GJ25 GJ28 GJ32 Hollow Anchor Rod System for Radial Reinforcement and Slope Stabilization

The 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 slurry holes and dust removal capabilities for efficient operation.

• Radial Reinforcement: Replaces traditional mortar anchors, ensuring complete grouting and pressure grouting capabilities
• Slope Reinforcement: Simple process with low cost, convenient construction and remarkable stabilization effects
• Foundation Pit Support: Reinforces building foundation pits with pressure grouting to improve surrounding rock conditions

The hollow anchor features a hollow fully threaded rod body, anchor head, grout stopper, backing plate, and nut. Each component is designed to maximize grouting efficiency and density, with mortar pressure reaching up to dozens of kilograms to penetrate surrounding rock cracks.

• Combines anchor and grouting pipe functions in one system
• Hollow design eliminates mortar loss from grouting pipe removal
• Full grouting capability with pressure grouting for superior project quality
• Excellent rod body centering with full-length mortar coverage to prevent corrosion
• Easy installation with backing plates and nuts requiring no on-site thread processing
• Compatible with specialized grouting pumps and anchor rod grouting technology
