| Directional
Drilling techniques are used for the trenchless installation of new pipelines,
ducts, and cables. The drill path may be straight or gradually curved, and
the direction of the drilling head can be actively controlled during the
bore to steer around underground obstacles or under highways, rivers or
railways.
Installation of the product pipe or duct is usually a 2 stage operation. A pilot hole is first drilled along the required path, and the bore is then back-reamed to a larger diameter to accomodate the size of the pipe you are pulling back. The pipe comes back as the back-reaming is being carried out. |

Tracking
the bore head at all times enables the operator to keep an accurate log
of it’s exact position throughout the bore. The process is environmentally
friendly as no trees or vegetation is harmed in any way.
The bore head is tracked in and around other obstacles. Other electronic equipment, called “Subsite” is manufactured by DitchWitch and is used to locate underground assets. |
