Full Threaded Forged Self Drilling Anchor Bolt System

Available in sizes R23, R32, R38, R51, T76 for ore mining, tunneling, and slope stabilization applications.

Product Overview

A high-strength anchor bolt system designed to transfer structural and geotechnical loads into stable rock formations. The complete system includes hollow threaded rod, drill bit, coupling, anchor plate, grouting stopper, and nut. Manufactured from high-strength seamless steel tube for exceptional load-bearing capacity and durability.

Key Features

Compatible with standard Boomer, ROC, and Mustang drilling rigs
Ideal for difficult or unstable ground conditions
High installation efficiency - drilling, placing, and grouting in single operation
Self-drilling system eliminates need for cased borehole
Simultaneous drilling and grouting capability
Easy installation in all directions, including upward drilling
Suitable for limited space, low height, and hard-to-reach areas
Simple post-grouting system
Hot-dipped galvanized finish for corrosion protection

Applications in Tunneling & Ground Engineering

Application	Description
Radial bolting	Ground reinforcement around tunnel perimeter
Slope stabilization	Preventing landslides and slope failures
Forepoling	Advance support ahead of tunnel face
Micro injection pile	Small-diameter grouted piles for foundation support
Face stabilization	Securing tunnel face during excavation
Temporary support anchor	Short-term ground retention during construction
Portal preparation	Stabilizing tunnel portals before excavation
Soil nailing	Reinforcing existing slopes or excavations

Installation Procedure

Step 1 - Drilling

Connect alloy drill bit to anchor rod end. Connect drill sleeve and shank adapter to other end, then attach to drilling rig. Start drilling while injecting cooling water. Use coupling sleeve to extend anchor rod length as needed.

Step 2 - Hole Preparation

Remove drill rig. Insert grouting stopper and push to bottom of hole. For excessive rock grouting tension or highly fractured rock, use anchor agent to seal the hole.

Step 3 - Grouting Connection

Connect quick grouting coupling to anchor rod end, and connect other end to grouting machine.

Step 4 - Grouting

Begin grouting and stop when grout fills completely and reaches design value. Grouting pressure determined by design parameters and machine performance.

Cement/Sand Ratio (reference): 1:0 to 1:1

Water/Cement Ratio (reference): 0.45:1 to 0.5:1

Step 5 - Final Fixing

Install anchor plate and tighten nuts to complete installation.
