That is, in the above-described water injection method, even if water is supplied at a plurality of points, the supplied water is supplied to the back side of the wire saw by the rotating centrifugal force of the wire saw that is circularly driven in an endless state. , The wire saw will be insufficiently cooled and lubricated, the diamond will be worn early, or cutting chips will be mixed in the water that has been scattered.
There was a problem that a large amount of muddy water was scattered, which deteriorated the working environment and polluted the surrounding area.

To cope with such a problem, for example, at an actual work site, a rubber tube or the like is inserted into a groove cut by a wire saw, and the cutting groove is closed so that cooling water is rotated. However, this method cannot be used at the beginning of cutting when no cutting groove is formed, and in addition, simply inserting a tube into the groove will apply a considerable pressure to the cooling water, so sufficient sealing performance will be obtained.

By the circulation of the wire saw 5, first, the inner surface of the pipe 3a is cut, and then the cutting of the concrete structure 1 is started. At this time, the cooling water injected through the hose 7 tends to be pushed to the back side of the structure 1 due to the centrifugal force due to the circulation traveling of the wire saw 5, and the pipe 3a is arranged in this portion. Therefore, the cooling water flows along the pipe 3a in the traveling direction of the wire saw 5 and stays in the pipe 3a.

Therefore, from the beginning of cutting, the wire saw 5
Cooling and lubrication are secured by cooling water, diamond wear is prevented, and scattering of muddy water containing cutting chips on the back side of the concrete structure 1 is prevented. Then, the cooling water flowing along the traveling direction of the wire saw 5 reaches the front surface side of the structure 1 at the portion of the through hole 2,
The front seal part 4 is provided in this portion, and the flexible seal plates 4c and 4d are connected to the flexible saw plates 4c and 4d at the insertion positions of the wire saw 5 as shown in FIG. Since it is elastically deformed in the traveling direction and is in contact with the peripheral surface of the wire saw 5, the cooling water flows downward through the gap between the guide plates 4a, 4b and the flexible seal plates 4c, 4d, The cooling water is prevented from splashing outside.
