high strength split set anchor bar
Friction bolt consists of only two 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 had a welded ring flange to hold the 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.
Brief description:
1.Friction rock bolt
2.Made of high-tensile alloy steel plate
3.Big friction between bolt and rock
4.The height of tunnel must be larger than the bolt length
5.High yield and tensile strength, and easy to install
Structure:
1.The tube is made of high-tensile alloy steel plate;
2.High-strength face plate;
3.No need resins and cement cartridges;
4.Big friction between bolt and rock;
Features:
1.Easy to install;
2.High yield and tensile strength;
3.The height of tunnel must be larger than the bolt length.
