Horizontal Directional Drilling is a trenchless method for installing a product that serves as a conduit for liquids, gasses, or as a duct for pipe, cable, or wire line products. It is a multi-stage process consisting of site preparation and restoration, equipment setup, and drilling a pilot bore along a predetermined path and the pulling the product back through the drilled space. When necessary, enlargement of the pilot bore hole may be necessary to accommodate a product larger than the pilot bore hole size. This process is referred to as back reaming and is don at the same time the product is being pulled back through the pilot bore hole.
Alignment of the bore is accomplished by proper location of the drill bit head as it is being pushed in the ground by the hydraulic jack. Location and tracking of the drill bit is determined by an above ground radio detection device which picks up a radio signal generated from a transmitter located within the drill bit head. Radio signal is then electronically translated into depth and alignment. In order to minimize friction and prevent collapse of the bore hole, introduction of a soil stabilizing agent (drilling fluid) is introduced into the annular bore space from the trailing end of the drill bit. The rotation of the bit in the soil wetted by the drilling fluid creates a slurry. The slurry acts to stabilize the surrounding soil and prevent collapse of the bore hole as well as provides lubrication.
