The Process of Trenchless Boring

The trenchless boring process has three main stages. These are pilot drilling, expanding the hole, and pulling the pipe. Reliant Resources in Franklin, Tennessee, uses the latest bore pipe installation, drilling equipment, and horizontal drilling methods. They do this to make the process efficient and accurate³.

Preparation and Planning

Before starting, a lot of prep and planning are needed. This includes checking the site, finding underground utilities, and making detailed plans. This helps make the trenchless installation go smoothly and successfully⁴.

Equipment Used in Trenchless Boring

Drilling rig: This is the main tool, giving power and control to the drill head.
Drill head: It’s hollow inside and pushes through the ground, making the first hole.
Drilling pipe: These pipes connect to the drill head and help extend the bore as it drills.
Steering tools: Tools like Brownline’s Gyro Steering Tool help drill accurately and place the bore exactly⁴.

In the pilot drilling stage, a bentonite slurry keeps the hole open and removes soil. After the pilot hole is done, a reamer makes the hole bigger for the production pipe. Then, the production pipe is pulled through, finishing the trenchless installation³.

“Trenchless boring technologies, such as horizontal directional drilling and auger boring, have revolutionized the way we approach infrastructure projects, minimizing surface disruption and accelerating project timelines.”
