Abstract
The invention relates to a construction method of a large-span large-section steel box girder, which is characterized in that temporary piles are combined with square columns to form an effective temporary support structure, so that the stability of the steel box girder in the construction process is ensured, and the potential safety hazard of construction is reduced; the lifting system is provided with a lifting rod, so that the efficient hoisting and positioning of the steel box girder can be realized, the spliced steel box girder can be smoothly lifted under the large-span condition through the design, and the smooth construction is ensured; the existing bridge plate is adopted as a construction platform, and the temporary support and the fixed base are combined, so that the construction steps are simplified, and the construction efficiency is improved; by ensuring the reliable connection between the No.0 steel box girder and the assembled steel box girder, the stability and the bearing capacity of the whole structure are optimized, so that the engineering quality of the whole bridge is improved, and the service life of the whole bridge is prolonged.
