What Is a Paddle Rock Bolt?

The Paddle Rock Bolt features a unique flattened "paddle" geometry at the anchoring end. This design ensures optimal mixing of resin cartridges within the borehole, creating a superior bond even in fractured rock. By combining high tensile strength with controlled yielding capabilities, these bolts absorb significant energy during seismic events or rockbursts, preventing catastrophic support failure.

How Paddle Rock Bolt Works in Resin Anchorage and Yielding Ground Support

Our advanced paddle design optimizes resin mixing and anchorage performance, providing a unique dual-stage support system that adapts to dynamic ground pressures.

science

Paddle / Spring Resin Anchoring

  • 01

    Break Capsules

    The specialized paddle tip ruptures resin capsules cleanly upon rotation, preventing plastic film wrapping around the bolt.

  • 02

    Create 3D Mixing

    Asymmetrical paddle geometry generates high turbulence, ensuring mastic and catalyst are blended into a uniform high-strength matrix.

  • 03

    Form Full-length Bonding

    The mixing action forces resin into rock fissures, creating a superior mechanical interlock across the entire anchorage length.

compress

Yielding & Energy Absorption

  • 01

    Ground Pressure Increases

    When seismic events or convergence occur, the rock mass exerts heavy tensile loads on the installed bolt.

  • 02

    Smooth Bar Yields

    The unanchored smooth section of the bolt begins controlled plastic deformation without breaking.

  • 03

    Energy Absorbed

    By elongating, the bolt absorbs significant kinetic energy, maintaining structural integrity during large-scale ground movements.
