SELF DRILLING ANCHOR BOLT

A hollow-core anchor system for one-step drilling and grouting in tough ground.

SELF DRILLING ANCHOR BOLT Combining drilling and grouting into a single hollow-core operation, the Hollow Anchor System is composed of six essential components: Hollow Anchor Bar, Drill Bit, Coupler, Domed Nut, Domed Plate, and Centralizer.

Made from high-strength alloy steel, the Hollow Anchor Bar is a fully threaded, hollow-core rod engineered to perform reliably in challenging geological environments. Its hollow-core structure allows drilling and grouting to be carried out simultaneously, shortening installation time while creating a stronger bond between the ground and the anchor. The system is designed for use in projects requiring stabilization under demanding ground conditions, such as mining, tunneling, and slope stabilization.

• Hollow Injection Anchor: Achieves both drilling and grouting in a single operation.
• Reduced Setup Time: No casing required, saving time and resources on-site.
• Enhanced Strength: Withstands in both tension and compression.
• Space-Saving Design: Performs efficiently in tight spaces with lightweight drilling equipment.
• Swift Installation: Simplified and fast assembly process.
• Adjustable Length: Easily extended or terminated with couplers and domed nuts to match project requirements.
• Applications: Meets complex geotechnical needs for slope stabilization, micropile foundations, and tunneling.
• Customized Solutions: Tailored options available to meet specific project and ground conditions.
