TOOL FOR PILE EXTRACTION AND PILE EXTRACTING METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a pile extracting technique that is relatively simple and generally useable.SOLUTION: The purpose of this invention is achieved by a pile extracting tool which is prepared separately from a drilling casing. The pile extracting tool 1 has a cavity member 4 provided between the drilling casing 2 and a pile 3, and multiple chucking members 5 provided in a state extruding into the inside of the cavity member 4. The pile extracting tool 1 is structured such that it can hold the pile 3 by way of the chucking members 5 encroaching upon the pile 3.SELECTED DRAWING: Figure 1
【課題】比較的簡易で，かつ，汎用性の高い，埋設杭の引き抜き技術を提供する。【解決手段】本発明の目的は，削孔ケーシングとは別に用意された杭抜用器具によって達成される。杭抜用器具１は，削孔ケーシング２と埋設杭３との間に設置される空洞部材４と，空洞部材４の内部に突出した状態で設置される複数のチャッキング部材５と，を備えている。そして，杭抜用器具１は，チャッキング部材５が埋設杭３に食い込むことによって当該埋設杭３を保持することができるように構成されている。【選択図】図１
