Mining Friction Bolt Split Set Rock Bolt

1. High-strength alloy strip steel is used as raw material. One end is forged with a tapered head for the anchor bar to insert the hole, and the other end is welded with an iron hoop to bear the weight of the plate.

2. Installation is simple and can be completed only by impact.

3. Anchorage agent is not required.

4. The friction between the anchor bar and the rock mass is high.

5. It has high shear and tensile strength.

6. Equipped with a high-strength tray, the tray is evenly stressed.

7. The drilling depth is greater than the anchor bar depth.

8. It can provide timely support in radial and axial directions. It is unfit for permanent support in soft rock.

1. First, lay the steel mesh sheet along the top of the roadway, determine the hole position of the bolt according to the construction requirements, and then drill the hole with a drill pipe 1-2 cm larger than the diameter of the pipe seam bolt

2. After drilling, use pressure air to clean the rock powder in the hole to reduce the stone sticking.

3. Drive the pipe joint bolt into the hole with a ram drill with the tray.
