Product Description
Hollow Self Drilling Injection Anchor R51L 51mm
The R51L Hollow Self Drilling Injection Anchor combines drilling, grouting, and anchoring functions into a single integrated system. This 51mm diameter anchor bar delivers reliable performance in challenging ground conditions with ultimate load capacity of 550 kN and yield load of 450 kN.
Applications
Ideal for unstable geological conditions including broken rock, loose soil, fault fracture zones, decayed rock, gravel, sandy gravel, and backfill ground. Various drill bit options available for optimal performance across different soil types.
Project Applications
- Permanent tunnel excavation support systems
- Slope stabilization and rock bolting for structural reinforcement
- Micro pile reinforcement to transfer structural loads and limit building deformation
Key Features
- Casing-free operation: drill pipe serves as anchor bar for time-saving installation
- Synchronous or post-drilling grouting effectively fills fractures with excellent spread radius
- Standard thread screw design allows cutting or lengthening for narrow space applications
- Enhanced bonding stress through continuous wave and T-thread technology
