Product Overview

Hollow anchor rods are innovative anchoring solutions designed for rock support, slope stabilization, and underground construction. Featuring a seamless hollow core, these rods enable efficient grouting and cement injection, ensuring superior bonding strength and long-term durability.

Hollow anchor rods Ideal for mining, tunneling, and civil engineering projects, they offer a cost-effective alternative to traditional solid rods while maintaining exceptional load-bearing capacity.

Key Features

  • Hollow Core Design‌: Allows direct grouting through the rod, eliminating the need for external pipes and simplifying installation.
  • High-Strength Material‌: Manufactured from premium steel, with options for corrosion-resistant coatings to suit harsh environments.
  • Enhanced Load Capacity‌: Optimized thread patterns and cross-sectional design distribute stress evenly, reducing failure risks.
  • Versatile Applications‌: Suitable for soft to medium-hard rock formations, soil stabilization, and retaining walls.
  • Easy Installation‌: Lightweight yet robust, reducing labor costs and time on-site.

Technical Specifications

  • Material‌: Alloy steel (ASTM A572 Grade 50 or equivalent).
  • Diameter Range‌: 22mm to 32mm (customizable).
  • Length Options‌: 1.5m to 6m (tailored to project needs).
  • Surface Treatment‌: Hot-dip galvanized or epoxy-coated for corrosion resistance.
  • Grouting Compatibility‌: Works with cement, resin, or chemical grouts.

Why Choose Our Hollow Anchor Rods?

  1. Efficiency‌: The hollow design accelerates grouting, cutting installation time by up to 30%.
  2. Safety‌: Reduces exposure to hazardous environments by minimizing manual grouting steps.
  3. Cost-Effective‌: Lower material and labor costs compared to solid rods, with no compromise on performance.
  4. Global Standards‌: Complies with international certifications (ISO, CE, ASTM) for quality assurance.
  5. Customization‌: Available in lengths, diameters, and coatings tailored to your project’s geology.

Applications

  • Mining‌: Support for underground tunnels and shafts.
  • Civil Engineering‌: Slope stabilization, bridge foundations, and retaining walls.
  • Tunneling‌: Reinforcement in soft ground or fractured rock zones.
  • Disaster Prevention‌: Landslide mitigation and seismic retrofitting.

Installation Guide

  1. Drilling‌: Drill a hole to the required depth and diameter.
  2. Insertion‌: Place the hollow rod into the hole, ensuring alignment.
  3. Grouting‌: Inject grout through the rod’s core until full saturation.
  4. Curing‌: Allow grout to set before applying load (typically 24–48 hours).
  5. Testing‌: Conduct pull-out tests to verify bond strength.

Quality Assurance

  • Pre-Shipment Inspection‌: Each batch undergoes rigorous testing for tensile strength, thread integrity, and corrosion resistance.
