METHOD OF STABILISING A ROCK STRUCTURE COMPRISING BORING A HOLE,INSERTING IN THE BOREHOLE A TUBULAR STABILIZER THAT IS SLIMMER THAN THE BOREHOLE AND EXPANDING THE TUBULAR STABILIZER TO ANCHOR IN THE BOREHOLE

摘要

Housing (1), made from plastic material with radial deformation, has a ring-shaped cross-section. The housing has an open end with flange (2). Elastic container (4) has an identical cross-section to the housing. Support plate (3) can interact with the flange. Container (4) is part of assembly tool (5). - When pressure is fed into container (4), it expands, pressing the housing against hole (11). The walls of the hole deform elastically. The pressure is removed from the container and tool (5) is removed, leaving the housing secured.
