  • the drilling tool is raised again via the crane device. Subsequently, the support frame is released from the jacket tube and the drill is pivoted overall laterally to the jacket tube. In this position, the box drill is emptied.
  • the drill is then placed back onto the casing tube, clamped the support frame and drained the drill again.
  • the drill rig When the drilling operation is completed, the drill rig is completely removed by means of the crane device, and the resulting cavity within the casing tube can be filled, for example, by introducing a steel reinforcing cage and a concrete mass to form a foundation pile.
  • This drilling process is overall very economical, since the drill can be moved to the completion of drilling on the crane device to another jacket tube, so that immediately after the next hole can be started. Since the drill can be moved quickly and efficiently via a cable suspension on a crane device, so to speak, a "flying drill" is created.
  • the invention has for its object to provide a drilling apparatus and a drilling method, with which an efficient creation of a hole in a casing pipe is possible even under adverse weather conditions.
  • the drilling apparatus is characterized in that an emptying station is provided for attachment to the upper end of the casing tube, wherein the support frame of the drilling device can be fastened to the emptying station, that the emptying station for emptying the drilling tool of cuttings has an unloading device which is adjustable for receiving the cuttings is, and that the unloading device is designed for conveying the cuttings from the emptying station.
