Global Application Scenarios

1. Infrastructure Auxiliary Support

• Tunnel lining fixing (Vietnam, Indonesia): Adapts to wet tunnel environments, no need for hydraulic tools.
• Building facade installation (Europe, North America): Securely anchors curtain walls and external fixtures.
• Guardrail & sign anchoring (North America, Australia): Fast installation for highway and coastal protection projects.

2. Mining Auxiliary Support

• Mine ventilation duct fixing (South Africa, Australia): Lightweight and easy to operate in narrow mine roadways.
• Equipment base anchoring (China, Canada): Stable support for mining auxiliary equipment in high-vibration environments.

3. Water Conservancy & Coastal Projects

• Coastal revetment auxiliary support (Indonesia, Brazil): Corrosion-resistant options for salt spray environments.
• Irrigation channel reinforcement (India, Middle East): Adapts to dry or wet soil conditions with water-activated expansion.

4. Civil & Landscape Engineering

• Temporary support for deep foundation pits (Middle East, Europe): Fast deployment for excavation safety.
• Landscape engineering anchoring (Europe, Southeast Asia): Secures retaining walls, flower beds, and outdoor structures.

Step-by-Step Installation Guide (with Regional Adaptation)

1. Pre-Installation Preparation

• Tools Required: Electric drill (14-22mm bit, matching anchor diameter), measuring tape, level, water spray bottle (for dry environments), wrench (for minor adjustment—no hydraulic tools needed).
• Material Preparation: Water-activated expansion anchors, matching nuts (if required), and cleaning tools (compressed air or brush).
• On-Site Check: Conduct geological surveys to confirm rock/soil conditions; mark drilling positions (spacing: 200-300mm, hole depth 10-15mm longer than anchor length).

2. Standard Installation Steps

1. Precise Marking: Mark drilling positions according to engineering drawings, ensuring alignment with load-bearing requirements.
2. Drilling: Drill holes 2-3mm larger than the anchor diameter (e.g., 16mm hole for 14mm anchor). Use spiral bits for soil/soft rock and diamond bits for hard rock.
3. Hole Cleaning: Remove dust and loose particles with compressed air or a brush—clean holes ensure optimal polymer adhesion.
4. Moisture Preparation: For dry environments (e.g., Middle East deserts), spray 2-3ml water into the hole; humid/coastal regions require no additional water.
5. Anchor Insertion: Insert the anchor into the hole, ensuring the polymer sleeve is fully embedded—avoid hammering to prevent sleeve damage.
6. Final Adjustment: Use a wrench to slightly tighten the nut (torque ≤30 N·m) for flush alignment with the surface.
7. Expansion Curing: Wait 5-10 minutes for polymer expansion (extend to 15 minutes in low temperatures); avoid loading the anchor during curing.

3. Regional-Specific Precautions

• Dry/Desert Regions (Middle East, North Africa): Spray 3-5ml water into the hole; store anchors in shaded areas to prevent polymer aging.
• High-Temperature Mines (South Africa): Use heat-resistant polymer sleeves; install in shaded spots and spray cool water to avoid overheating.
• Humid/Coastal Regions (Southeast Asia, Australia): Select epoxy-coated anchors for salt spray resistance; no additional water needed for activation.
• Permafrost Regions (Siberia, Canada): Pre-heat holes to 5-10℃ with a portable heater; use low-temperature polymer anchors and spray warm water (15-20℃) to activate expansion.

Quality Control

1. Raw material inspection: Chemical composition test for steel cores and polymer expansion rate verification.
2. Production inspection: Dimensional accuracy measurement, shear resistance testing, and expansion performance verification (≥300% expansion in 10 minutes).
3. Finished product test: Salt spray corrosion resistance test (≥500 hours) and breaking load test (minimum 110 kN for PM12).
4. Packaging inspection: Moisture-proof and anti-collision checks to prevent premature expansion during shipping.
