| description | The invention relates to a continuous steel box girder swivel structure and a construction method, the continuous steel box girder swivel structure comprises a steel box girder, the two ends of the top of the steel box girder are fixedly provided with pulling plates, the steel box girder is fixedly provided with a base, and the base is movably connected with a hinged support through a pin shaft; one end of the tower is fixed to the hinged support, an upper anchor beam is fixed to the end, away from the hinged support, of the tower, and a sling is anchored to the upper anchor beam and the pulling plate. The hinged support at the bottom of the tower structure is connected with the main body steel box girder base through the pin shaft, so that the problem that the bottom bending moment is too large in the tensioning or rotating process of the tower is solved, detail adjustment of the tower structure is facilitated, and the construction efficiency is improved.
