摘要:
A method, system and apparatus for plasma blasting pavement comprises an apparatus having a set of diamond cutting tools for creating a boreholes, a diamond saw, and a set of blast probes comprising a high voltage electrode and a ground electrode separated by a dielectric separator, wherein the high voltage electrode and the dielectric separator constitute an adjustable probe tip, and an adjustment unit coupled to the adjustable probe tip, wherein the adjustment unit is configured to selectively extend or retract the adjustable probe tip relative to the ground electrode and a blasting media, wherein at least a portion of the high voltage electrode and the ground electrode are submerged in the blast media. The apparatus saws the pavement at the parameter of the area to be removed, drills holes in the pavement, and inserts blast probes in the holes. The plasma blast breaks up the pavement in between the saw cuts.24
