KEY PARAMETERS FOR RAILWAY MONITORING

Using a series of Tiltmeters or Tilt-beams, mounted on the sleepers, it is possible to obtain their rotations and longitudinal deformation, that represents the ground deformations.

The dynamic part of the monitoring is carried out with Deck sensors that allow you to monitor the dynamic displacement of the sleepers when the train passes.

With the use of Single Channel Nodes, it is possible to complete the monitoring system with all non-native wireless geotechnical sensors.

Cross level of the tracks The transversal level is defined as the transversal slope of the track expressed as the difference in height between the two rails. The use of the Tiltmeters, positioned on the sleeper, permits to get the measurement of the difference in elevation of the tracks using the tool and to monitor its trend over time. The twist is the algebraic difference between two transversal levels taken separately at a predefined distance, usually expressed as a gradient. The use of the Tiltmeters, positioned on the sleeper, allows to calculate this parameter. The twist is the most delicate thing for the stability of the vehicle-track coupling, it is often the case of a train derailment. Twist of the tracks Longitudinal deflection Tilt-beam of different lengths (1; 2; 3m), if placed in a chain, allows to calculate of the track's vertical displacement and reconstruct its deformation with a broken line. In this way, it is possible to obtain and visualize the exact vertical lowering of the tracks. Ballast void The contamination of the ballast from external materials, known as fouling, can compromise the integrity and drainage capacity of the ballast. The Deck sensor, installed on the sleepers, allows to monitor the dynamic oscillation amplitude of the sleeper as the train passes and to correlate its variation to the degradation of the ballast. Geotechnical monitoring With the Single Channel Nodes it is possible to complete the monitoring system with other geotechnical probes for ​monitor the ground displacement (settlement or lateral movement) and groundwater levels.
