| description | The invention discloses a method for achieving synchronous pushing of large-span steel-concrete composite beams through a cable-stayed tower. The method comprises the steps that: the tower is mounted on a steel box beam, a hinged support is arranged at the bottom of the tower, and the tower is connected with the top of the steel box beam through the hinged support; and a pushing device is used for pushing a guide beam and the steel box beam to a middle pier and a guide beam receiving platform successively from a splicing area, and in the pushing process, under the action of the hinged support, the tower can incline by a small angle. The hinged support is arranged at the bottom of the tower so that the tower can incline, the constraint of rotation in a bridge direction can be released, and the tower and the steel box beam can rotate freely; in the pushing process, when the hogging moment of a pushing cantilever is increased or the guide beam is mounted onto the piers, the change of the horizontal force of the |
