Horizontal directional drilling is a commonly used non-destructive construction technique.
It boasts the following features:
High Precision: Drills accurately along the designed path.
Construction is safer: reduces risks for workers operating outdoors.
Minimal environmental impact: Avoids extensive excavation and surface damage.
During the construction process, horizontal directional drilling is generally carried out in the following steps:
Guided hole drilling: Utilizing gages and other equipment to control the direction and depth of the drill bit, creating a guided hole.
Hole Expansion: Gradually enlarge the guide hole according to the pipeline diameter.
Reeling Pipe: Connect the pipe to the expander and lay the pipe to the designated position by reeling.
The horizontal directional drilling application is quite extensive, such as:
Install various underground pipelines, such as oil and water supply lines.
In areas unsuitable for large-scale excavation, such as bustling city districts and cultural heritage protection zones, pipeline construction is carried out.
