AZA 1006 ROCK BOLT PULL OUT TEST APPARATUS

Description

The AZA 1006 Rock Bolt Pull Out Test Apparatus is a high-precision, field-grade testing instrument designed to evaluate the pull-out strength of rock bolts, anchor bars, and grouted tendons. Used widely in mining, tunneling, slope stabilization, and underground excavation projects, this apparatus ensures reliable safety assessment and quality control of anchoring systems embedded into rock masses.

As underground infrastructure continues to expand globally, ensuring that the rock bolts anchoring these structures are holding firm is more critical than ever. The AZA 1006 meets this challenge with portable, rugged construction, simple operation, and precise results, helping engineers and geotechnical teams verify the performance of rock supports directly in the field.

🔍 What is a Rock Bolt Pull Out Test?

The rock bolt pull out test simulates real-world tension forces on a rock anchor to assess its performance. The goal is to measure the maximum load a rock bolt can sustain before failure or significant deformation. This data is crucial in determining the bolt’s ability to support underground roofs, tunnel walls, or slope faces.

Key parameters assessed include:

• Tensile strength of the anchor

• Bonding efficiency between grout and bolt

• Rock mass compatibility

• Installation quality and workmanship

Testing is typically carried out in-situ on installed bolts, making portability and field ruggedness essential — and AZA 1006 delivers exactly that.

⚙️ Core Features of AZA 1006

• Hydraulic Load Application System: Equipped with a high-pressure hydraulic jack capable of applying up to 200 kN load, enabling tests on various bolt types.

• Digital or Analog Load Measurement: Depending on model, load is measured via precision pressure gauge or an integrated digital load cell with LCD display.

• Dial Gauge for Displacement Monitoring: Measures elongation or movement of the anchor under load to determine bolt behavior under stress.

• Universal Bolt Grips: Adapts to different bolt diameters (typically 12–25 mm), including threaded and smooth rods.

• Portable Carrying Case: Compact and robust for underground transport and rapid deployment in field conditions.

🏗️ Applications Across Industries

1. Mining Operations: To evaluate roof bolts in underground mines.

2. Tunneling Projects: Assess support elements in metro, highway, or rail tunnels.

3. Dam and Hydro Projects: Test anchors in penstocks or cavern walls.

4. Geotechnical Surveys: Ensure long-term slope stability and rock face retention.

5. Research and Academia: Used in universities and geotechnical institutes for training and development of rock mechanics.

🧾 Use Case Example

Imagine a tunnel construction site where 5-meter-long rock bolts are being installed for roof support. To ensure their reliability, field engineers use the AZA 1006 to apply a pull force of 150 kN to randomly selected bolts. The apparatus records load vs. displacement, and the results show strong adhesion with minimal elongation — confirming structural safety and reducing project risk.
