Comprehensive inspection technology for track bed, subgrade, and ballast health using radar wave analysis.
1. Infrastructure hazard detection; 2. Detection of roadbed/subgrade diseases; 3. Fine evaluation of dirt and stains on the roadbed; 4. Macroscopic evaluation of dirt and stains on the roadbed; 5. Evaluation of the screening effect of roadbed cleaning; 6. Flatness testing of roadbed; 7. Identification of line characteristic equipment; 8. Tunnel Infrastructure Risks: Identify deep crushing, water-rich areas, voids, fractures, and subsidence; 9. Subgrade defects: Detect voids, settlement, and fragmentation; 10. Ballast bed contamination: Detect contaminants distribution, slurry boiling, and mud overflow; 11. Evaluation of large machine cleaning effectiveness; 12. Detection of ballast deficiency; 13. Established substantial experimental data bank (Shuohuang & Shanghai Railway Bureau); 14. Assistance decision-making and screening quality evaluation system; 15. Customized development of integrated GPR equipment for heavy-haul railway structures; 16. Implementation of 'condition-based repair' to save staff costs.
