REMOVING DEVICE AND REMOVING METHOD FOR REMOVING EXISTING ANCHOR FROM GROUND
PROBLEM TO BE SOLVED: To provide a removing device and removing method in which long buried object, such as an existing anchor, is cut into a desired length and the buried object is removed from ground with a simple structure.SOLUTION: A removing device 10 comprises: an inner tube 11, an outer tube 12, a cutting arm 13, a projecting part 14, a swivel 15 and a lock mechanism 16. The inner tube 11 digs a periphery of an existing anchor. The outer tube 12 is equipped on an outside of the inner tube 11 and digs a periphery of the inner tube 11. An end part of the cutting arm 13 is engaged on a near part of a tip end part of the inner tube 11 in a pivotable manner and comprises a blade cutting the anchor at a tip end part extending to a rear side in a rotating direction of the inner tube 11. The projecting part 14 is arranged on the outer tube 12 at a corresponding position to the cutting arm 13 and pushes the cutting arm 13 toward the central axis of the anchor by rotation of the outer tube 12 in the rotating direction prior to the inner tube 11.SELECTED DRAWING: Figure 1
【課題】既設アンカーのような長尺の埋設物を所望の長さに切断しかつ埋設物を地中から取り除く簡単な構造の撤去装置及び撤去工法を提供する。【解決手段】撤去装置１０は、内管１１と外管１２と切断アーム１３と凸部１４とスイベル１５とロック機構１６とを備える。内管１１は、既設のアンカーの外周を掘削する。外管１２は、内管１１の外側に装着され内管１１の外周を掘削する。切断アーム１３は、内管１１の先端部近傍に基端部が枢着され、内管１１の回転方向に後方側へ延びた先端部にアンカーを切断する刃を有している。凸部１４は、切断アーム１３に対応する位置の外管１２に設けられ、回転方向に内管１１よりも先行して外管１２が回動することで切断アーム１３をアンカーの中心軸に向かって押し出す。【選択図】図１
