Special-shaped (Three-curved) Steel Box Girder Assembly and Installation Construction Method

This construction method mainly summarizes the construction technology of processing and manufacturing hyperbolic steel box girder with curved edges in section. It combines the traditional methods of steel box girder structure factory processing and on-site installation. At the same time, the quality management of the construction process was clarified, the traditional construction process was changed, and the steel structure project was modeled and dismantled by tekla, and bold innovations were used to ensure the quality and safety of the project, and greatly shorten the construction period. Reduced engineering costs.
