Abstract

Bei einem Verfahren zum drehenden und/oder schlagenden Bohren von Löchern in Erd-, Boden- oder Gesteinsmaterial und Festlegen einer Verankerung in dem Bohrloch wird durch eine an einem Bohrgestänge (4) gelagerte Bohrkrone (2) ein Bohrloch ausgebildet, sowie ein das Bohrgestänge (4) umgebendes, an einer von einer Abbaufläche abgewandten Rückseite der Bohrkrone (2) ange­ordnetes Anfängerrohr (3) gleichzeitig mit der Bohrkrone (2) in das Bohrloch ein­ gebracht wird, wobei ein einen Längsschlitz (8) aufweisendes Verankerungselement (9) nach dem Fertigstellen des Bohrlochs durch ein Zurückziehen entgegen der Bohrvortriebsrichtung aufgeweitet wird, wobei ein einen gegenüber einem benachbarten Bereich des Anfängerrohrs (3) größeren Durchmesser (5) aufweisender Bereich des Anfängerrohrs (3) in ein an einem Bereich kleineren Durchmessers (7) des Anfängerrohrs (3) angeordnetes, einen Längsschlitz (8) aufweisendes, hülsenförmiges Verankerungselement (9) zurückgezogen wird, sowie eine Vorrichtung hierfür.In a method for rotary and/or percussive drilling of holes in earth, soil or rock material and for establishing an anchoring in the borehole, a borehole is formed by a drill bit (2) mounted on a drill pipe (4), and the drill pipe ( 4) surrounding starter pipe (3), arranged on a rear side of the drill bit (2) facing away from a mining area, is introduced into the borehole at the same time as the drill bit (2), with an anchoring element (9) having a longitudinal slot (8) after completion of the borehole is expanded by pulling back against the drilling advance direction, with a region of the beginner pipe (3) having a larger diameter (5) than an adjacent region of the starter pipe (3) being converted into a region of smaller diameter (7) of the starter pipe (3). arranged, sleeve-shaped anchoring element (9) having a longitudinal slot (8) is retracted, as well as a device for this.
