47mm Friction Bolts Stabilizer For Ground Support

Product Description:

Split rock friction anchor system is also a split anchor system, which is composed of high-strength steel pipe (alloy steel strip) or thin steel plate and a perforated tray. From the appearance, it can be seen at the end of the anchor rod. A U-shaped cross-section and longitudinally grooved bolt. It is mainly used for support engineering projects and can be used in underground copper mines, recent mining, tunnel construction, bridges, dams and other infrastructure projects. In addition to the above areas, it can also be used to stabilize the ground and prevent erosion. The installation method of friction bolts is simple and the difficulty coefficient is low. It is an important advanced material in the field of engineering support projects today.

Product Installation

1.Drill holes according to specifications: Use a rock drill to drill holes in the ceiling or walls. The diameter of the hole will be slightly smaller than the diameter of the bolt.

2.Pay attention to keeping clean: Compressed air is recommended to clean the holes and remove dust and loose particles.

3.Insert the bolts: Insert the split friction bolt into the hole that exactly lines up with it, making sure the tray is resting on the surface of the ceiling or wall.

4.Installation: Place the installation tool on the bolt head and tap with a hammer until the bolt is fully installed. Tool and hammer strikes must be perfectly aligned with the bolt axis to avoid distortion. The bolt head deforms slightly to make contact with the ceiling or wall surface, creating friction that helps maintain stability.

5.Verification check: Verify bolt installation to ensure it is placed correctly and has the proper tension.
