Abstract:
A rock anchor assembly includes a rock anchor with a flexible element and first/second cylindrical connector elements engaged to proximal and distal ends of the element, a flexible tubular sleeve longitudinally extending between first and second ends, on the rock anchor so end parts of the rock anchor project from sleeve ends; a load bearing barrel centrally bored engaging the first connector element between the first end of the sleeve and a proximal end of the rock anchor, the barrel engaging the first end of the sleeve in sealing contact, the barrel having a grout conduit between the barrel exterior and the bore, the conduit defining part of a grout passage interconnecting the barrel exterior and sleeve interior, when the barrel engages the sleeve; a seal preventing grout outflow but accommodating grout inflow; a tensioner engaging the first tubular connector element, and a mechanical anchor engaging the second tubular connector.

Claim (Index 13):
A method of anchoring a rock anchor assembly within a rock hole, the rock anchor assembly including a flexible outer sleeve which extends between a first end and a second end; a rock anchor which locates, at least partially within the sleeve, such that end parts of the rock anchor extend beyond the first end and the second end of the sleeve, the rock anchor comprising a flexible cable and a first and a second cylindrical connector element engaged to a proximal end portion and a distal end portion respectively, with the first cylindrical connector element carrying a mechanical anchor which is at least partly held within the sleeve in a closed position and the second cylindrical connector element being at least partly threaded, a faceplate located over the sleeve, a barrel on the threads of the second connector element and a fastener on the threads between the barrel and a proximal end of the rock anchor, the method including the steps of pre-spacing the barrel from the first inlet end or the fastener from the barrel, inserting the rock anchor assembly into a predrilled rock hole, a distal end of the rock anchor leading, until the faceplate is sandwiched between rock wall and the sleeve or the barrel and pushing the anchor further into the rock hole to close the pre-spacing allowing the rock anchor to move relatively to the sleeve to drive the mechanical anchor from the first end of the sleeve and into a radially expansive open position in which the mechanical anchor resistively engages the walls of the rock hole.
