ABSTRACT:
The stabilizer comprises a generally tubular, metal body, the leading end of which has been hardened to rock-cutting strength in order that the stabilizer, according to the method of invention, can be impacted with a high frequency, low-blow actuator to cause the stabilizer to bore its own hole in the earth structure, this to eliminate a pre-boring, stabilizer installation step.
