ROADWAY ACCESS HOLE CUTTER HAVING A UTILITY AVOIDANCE SAFETY DEVICE, METHOD OF CUTTING A HOLE IN A ROADWAY, METHOD OF CUTTING A HORIZONTAL HOLE UNDER A ROADWAY
A method of cutting a microtrench in which the buried utility is exposed by opening an access hole in a roadway above the buried utility using a roadway access hole drill that is controlled by a computer system connected to an under-roadway detection unit that detects a buried utility and stops movement of the drill to avoid damaging the buried utility. Also provided is a method of drilling a substantially horizontal hole under a roadway using a horizontal drill that is controlled by a computer system connected to an under-roadway detection unit that detects a buried utility and stops movement or changes direction of the drill to avoid damaging the buried utility.
