UNDERGROUND PILE BREAKING METHOD
To provide an underground pile breaking method that reduces the occurrence of vibration, noises, and dust significantly so that it can be used in city centers or the like.SOLUTION: The underground pile breaking method includes the steps for: piercing breaking substance loading holes in an underground pile, the pile head of which is exposed, from the pile head in the longitudinal direction of the underground pile; inserting, from the pile head into the breaking substance loading holes, breaking substances and cement tampers alternately in a manner of multiple layers in the longitudinal direction of the underground pile so that the breaking substances are arranged at regular intervals and cracks caused by letting off breaking substances on the pile head side do not reach the next breaking substance loading hole on the bottom side; and breaking the pile by lighting the multiply layered, inserted breaking substances in order from the pile head to the bottom of the underground pile.SELECTED DRAWING: Figure 1
【課題】都心等における利用にも耐えられるように、振動と騒音と粉塵の発生をより低減した地中杭破砕方法を提供する。【解決手段】杭頭が露出された状態の地中杭に、地中杭の長さ方向に沿って杭頭から破砕薬装填孔を穿孔する工程と、杭頭から、破砕薬装填孔に、破砕薬とセメントタンパーとを交互に、破砕薬が杭頭側の破砕薬の破砕に起因する亀裂がその直近の底部側の破砕薬装填孔に到達しない程度の一定の間隔、となるように、地中杭の長さ方向に沿って複数段に挿入する工程と、複数段に挿入された破砕薬を、杭頭から地中杭の底部に向けて順次に、着火して破砕する工程と、を有する。【選択図】図１
