REPAIR METHOD OF BRIDGE PIER
To build a cross beam without removing pier studs made of reinforced concrete.SOLUTION: A cross beam 12b and the upper part of a pier stud 12a that is continuous with the cross beam 12b are removed, concrete is removed from the upper end of the remained pier stud 12aa after removal over a predetermined height to expose the reinforcing bar R, a steel cross beam unit CB, which includes a cross beam CB1 and a tubular pier stud CB2 and is the substitute for the removed cross beam 12b and the upper part of the pier stud 12a, is moved in, the exposed reinforcing bar R is placed on the remained pier stud 12aa so as to surround it with the pier stud CB2, and concrete is cast with the pier stud part CB2 being formwork to integrate the remained pier stud 12aa and the steel cross beam unit CB.SELECTED DRAWING: Figure 15
【課題】鉄筋コンクリート造の橋脚の脚柱を残して横桁を新設する。【解決手段】横桁１２ｂおよび横桁１２ｂに連続した脚柱１２ａの上部を撤去し、撤去後の残留脚柱１２ａａの上端から所定高さにわたってコンクリートを除去して鉄筋Ｒを露出させ、横桁部ＣＢ１および筒状の脚柱部ＣＢ２を備えるとともに撤去された横桁１２ｂおよび脚柱１２ａの上部の代替となる鋼製横桁ユニットＣＢを搬入し、露出した鉄筋Ｒを脚柱部ＣＢ２で包囲するようにして残留脚柱１２ａａの上に設置し、脚柱部ＣＢ２を型枠としてコンクリートを打設して残留脚柱１２ａａと鋼製横桁ユニットＣＢとを一体化する。【選択図】図１５
