PILE EXTRACTOR AND PILE EXTRACTION METHOD
To provide a pile extractor and a pile extraction method that can efficiently pull out an existing pile in a narrow space.SOLUTION: A pile extractor 100 for pulling out an existing pile buried in the ground comprises: a portal frame 1 an upper frame body of which is supported by a column; an upper first sheave 7 that includes multiple pulleys provided to the upper frame body 6; an upper second sheave 8 that includes multiple pulleys provided to the upper frame body; a lower first sheave 2 that includes multiple pulleys and has a wire laid between itself and the upper first sheave; and a lower second sheave 3 that includes multiple pulleys and has a wire laid between itself and the upper second sheave. The lower first sheave 2 and the lower second sheave 3 can be independently lifted by suspending different existing piles.SELECTED DRAWING: Figure 1
【課題】狭いスペースで既設杭を手際よく引抜く杭抜き機、及び杭抜き工法を提供する。【解決手段】地中に埋設された既設杭を引抜く杭抜き機１００であって、支柱によって上枠体が支持される門型フレーム１と、前記上枠体６に設けられた多滑車からなる上第１シーブ７と、前記上枠体に設けられた多滑車からなる上第２シーブ８と、前記上第１シーブとの間でワイヤーが掛け渡され、多滑車からなる下第１シーブ２と、前記上第２シーブとの間でワイヤーが掛け渡され、多滑車からなる下第２シーブ３と、を備え、前記下第１シーブ２、及び前記下第２シーブ３はそれぞれ別の既設杭を吊下げて独自に昇降可能であることを特徴とする杭抜き機とした。【選択図】図１
