Self Drilling Anchor Plates

Self-drilling anchor plates are crucial components of self-drilling anchor systems, designed to effectively transfer the load from the anchor bar to the working face, such as rock or soil surfaces. These plates are engineered for optimal performance in various geotechnical applications like slope stabilization, tunnel support, and foundation reinforcement. Their key features often include:

• Robust Material Construction: Typically made from high-strength steel, often hot-rolled, to ensure durability and a high load-bearing capacity. Some variations may feature corrosion-resistant coatings like zinc alloy, zinc-plating, or epoxy for extended lifespan, especially in challenging environments.
• Load Distribution: Designed with a specific size and thickness (e.g., 150x150x8mm, 200x200x10mm, up to 250x250x60mm for larger anchors) to effectively spread the stress from the anchor bar over a wider area of the surrounding ground, preventing localized failure.
• Compatibility: Manufactured with specific hole diameters (e.g., 27mm, 35mm, 56mm, 80mm) to seamlessly fit corresponding self-drilling anchor bars and nuts, ensuring a secure and efficient connection.
• Versatile Design: Available in various forms, including flat plates and domed (spherical) plates, to suit different project requirements and ground conditions, and can often be customized in terms of specifications like size and thickness.

Unstable ground conditions and structural vulnerabilities pose significant challenges in construction and infrastructure projects. Addressing these issues effectively demands a robust and adaptable anchoring solution. Self-drilling anchor plates, as integral components of self-drilling anchor systems, provide a versatile and efficient answer across a multitude of applications.

• Pre-supporting: They are extensively used for pre-supporting in tunneling and mining operations, providing immediate stability to the excavation face and enhancing worker safety.
• Micropiling for Foundation Underpinning: Ideal for underpinning existing foundations, these plates work with self-drilling anchors to transfer structural loads to more competent ground, rectifying settlement and increasing bearing capacity.
• Slope Anchorage: Critical for stabilizing unstable natural or excavated slopes, preventing landslides and erosion, and ensuring long-term geotechnical stability.
• Retaining Wall Construction: Employed in conjunction with retaining walls to provide active or passive support, resisting lateral earth pressures and enhancing the wall’s overall stability.
• Dam and Bridge Repair: Used in remedial works for existing structures, offering effective reinforcement and extending the service life of vital infrastructure.
• Tunnel and Cavern Support: Provide essential systematic or localized support within tunnels and caverns, particularly in fractured or weak rock masses, to maintain excavation integrity.
• Special Foundations: Utilized in various special foundation designs where traditional piling methods are challenging or uneconomical, offering a rapid and adaptable solution.
