情况

The road has been protected for years by two rockfall barriers RXI-500. At this location exists a very high rockfall activity. For these reasons, the fence's material must be removed regularly, which requires regular inspections of the fence. Not only small events can fill the barrier over time. Also, large rockfall events can occur. The rockfall barriers must then be emptied immediately.

描述

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

UPDATE: In December 2023, the GUARD demonstrated its positive performance at barrier 1 in Michelau. Two dynamic impacts with 33 g-force and 39 g-force were detected there. The stone blocks rolled down the steep slope from a height of 80 meters. The responsible authorities were informed immediately and were thus able to check the condition of the barriers promptly and plan maintenance work. Despite the impact, the barrier was still functional, and the clearance work and repair of the secondary mesh were planned for spring 2024.
