High Strength Full Threaded Steel Self Drilling Hollow Anchor Bolt System for Mining and Construction Support
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 slurry holes and dust removal capabilities for efficient operation.
- Radial Reinforcement: Replaces traditional mortar anchors, ensuring complete grouting and pressure grouting capabilities while eliminating construction defects
- 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 fully threaded rod body, anchor head, grout stopper, backing plate, and nut. Each component is engineered to maximize grouting efficiency and density, with mortar pressure reaching up to dozens of kilograms (specific parameters subject to design) to penetrate surrounding rock cracks.
Combines anchor and grouting pipe functions - serves as grouting pipe during installation and becomes permanent anchor after grouting
Hollow design eliminates mortar loss from grouting pipe removal, enables pressure grouting for superior quality
Excellent rod body centering ensures mortar wraps entire anchor length, providing long-term support durability
Backing plates and nuts install easily without on-site thread processing requirements
Integrated with specialized grouting pumps and anchor-specific grouting technology, this represents China's only anchor system that comprehensively addresses traditional solid support limitations.
