Tunnel de Revenez

SPIDER^® S3-130 protecting the railway line between Martigny, Switzerland, and Chamonix, France, together with the road to Finhaut, providing a perfect big block stabilization

Portal of the Tunnel de Revenez - on the left a big amount of scree removed from the railway line

The site before installation with its steep rock slope directly next to the railway line

Situation before the stabilization with SPIDER^® S3-130 - large loose blocks are endangering the infrastructure below

Overview before protection measures were implemented

High tensile SPIDER^® S3-130 net was unrolled on the slope before drilling works began. Thus during the top-down drilling the safety of the construction crew was ensured

To provide optimal blocks stabilization and SPIDER^® S3-130 net pre-tensioning, GEWI 32 nails were installed in the dells - where possible

Detail of the slope stabilization SPIDER^® S3-130 net fixed with GEWI 32 nails, border rope and system spike plate P33/40

At the crest above the stabilized slope, an extra RXE-500 rockfall barrier line was installed to provide extra protection against rockfalls from upper areas

The RXE-500 rockfall barrier installed directly above the stabilized slope

SPIDER^® S3-130 protecting the railway line and the road, providing perfect stabilzation of the large blocks
