As disclosed in the patent specification No. 8, it is possible to appropriately adopt a structure in which the drive pulley is moved by rails and wheels, a structure in which it is moved by a rack and a pinion, etc.

しい。If the object to be cut is underwater, ensure the driving force of the cutting wire to overcome the water resistance as the cutting wire travels underwater18, and to effectively feed the loose side of the cutting wire to the object to be cut. In addition, it is preferable to use a fixed wire drive machine between the object to be cut and the moving wire drive machine.

はできない。When a barge floating on the water swings up and down, back and forth, or left and right due to waves caused by passing ships or strong winds in the vicinity, the position of the wire drive machine relative to the object to be cut changes rapidly. Sudden tension is repeatedly generated in the cutting wire stretched between them, especially on its tension side. Note that even if the barge is equipped with an outrigger device, the influence of rocking caused by waves as described above cannot be completely prevented.

では台船の上記揺動には対処できない。However, the sudden increase in tension of the cutting wire is quickly alleviated by the elastic displacement of the cushion pulley, thereby preventing the cutting wire from breaking. In order to obtain a tension-relieving effect with excellent responsiveness, it is preferable to install the cushion pulley on the barge at a position closer to the object to be cut than the guide pulley. The cushion pulley may normally be provided on the tension side of the cutting wire where the tension is likely to increase due to the rocking of the barge, but it can also be provided on the slack side if necessary. The above-mentioned U.S. patent specification discloses a wire drive machine in which a cushioning effect is imparted to at least the adjustment booth on the tension side, and although it is preferable to use this type of wire drive machine in the present invention, this is the only one. This cannot deal with the above-mentioned rocking of the barge.

それに伴フてクッションプーリが変位する。When the cushion pulley is supported by a hydropneumatic cylinder mechanism, the tension of the cutting wire is equal to its limit load, for example 1
When the pressure reaches 50 to 200 Kgf, the pressure regulating valve opens and the rod is displaced, and the cushion pulley is displaced to alleviate the increase in tension. Also, when the cushion pulley is supported by a spring or balance weight mechanism, the spring expands and contracts and the balance weight moves up and down depending on the tension of the cutting wire.
Accordingly, the cushion pulley is displaced.

。It has the same structure as the embodiment shown in FIG. 4, except that (22) is interlocked with an intermediate lobe (35). In this case, when the barge (3) swings upward, both cushion pulleys (21) and (22) move each arm (33) and (34).
), the cutting wires (25) are simultaneously displaced in the direction of the cutting object (1) as shown by the one-dot chain line and the two-dot chain line, thereby instantaneously relieving the increase in tension of the cutting wire (25). Note that the cushion pulleys (21) and (22) can also be provided non-interlockingly.

を水上から容易に切断することができる。As described above, according to the floating wire sawing method and device according to the present invention, the wire drive machine is operated on the barge, and the cutting wire that is stretched between the wire drive machine and the object to be cut is driven via the cushion pulley. Therefore, even if the barge swings, the object to be cut can be easily cut from the water without breaking the cutting wire.
