A Horizontal Directional Drill Rig (HDD) is a trenchless drilling machine used to install underground pipes, cables, and conduits without digging the surface.
It uses a guided drilling process to create a path under roads, rivers, or buildings. This method reduces noise, surface damage, and project downtime compared to open-cut excavation.
Main Components of HDD Drilling Machine
A HDD drilling machine consists of several key parts that work together to complete underground boring efficiently:
- Drill unit: Provides power for drilling and pulling back the pipe.
- Power head: Delivers torque and thrust for drilling progress.
- Hydraulic system: Ensures smooth and stable power transfer.
- Drill rods and reamers: Used for directional drilling and enlarging the borehole.
- Control system: Monitors drilling depth, pressure, and direction in real time.
The working process includes three main steps:
- Drilling a pilot hole.
- Reaming to enlarge the hole.
- Pulling the pipe or cable through the drilled path.
