Abstract
A mobile system for manufacturing and installing rock reinforcing members in mining and tunnel construction applications where a plurality of holes are drilled into the rock and each hole receives a reinforcing member and grout. The reinforcing member can be steel strand or some other suitable material. The system has a plurality of cooperating devices, all mounted to a mobile self-propelled platform. The devices comprise a spool of reinforcing material, a motivating device for drawing material from of the spool through the system, a measuring device, a crimping device to give the steel strands a corrugated shape, an articulating arm with a guide head to guide the material into the drill hole and a cutter to cut the material into strands of desired length. A plurality of strands can be installed in a given drill hole. The system also includes apparatus for grouting the drill holes using either a cementacious grout or a polyester resin grout. Methods of making and grouting the reinforcing member are disclosed.
