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 the bar during drilling to remove debris. After drilling at the required depth is completed, grout fills the hollow bar through pressure and completely covers the entire 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 secure anchoring.
Selected based on the specific ground conditions of the construction site.
