Self-Drilling Anchor Rods TOR-APE

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 made of high-strength structural steel, developed for applications in:

• ✅ Rock anchoring
• ✅ Soils with rock layers
• ✅ Embedded precast elements

Special geometry allows them to function as self-drilling bars, combining drilling and binder injection in a single operation.
