METHOD FOR REPLACING BRIDGE BEARING
To provide a method for replacing a bridge bearing capable of reducing the number of newly installed bearings.SOLUTION: A method for replacing bridge bearing for replacing bearings of a bridge 1 having a plurality of main girders 3, includes performing the following steps: a main girder temporary receiving step of installing main girder provisional means K for temporarily supporting the load of the plurality of main girders 3; an existing bearing removal step of removing an existing bearing 4; a cutting-down step of hacking and cutting-down an upper part of a substructure (abutment 2) of the bridge 1; a new bearing installation step of installing a new bearing 8 in a space opened up by cutting-down in the cutting-down step; and a transverse beam construction step of constructing a transverse beam 9 with the direction intersecting the bridge axis direction as the longer direction in the space opened up by cutting-down in the cutting-down step.SELECTED DRAWING: Figure 5
【課題】新たに設置する新設支承の数を低減することのできる橋梁の支承取替工法を提供する。【解決手段】複数の主桁３を有する橋梁１の支承を取り替える橋梁の支承取替工法において、複数の主桁３の荷重を一時的に支える主桁仮受手段Ｋを設置する主桁仮受工程と、既設支承４を撤去する既設支承撤去工程と、橋梁１の下部構造（橋台２）の上部を斫り取って切り下げる切下工程と、切下工程で切り下げたスペースに新設支承８を設置する新設支承設置工程と、切下工程で切り下げたスペースに橋軸方向と交わる方向を長手方向とする横梁９を構築する横梁構築工程と、を行う。【選択図】図５
