GEO-DRILL ANCHOR BAR

   Daqianrock Anchor System is today’s solution for a fast and efficient anchoring system into virtually any type of soil.  The system has historically been known as a “self-drilling anchoring” because the hollow fully-threaded bar serves as both the drill string and the grouted anchor, thus installation is performed in a single operation.  The sacrificial drill bit is threaded onto the end of the Hollow Injection Bar and left in place following drilling.  The drilling fluid (air, water, or grout) is introduced through the hollow bar and allows the spoils to flush from the borehole.

APPLICATIONS FOR DAQIANROCK ANCHOR SYSTEM

   Soil Nails are non-tensioned, in-situ reinforcement for the stability of excavations and embankments in top-down construction. Daqianrock Anchor System is an ideal choice for soil nailing in difficult soils as it offers high installation rates.  Anchor bar soil nails have been used extensively on private and select DOT permanent soil nail walls for years.  With the 2015 edition of the FHWA Geotechnical Engineering Circular #7, anchor bar soil nails are specifically addressed and allowed for use in non-corrosive ground conditions.

Advantages of the Daqianrock Anchor System for soil consolidation

• 1. Fast, single-step anchoring system with simple equipment.
• 2. Eliminates the need for a cased borehole in collapsing soils.
• 3. Efficient installation since drilling and grouting can be performed in a single operation, saving both time and money.
• 4. Continuously drilling and grouting under high pressure causes the grout to permeate into looser soils and creates a bulb-effect for increased bond capacity.
• 5. Multiple ranges of drill bits suitable for most soil conditions.
• 6. Installed with standard track drill (top hammer) or hand-held drilling equipment, eliminating the need for larger casing rigs.
• 7. Continuously threaded bar pattern can be cut and coupled anywhere along its length.
• 8. Corrosion protection systems available upon request.
