tunneling support fiberglass rock bolt Solutions Just Right For You

12.02.2013Rock bolts are an essential component of the New Austrian Tunneling method. As with anchor bolts, there are many types of proprietary rock bolt designs, with either a mechanical or epoxy means of establishing the set. There are also fiberglass bolts which can be cut through again by subsequent excavation. Many papers have been written on methods of rock bolt design. TUF-BAR fiberglass rock bolts utilize our strongest load-bearing GFRP fiberglass rebar. With ideal applications in Hard Rock Mining, Ground Stabilization, Salt Mines, Tunneling, and Tibacks, they are used in both permanent and temporary ground support applications and are non-corrosive, non-magnetic, and non-conductive.

A rock bolt is a long anchor bolt, with systematic use documented at the St Joseph Lead Mine in the US in the 1920s. Rock bolts were applied to civil tunneling support in the US and in Australia, starting in the late 40s. Rock bolts were used and further developed, starting in 1947, by Australian engineers who began experimenting with four metre long expanding anchor rock bolts while

between the bolt and the rock can be filled with cement or resin grout. Dowels or anchor bars generally consist of deformed steel bars which are grouted into the rock. Tensioning is not possible and the load in the dowels is generated by movements in the rock mass. In order to be effective, dowels have to be installed before significant movement in the rock mass has taken place. Figure 1
