Abstract

The application discloses an installation method and installation structure of a steel arch bridge arch rib section. The installation method comprises the steps that a guide assembly is arranged at acantilever end of an installed arch rib section; and when an arch rib section to be installed is installed, the installed arch rib section and the arch rib section to be installed are aligned throughthe guide assembly. The technical problems that due to the fact that accurate alignment of the arch rib sections is difficult, the adjusting period is long, and the installation efficiency is low aresolved.

Description

technical field [0001] The present application relates to the field of bridge engineering construction, in particular, to an installation method and installation structure of an arch rib segment of a steel arch bridge. Background technique [0002] Steel structure bridges are more and more popular because of their light weight, beautiful shape, energy saving and environmental protection, and uniform force. In order to ensure the processing quality of steel box girders, most steel box girder bridges adopt the structural form of on-site processing and on-site installation. The arch rib is the key part of the construction of the arch bridge. Generally, it is welded section by section from bottom to top on site. The construction, precision and alignment control are very strict. [0003] The steel structure installation site generally adopts the bracket method construction technology. The conventional bracket method sets a vertical jack on the top of the bracket to adjust the el...
