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.

Tubular rock anchor

A rock anchor includes an elongate tubular body which extends between a first end and an opposing second end and a cartridge contains a multi-component adhesive system in the tubular body. The cartridge has a rigid tubular housing within which at least one compartment is defined, and in which is contained an adhesive component of the system. The at least one compartment yields to volumetrically reduce under fluid pressure created by a fluid input into the housing, to thereby extrude the adhesive components.
