PILE EXTRACTOR AND PILE EXTRACTION METHOD
PROBLEM TO BE SOLVED: To provide a pile extractor capable of extracting a pile without hindrance even at a work place with a restriction on a height, an available space, etc.SOLUTION: A pile extractor 1 is for extracting a pile buried in a ground, and includes a first chuck 1a and a second chuck 1b suspended from pressure bearing means above ground. The first chuck 1a and the second chuck 1b are respectively provided with chuck means 1d for gripping the pile by pressing a chuck member against a peripheral wall surface of the pile. The first chuck 1a is suspended through a lifting cylinder, while the second chuck 1b is suspended by the pressure bearing means (4, 4a) through a connecting rod, at a position below the first chuck 1a.SELECTED DRAWING: Figure 1
【課題】本発明は、杭用引抜き装置に関し、例えば、高さ制限や狭小スペース等の制限のある作業場所であっても、支障なく杭の引抜きができるようにすることが課題である。【解決手段】地盤に埋設された杭を引き抜く装置において、地上側の支圧手段に吊持される第一チャック１ａと第二チャック１ｂとが設けられ、前記第一チャック１ａと第二チャック１ｂとには、杭の周壁面にチャック部材を押しつけて杭を掴持するチャック手段１ｄがそれぞれ設けられ、前記第一チャック１ａが昇降用シリンダーを介して吊持され、前記第二チャック１ｂが前記第一チャック１ａの下位置で前記支圧手段（４，４ａ）に連結棒を介して吊持されてなる杭用引抜き装置１とする。【選択図】図１
