United States / Canada [change]Road Bores
For highways and major roads with heavy traffic, pipeline contractors often use road bores to install the pipeline. The process begins by digging a bell hole using a hydraulic excavator next to the road to be bored. A boring machine is then suspended in place by a pipelayer that drills a hole under the road to allow insertion of the pipe.
Engineered for demanding work, Cat® Pipelayers and Hydraulic Excavators are state-of-the-art machines. For crossing most small roads pipeline contractors use the "open-cut" method using hydraulic excavators in which the ditch is dug through the road.
