PROBLEM TO BE SOLVED: To provide a safe and efficient bridge pier removal method.SOLUTION: A bridge pier removal method for cutting blocks with a wire saw comprises: a process for boring vertical holes 4 and 5 into the bridge pier; a process for horizontally cutting a pillar section 3 such as to traverse the vertical hole 4; a process for inserting a Gewindestabs steel bar into the vertical hole 4 to temporarily hold the horizontally cut pillar section 3; a process for horizontally cutting a footing portion 2 such as to traverse the vertical hole 5; and a process for inserting the Gewindestabs steel bar into the vertical hole 5 to temporarily hold the horizontally cut footing portion 2.SELECTED DRAWING: Figure 3
【課題】安全で効率的な橋脚撤去工法の提供。【解決手段】ワイヤーソーでブロック状に切断して橋脚を撤去する工法であって、前記橋脚に縦孔４、５を削孔する工程と、縦孔４を横断するように柱部３を水平切断する工程と、縦孔４にゲビンデ鋼棒を挿入して水平切断された柱部３を仮固定する工程と、縦孔５を横断するようにフーチング部２を水平切断する工程と、縦孔３に前記ゲビンデ鋼棒を挿入して水平切断されたフーチング部２を仮固定する工程による。【選択図】図３
