After doing this, while constantly pulling the motor drive device 15 to the right (in the direction of the arrow) with an appropriate force on the rail 22 by the wheels 21, 21, etc. attached to the motor drive device 15,
The wire saw 20' is rotated by the driving pulley 16 to continuously cut the reinforced concrete IJ-t 19.

なった。In this way, the steel wire 14 is twisted while running, and the cutting blades 3 of the beads 1 that come into contact with the cut surface one after another do not have a fixed surface facing the cut surface of the cut object. As a result, the beads 1 are brought into contact randomly, and the so-called uneven wear phenomenon of the beads 1 is prevented (effects of the invention) As explained above, according to the bead shape of the wire saw according to the present invention, Since the spiral cutting blades are formed at a predetermined distance from each other and are curved in the axial direction, even when cutting the ground or structures with a wire saw using the spiral cutting blades, the outer surface of the beads will be uniform. This eliminates so-called one-sided wear due to wear, and the period for replacing the beads becomes longer, eliminating the hassle of replacement work, making it possible to reduce the cost of the wire saw using this bead.
