An emptying station (20) is attached to an upper end of the jacket tube, and the frame is fastened at the station, where the station has an unloading device (25) for removing the tools from drill cuttings. The unloading device is adjusted for retaining the drill cuttings and discharging the drill cuttings from the station. An independent claim is also included for a method for drilling a hole inside a jacket tube. |
