Patent ID: 7367748

Claim:
A method of installing a tracer wire segment and a pipeline segment beneath an obstacle using a horizontal directional drilling process, the method comprising: positioning a horizontal directional drilling device on a first side of the obstacle; attaching a drill bit to an end of a flexible pipe that is driven by the horizontal directional drilling machine; driving the drill bit and the flexible pipe from the first side to a second side of the obstacle to form a bore wherein the drill bit exits the second side of the obstacle; removing the drill bit from the flexible pipe; attaching a reamer to the end of the flexible pipe; attaching an end of the pipeline segment to the reamer; attaching an end of tracer wire segment having a high density carbon steel core with a copper cladding and a high density polyethylene jacket to the reamer; reversing a direction of the drive of the horizontal directional drilling machine; and pulling the pipeline segment and tracer wire back through the bore from the second side to the first side of the obstacle wherein the end of the pipeline segment attaches to another segment of the pipeline proximate the first side and an end of the tracer wire segment attaches to another segment of the tracer wire proximate the first side.
