Abstract
A wire sawing method for cutting buildings, dams, bridge piers, foundations and other reinforced concrete structures is exhibited. This method is characterized by laying a cable on a reinforced concrete structure and using a moving type cable driving machine which pulls the cable for cutting and drives it circularly while the machine itself moves, together in series with a fixed type cable driving machine which drives the tension side part of the cable for cutting. The endless cable for cutting is circularly driven while its running speed and tension are adjusted by the cable driving system.
Claims4
A wire sawing method for cutting reinforced concrete structures comprising:
- reeving an endless cutting cable around the concrete structure to be cut and through the pulleys of a cable driving system, said cable driving system including a movable cable driving machine and a fixed cable driving machine arranged in series to circularly drive said endless cable;
- pulling said cable with said movable cable driving machine;
- driving the tension side of said cable with said fixed cable driving machine, said movable cable driving machine and said fixed cable driving machine cooperating so as to adjust the speed and tension of said endless cable.
