Split Set Anchor
Split Set Anchor – Self-Expanding Friction Anchor for Instant Rock Reinforcement
Core Concept:
A high-strength steel tube with longitudinal slots, designed to expand radially when installed in a pre-drilled borehole. The friction between the anchor and the rock wall creates immediate load-bearing capacity, eliminating the need for grouting or resin.
Key Features:
- Material: Q235 carbon steel (ASTM A36 equivalent) or high-strength alloy steel (custom options available)
- Surface Treatment: Hot-dip galvanized (HDG) for corrosion resistance in harsh environments
- Design: Full-length slots ensure uniform expansion and consistent friction grip
- Installation: No additional equipment required – hammering alone achieves full anchoring

3. Why Choose Split Set Anchors?
✅ Instant Support: Provides immediate load-bearing capacity upon installation, critical for unstable rock conditions.
✅ Cost-Efficient: No grouting or resin required – reduces material and labor costs by up to 40%.
✅ Versatile Applications: Ideal for coal mines, tunnels, slope stabilization, and underground utility projects.
✅ Durable: Hot-dip galvanized surface resists corrosion in humid or chemically active environments.
✅ Easy Installation: Workers can install 50+ anchors per day with minimal training.
4. Global Applications
- Coal Mining: Roadway support in high-pressure zones (e.g., Australia, Indonesia, South Africa).
- Tunneling: Railway and highway projects (e.g., Chile, Canada, India).
- Slope Stabilization: Open-pit mines and landslide-prone areas (e.g., Peru, Philippines).
- Underground Structures: Metro tunnels, hydropower stations, and military bunkers.
5. Installation Guide (Simplified)
- Drill: Create a borehole slightly larger than the anchor diameter.
- Insert: Place the anchor into the hole.
- Expand: Lightly hammer the anchor to force the slots open, creating friction against the rock.
- Secure: The anchor locks into place, providing immediate support.
No grout, no resin, no delays – just pure friction-based reinforcement.
