Resin anchor rod anchoring agent

Product Overview (within 150 words)

ChangQi resin bolt anchoring agent is a chemical anchoring system specifically designed for tunnel and mine support, achieving rapid curing and high bonding strength through a two-component resin capsule. It is suitable for geotechnical reinforcement in complex geological conditions, such as tunnel linings, slope stabilization, and mine roadway support. With controllable gel time (10-200 seconds), compressive strength exceeding 80MPa, and customization options for cold regions, it is a "fast and reliable" anchoring solution for geotechnical engineering.

Detailed Product Introduction (500+ words)

ChangQi Resin Bolt Anchoring Chemical Capsule Agent is an innovative anchoring material for geotechnical engineering in tunnels, mines, etc. It is composed of unsaturated polyester resin, marble powder, accelerators, and other components mixed in specific proportions, packaged in a two-component roll (encapsulated in special polyester film). It features rapid room-temperature curing, high bonding strength, and excellent durability, making it widely applicable in tunnel linings, slope support, mine roadway reinforcement, and other fields.

1. Technical Principles and Core Advantages

The working principle of resin bolts involves a chemical reaction between the two-component resin, tightly bonding the bolt to the borehole wall to form a high-strength anchoring system. ChangQi resin bolts offer the following advantages:

• Precision and Low Insertion Force: Repeatable strength characteristics allow precise anchoring parameter design, reducing installation resistance, suitable for handheld or mechanical equipment.
• High Strength and Adaptability: Customizable formulations for different geological conditions (e.g., fractured rock layers, soft soil), enabling easy penetration even with handheld devices.
• Durability and Corrosion Resistance: The resin layer effectively protects the bolt from acidic water, seawater, or groundwater corrosion while isolating air to prevent further rock deterioration.
• Safety and Reliability: Millions of resin bolts are used annually in critical projects like mines and tunnels (e.g., permanent rock reinforcement), proving stability in high-risk scenarios.
• Rapid Curing and Efficient Construction: Controllable gel time (10-200 seconds), with loading completed within minutes, significantly shortening construction periods—ideal for emergency tunnel bolt and slope reinforcement.
• Stress-Free and Vibration Resistance: No internal stress on rock or concrete, unaffected by vibrations (e.g., nearby blasting), eliminating the need for secondary tensioning.

2. Product Parameter Table: Standardization and Customization

ChangQi resin bolt anchoring agent offers multiple standard models and supports customization (e.g., cold-region formulations). Key specifications include:

3. Application Scenarios: Comprehensive Geotechnical Engineering Needs

ChangQi resin bolt anchoring agent is widely applicable, including:

• Tunnel Engineering: Initial and permanent support for tunnel linings, especially in weak surrounding rock or fractured zones, where rapid curing shortens construction cycles.
• Mine Support: Roof reinforcement and wall support for mine roadways, addressing rock deformation under mining pressure to enhance safety.
• Slope Engineering: Stabilization of highway and railway slopes, preventing landslides and collapses, particularly effective in rainy or earthquake-prone areas.
• Hydraulic Engineering: Reinforcement of dam slopes and channels, resisting water erosion and seepage pressure to extend project lifespans.
• Building Foundations: Reinforcement of building foundations, such as pile and footing anchoring, improving stability.

4. Customization Services: Meeting Special Requirements

ChangQi resin bolt anchoring agent supports deep customization, including:

• Size Customization: Length (20cm-200cm) and diameter (adjusted based on borehole size) can be produced per customer needs.
• Performance Customization: For cold regions (delayed curing in low temperatures), formulations can be adjusted to ensure effectiveness.
• Color Customization: Available in yellow, red, blue, white, etc., for easy identification and management on-site.

Conclusion

ChangQi resin bolt anchoring agent, with its high reliability, rapid construction, and adaptability, is the preferred anchoring material for geotechnical engineering in tunnels, mines, etc. Whether for standard projects or special scenarios, ChangQi offers customized solutions to enhance both safety and efficiency.
