Situation

Heavy rain cause a 40'000 cubic metre slip to completely close SH6 for several weeks in September 2013. Once cleared the road remained closed at night due to the continued high risk of rockfall from over 250m up the slip face. Some of the unstable rocks were larger than 20 foot shipping containers.

Description

Geovert were awarded the contract to design and buld a bespoke rockfall protection solution above the State Highway to actively control the frequent high energy rockfalls. The best solution for the site was the construction of a 5m high 3000kJ and two 6m high 5000kJ Geobrugg attenuator barriers. The 3000kJ system was installed over 250m above the highway, the first of the 5000kJ system was installed 150m up and the final and largest barrier was installed around 50m above the road. The bottom rockfall attenuator was a massive structure with a 35t high tensile steel ROCCO ring net drape to control and channel the falling rocks and debris to the roadside for the maintenance crew to clear.
