RTJ002 Metro Rail Tunnel Designed For Cleaning Vehicle

• Maximum operating speed during cleaning operations: 5–10 km/h, which ensures stable and thorough cleaning performance across tunnel walls, ceilings and floors.
• Maximum transfer speed between job sites (non-cleaning mode): 80 km/h, compliant with standard railway line operation regulations, enabling efficient and flexible deployment between different tunnel sections or maintenance depots.

Efficiency improvement of tunnel cleaning vehicles relies on integrated optimization:

• Adopting stepless speed regulation and fully automatic operation to ensure continuity
• Upgrading water supply, spraying, brushing, and sewage recovery systems to reduce repeated passes
• Optimizing vehicle maneuverability and multi-degree-of-freedom cleaning mechanisms for full coverage in one pass
• Strengthening on-site logistical support and route planning to shorten auxiliary time
• Applying intelligent control and real-time monitoring to reduce manual intervention and unexpected downtime
• Coordination with maintenance window plans also ensures efficient use of available operation time

The safety of tunnel cleaning vehicles is ensured through a combination of inherent safety design, standardized operation, and emergency preparedness:

• The vehicle is equipped with anti-collision sensors, emergency brakes, safety interlocks, and explosion-proof electrical systems
• Pre-operation inspections, strict traffic control, and qualified personnel are enforced on-site
• Real-time monitoring of the environment and operation status
• Clear emergency plans and regular drills further guarantee safe operation within the approved maintenance window
