ABSTRACT:
Soil nails are placed in the ground by driving a first elongate tubular member into the ground, driving a second member into the ground through a bore defined by the first member such that the second member is guided by the first member into a position in which it forms an extended soil nail, the second member being fired from a launcher with sufficient momentum to enter the bore and travel to its extending position. The second member may also be tubular to extend the bore so that further members can be driven to form a telescopic nail. The first member is fired from a launcher using a sabot which also serves to arrest penetration of the member.
