Embankment Monitoring: Hamm Railway




Challenge


The Dortmund to Münster railway line is one of Germany’s major train lines. During the end of 2018 a major fissure appeared along a 100m stretch of embankment, which ran parallel to the rail line. There was much concern and it was deemed necessary to deploy an emergency monitoring system to investigate further, eliminate potential risk and prevent any interference with the busy train line.
Due to Senceive’s pedigree in providing monitoring solutions for both slopes and track bed within the rail industry throughout Europe and beyond, Deutsche Bahn selected Senceive’s FlatMesh® system to monitor at-risk areas once the fissure had been filled in. This smart wireless system can be easily deployed in a matter of hours and allows the rail maintainer to see the relationship between slope and track.


Solution


To better understand and manage the impact of any potential slope movement to the track, Senceive sent an emergency track monitoring kit, consisting of 34 triaxial tilt sensors and a FlatMesh® gateway to measure sub-mm movements, which can be deployed in a matter of minutes if required. For the main investigation 3km embankment were monitored using a total of 233 stake-mounted triaxial tilt nodes, arranged in two offset rows at approx. 25m intervals. A FlatMesh® camera was also deployed to give clear still shots 24/7 of the main area that had the filled in fissure. This would be triggered upon significant movement.
The wireless sensors were all able to communicate with 7 solar powered gateways, which then transmitted secure data to the WebMonitor visualisation software, which can then be accessed online by registered users.


Outcome


During the late winter period, up to 9mm of movement was detected by multiple sensor nodes in the at-risk area during a one-week period, before returning back to the baseline. The FlatMesh® camera images could easily be accessed remotely and clearly showed that the area experienced snow during this time, which indicates that the movement was caused by extreme variations in temperature causing the ground to contract/expand.
This precise data and accompanying visuals corroborate the hypothesis that the fissure, and original movement that caused it, was due to de-vegetation of a local field which impacted the soil moisture levels near the rail line. This was then further influenced and exacerbated by seasonal changes such as the snow in winter. The exceptional battery life of the nodes, of 12-15 years, offers the flexibility for the monitoring duration to be extended to further investigate the seasonal impact on the slope movement and the emergency track bed monitoring kit is on hand in the event of movement relating to slippage which might impact the rail line.
