Cutting machine and cutting method using a dry wire saws for dismantling nuclear power plant construction

摘要

The present invention relates to a cutting system using a dry wire saw for dismantling a nuclear power plant structure, capable of cutting and dismantling a reactor shielding wall and a dome structure and reducing a construction period, and a cutting and dismantling method thereof. The cutting system using a dry wire saw for dismantling a nuclear power plant structure according to an embodiment of the present invention includes a diamond wire saw (100) which cuts a nuclear power plant structure (W) by driving a wire rope (110), a driving device (200) which drives the diamond wire saw (100), a collection cover (300), a collection device (400), a dust collecting device (800), and a wire rope fixing device (900) which is installed in a preset position of the wire rope (110) and is composed of an upper pulley (910), a lower pulley (920), a support unit (930), and a jack (940).
