Directional Drilling
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 then 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 done 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 into the ground by a 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.
