Abstract

The invention applies to the field of devices which are used to reinforce walls and vaults of tunnels or land in general.The invention includes a cylindrical rod, onto which a boring mill is attached externally to bore holes in the wall or vault of a tunnel.Eccentric bushings are inserted along the length of the cylindrical rod, each of which has a tooth which engages a corresponding number of cylinders parallel to the bushings in the opposite sense of rotation from ground-boring rotation.As the rod rotates in the boring direction, the external cylinders rotate together with the rod.The rotation in the opposite direction to the boring of the cylindrical rod causes the external cylinders to move against the wall of the hole bored by the rod.
