The Zhengde hollow anchor system consists of five key components: hollow drill pipe, plastic drill bit, grout stopper, backing plate, and nut. The engineering plastic drill bit features specialized slurry holes and dust removal capabilities.

Hollow anchors replace traditional mortar anchors for radial reinforcement, eliminating common construction defects such as incomplete grouting and inability to achieve pressure grouting, ensuring superior project quality.

For unstable slope reinforcement, hollow anchors offer simple processes, cost efficiency, quick installation, and remarkable stabilization results.

Building foundation pit reinforcement using hollow anchors provides straightforward processes while enabling pressure grouting to enhance surrounding rock conditions.

The hollow anchor system comprises a hollow fully threaded rod body, anchor head, grout stopper, backing plate, and nut. Each component is engineered to maximize grouting efficiency and density, with mortar capable of penetrating surrounding rock cracks under pressures up to dozens of kilograms (specific parameters subject to design requirements).

The hollow anchor combines anchor functionality with grouting pipe capabilities in a single integrated system. During grouting, it functions as a grouting pipe, then becomes a permanent anchor without removal after grouting completion.

• Hollow Design: Eliminates mortar loss from grouting pipe removal in traditional construction
• Full Grouting: Enables pressure grouting implementation for enhanced project quality
• Superior Centering: Accessories ensure optimal rod body alignment with complete mortar coverage, preventing corrosion and enabling long-term support
• Easy Installation: Backing plates and nuts install effortlessly without on-site thread processing
• Complete System Solution: Combined with specialized grouting pumps and anchor-specific grouting technology, this represents China's only anchor system that comprehensively addresses traditional solid support limitations
