    R38N Self Drilling anchor rock bar / anchor rod / anchor bolt

    R38N Self Drilling anchor bolt/ anchor rock bar / anchor rod
    Self Drilling Anchor Bolts are a bolting solution for unstable ground conditions such as sand, gravel, silt, and clay, and in soft to medium fractured rock formations.
    For projects facing such ground conditions, self-drilling anchors should be considered as the main productivity solution. Self-Drilling Anchors from Anchoring are designed for optimized installation, tailored to the project’s needs.  self-drilling anchor bolt is composed of a hollow anchor bolt, anchor nut, anchor plate, anchor coupler, drill bit, and centralizer. By drilling a hole in collapsing soil or loose rock, with an efficient hollow bar and a drill bit, and after the drilling operation injecting grout into the hollow bar and surrounding cavity, self-drilling anchors are a top productivity solution.

  • swellex rock bolts Hydraulic Expansion Friction Bolts for slope stability Underground Tunnel Arch split set rock bolts

    swellex rock bolts Hydraulic Expansion Friction Bolts for slope stability Underground Tunnel Arch split set rock bolts

    The Hydrabolt is a hydraulically expanded rockbolt with superior bond strength for tensile loading applications. The hollow, tubular Hydrabolt is injected with high pressure water upon installation and then expands to adapt to the shape of a predrilled support hole. The Hydrabolt incorporates a check valve to prevent the fluiofrom being released once the inflating nozzle is removed. This system provides abetter bond as the inflated tube adapts to the shape, size and irreqularities of thehole and distributes the clamping force evenly throughout the length of the hole As the installed Hydrabolt is sealed, the internal corrosion is self-inhibiting Hydrabolts are fitted with an integral load indicator that confirms it has been correctly installed by popping forward once the Hydrabolt has been adequately pressurized; secondly the color of the load indicator identifies which length of Hydrabolt has been installed
