Tunneling & Mining
Cut-able solutions
Cut-able support is mostly used in the longitudinal direction of the tunnel (portal, face) when temporary stabilization is required before moving to the next phase. Also, Mechanized Tunneling is becoming standard in urban areas, especially for underground metro projects. This modern technique is calling for new kind of systems, in particular cut-able reinforcement bars for concrete structures (like Soft-Eyes in D-walls) and cut-able ground anchors.
Radial & lateral support (Roof & Wall)
When building a tunnel by drill & blast or conventional mining, the roof and walls need to be supported. Rock-bolts are the first type of support installed, before any other kind of mesh or lining is applied. Depending on the construction sequence and technology, both temporary and permanent bolts can be offered.
