Besides, a second and a third removing devices in different shapes may be manufactured. Then, the frame body 14 is inserted into ground so that the upper end of a guide plate G may be positioned in the hook 28 at the lower end of the removing device 10a, and the frame body 14 is driven in up to the position of the marker 38 by a hammer. Besides, the frame body 14 is inclined in the direction opposite to that of the hooks 28, and the hooks 28 are engaged with the stopper Sp of a stabilizing plate S, and the frame body 14 is lifted upward by the lifting device of three legs and at the same time, the stabilizing plate S is pulled out and after that, the guide plate G and a resistance plate R are pulled out, and a guy anchor A is pulled out.
