The Horizontal Directional Drilling Process

drilling rig thus enlarging the pilot hole. Drill pipe is added behind the reamers as they progress toward the drill rig. This insures that a string of pipe is always maintained in the drilled hole. It is also possible to ream away from the drill rig. In this case, reamers fitted into the drill string at the rig are rotated and thrust away from it. Pullback Pipe installation is accomplished by ...

Drilling fluid - Wikipedia

In geotechnical engineering, drilling fluid, also called drilling mud, is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells.One of the functions of drilling mud is to carry cuttings out of the hole.

TECHNICAL CHECKLIST CONCRETE CORE TESTING

Drilling and storage are important for concrete of any strength, and following standard testing methods is especially impor-tant for high-strength concretes. When drilling holes to provide access for penetrations in a finished structure, the only goal is to provide an opening of the correct size and alignment. But when drilling is done to produce cores for strength testing, the goal is to ...

THE HISTORY OF DOWN-THE-HOLE DRILLING AND THE USE OF .

Down-the-hole drilling has been a feature of dam anchoring and rock mass grouting in the U.S. for many decades. Until quite recently, this rotary percussive drilling method was synonymous with the use of compressed air. Within the last decade, however, increasing use has been made of water-activated, down-the-hole hammers. These provide many significant advantages, especially for rock fissure ...

DTH Drilling - Robit Plc

DTH Drilling A down-the-hole drill, usually called DTH is mainly a pneumatic powered rock or ground drill, in which the percussive hammer is located directly behind the drill bit, so the percussion mechanism follows the bit down into the drill hole. The drill pipes transmit the necessary feed force and rotation to the DTH hammer [.]
