Abstract
Die Erfindung betrifft eine Bohrvorrichtung und ein Verfahren zum Horizontalbohren. Die Bohrvorrichtung umfasst einen Bohrkopf, ein Bohrgestänge und eine Antriebseinrichtung, welche zum Drehantrieb und Vorschubantrieb des Bohrgestänges ausgebildet ist. Das Bohrgestänge weist ein Innengestänge und ein Außengestänge auf, zwischen denen ein Ringraum zum Leiten einer Spülflüssigkeit von einem Drehanschluss zu dem Bohrkopf ausgebildet ist. Das Innengestänge umfasst einen Richtraum, welcher sich von der Antriebseinrichtung bis zu einem bohrkopfseitigen Abschlusselement erstreckt. In dem Richtraum ist zumindest ein Teil einer Zieleinrichtung zur Richtungskontrolle des Bohrkopfes angeordnet. The invention relates to a drilling apparatus and a method for horizontal drilling. The drilling device comprises a drill head, a drill string and a drive device, which is designed for rotary drive and feed drive of the drill string. The drill pipe has an inner rod and an outer rod, between which an annular space is formed for conducting a flushing fluid from a rotary connection to the drill bit. The inner rod comprises a straightening space, which extends from the drive device to a drill head end element. In the directional space at least part of a target device for directional control of the drill head is arranged.
