Abstract

Eine Bohrvorrichtung zum Herstellen von Bohrlochverzweigungen in Lockergestein umfaßt einen voll verlaufsgesteuerten Pilotbohrkopf (14) mit einem daran angebrachten Bohrgestänge (40), wobei der Pilotbohrkopf (14) eine Öffnung (42) am Umfang, ein Ablenkteil (50) im Inneren des Pilotbohrkopfes (14), sowie Austrittsöffnungen (34, 36) für eine versteifend wirkende Bohrsuspension aufweist. Ein Innenbohrkopf (44) ist in Längsrichtung des Pilotbohrkopfes (14) bewegbar und durch das Ablenkteil (50) aus der Bahn (54) des Pilotbohrkopfes (14) ablenkbar. Nach dem Erstellen einer Pilotbohrung durch den voll verlaufsgesteuerten Vortrieb eines Pilotbohrkopfes wird eine versteifend wirkende Bohrsuspension aus dem Pilotbohrkopf ausgebracht und der Innenbohrkopf auf dem Ablenkteil im Pilotbohrkopf aufgefahren und somit eine abzweigende Bohrung durch das Vorrücken des Innenbohrkopfes erstellt.
