Anchoring Casing Pipes for Ground Support Systems

Rock Drilling Tools

Anchoring Casing Pipes

The casing pipe is directly connected to the drilling rig, effectively preventing failure of casing advancement caused by casing or casing shoe breakage and ensuring smooth casing-follow drilling operations.
Extended round-thread design prevents casing separation as drilling depth increases. The round threads offer superior compressive strength and torsional resistance compared with other thread forms.
Triple-start thread design significantly reduces the risk of thread galling and seizure during long-term operation, ensuring easier disassembly after drilling.

In steep slopes and deep excavations with single-side anchoring, how do the anchoring drilling tools perform in terms of tensile resistance and self-drilling capability?

The anchoring drilling tools are manufactured from thickened high-strength steel with reinforced thread designs, ensuring reliable self-drilling performance, high tensile resistance, and safe pull-out operations in steep slopes, tuff formations, and backfilled ground. These systems are widely adopted in deep excavation and slope stabilization projects.

How do high-penetration anchoring drilling tools integrate with self-drilling anchor systems to ensure construction efficiency?

The anchoring drilling tools are fully compatible with commonly used self-drilling anchor systems, providing secure connections, fast penetration rates, and reduced risk of thread disengagement. They are well suited for projects with high daily output requirements and tight construction schedules.
