Additional information
| Outer diameter | 32–111 mm |
|---|---|
| breaking load | up to 3650 kN |
| Product Name | Self-Drilling Anchor (SDA) System |
| Applications | ► Reinforcement of fractured and unstable zones during mine development and extraction operations ► Foundation-free anchoring of equipment ► Waterproofing of underground mine workings and excavations ► Injection of polymer resins into cracks and fractures within disturbed rock masses ► Used as sacrificial drill rods, anchor bars, and grout injection tubes. The threaded profile allows the rods to be extended with couplers and used with various drill bits, nuts, and bearing plates. |
| Component Description | Self-Drilling Anchor (SDA) System |
| Key Advantages | ► Enables drilling of boreholes and subsequent injection of polymer resins into rock formations of any strength and degree of fracturing ► Provides additional reinforcement of the rock mass through anchoring ► Reduces labor requirements by combining multiple installation processes into a single operation |
| Operating Principle | SDA anchors are hollow anchor bars that combine borehole drilling and subsequent anchoring in a single operation. They are used for rock stabilization, foundation reinforcement, tunnel support, slope stabilization, and a wide range of other geotechnical applications. |
| Packaging | Packaging: Supplied in bundles of up to 30 pieces, depending on the anchor diameter. |
| Storage | Store in a dry and enclosed indoor area. |
| Equipment | Drilling rig (hydraulic or pneumatic) — provides rotation and feed of the anchor. Grout injection pump — injects cementitious/polymer material through the hollow bar. Auxiliary equipment (couplers, centralizers, adapters) — for extending the length and ensuring accurate positioning. |
