PULLING-OUT METHOD OF EXISTING PILE
To provide an unconventional and very practical pulling-out method of an existing pile.SOLUTION: A pulling-out method of an existing pile 60 is to repeat a lifting/cutting process such as lifting the existing pile 60 buried in a ground 50 and cutting an upper end part of the existing pile 60, comprising inserting and arranging, in an excavation hole 51 formed in the ground 50 surrounding the existing pile 60, a long connection member 1 for pulling-up provided with a connection part 1a for connection with the existing pile 60, and in the lifting/cutting process, backfilling material 40 is filled through the excavation hole 51 into a pulling-up space part 52 created between a lower end part of the existing pile 60 and the ground 50 by pulling-up the long connection member 1 for pulling-up connected on the existing pile 60.SELECTED DRAWING: Figure 1
【課題】本発明は、従来にない非常に実用的な既設杭の引き抜き方法を提供することを目的とする。【解決手段】地盤50に埋設された既設杭60を上昇させ、前記既設杭60の上端部位を切断する上昇切断工程を繰り返し行うことで該既設杭60を引き抜く既設杭の引き抜き方法であって、前記既設杭60の周囲の地盤50に形成した掘削孔51に、前記既設杭60に連結する連結部1aを設けた引き上げ長尺連結部材1を挿入配設し、前記上昇切断工程において、前記既設杭60に連結した前記引き上げ長尺連結部材1を引き上げることで該既設杭60の下端部と地盤50との間に形成される引き抜き空間部52に、前記掘削孔51を介して埋戻材40を充填する既設杭の引き抜き方法である。【選択図】図1
