SENDING-OFF METHOD OF BRIDGE

PROBLEM TO BE SOLVED: To provide a sending-off method of a bridge, reducing the size of a facility on a destination side. SOLUTION: In this sending-off method of a bridge 1 for sending-off a bridge 5 from one of an abutment and a pier 4 to the other to install the bridge 5 between the abutments 2 or the piers 4, the deflection of the bridge 5 when supportedly cantilevered to send out the bridge 5 is obtained beforehand, and the inclination angle of the bridge 5 is obtained based on the deflection of the bridge 5 thus obtained, the shape of the bridge 5, and the height of the abutment 2 or the pier 4 on the sending side so that the height of the end of the supportedly cantilevered bridge 5 substantially matches the height of the abutment 2 or pier 4 on the destination side. When the bridge 5 is sent-off, the bridge 5 is tilted to the inclination angle thus obtained. The tilted bridge 5 is moved from the abutment 2 or the pier 4 on the sending side toward the abutment 2 or the pier 4 on the destination side. The end of the moved bridge 5 is supported by the abutment 3 or the pier 4 on the destination side. COPYRIGHT: (C)2009,JPO&INPIT
