Abstract
Disclosed are examples of methods and systems for cutting up a reinforced concrete mass, in which a drilling tool is provided. In various embodiments, the drilling tool comprises: a drill tube carrying a cutter member; a device for causing the drill tube to vibrate, the device comprising a vibration generator for generating longitudinal vibration in the drill tube; a device for injecting a drilling fluid at the distal end of the drill tube; and a device for moving the drill tube along its longitudinal direction. In the disclosed methods and systems, the reinforced concrete mass is cut up by drilling at least one hole with the help of the drill tool by causing the drill tube to vibrate while injecting the drilling fluid into the mass from the distal end of the drill tube.
