Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. Directional boring offers significant ...
The force generated by CIRT is concentrated in a localized area, minimizing threats to the safety of survivors and the potential destabilization of the surrounding structure. A self-contained tool, CIRT does not require the drilling, chipping, or sawing used by traditional methods to reach survivors trapped under collapsed concrete.
