Product Description
Full Threaded Steel Self Drilling Rock Bolt Hollow Anchor Bar
Product Overview
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.
Application Scope
- Radial Reinforcement: Replaces traditional mortar anchors, ensuring complete grouting and pressure grouting capabilities while eliminating construction defects
- Slope Reinforcement: Provides simple, cost-effective stabilization of unstable slopes with convenient installation and remarkable results
- Foundation Pit Support: Reinforces building foundation pits with simple processes, pressure grouting capabilities, and improved surrounding rock conditions
Structural Design
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 dense filling, with pressure capabilities reaching dozens of kilograms to penetrate surrounding rock cracks effectively.
Key Features & Advantages
Dual Function Design
Combines anchor and grouting pipe functions into one system - serves as grouting pipe during installation and becomes permanent anchor after grouting
Full Grouting Capability
Hollow design eliminates mortar loss from grouting pipe removal, ensures complete pressure grouting for superior project quality
Enhanced Corrosion Protection
Accessories ensure perfect rod body centering, allowing mortar to wrap entire anchor length for corrosion prevention and long-term support
Simplified Installation
Easy installation of backing plates and nuts without on-site thread processing requirements
