Reduce surface subsidence and preventing collapse effectively.
Improve bending strength and controlling inclination.
Large diameter anchor bolt can be applied to fault zones of excavations and tunnel portals.
It will improve wall strength and make excellent adhesive strength when used with high-pressure grouting.
