Diamond Wire Saw Dry-Cutting Method

A wire saw apparatus for cutting a structure using a dry method, the wire saw apparatus comprising:

• a main roller;
• a first roller unit located at one side of the structure, the first roller being configured to allow a cutting wire introduced from the main roller to pass therethrough such that the cutting wire is directed to the structure so as to surround the structure;
• and
• a second roller unit located at the other side of the structure, the second roller being configured to allow the cutting wire moving while surrounding the structure to pass therethrough such that the cutting wire is transferred to the main roller, wherein
• the first roller unit comprises a first fixing roller, a first auxiliary roller configured such that at least a part of the first auxiliary roller is in contact with an outer circumferential surface of the first fixing roller, a first guide roller configured to guide the cutting wire introduced from the main roller to the first fixing roller, and a second auxiliary roller configured such that at least a part of the second auxiliary roller is in contact with an outer circumferential surface of the first guide roller, and
• the second roller unit comprises a second fixing roller configured to allow the cutting wire moving while surrounding the structure to pass therethrough, a third auxiliary roller configured such that at least a part of the third auxiliary roller is in contact with an outer circumferential surface of the second fixing roller, a second guide roller configured to guide the cutting wire introduced from the second fixing roller to the main roller, and a fourth auxiliary roller configured such that at least a part of the fourth auxiliary roller is in contact with an outer circumferential surface of the second guide roller.
