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 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 entire bolt.
The coupler can be used to join hollow bars and extend the bolt length, allowing the anchor to be elongated based on project requirements.
Essential components installed according to specific design requirements to secure the anchoring system.
A variety of drill bits are available, selected specifically based on the choice of ground conditions.
