PURPOSE:To enable the smooth travelling of a cutting cable by stretching the cable for cutting, in which cutting capacity is imparted to a wire rope, on a reinforced concrete structure while circulating the cable and making the cable travel by a cable driving gear. CONSTITUTION:Cables 18 for cutting guided by a pair of guide pulleys 7a, 7b are installed onto the same plane as the cutting predetermined surface of the surface of a reinforced concrete structure 2 along the surface of the reinforced concrete structure 2. A cable driving gear 15 is operated for circulating the cutting cable 18 and making the cutting cable 18 travel under an endless state under the adjustment of tension and travelling speed through an auxiliary guide pulley 8c mutually separating the cable 18 for cutting. When a cable driving pulley 16 is rotated and driven while the cable driving gear 15 is energized movably along a rail 11, the cable 18 for cutting is circulated and made to travel under required tension. The reinforced concrete structure 2 rubbed and contacted with the cable 18 for cutting is cut gradually from the surface of the structure 2 to the inside of the structure 2. Accordingly, damage due to the mutual contact of the cable 18 for cutting can be prevented. |
