INCREMENTAL EXTRUDING CONSTRUCTION METHOD OF SUSPENSION BRIDGE AND SUSPENSION BRIDGE WITH SLIDE GIRDER THEREOF

摘要

The present invention relates to a suspension floor slab bridge and a construction method thereof. The present invention has effects of excluding handling equipment such as timbering or a crane, an over hanger device, and a position adjusting device or the like for mounting a segment on a first cable which is a supporting tendon, minimizing surrounding natural environment damage and a working space required by a start-side abutment, minimizing an external power device for moving a precast deck to a reach-side, increasing construction stability by simply and easily performing supporting tendon and segment mounting in a predetermined place, effectively performing movement construction and minimizing arrangement of a roller device for moving a segment according to a supporting tendon, quickly and easily performing connection between segments to be assembled in a field, effectively performing mounting moving connecting construction of a segment even on a narrow abutment, and excluding pairing installation to be attached for minimizing the effect by wind load due to the shape of the end part of a segment.
