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 is an irreplaceable solution in narrow construction environments.
Frequently Asked Questions
What is a Self-Drilling Hollow Bar Anchor System?
It is a bolting solution that combines drilling, anchoring, and grouting into a single operation. The hollow bar serves as the drill rod, injection pipe, and reinforcement tendon simultaneously.
In which geological conditions is anchoring most effective?
It is highly effective for geological faulty treatments such as landslips, cracks, and sinkages, as well as for reinforcement in tunnels, slopes, and mines.
How do I choose the correct drill bit?
The choice depends on the ground condition. For example, steel cross bits are ideal for loose to medium dense soil, while TC (Tungsten Carbide) bits are recommended for soft to medium rock formations.
What is the purpose of the coupler in the system?
The coupler is designed to join multiple hollow bars together, allowing for the extension of the anchor length to meet specific project depth requirements.
Why is the hollow bar design beneficial for grouting?
The hollow center allows grout to be pumped through the bar under pressure, ensuring that the grout fills the borehole from the bottom up and completely encapsulates the anchor bar for maximum bond strength.
Are these systems suitable for narrow construction environments?
Yes, the system is specifically noted for being irreplaceable in narrow or restricted construction environments where traditional drilling equipment might not fit.
