Abstract
A grout applicator including a grout tube adapted to detachably connect to a strata support cable or tendon, or a tensioning device associated therewith, for grouting an annulus between an elongate rock cavity and the support cable or tendon, the grout tube having a grout passageway in fluid communication with the annulus; and a clamp member movably coupled to the grout tube for clamping of the grout tube to the support cable or tendon, or the tensioning device, whereby in operation grout is injected into the annulus via the grout tube.
Claims23
A grout applicator comprising:
- a grout tube adapted to detachably connect to a strata support cable or tendon, or to a tensioning device associated with the strata support cable or tendon, for grouting an annulus between an elongate rock cavity and the support cable or tendon, the grout tube having a grout passageway in fluid communication with the annulus;
- and
- a clamp member movably coupled to the grout tube for clamping of the grout tube to the support cable or tendon, or to the tensioning device, grout during operation being injected into the annulus via the grout tube.
A sealing assembly for a strata support cable or tendon, the sealing assembly comprising:
- a tubular housing adapted to locate within an annulus between an elongate rock cavity and the support cable or tendon at or adjacent an opening of the rock cavity;
- and
- at least one sealing element connected to and radially extending from the tubular housing, the sealing element being adapted to at least in part contact a perimeter wall of the rock cavity at or adjacent the opening thereby reducing leakage of grout from the annulus via the opening.
