Abstract

A closed tubular preferably circulary cylindrical rock stabilizer is made of expansible mild steel and given a perimeter equal to pi D. After being inserted in a drill hole of a diameter slightly larger than D, the stabilizer is expanded radially by hydraulic high pressure fluid past the value D to such an extent that the irregularities of the drill hole are filled and the rock widened elastically around the stabilizer to provide an anchoring shrinkage fit therefor.
