ABSTRACT:
A grout gun for filling a rockbolt borehole with measured doses of grout includes a grout breech for accommodating a predetermined quantity of grout, which is usually in the form of a grout capsule. An elongate rubular barrel extends from the grout breech. Catalyst dosing means, comprising a catalyst dosing chamber communicating with the grout breech and a catalyst inlet pipe, provide a measured dose of catalyst. A compressed air inlet communicates with the catalyst dosing chamber, and a manual trigger valve is provided for controlling the flow of compressed air through the inlet. The valve is operable to propel both the measured dose of the catalyst and the predetermined quantity of grout simultaneously through the barrel under influence of the propellant. An accumulator may be provided downstream of the compressed air inlet, for accommodating a predetermined quantity of compressed air each time the trigger valve is operated.
