Horizontal Directional Drilling

Speedy pipeline connection in Australia

In just three months Australian drilling contractor Dunstans Construction Group installed a 700-meter-long pipeline in Anglesea (Victoria). A 250 tonne HDD Rig from Herrenknecht played a key role in the achievement. Within a very short time the construction crew built a sea outfall with the machine, as well as pulling in the pipeline all the way back to the local water treatment plant.

New Line of Ditch Witch HD Backreamers Enhances Durability on HDD Jobsites

Ditch Witch has released a new line of HD (heavy duty) backreamers to help underground construction operators improve productivity and tool durability on horizontal directional drilling (HDD) jobsites. New to all model designs, the HD backreamers are now equipped with standard API threads to fit any industry drill under 100,000 pounds.

HDD productivity tools unveiled

When HDD drill manufacturer Vermeer spoke to its customers about becoming more efficient, the issues that came up were less about the equipment they were using, than all the processes that surround a horizontal directional drilling job.

Know Your Directional Drilling Bits

HDD rock drilling brings with it a number of technical challenges. The bidding process alone is challenging because often the customer who is requesting bids has little information available about ground formations. Many drilling contractors find themselves conjecturing about what kinds of conditions they will encounter on many jobs, especially when they’re unfamiliar with the area.

Sidewalker Redesign Increases Convenience, Power, Speed

Installing short utility runs beneath landscaping, driveways and sidewalks can be done even more efficiently – and faster – with newly redesigned Sidewalker earth-piercing tools by HammerHead Trenchless Equipment.

Pipe Express: fast installation through groundwater

Herrenknecht’s newly developed semi-trenchless method for pipeline installation has completed its third successful mission. South of Stockholm, using Pipe Express, Züblin Scandinavia AB installed a water pipeline more than a kilometre in length within 12 days. Groundwater lowering was not required despite a water level just below the terrain’s surface. Compared to conventional open cut construction the method has significantly less impact on the environment, while simultaneously minimizing costs.

Pipe dope ... facts and fiction

One of the last things that you think about when preparing for any drilling job is grease, but in reality, it should be one of the first. Inadequate lubrication can result in lost time, as well as money on a drilling rig. Using the wrong compound can also be as costly.

Advances in midsize HDD technology help underground contractors conquer rock

Rock drilling isn’t the beast it used to be. Technologies developed and refined over the last two decades – specifically in midsize horizontal directional drilling (HDD) systems – are allowing utility contractors and others in the underground construction industry to more easily and costeffectively bore through even the hardest rock.
