PROBLEM TO BE SOLVED: To rapidly and efficiently bore a continuous groove by efficiently combining reinforcement part cutting with a wall saw and impact boring with an SD machine in partially demolishing/removing a reinforced concrete structure 1. SOLUTION: The arranged positions of reinforcements 3 are detected beforehand, and a continuous slit 6 is bored with the wall saw 10 from the surface 2 of the reinforced concrete structure to a part deeper than the detected disposed positions of the reinforcements along a ridgeline on one side of a continuous groove of predetermined width to be bored. Each reinforcement is separated at one part, and a position in the continuous groove of predetermined width to be bored, adjoining the slit is bored with an impact boring machine 20 from the surface of the reinforced concrete structure. The reinforcements in an area corresponding to the predetermined width are thereby cut/removed, and further the continuous groove 7 of predetermined depth is bored using the same impact boring machine.
