DYWIDAG Cable Bolt
Flexible reinforcement system with post-tensioning option.
- Ground Support
The DYWIDAG Cable Bolt is a pre-tensioned, bulbed cable tendon designed to be installed as a long rock bolt. Used in underground hard rock mines, DYWIDAG Cable Bolts help ensure a safe working environment by increasing rock mass stability.
Manufactured from 19 wire strands having a nominal diameter of 21.8mm cross-section, the cable bolts are capable of being post-tensioned at the face to withstand with a post-tensioning force of up to 25 tons. The system uses mixed resin to fill the borehole. The top end of the bolt provides a very efficient anchorage by using a unique combination of a spiral resin mixer and a choice of up to 3 bulbs.
- High-strength system for permanent or temporary reinforcement, with tensioning possible
- Available in lengths up to 10 meters, and can be cut to any length for easy on-site length adjustment
- Unique combination of a spiral resin mixer to ensure thorough combination of resin and hardener
- Anchorage strength of the resin-grouted top end of the bolt exceeds bolt tensile strength in typical rock conditions
- Easy to handle and adapt to confined working spaces
- Can be used in combination with other support systems such as shotcrete, mechanical bolts, or grouted rebar for complete flexibility
