Innovation Highlights
1.Integrates arch erection, anchor hole drilling, automatic anchor replacement, automatic anchor feeding, prestress application, and grouting into one unit, equipped with plateau-specific components to withstand harsh environments and reliably handle high-altitude construction.
2.Supports dual operation systems—main cab and remote control—with bidirectional travel for rapid entry and exit, improving response efficiency and ensuring personnel safety.
3.Designed for snow-covered plateau railways with a compact cross-section, an overall vehicle width of 2.7 meters, a more streamlined structure, excellent passability, and flexible tunnel maneuvering without spatial constraints.
4.Integrates intelligent control systems and data acquisition technology to achieve automated, visualized, and data-driven construction processes. From single-machine intelligence to construction collaboration: future informatization will extend beyond individual equipment to the entire tunneling face management system, enabling data sharing and intelligent process coordination.
Construction Advantages
Compared with traditional manual construction
1.Workforce reduced by 70% (traditional arch erection requires 8-10 workers, anchor drilling 6-7 workers, and grouting 2 workers; now only 3 operators, 2 welders, and 1 auxiliary worker are needed);
2.Daily construction progress increased by 2.5 times. (Traditional manual arch erection takes no less than 3 hours, while the arch-anchor-grouting combined operation trolley completes arch erection in 45-50 minutes.);
3.Remote control operation achieves man-machine separation, reducing the risk of falls from height and mechanical injury by 90%.
Cost Advantages
Compared with large-machine construction (arch erection trolley + anchor drilling trolley + grouting pump)
1.No equipment withdrawal required, process transition time reduced by 2 hours per cycle, and daily construction progress increased by 15% (based on a single cycle time of 12 hours, the arch-anchor-grouting combined operation trolley completes a single cycle in 10 hours);
2.One piece of equipment replaces three, reducing equipment procurement/maintenance costs by over 1 million RMB.
The arch-anchor-grouting combined operation trolley not only redefines the limits of tunnel construction efficiency but also delivers comprehensive benefits of over 2 million RMB saved per kilometer through three major breakthroughs: "functional integration, intelligent operation, and intrinsic safety."
