Abstract
A resin input nozzle (10A) which is adapted to engage or connect to a hollow resin-anchored rock bolt (12) to introduce a resin composed of a plurality of resin components (A,B,C), into and through the bolt, the nozzle including a body (14) with a leading end (16), a leading end portion which ends at a leading end and a trailing end (18), a first conduit (22) and a second conduit (24) formed through the body, each conduit having an outlet (28A, 28B), which opens at or adjacent the leading end, and at least one inlet (26A, 26B) which is adapted to engage with a supply of a respective resin component, wherein the outlets are spaced from one another to prevent mixing of the resin components as each emerges from a respective outlet after passage through a respective conduit.
Claims6
A resin input nozzle which is configured to engage or connect to a hollow resin-anchored rock bolt to introduce a resin composed of a plurality of resin components, into and through the bolt, the nozzle comprising:
- a body with a leading end, a leading end portion which ends at the leading end, and a trailing end;
- a first conduit and a second conduit formed through the body, separate from one another, each of the first and second conduits having an outlet, which opens at or adjacent the leading end;
- and
- at least one inlet which is configured to engage with a supply of a respective resin component,
- wherein the outlets are spaced from one another to prevent mixing of the resin components as each emerges from a respective outlet after passage through a respective one of the first and second conduits by the first and second conduits diverging, at least towards the leading end, with each of the outlets opening through a side-wall of the body, thereby laterally spacing the outlet of the first conduit from the outlet of the second conduit.
