Situation

The old bridge over the Reno di Lei was hit by a rockfall. As part of the restoration work, a suitable measure was sought for protecting the old bridge – and the abutment of the new bridge situated above it – from falling rock. For reasons of aesthetics and to preserve the surrounding countryside, it was not possible to construct a rockfall protection roof above the portal.

Description

The solution presented by Geobrugg envisioned a RXI-200 rockfall barrier (2000 kJ) acting as a deflector, with the system being aligned almost vertically above the abutment. In contrast to a conventional rockfall barrier, three central suspension cables were installed in addition to the upper and lower suspension cables in order to reduce net deflection and allow rocks to be diverted.
