Monitoring solution Geobrugg GUARD

Nine GUARDS for Luxembourg

28 Январь 2021

At the Carrière de Michelau exists a very high rockfall activity. The fence must be emptied regularly, which requires regular inspections of the two rockfall barriers. Not only small events can fill the barrier over time. Also, large rockfall events are possible. Then, the rockfall barriers must be emptied immediately.

To guarantee constant monitoring, nine Geobrugg GUARD devices were installed on the two fences. Installation and initial start-up were carried out independently by the customer.

With an acceleration sensor, larger rock impacts can be detected. The force measurement measures the slow filling of the fence. Furthermore, a corrosion sensor records the corrosion at this specific location, classifies it, and calculates the material service life.
