Thanks to the rapid development of production technologies and a higher amount of mechanical excavation, GRP systems have gained importance in underground construction around the world. Fields of application of GRP Anchors and Rock Bolts range from cuttable rock bolts for underground coal mining or ground control for mechanical excavations to injection lances or forepoling. DYWIDAG-Systems International provides a diversified portfolio of GRP systems for various applications in Mining, Tunneling, and Civil Engineering which is completed by longtime experience in the production and application of GRP Anchors and Rock Bolts. 3

4 Fields of Application Rock reinforcement and rock support in underground excavation Mechanical excavations TBM, roadheaders, and continuous miners Cuttable ground control system for underground coal mining Injection lance for DYWI Inject Systems Forepoling element Tunnel portals and temporary rock reinforcement to be removed by excavators Ground stabilization in special foundations Main Advantages Lightweight system ensures an easy application in challenging conditions High tensile load-bearing capacity Tough and durable, yet easy to cut using mechanical excavators or shearers Enhanced corrosion resistance Anti-static components EX-proof system Tough and resistant threadform adjusted to the demands in surface and underground construction System Description Composite system consisting of high-strength glass fibers and high performance resin Bars manufactured according to the demanding requirements of the construction industry Available in different versions Type CS: fully threaded solid bars Type CH: fully threaded hollow bars Type CR: fully threaded self-drilling hollow bars with advanced, resistant composite structure Flat and round bars type MN Reinforcing bars and composite mesh Application in combination with concrete, cement grout, anchor mortar, or resin, depending on the application System Components Type CS Fully threaded solid GRP bar GRP plate GRP nut Type CH Fully threaded hollow bar GRP plate GRP nut Type CR Single-use drill bit different designs and dimensions available Fully threaded self-drilling hollow bar GRP plate GRP nut Flat and round bars type MN Flat or round GRP bar, optionally available with an angle cut on the far end and a driver tool adapter GRP plate, domed or square version Barrel and wedge anchorage 4
