Mechanical Rock Bolt

The mechanical rock bolt is a new type of prestressed anchor bolt ingeniously combined with rock anchor bolts and end expansion shells. After the installation of the expansion shell grouting anchor bolt, the prestress is immediately provided by the opening of the steel expansion shell anchor fasteners, which can effectively control the loosening and deformation of the surrounding rock in a timely manner and promote the formation of a compressive stress ring in the surrounding rock within the anchoring range, further enhancing the reinforcement effect of the anchor bolt on the surrounding rock and the stability of the project.
