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 is an irreplaceable solution in narrow construction environments.
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 during drilling to remove debris. After reaching the required depth, grout fills the hollow bar under pressure, completely covering the bolt.
Used to join hollow bars and extend the bolt length, allowing the anchor to be elongated based on project requirements.
Installed according to specific design requirements to provide necessary tension and stability.
Available in various designs to be selected based on specific ground conditions.
