ENVIRONMENTALLY-FRIENDLY CUTTING APPARATUS USING A WIRE SAW, AND CUTTING METHOD USING SAME

摘要

The present invention relates to an apparatus and to a method for cutting a concrete structure using a diamond wire saw. More particularly, the present invention relates to an environmentally-friendly cutting apparatus using a wire saw and to a cutting method using the same, capable of completely collecting concrete sludge and dust generated during the cutting of the concrete structure without deteriorating work efficiency, and specially controlling the sludge generated during underwater cutting in an efficient manner to prevent environmental contamination. The cutting apparatus of the present invention comprises a jig case and a sealing cover unit for sealing the cut surface of a target structure for cutting, a wire saw, and a jig for changing the direction (a set of pulleys for guiding the wire saw), thus perfectly preventing dust and sludge generated during cutting of the structure from being exposed to the air or water to prevent environmental contamination. Further, the present invention is advantageous as it prevents the wire saw and the jig for changing direction from being outwardly exposed, which may otherwise cause injury to workers during cutting, thus improving the safety of cutting work. Further, the present invention collects sludge generated during the cutting of the structure, enables the collected sludge to settle in a settling tank, and enables purified upper water to be supplied to the sealing cover unit from a water purifying channel and be reused as a coolant for cooling the frictional heat on the cut surface, thus preventing environmental contamination and saving resources.
