Guided Pipe Reaming

Guided Pipe Reaming

Guided Pipe Reaming is a trenchless method by which a pipeline is pulled into the ground after a pilot tube is installed on line and grade. This method is similar to Horizontal Directional Drilling (HDD), however instead on installing pilot rods from the surface and following a shallow arc that is suitable for pressure lines and electrical utilities, Guided Pipe Reaming is a pit launch application that installs pilot rods on line and grade without the requirement of oversized pullback reamers.

GBM Case Study – Guided Pipe Ramming

The Port Mann/ Highway 1 Improvement Project (PMH1) was executed as a design-build project. Its purpose was to mitigate traffic congestion, improve safety for vehicles and pedestrians, improve environmental habitat, and re-implement public transit in greater Vancouver.
