The Types of Rock Bolts. A grouted rock bolt is a threaded bar made of steel, or rebar bolts. Once drilling is done and this steel bolt is inserted, cement grout or resin grout can be used as the grouting agent. For reinforcement, a cable bolt made of steel wires intertwined as a steel rope is placed with the grout in the borehole.

The Swellex rockbolt is a sealed steel tube folded on itself which upon installation is expanded with high water pressure offering strong performance and interaction with rock mass,

General Features. The DSI Underground OMEGA-BOLT® is an expandable rock bolt with excellent elongation properties designed to accommodate ground movement.

In general Swellex bolts strengthen the rock mass through a combination of friction and mechanical interlock at the rock-bolt interface. The anchoring mechanism of the Swellex bolt is actually different in hard and soft rocks. In hard rock, the secondary contact stress, induced by the mechanical interlock of the asperities at the borehole wall, plays a major role in the anchoring, whereas the primary contact stress, created by the bolt expansion does not contribute much.

The Swellex bolt is a folded steel tube, which is inserted into a pre-drilled hole in the rock. Water is blasted into the tube at high pressure, blowing out the fold and expanding the tube into the exact shape of the hole, adapting to every irregularity.
