  • Publication number: 20200173281
    Abstract: A bung has a body which extends between a leading end and a trailing end and which includes an inner part of a rigid material which has a cylindrical aperture for receiving a rock bolt and an outer sealing part of a resiliently deformable material circumscribing the inner part. The inner part and the outer part engage at an interface which has a co-efficient of friction which allows the outer part to disengage from the inner part at the interface when a shear force above a predetermined level is applied to the outer part or the inner part.

  • Patent number: 10174616
    Abstract: Disclosed is a cable anchor assembly including: a cable anchor body longitudinally extending between leading and trailing ends; a tensioning device with an outer member having first and second ends and a threaded through passage between the ends and an inner member which threadedly engages the threaded passage of the outer member and fixedly attached to the cable anchor body at or towards the trailing end; a faceplate engaging the cable anchor body between the leading end and the tensioning device. In use, with the cable anchor body inserted in a borehole and anchored therein, the faceplate positioned against a rock face and the first end of the outer member abutting the faceplate, the outer member is rotatable relative to the inner member, causing the inner member to move within the passage towards the second end of the outer member, drawing on the cable anchor body, tensioning the body.

  • Publication number: 20170184434
    Abstract: The invention provides a breather tube indicator device which includes a sealing body which is adapted to fit within a breather tube of a grouted rock support installation to allow passage of air past the body, without the body moving relatively to the tube, but to resist passage of an adhesive material thereby to cause movement of the body relatively to the tube to an indicating position.

  • Patent number: 9200514
    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.

  • Patent number: 8985910
    Abstract: 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.
