Grouted Hollow Anchor Rod and Injection Pipe for Micropile and Rock Foundation Stabilization
Product Overview:
Grouted Hollow Anchor Rod and Injection Pipe for Micropile and Rock Foundation Stabilization.This Grouted Hollow Anchor Rod combined with an injection pipe system is specifically engineered for micropile and rock foundation stabilization applications. Designed for high-pressure grouting performance and structural load-bearing, the anchor rod provides reliable support in weak soil or fractured rock environments. It ensures maximum adhesion and bonding between the grout and surrounding substrate, making it ideal for infrastructure reinforcement, tunneling, and deep foundation stabilization projects.
Hollow bolt components: hollow bolt body, stopper, backing plate, nut and anchor head (drill bit)
Models of hollow bolts: diameters are 25, 28, 30, 32, 50, etc., thicknesses are 3, 5, 6mm, etc.
The length of the anchor rod can be customized according to customer needs.
Material & Structure:
- Rod Type: Hollow steel rod
- Pipe System: Integrated high-pressure grout injection pipe
- Thread: Full-length or partial-thread options available
- Steel Grade: Q235、45#, 40Cr, customized on request
- Surface: Hot-dip galvanized or black steel finish

Features:
- High-load bearing capacity under compressive and tensile stresses
- Superior grouting efficiency and soil penetration
- Corrosion-resistant surface treatments for durability
- Easy installation with minimal drilling and preparation
- Versatile use in micropiles, tunnels, and slope stabilization
Grouting Hollow Anchor Rod are mainly used in railways, highways, tunnels, mines, water conservancy projects, slopes, dams, bridge foundations, rivers, seas and lakes, high-rise building foundations and building reinforcement projects.
Through the middle rod body to the bolt slurry, it can achieve the purpose of consolidating the broken rock mass, forcing the partition control and the rod body force locking, which can form support with the rock mass stably and quickly, and the rock mass can rise steadily.
Applications:
- Rock and soil anchoring
- Micropile foundation systems
- Dam and bridge foundation upgrades
- Tunnel reinforcement in fractured rock zones
