As described above, when a wire saw is used underwater, the distance from the electric motor on land increases as the water depth increases, and therefore a wire saw with a long length is required. It is uneconomical because it is uneconomical, and when the wire saw is long, it has the drawback that the wire saw receives water resistance and requires a large amount of power, and there is a certain length between the pulley on the electric motor shaft and the cutting point. Since the endless wire saw of is engaged,
If the distance between the electric motor and the cutting point fluctuates, a large load is suddenly applied to the wire saw, causing damage to the electric motor or spinning of the wire saw.Therefore, the distance between the electric motor and the cutting point should not fluctuate. It is necessary to install the electric motor in a place where it is not shaken by the waves, such as on a ship, but it is difficult to fix the ship completely. Therefore, if the electric motor itself is installed near the cutting point in the water, the length of the wire saw will be shortened and the above drawbacks will be eliminated, but not only the electric motor needs to be waterproof, but also the endless wire saw will be pulled and rotated. There is a drawback that the large diameter pulley for receiving it receives the resistance of water and cannot obtain a predetermined rotational force.

According to the present invention, the length of the wire saw can be shortened by fixing the mounting base of the dry closed chamber having the pulley for winding the wire saw near the object to be cut in water. Since an expensive wire saw can be obtained at low cost, and the length of the wire saw is short, it is not only easy to handle, but also the resistance of water received by the wire saw is reduced, and the control of the pulley is performed near the object to be cut. Even if the control room is swayed by operating on land, on a barge or on a workboat, the wire saw may be suddenly loaded or run idle because the distance between the pulley and the object to be cut is constant. There is no fear, especially because the large diameter pulley that winds the wire saw is in the dry space inside the dry closed chamber, so there is no resistance to water, so no extra power is required. Constant of the rotational force can be obtained.

According to the second aspect of the invention, since the dry closed chamber provided with the large pulley for winding the wire saw in the dry space is connected so as to be pulled on the mounting base, the length of the wire saw is short. Well, since the wire saw rotates under the dry closed chamber, water does not enter the dry closed chamber and the large pulley can rotate in the dry space inside the dry closed chamber, so it is possible to work underwater. Work efficiency is high without being affected by water resistance.

According to the third aspect of the present invention, when the dry closed chamber is submerged in water, even if water accidentally enters the chamber, the water can be removed by supplying air from the compressor, and various signals from the sensor can be received. The computer immediately responds to the hydraulic motor for the pulley, the hydraulic cylinder for the mounting base, and the hydraulic cylinder for the fixed clamp, to optimize the rotational speed of the pulley and hence the rotational speed of the wire saw, and to cut the dry closed chamber near the object to be cut. It can be securely fixed to the optimum position of the rock bed etc. by the fixing clamp provided on the mounting base.
