RECONSTRUCTION METHOD FOR BRIDGE
To provide a reconstruction method for bridge being more efficient than a conventional method.SOLUTION: A reconstruction method for bridge comprises: a lifting process for lifting a removal object existing girder 102 which spans a bridge; a replacement girder connecting process for connecting a newly constructed replacement girder 70 to the rear end of the existing girder 102 such as to form a row; an end extending girder connecting process for connecting an end extending girder 50 to the end of the existing girder 102 such as to form a row; a sending-out process for sending out in the bridge axis direction the existing girder 102, the replacement girder 70, and the end extending girder 50 connected in the replacement girder connecting process and the end extending girder connecting process such that the replacement girder 70 is sent out to span where the existing girder 102 was installed; a dismantling process for dismantling part of the existing girder 102 sent out on the bridge 202 adjacently spanning where the existing girder 102 was installed; and an erection process for lowering the replacement girder 70 that has reached the span where the existing girder 102 was installed and erecting the replacement girder 70 to span where the existing girder 102 was installed.SELECTED DRAWING: Figure 6
【課題】従来よりもさらに効率的な橋梁の架け替え工法を提供する。【解決手段】橋梁の径間を架け渡す撤去対象の既設桁１０２を持ち上げる持ち上げ工程と、既設桁１０２の後端に新設の更新桁７０を一列状になるように連結する更新桁連結工程と、既設桁１０２の先端に先端延長桁５０を一列状になるように連結する先端延長桁連結工程と、既設桁１０２が配置されていた径間に更新桁７０が送り出されるように、更新桁連結工程および先端延長桁連結工程で連結した既設桁１０２、更新桁７０および先端延長桁５０を、橋軸方向に送り出す送り出し工程と、既設桁１０２が配置されていた径間と隣接する径間の橋梁２０２上に送り出された既設桁１０２の部位を、解体する解体工程と、既設桁１０２が配置されていた径間に到達した更新桁７０を下降させて、既設桁１０２が配置されていた径間に更新桁７０を架設する架設工程と、を備える。【選択図】図６
