• FOREPOLING RING BIT SYSTEMS AND CASING TUBES

    Forepoling Ring Bit Systems are designed to be drilled with Top hammer or DTH in an umbrella shape as secondary support in the tunnel roof.
    Weak ground and overburden must be strengthened by grouting through the casing and grouting valves into the ground.

     

    Main applications for forepoling systems are:
    1. Forepoling or Tube Umbrella
    2. Anchoring
    3. Micro piling
    4. Fibre glass face stabilization
    5. PVC foundations
