METHOD FOR CUTTING CONCRETE STRUCTURE

PROBLEM TO BE SOLVED: To provide a method for cutting a concrete structure capable of dispensing with the alteration of a coolant supply position, preventing cutting work from being interrupted and always supplying a proper amount of a coolant at a proper position. SOLUTION: When the concrete structure P is cut, a coolant supply hole 5 is preliminarily bored in the cut surface 7 permitting the contact with a cutter 1 of the concrete structure P so as to be opened always and the concrete structure P is cut while supplying the coolant through the supply hole 5. The cutter 1 is an endless wire saw which is wound around the concrete structure P to cut the concrete structure P and the supply hole 5 is formed so as to pierce the concrete structure between the side surface 3 on a cutting start side and the side surface 4 on a cutting completing side being cutting scheduled surfaces thereof.
