How An Underground Horizontal Boring Machine Works Safely
An underground horizontal boring machine changes the way we put pipes into the earth. The working steps are simple but highly effective, allowing projects to finish quickly without blocking city traffic or breaking surface pavements. The machine works through three clear steps:
- Pilot Hole Drilling: The drilling tool goes into the ground at a steady angle between 10 to 23 degrees. The operator guides the drill head along a planned path under the roads or rivers.
- Hole Reaming: Once the drill head reaches the target point, workers take off the pilot bit and put on a bigger reamer. The machine pulls the reamer back to make the underground tunnel wider.
- Pipe Pullback: After the hole becomes wide enough, the product pipe is attached behind the reamer. The machine pulls everything back to lay the pipeline perfectly inside the clean hole.
Our designs use top-grade steel joints and thick drill rods to ensure the machine can handle heavy pulling force without breaking. This makes the job highly predictable and safe for your team.

Choosing The Right Horizontal Directional Drilling Rig For Your Project
Selecting a good horizontal directional drilling rig depends on your real ground conditions and the size of the pipeline you want to lay. Different soil types need different levels of rotation torque and mud pressure. For example, sandy soils need high mud flow to keep the tunnel wall from falling down, while hard clay needs high rotation force to cut through easily. YG Machinery offers various models to fit different job demands:
- Cylinder Push and Pull Models: Models like YG-160A and YG-320 use powerful hydraulic cylinders. They provide steady force and are perfect for controlled, high-precision jobs.
- Motor Push and Pull Models: Models like YG-180, YG-280, and YG-320A use heavy-duty hydraulic motors. They offer fast moving speed up to 20 or 30 meters per minute for quick cycle times.
- Mud System Integration: Our rigs include built-in mud pumps that deliver up to 320 liters per minute of mud flow. This washes out mud cuttings quickly and cools down the drilling tools during long runs.
