Key Features

  • Hollow Design: The bar is hollow, allowing grout to be pumped through its center during installation. This ensures proper bonding with the surrounding soil or rock.
  • Self-Drilling Capability: Equipped with a sacrificial drill bit, the bar can drill directly into the ground without the need for pre-drilled holes or casing.
  • Threaded Surface: The bar's surface is threaded, enabling it to act as a reinforcement element once installed.

Applications

  • Soil Nailing: Stabilizing slopes and retaining walls.
  • Micropiles: Providing foundation support in weak soils.
  • Rock Bolting: Reinforcing rock masses in tunnels and mines.
  • Anchoring: Securing structures like retaining walls or bridge abutments.

Advantages

  • Efficiency: Combines multiple steps into one operation, saving time and labor.
  • Adaptability: Suitable for unstable soils where traditional methods may fail.
  • Durability: Provides long-term reinforcement and stability.
