AI Technical Summary
Existing construction techniques for erecting continuous steel box girders on curved sections have limitations, including the need for a wide construction site and large working space, as well as insufficient space on top of the girder when the bridge erecting machine is working on curved sections. These issues increase construction difficulties and risks.
The bridge erecting machine's front outrigger transverse track beam is erected using support columns, and a steel box girder passage height is reserved below the front outrigger track beam. Rigid pads on the top of the beam are used to replace some of the support columns, and the support structure is adjusted to meet the support force requirements of the middle outrigger of the bridge erecting machine. The steel box girder is erected one span at a time.
It improved the utilization efficiency of the space on the top of the bridge girder, resolved the conflict between the bridge erecting machine and the track, reduced construction risks, and enhanced the versatility and construction safety of the bridge erecting machine.
