Additional information
| Outer diameter | 32–111 mm |
|---|---|
| breaking load | up to 3650 kN |
| material | steel |
| Product Name | Анкерная бурильно-нагнетательная система (SDA) |
| Applications | ► Reinforcement of fractured and disturbed zones during development and extraction operations |
| 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 rock masses through anchoring ► Reduces labor requirements by combining multiple technological operations into a single process |
| Operating Principle | These are hollow anchor bolts that combine borehole drilling and subsequent anchoring in a single operation. They are used for rock stabilization, foundation reinforcement, tunnel support, slope stabilization, and other geotechnical applications. |
| Packaging | Packaged in bundles of up to 30 pieces, depending on the anchor diameter. |
| Storage | Dry and enclosed storage area. |
| Equipment | Drilling rig (hydraulic or pneumatic) — provides rotation and feed of the anchor. Grout injection pump — injects cementitious/polymer grout through the hollow bar. Auxiliary equipment (couplers, centralizers, adapters) — for extending the anchor length and ensuring accurate positioning. |
