摘要: A hollow bar (3) and a method of manufacturing the hollow bar are disclosed. Typically, the hollow bar is a threaded rock bolt or a drill rod. The hollow bar (3) comprises two or more elongate members (21a, 21b) connected together along the longitudinal edges (41) of the members (21a, 21b). The method comprises rolling the members (21a, 21b) and welding or gluing the members (21a, 21b) together along the longitudinal edges (41) of the members (21a, 21b).

摘要: The invention provides an injection, sealing, valving and passageway system for use with hollow rock bolts and hollow injection bars used in mining, civil engineering, tunneling and construction including use with hollow self drilling rock bolts. The invention comprises a plurality of passageways with one or more one way flow valves along the passageways. The invention enables one or more fluids to be pumped into a hollow rock bolt or other hollow elongate member either sequentially or simultaneously without cross contamination of fluids in another passageway or back flow of fluids along the wrong passageway. The invention is typically used to install self drilling rock bolts whereby a drilling fluid is initially pumped through the hollow bolt during the drilling cycle, and then a two part chemical resin or cement grout is pumped through the hollow bolt to anchor the bolt in the borehole.
