Three-truss continuous steel truss girder-pushing device and arrangement method thereof

摘要

The present invention claims a three-truss continuous steel truss girder-pushing device and an arrangement method thereof. The device comprises three supporting structures of left, center and right, the three supporting structures are provided respectively with left and right side truss slideway girders and a middle truss slideway girder. The front ends of the slideway girder are provided with an operating platform where horizontal continuous pushing jacks are installed; the front ends of the left and right slideway girder and the center slideway girder are each provided with four vertical lifting jacks. The three-truss continuous steel truss girder-pushing device simultaneously pushes the two side trusses of the steel truss beam only, while the center truss slides passively, thereby improving construction efficiency and reducing construction costs.
