What Does Rock Bolts Mean?
Rock bolts are long bolts that anchor or support excavation by penetrating deep into the stronger portion of the rock and holding fast. Once the rock bolt is anchored, a compression force is set up into the surrounding rock. Trenchless methods of pipeline installation such as microtunneling and pipe jacking require excavating launch and exit pits for workers to operate equipment from.
Unstable rock formations can be dangerous for workers and equipment if they fall. Rock bolts can be used to hold up excavated pits by anchoring them into loose formations along with strong meshing.
