Abstract

PURPOSE: To drill an anchor hole in a floor or a wall without noise and vibration by providing a sprocket for supporting one end part of a nozzle through a second spherical surface bearing mounted with eccentricity, thereby braying the nozzle tip by rotation of the sprocket. CONSTITUTION: In the case of drilling, an anchor hole E in a floor A, a jet nozzle N is located in a drilling position, a suction box 5 is evacuated to suck and fix the device in a floor, and a protective cover is fixed to a ceiling. Subsequently, a motor 13 is driven to rotate a drive transmitting sprocket 10 through a driving sprocket 14 and a chain 15. With rotation, the tip (lower end) of a jet nozzle N is braied at a run-out angle 6 about a first spherical surface bearing 7 to drill an anchor hole E in a floor A by a high pressure water jet mixed with granulated material jetted from the tip of the nozzle N without vibration and noise. Subsequently, slurry liquid is recovered from the cover 3 and the protective cover through a hose 4.
