Have you ever faced these challenges in complex geological conditions like coal mines, tunnels, and water conservancy projects?
1. Overburden pressure is immense, leaving conventional anchor rod support inadequate?
2. Surrounding rock is loose and fractured, making it difficult to ensure anchoring strength and posing safety hazards?
3. Construction efficiency is low, impacting overall project progress?
4. Purchased support products are mismatched with on-site geological conditions, significantly reducing effectiveness?

working principle of friction bolt
The friction bolt is tightly inserted into a borehole with a diameter smaller than its own. After installing the anchor plate (where it contacts the retaining ring), the anchor rod is driven into the borehole using installation tools until the plate tightly contacts the rock surface. As the tube advances under pressure, its slotted section closes, generating radial pressure across the entire contact surface with the rock mass. This forces the rock mass and anchor rod to bond together, with the high-strength tray bearing significant rock pressure. Thus, a complete friction support system is formed.
advantage of friction bolt
1. It provide seamless support for rock and soil formations. The system uses a special anchoring technique to provide full-column grouting and helps to ensure that the bolt remains tightly in place throughout its lifespan.
2. The installation of split sets is a quick and easy install
Installing split sets is a relatively quick and easy process, and they can provide a high level of support with minimal equipment. However, it is important to follow proper safety procedures and guidelines when installing split sets to minimize the risk of accidents or Injuries.
3. No anchoring agent required;
4. Environmentally friendly. They are designed to withstand harsh weather conditions and resist corrosion, reducing the need for frequent replacements and helping to lessen the environmental impact of construction projects.
5. Norminal size: diameter 33mm, 39mm, 46mm, 47mm or customize
