Technical Q&A
What is the maximum speed of the tunnel 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.
How to improve the working efficiency of tunnel cleaning vehicles?
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
How to ensure the safety of tunnel cleaning vehicles during operation?
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
