How Split Set Rock Bolts and Friction Bolts Work?

When a slotted anchor is installed in a hole smaller than the diameter of the pipe, three forces are exerted on the surrounding rock: radial pressure on the hole wall over the full length of the slotted anchor, friction to stop the surrounding rock from sliding down the hole, and the support force of the slotted anchor pallet. These three forces make the surrounding rock more stable.

TECHNICAL FEATURES

 

Quality assurance, simple installation

The raw material of pipe-seam anchor adopts high-strength alloy strip steel to determine the hole position of anchor according to the design requirements, and drill the hole with drilling machine, install the anchor disk on the rod, and drive the anchor into the hole with impact drill.
Punch the anchor into the hole.

High friction between the anchor and the rock mass

Three forces will be exerted on the surrounding rock, a radial pressure on the hole wall over the full length of the slotted anchor, a friction force to stop the surrounding rock from sliding down, and the bearing force of the slotted anchor pallet pallet, which makes the surrounding rock more stable.
