The self-drilling anchor system is an advanced geotechnical solution designed for efficient ground reinforcement and stabilization. The system comprises several key components, including a hollow anchor bar, nut, bearing plate, coupler, centralizer, and drill bit. By integrating drilling, grouting, and anchoring into a single process, this system is particularly effective in challenging ground conditions such as fractured rock masses and unstable surrounding strata where conventional drilling methods often fail.
One of the system’s major advantages is its ability to function without the need for a casing pipe, significantly enhancing construction efficiency. This streamlined approach reduces project timelines and lowers overall costs while maintaining high structural integrity. The hollow anchor bar serves a dual purpose: it acts as a drill rod during installation and later functions as the primary reinforcement once grouted. Additionally, the bar can be cut to any required length and extended using couplers, making it highly adaptable for confined or narrow workspaces where large drilling equipment cannot operate.

The self-drilling anchor system is widely used in various engineering fields, including:
Slope stabilization (preventing landslides and erosion)
Foundation support (enhancing load-bearing capacity)
Tunnel and underground engineering (pipe roofing, excavation support)
Transmission tower and wind turbine foundation reinforcement
Retrofitting and strengthening existing structures (buildings, bridges, retaining walls)
It is particularly valuable for pre-construction support, improving the stability of soil and rock masses before excavation or structural work begins.
Integrated Reinforcement
Superior Bond Strength
High-Strength Material
Time and Cost Efficiency
Minimized Waste
For additional safety, especially for international shipments, these self-anchor drilling system tools will be packed in standard package, ensuring superior strength and resistance to rough handling, moisture, and other potential hazards during long-distance transportation.
