摘要： A steerable reamer and method for use in horizontal directional drilling. The reamer includes a carrier frame rotatably coupled to a reaming body, a carrier frame housing slidably coupled to the carrier frame, and an hydraulic cylinder for tilting the carrier frame relative to the carrier frame housing. The reamer may also include sondes for monitoring the position and orientation of the reamer during operation or a laser guidance system for automatically steering the reamer along a pilot bore.

摘要： A directional boring apparatus is disclosed where the apparatus is controlled through a method which includes deviating a drill head (16) from a straight path into a desired direction angled away from the straight path. The deviation is achieved by applying an axial force to the drill head (16) when a drill head cutting member (18) is positioned within an arc of rotation through which the desired direction passes. The drill head (16) is retracted when the cutting member (18) is outside of the arc of rotation.
