PILE HOISTING DEVICE, AND PILE HOISTING METHOD
PROBLEM TO BE SOLVED: To provide a pile hoisting device and a pile hoisting method that prevent cracking caused by bending moment, when hoisting a pile.SOLUTION: A pile hoisting device 1 includes a body 10 having prescribed bending rigidity and holding a pile P by coming into contact with an outer peripheral surface of the pile P, and a regulating part 13 regulating a position of a lower edge P2 of the pile P. The body 10 includes a wheel 14 on a side with the lower edge P2 of the pile P, a guide part for guiding a direction of movement of the wheel 14, and a towing device for towing the body 10 on the side with the lower edge P2 of the pile P. A position of the regulating part 13 is movable in a lengthwise direction of the body 10. The pile P is mounted on the body 10, the body 10 is lifted on a side with a pile head P1 of the pile P, and the body 10 is separated from the pile P while hoisting the head part P1 of the pile P.SELECTED DRAWING: Figure 1
【課題】杭を吊り起こすときの曲げモーメントによるひび割れを防止することができる吊り起し装置及び方法を提供する。【解決手段】吊り起こし装置１は、所定の曲げ剛性を有し、杭Ｐの外周面に接触して杭Ｐを保持する本体１０と、杭Ｐの下端Ｐ２の位置を規制する規制部１３とを備える。本体１０の杭Ｐの下端Ｐ２側に車輪１４を備える。車輪１４の移動方向を案内する案内部を備える。本体１０の杭Ｐの下端Ｐ２側を牽引する牽引装置を備える。本体１０の長手方向における規制部１３の位置が可変である。本体１０に杭Ｐを載せ、本体１０の杭Ｐの頭部Ｐ１側を吊り起こし、杭Ｐの頭部Ｐ１を吊り上げた状態で杭Ｐから本体１０を分離する。【選択図】図１
