GIRDER REPLACEMENT METHOD
To provide a girder replacement method with which construction period can be shortened, cost can be reduced and working space can be reduced.SOLUTION: A girder replacement method according to an embodiment is a girder replacement method of a cross-river bridge 1 that includes multiple existing bridge abutments 2 lined up along the width direction of a river R and an existing girder 3 across the existing abutments 2. The girder replacement method includes a step of installing a construction girder 10 on the areas of ground G on both sides of a first direction D1 when viewed from the river R, a step of constructing new abutments 20 at the bottom of each construction girder 10, a step of installing a new girder 30 above the existing abutments 2 and the new abutments 20, a step of removing the construction girder 10 installed on the ground G and installing a sleeper support girder 40 on the newly installed girder 30 above the ground G and a step of removing the existing girder 3 and installing the sleeper support girder 40 on the new girder 30 above the river R.SELECTED DRAWING: Figure 8
【課題】工期を短縮し、コストを低減できると共に作業スペースを低減させることができる桁架け替え方法を提供する。【解決手段】一実施形態に係る桁架け替え方法は、河川Ｒの幅方向に沿って並ぶ複数の既設橋台２と、複数の既設橋台２を架け渡す既設桁３とを備えた河川横断橋１の桁架け替え方法である。桁架け替え方法は、河川Ｒから見て第１方向Ｄ１の両側に位置する地盤Ｇのそれぞれに工事桁１０を設置する工程と、各工事桁１０の下部に新設橋台２０を構築する工程と、複数の既設橋台２、及び複数の新設橋台２０の上方に新設桁３０を設置する工程と、地盤Ｇに設置した工事桁１０を撤去すると共に、地盤Ｇの上方に位置する新設桁３０に枕木受桁４０を設置する工程と、既設桁３を撤去すると共に、河川Ｒの上方に位置する新設桁３０に枕木受桁４０を設置する工程と、を備える。【選択図】図８
