makes the construction of long-span steel box double-arch bridges difficult. Higher, and the construction period is long, the economic benefit is low, and the project risk is relatively high, which is not conducive to the needs of construction

Abstract

The invention discloses a construction method of a large-span steel box continuous arch bridge. The construction method comprises seven steps of dividing large sections of steel box girders, arranging shortcuts and gantry cranes, arranging a steel trestle, erecting a bracket, assembling the steel box girders, mounting other hole span steel girders and dismounting the bracket. According to the steel box girder, large-section splicing, flat car transportation and gantry crane hoisting are completed in a splicing field, the welding work amount of field installation is reduced, the project quality is guaranteed, before installation construction, through the BIM virtual installation technology, the problems occurring in the installation process of the large sections of the steel bridge are found out, an optimal correction scheme is given, and the construction efficiency is improved. Field work is reduced, and construction quality is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a large-span steel box continuous arch bridge. Background technique [0002] With the rapid development of my country's economy, the requirements for transportation are increasing day by day, and steel structure bridges play an irreplaceable role as an important infrastructure. Especially the long-span steel box double-arch bridge is favored by people for its unique structure and beautiful shape, and is widely used in the construction of highway transportation infrastructure. [0003] At present, there are certain deficiencies in the construction of long-span steel box double-arch bridges. During the construction process of steel box girders, the large sections of the steel box girders are inconvenient to transport and inconvenient to assemble, which leads to the construction difficulty of long-span steel box double-arch bridges. It is rela...
