Abstract

Das Bohrwerkzeug besteht aus einem mit einem Bohrstrang verbindbaren Außenrohr (1) und einer in dem Außenrohr (1) unverdreh-, jedoch axial verschiebbar angeordneten Baueinheit (3) mit vom Druck der Bohrspülung beaufschlagbaren Reaktionsflächen zur Erzeugung einer auf die Baueinheit (3) in Sohlenrichtung wirkenden Axialvorschubkraft und Mitteln zu deren Einstellung. Die Baueinheit (3) umfaßt eine Kernbohreinrichtung (5), die ihrerseits ein eine Bohrkrone (6) tragendes, drehbar angetriebenes Kernrohr (7) und ein darin frei drehbar abgestütztes Innenrohr (8) aufweist, einen mit der Kernbohreinrichtung (5) gekoppelten, bohrspülungsbetriebenen Motor (4) sowie eine Fangeinrichtung (13) zum Heraufziehen der Baueinheit (3). Dabei weist die Baueinheit (3) unterhalb des Bereiches (31) ihres Drehsicherungseingriffs mit dem Außenrohr (1) eine Trennstelle mit einander zugewandten Ausschlußmitteln (32,33;34,35) auf, zwischen die zumindest ein rohrförmiges Verlängerungstück (36;37) für die Baueinheit (3) einfügbar ist.
