Abstract (en)
[origin: EP1978204A1] The device has an encasing tube (5) surrounding an auger (4). A twin-head rotary drive (20) drives the auger in a rotating manner about a drilling axis. An ejecting device (10) discharges drill spoil from the auger, where the ejecting device has a telescopic discharge line (11) i.e. discharge pipe, for the drill spoil. A winch device changes the length of the line. The line extends longitudinally to a mast element (3) in a direction of a drilling axis. The auger is moved together with the ejecting device along the mast element. A hoisting cable is fixed to tube elements (14, 14', 14''). An independent claim is also included for a method for producing a borehole in the ground with an earth drilling device.
