Drilling
Directional boring, commonly called horizontal directional
drilling or HDD, is a steerable trenchless method of installing
underground pipes, conduits and cables in a shallow arc along a prescribed bore
path by using a surface launched drilling rig, with minimal impact on the
surrounding area. Directional drilling or boring is used when
trenching or excavating is not practical. Directional boring minimizes
environmental disruption. It is suitable for a variety of soil conditions and
jobs including road, landscape and river crossings. Installation lengths up to
6,500’ (2,000m) have been completed, and diameters up to 56" (1,200mm) have been
installed in shorter runs. Pipes can be made of materials such as PVC,
polyethylene, Ductile iron, and steel if the pipes can be pulled through the
drilled hole. |
