Initial situation
Former Quarry along the road N27, next to Erpeldange-Michelau
Close to the location Michelau (Luxemburg) on a steep, north exposed rock slope in a former limestone quarry, a rockfall incident with a volume of around 1000 m³ ocurred. The cliff spreads along a distance of around 300 meters and reaches a maximum height of 30 meters. It is located on an eroding bank of the river Sure.
As an emergency measure the road was rerouted to the other side of the river, via a provisional bridge. Since further examiniation of the cliff showed a constant risk to the remaining road, rockfall protection measures had to be taken.
Description
The rockfall protection measures installed along the cliff are two RXI-500 Barriers:
- Barrier RXI 500, Length 78 m, Height 5.5 m
- Barrier RXI 500, Length 64 m, Height 7.0 m
The rockfall protection measures installed on the dam towards the road are:
- 1.7 m² TECCO G65/3 to stabilize the dam itself and atop
- A small GBE-100 AR rockfall barrier, Length 70 m, Height 2.0 m
