PILE EXTRACTION DEVICE AND PILE EXTRACTION METHOD
To provide a pile extraction device and a pile extraction method to allow pile extracting operation for an installed pile to be easily performed.SOLUTION: A pile extraction device is provided with: a cylindrical casing 11 with an inner side through which an installed pile P is inserted; a lifting wire 12 wound around an outer peripheral surface of the installed pile P to lift the installed pile P; and a slide mechanism 13 sliding the lifting wire 12, which has been temporarily fixed on a lower end of the casing 11, in an axial direction from the lower end to the installed pile P side.SELECTED DRAWING: Figure 1
【課題】既設杭の引き抜き作業をスムーズに行うことが可能な杭抜き装置および杭抜き方法を提供する。【解決手段】内側に既設杭Ｐが通される筒状のケーシング１１と、既設杭Ｐの外周面に巻き付けられて、この既設杭Ｐを引き上げる引上げワイヤ１２と、ケーシング１１の下端部に仮止めされた引上げワイヤ１２を、前記下端部から既設杭Ｐ側に軸方向にスライドさせるスライド機構１３と、を備えた杭抜き装置を構成する。【選択図】図１
