The hollow anchor system combines anchoring and grouting functions into a single unit, featuring a hollow fully threaded rod body, anchor head, grout stopper, backing plate, and nut. Constructed from ASTM 304/316 stainless steel, this system delivers exceptional durability and strong structural support for various construction applications.

• Radial Reinforcement: Replaces traditional mortar anchors, ensuring complete grouting and pressure grouting capabilities for superior project quality.
• Slope Reinforcement: Provides simple, cost-effective stabilization of unstable slopes with quick installation and remarkable results.
• Foundation Pit Support: Enhances building foundation pit reinforcement through pressure grouting that improves surrounding rock conditions.

• Hollow design functions as integrated grouting pipe, eliminating mortar loss during installation
• Full-pressure grouting capability ensures complete mortar penetration into rock cracks
• Excellent rod body centering provides complete mortar coverage, preventing corrosion for long-term support
• Easy installation with pre-threaded components requiring no on-site thread processing
• Compatible with specialized grouting pumps and anchor-specific grouting technology

Complete assembly includes hollow drill pipe, engineering plastic drill bit with slurry holes and dust removal, grout stopper, backing plate, and nut.
