摘要： A directional boring apparatus is disclosed where the apparatus is controlled through a method which includes deviating a drill head 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 when a drill head cutting member is positioned within an arc of rotation through which the desired direction passes. The drill head is retracted when the cutting member is outside of the arc of rotation.

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 drill head for an apparatus for horizontal directional drilling. The drill head includes a device for detecting angular orientation, a holder for the device for detecting angular orientation, the device for detecting angular orientation being disposed therein, a hammer driven by a liquid and a drill bit. The holder, the hammer and the drill bit are connected head to tail along a longitudinal axis of a drill string with the holder at a proximate end of the drill head and the drill bit at a distal end of the drill head.

摘要： Underground drilling operation often requires connecting a drill tool (e.g., drill bit, backreamer, etc.) to a drill string. It is desirable to connect the drill tools to a drill string in a manner that facilitates quick and easy assembly and disassembly. Low torque coupling, commonly referred to as “torque-less” connection, can provide such functionality. The useful life and strength of such connections can be improved upon. The present disclosure provides a low torque coupling with improved strength and durability.

摘要： A drill bit suited for impact-assisted directional boring in rock includes a bit body having a frontwardly facing, circular main cutting surface having a number of main cutting teeth disposed thereon. A gage cutter extends radially outwardly from the main cutting surface, which gage cutter mounts at least one frontwardly facing gage cutting tooth thereon suitable for cutting in a circle during straight boring and over an angle defined by less than a full rotation of the bit in order to steer the bit. A heel on an outer side surface of the bit body at a position opposite to and behind the gage tooth provides a reaction surface for the gage cutter. The bit body and gage cutter have a nearly circular side profile along a front portion thereof such that a maximum radial clearance between the side profile and a side wall of a hole being drilled is not greater than about 10 percent of the radius of a circle cut by the gage tooth.

摘要： A method and system for controlling a horizontal directional drilling machine having a boring tool. A rate of rotation and a rate of thrust are selected by an operator. Controls allow an automatic boring operation mode to be initiated to maintain the selected rate of rotation and thrust without further input from the operator. Periodically, when the rotation and thrust are interrupted, such as to modify the drill string, the automatic boring operation mode is interrupted. The automatic boring operation mode may be resumed without requiring the operator to select the rate of rotation and rate of thrust. The rate of rotation is resumed before the rate of thrust to reduce drill string shock loads and increase drilling performance.
