Abstract

PURPOSE: To carry out disassembling work safely and economically by attaching a funnel-shaped cutting edge body to the opening end portion of a cylindrical concrete structure such as flue, silo or the like, and pulling it down through a tensile material. CONSTITUTION: A cutting edge body 12 capable of enlarging formed to a funnel shape, is attached to the opening end portion of a cylindrical concrete structure 10. Next, this is attached to a turnable anchoring portion 20 fixed to a lower inner surface of a concrete structure 10. Next, a diameter-widening jack 16 is extended, a tensile jack 26 provided at the anchoring portion 22 is driven while exerting cutting edge bit 12a of the cutting edge body 12 in a widening direction, and cutting edge body 12 is pulled downward through a tensile member 18. Then, the cutting edge body 12 is gradually lowered and the concrete structure 10 is gradually crushed starting from the end portion of the opening. In succession, a ring-shaped frame body 22 at the anchoring portion 20 is turned downward and the crushing work is continued sequentially.
