PRODUCT DESCRIPTION:
The split set is a slottedsteel tube with one end tapered for easy insertion into a drill hole. The other end has a welded ring flange to hold the bearing plate.
The stabilizer is insertedi into a hole slightly smaller in diameter than the tube, using a simple driver too fitted to the drill. As the tube enters, its diameter is compressed and the slot partially closes. This exerts radial forces along the length of contact with the rock, providing the friction which holds the rock together. The driving force of the drill actively loads the bearing plate against the rock.
APPLICATIONS: Split set friction rock stabiliser is used for underground or surface support in many applications.
DOMED BEARING PLATE:
Split set domed bearing plates uniquely combine high strength with light weight, and are integral parts of the split set system.
ACCESSORIES:
Bearing plate, Driver, Pull collar
FEATURES&ADVANTAGES:
Made from high strength steel band
Immediate frictional support in axial and radial
Independent supporting withour plate
Easy for installation
Simple design, cost saving
Available in black, cold galvanized or hot dip galvanized
HOW DOES SPLIT SET ROCK BOLTS AND FRICTION BOLTS WORK:
Split sets are rock bolts with only 2 parts,a tube and matching domed bearing plate. The high strength steel tube is slotted along its length. One end is tapered for easy insertion into a drill hole and the other has a welded ring flange to hold the bearing plate. With the bearing plate in place, the tube is driven into a slightly smaller hole, using the same standard percussion drill that made the hole. As the tube of the rock bolt slides into place, the full length of the slot narrows,causing radial pressure to be exerted against the rock over its full contact length.
