Abstract
A rock anchor includes a cartridge positioned in an elongate tubular body and having a rigid tubular housing. First and second compartments are defined within the cartridge. First and second adhesive components are positioned within the respective first and second compartments and are fluidly separated by a partitioning wall. A mixer is positioned within the elongate tubular body at a leading end of the cartridge. A pressing member is positioned within the cartridge towards a trailing end and includes a bladed formation which is operable to sever the partitioning wall when the bladed formation is caused to advance towards the leading end in response to fluid flowing into the cartridge, to thereby force the first adhesive component from the first compartment and the second adhesive component from the second compartment towards the leading end and into the mixer.
