EXISTING PILE EXTRACTION METHOD
To provide an existing pile extraction method capable of restoring the ground by constructing a high-quality solidified material in a place where an existing pile is pulled out.SOLUTION: An existing pile extraction method includes: an edge-cutting step of cutting the edge between an existing pile and the ground by penetrating a borehole casing into the ground while injecting drilling water along the outer periphery of the existing piles left underground; a restoration step of restoring a pile pullout remain by pulling out the existing pile and by solidifying muddy water that accumulates at the pile pullout remain to build a solidified body. Before the restoration step, the bottom solidification liquid is injected around the existing pile.SELECTED DRAWING: Figure 2
【課題】既存杭の杭引抜き跡に高品質な固化体を構築し、地盤を復元することである。【解決手段】地中に残置された既存杭の外周に沿って削孔水を噴射しながら削孔ケーシングを地中に貫入し、前記既存杭と地盤との縁を切る縁切り工程と、前記既存杭を引抜くとともに、杭引抜き跡に貯留する泥水を固化させて固化体を構築し、前記杭引抜き跡を復元する復元工程と、を備える既存杭の引抜き工法であって、前記復元工程の前に、前記既存杭の周囲に前記底部用固化液を注入する。【選択図】図２
