Rock Bolts Works
They are iron skewers with multiple lengths ranging from 6 m to 12 m with a diameter of 32 mm. Their sizes are determined according to a specialized committee of technicians and engineers, and then they are punched using punching equipment that works on air pressure horizontally with inclinations above 15 degrees and a diameter of 64 mm. A specialized committee also determines
When these toothed skewers are inserted, the cement is injected with the grout material by means of a cement pump through a plastic tube into the perforation depths (grout injection). This cement material fills the cracks and gaps inside the rock and leads to linking these rocks together. These nails are then attached using nuts mounted on special galvanized iron pieces.
