Self-Drilling Anchor System
Self-Drilling Anchor System

The self-drilling anchor system is an advanced anchoring solution on the market. It provides stability in soil or rock formations and is a key anchoring system in rock reinforcement projects, ensuring safety and structural rigidity.
Our self-drilling anchor is equipped with different parts. At the drilling end is the anchor bit, which creates the borehole while facilitating grouting. The anchor bolt, serves as the primary support structure. The anchor coupler extends the bolt's length when necessary, while the anchor plate distributes surface loads to ensure stability. Finally, the anchor nut locks the system securely in place, completing the setup for optimal performance.

Applications

The self-drilling anchor system is a versatile solution with applications across various industries and projects. It is widely used in:

Slope and Rock Stabilization: Ideal for stabilizing slopes, retaining walls, and providing support in excavation projects.
Micropiling: Used to enhance foundation load capacity or control settlement of existing structures. Applications include pipeline and OHTL (Overhead Transmission Line) foundations, tunnel base piles, and noise barriers.
Tunneling: Ensures stability during tunnel excavation and long-term reinforcement.
Ground Anchoring: Effective for retaining walls, buoyancy control, avalanche protection, and embankment reconstruction projects.

Product Advantages
  • Anchor bars can be drilled directly into loose soils without needing casings to support boreholes.
  • Both rope threads and trapezoid threads are robust and optimized for rotary-percussive drilling, ensuring strong bonding with borehole grout.
  • Drilling, grouting and anchoring are performed in a single operation, saving time and effort.
  • The hollow core facilitates flushing during grouting and anchoring after drilling, enhancing performance.
  • Bars can be cut and coupled at any point, allowing for easy extension and customization.
  • A variety of drill bits are available to suit different ground conditions, ensuring adaptability to diverse projects.
