To provide a bridge pier removal method that can shorten the construction period.SOLUTION: A bridge pier removal method includes: a step (S1) of installing a hanger net on one side of a bridge pier for suspending a crane; a step (S2) of forming a notch in the bridge pier with a breaker mounted on heavy equipment; a step (S3) of grabbing the top of the bridge pier with the heavy equipment and pulling it down on to an impact absorbing mound; a step (S4) of excavating around the bridge pier with the heavy equipment to expose an underground foundation; a step (S5) of crushing and removing the exposed foundation; a step (S6) of throwing backfill soil into a dug out hole; and a step (S7) of padding down the backfill soil with the heavy equipment.SELECTED DRAWING: Figure 14
【課題】工期の短縮が図れる橋脚撤去工法を提供する。【解決手段】橋脚の一側にクレーン吊り下ろしのハンガーネットを設置する段階（Ｓ１）と、重機に装着したブレーカで、橋脚に切り欠きを形成する段階（Ｓ２）と、重機で橋脚の頂部を掴み、衝撃吸収マウンドの上に引き倒す段階（Ｓ３）と、重機で橋脚の周囲を掘り下げ、地中の基礎部分を露出させる段階（Ｓ４）と、露出した基礎部分を破砕し撤去する段階（Ｓ５）と、掘り下げ穴に埋め戻し土を投入する段階（Ｓ６）と、埋め戻し土を重機で踏み固める段階（Ｓ７）と、が備えられる。【選択図】図１４
