Abstract

PURPOSE: To facilitate the removal of anchors, by a method wherein a piston of an air cylinder can always vibrate longitudinally in the axial direction at the number of vibrations coinciding with the number of natural vibrations of a nonanchoring length of an anchor body, and is effectively vibrated sympathitically.
CONSTITUTION: An axial vibration is provided to an anchor body 4, resonnance is executed by giving the number of longitudinal vibrations always coinciding with the number of natural vibrations of length of a nonanchoring with a connector 6, and an axial anchor hooking of a surface anchoring between the body 4 and the connector 6 is destroyed gradually from the base end side. During that peiod, a given tension is always given outward so that the anchor body 4 is prevented from the occurrence of a bending phenomenon.
