REMOVING METHOD, AND REMOVING JIG
To provide a removing method of hardened material inside a pile head that can be carried out even by a small lifting machine.SOLUTION: In a state where a removing jig 1 used for removing soil cement 301 in which cement milk is hardened is inserted in advance along an inner peripheral surface of a pile head of a hollow pile 2, the hollow pile 2 is inserted into the cement milk, and the soil cement 301 inside the pile head is then removed. The removing jig 1 comprises a plurality of cylindrical portions 11, 12 that divide an inside of the pile head into a plurality of sections in plan view, and the soil cement 301 in each section divided by the plurality of cylindrical portions 11, 12 is pulled out individually.SELECTED DRAWING: Figure 5
【課題】小さな揚重機でも対応可能な杭頭部内の硬化物の除去方法等を提供する。【解決手段】セメントミルクが硬化したソイルセメント３０１の除去に用いる除去治具１を、中空杭２の杭頭部の内周面に沿って予め挿入した状態で、中空杭２をセメントミルク中に挿入し、その後、杭頭部内のソイルセメント３０１を除去する。除去治具１は、杭頭部内を平面視で複数の区画に分割する複数の筒状部１１、１２を備え、複数の筒状部１１、１２によって分割された各区画のソイルセメント３０１が、個々に抜き取られる。【選択図】図５
