KAT DRILLING
1 / 4
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.
Comprised of a hollow threaded bar attached with a drill bit. Allows air and water to freely pass through during drilling to remove debris. After reaching depth, grout fills the bar under pressure for complete bolt coverage.
Used to join hollow bars and extend the bolt length effectively. The anchor can be elongated to meet specific engineering requirements using high-strength couplers.
Plates and nuts are installed per design requirements. Drill bits are specifically selected based on the ground condition to ensure optimal drilling performance.
