Abstract
PURPOSE: To enable disassembly work to be implemented safely and economically by making a plumb bob pendent from a rod loosely drop on the central axis of a funnel-shaped cutting edge body put on an opening of a cylindrical concrete structure opened by its upper end. CONSTITUTION: A funnel-shaped cutting edge body 12 having a larger outer diameter than the maximum diameter of a structure 10 is placed on an opening end of the hollow cylindrical concrete structure 10. Next, a plumb bob being fitted loosely in a rod 18 is pendent from a central axis of the cutting edge body 12 by being wound up by a winch 28 via sheaves 24, 26. In addition, by the use of a diameter expanding jack 16, the cutting edge body 12 is opened in diameter, an then the winch 28 is released in order to permit the plumb bob 22 to fall down and thereby the structure 10 is broken at once.
