Product Overview
Anchoring is widely used in tunnel for pre-support, slope, coast, mine, water conservancy projects, Building foundation, roadbed reinforcement and geological faulty treatment such as landslip, crack, and sink age, it’s irreplaceable in narrow construction environment.
⚓ ADVANTAGES
Self Drilling Hollow Bar Anchor System:
Comprised of a hollow threaded bar attached with a drill bit that performs drilling. The hollow bar allows air and water to freely pass through the bar during drilling to remove debris. After reaching the required depth, grout fills the hollow bar under pressure to completely cover the bolt.
Coupler:
Used to join hollow bars and extend the bolt length, allowing the anchor to be elongated based on project requirements.
Plate and Nut:
Installed according to the specific design requirements of the project to ensure structural stability.
Drill Bit:
A wide variety of drill bits can be selected based on specific ground conditions.
Frequently Asked Questions
What is a Self-Drilling Anchor System?
It is an advanced anchoring solution that combines drilling, anchoring, and grouting into a single operation. It consists of a hollow threaded bar that acts as both the drill rod and the anchor bolt.
In which environments are R25 and R32 anchors most effective?
They are highly effective in unstable ground conditions, such as loose soil, sand, gravel, and soft-to-medium rock formations, especially in narrow spaces where traditional anchoring is difficult.
Can the anchor length be customized?
Yes. By using couplers, multiple hollow bars can be joined together to reach the specific depth required by your project design.
How do I choose the correct drill bit?
Selection depends on the geological conditions. Cast bits are generally used for sand/gravel, while Tungsten Carbide (TC) bits are better for rock formations, and EXX bits are reserved for the hardest rock or concrete.
What is the purpose of the hollow center in the bar?
The hollow center allows for the passage of air or water during drilling to remove cuttings and serves as a conduit for high-pressure grouting once the target depth is achieved.
Are these anchor systems suitable for building foundations?
Absolutely. They are widely used for foundation reinforcement, roadbed stabilization, and geological fault treatments such as landslip prevention.
