GIRDER REPLACEMENT METHOD AND BRIDGE PIER REMOVAL METHOD
To provide a girder replacement method and a bridge pier removal method capable of improving the workability of replacement work and improving earthquake resistance.SOLUTION: A girder replacement method according to an embodiment of the present invention is a girder replacement method for an existing river crossing bridge including the steps of: installing a new main girder base 10 for raising a foundation on an existing bridge pier 2; erecting a new girder 13 on the new main girder base 10; installing a new sleeper bearing girder 11 on the new girder 13; and removing an existing girder 3 attached to the existing bridge pier 2.SELECTED DRAWING: Figure 10
【課題】架け替えの作業の作業性を向上させることができると共に、耐震性を向上させることができる桁架け替え方法及び橋脚撤去方法を提供する。【解決手段】一実施形態に係る桁架け替え方法は、既設の河川横断橋の桁架け替え方法であって、既設の橋脚２の上に基礎の嵩上げを行う新設主桁台座１０を設置する工程と、新設主桁台座１０の上に新設桁１３を架設する工程と、新設桁１３に新設の枕木受桁１１を設置する工程と、既設の橋脚２に取り付けられていた既設桁３を撤去する工程と、を備える。【選択図】図１０
