What Is Horizontal Directional Drilling?

The field of construction equipment operation continues to grow year-over-year. But with so many types of heavy equipment available, how are you supposed to choose which one to specialize in? Don’t stress; we’re here to help.

 

Horizontal directional drilling (HDD) is an ever-expanding field that offers various benefits to construction workers of all experience levels. Want to know whether it’s right for you? Keep reading to learn more.

What It Is, & What You’ll Learn

How HDD Works

Horizontal Directional Drilling is an advanced drilling technique used in the construction industry to install underground infrastructure—like pipelines, cables, and more. Since the entire process takes place underground, it doesn’t require trench digging—which saves you time and money.

 

The drill forms an arced tunnel that starts at an entry point and reaches an exit point on the opposite end. Although this drill path is predetermined, advanced drill location technology allows operators to modify the path mid-drill if needed.

What You’ll Learn in HDD Training

In addition to learning the basic principles of directional drill operation, students of our Ditch Witch-certified HDD program learn how to:

  • Communicate effectively with a team
  • Follow safety best practices
  • Implement traffic control and other preventative measures
  • Perform equipment inspection procedures
  • Perform proper PPE inspections
  • Conduct proper job planning and job site preparation, including any underground locates and requirements for the directional boring plan
  • Prepare emergency response plans

Why Is HDD Used?

Horizontal directional drilling is used for various reasons. Check out the main benefits of this drilling method.

  • It allows construction crews to install pipes and other materials with greater ease
  • It’s more efficient and cost-effective than alternative drilling methods
  • This trenchless method creates minimal soil disturbance and environmental impact
  • It’s extremely accurate
  • It requires less post-drill cleanup, allowing teams to restore the ground to its pre-drill condition quickly and easily

The Three-Stage Process of Horizontal Directional Drilling

If you’re wondering how horizontal directional drilling works, we’ve got you covered. Take a look below at our three-step guide to achieving effective drills.

Pilot Hole

Here’s how to get started.

  • Drill a small pilot hole in the ground.
  • Next, pump drill fluid through the drill pipe to the drill bit. The bit and the pressurized drill fluid will break through dirt and other materials along the way, creating a bore path. The drilling fluid will return the excavated materials—which are called the cuttings—to the drill rig.
  • The drill head contains a transmitter or steering tool that sends a location signal to the operator.
  • This component enables the operator to track and adjust the pilot hole to ensure more accurate drills.
  • Once the beacon housing and drill bit reach the exit point on the other end, a reamer replaces them.

Pre-Reaming

Now it’s time to pre-ream the pilot hole. This process involves expanding the hole to a size large enough for product line installation.

  • While the reamer recedes and rotates, it pumps additional drill fluid to separate and remove solid debris that obstructs the bore path. This drill fluid also helps prevent future obstructions from forming.

Pipe Pullback

Last but not least is the pipe pullback.

  • The drill rod and reamer are fastened to a swivel.
  • The swivel prevents torsional stress—which is the rotational force experienced by the drill string during the drilling process—between the product line and reamer.
  • The product pipe enters the drill hole, and drill fluid enters it—acting as a lubricant to ensure a clean and seamless installation.
