TOR-AP Self-Drilling Anchors

TOR-AP Self-Drilling Anchors are threaded steel tubes with high tensile strength, used in anchor foundations in rock, soil with rock, and for the buried elements of cable-stayed towers. Their geometry allows for simultaneous drilling and injection, using the bar itself as the drilling tool and for grout conveyance.

The set of tubular drilling rods, which will also make up the final tension-resisting element, are spliced by threaded couplers, having at the end a sacrificial drill bit called a tricone, with characteristics compatible with the ground to be drilled.

After the installation of the tie rod with its well-defined characteristic elements (the free and bonded lengths), and after the grout's curing time has passed, the head accessories are installed and the Post-Tensioning is performed.

Threaded tubular elements in high-strength structural steel, developed for applications in:

• ✅ Rock anchoring
• ✅ Soils with rock layers
• ✅ Slope containment / Slope stabilization

Special geometry allows it to act as self-drilling rods, combining drilling and grout injection in a single operation.
