CONSTRUCTION METHOD OF BRIDGE UTILIZING STRETCHED CABLE

摘要

PROBLEM TO BE SOLVED: To provide a construction method of a bridge wherein a road for construction is not needed for transporting materials and mechanical equipment up to an intermediate pier, cost and construction period can be reduced, the design cross area force of a girder member during bridge construction is not made greater than that after bridge completion, and earthquake resistance of the bridge during construction can be improved. ;SOLUTION: The construction method of a bridge is composed of a process for stretching a cable 13 between abutments 11b, a process for fixing the cable 13 on piers 15a, 15b previously vertically provided between the abutments, and a process for successively transporting a plurality of precast members 20 as the cable 13 is made a track and continuously providing them between the abutment and the pier and between the piers. A member formed to previously precast a web member vertically provided from a lower floor board and an upper floor board as the precast member 20 may be employed, and after the precast member is continuously provided between the abutment and the pier, a process forming the upper floor board may be included on the web member.;COPYRIGHT: (C)1998,JPO
