DRIVE-OUT ERECTION METHOD OF BRIDGE

PROBLEM TO BE SOLVED: To provide a drive-out erection method of a bridge capable of erecting the bridge in a short period in the state where the influence to the environment or a circumferential area is reduced by dispensing with secured working site of wide range and efficiently driving out the bridge without limiting the shape of the bridge to a linear one. SOLUTION: This drive-out erection method of bridge comprises steps of manufacturing the bridge 1 on a working frame 20, connecting a temporary girder made on a traveling truck 10A (vehicle) to the bridge 1 and then supporting the bridge 1 by the traveling truck 10A; moving the traveling truck 10A to protrude the bridge 1 from the working frame 20; extending the bridge 1; supporting the bridge 1 by the traveling truck 10A in the rear of the bridge 1 after temporarily placing the bridge 1 on a pier 2; moving the traveling truck 10A to drive out the bridge 1; and repeating the extension and driving-out of the bridge 1, thereby erecting the bridge 1.
