PROBLEM TO BE SOLVED: To provide a method and a device for chipping the reinforced concrete capable of evenly chipping as much as possible a lower part of a vertical beam, a lower part of a lateral beam and a lower part of an intersection of the vertical beam and the lateral beam. SOLUTION: A nozzle 6 of a high-pressure fluid jet ejecting mechanism 5 for ejecting the high-pressure fluid, while always tilting forward in the traveling direction, is moved on a cradle 3 in the direction inclined in relation to the reinforcement. In order to form a strip chipping part WO having the predetermined width F, the strip chipping part is moved in the direction, in which the nozzle 6A crosses the cradle traveling direction FW, and the cradle 3 is made to travel. |
