Initial situation
National road no. 7 (DN7) is one of the most important routes through the Carpathian Mountains, with heavy traffic. The Olt River runs parallel to the DN7 with high mountains, directly next to the road. In winter and spring rockfalls occur regularly. Also with unstable slopes, torrents and avalanches the risk of accidents was high.
This project was originally developed with five concrete canopies for rockfall protection. Due to costs and other restrictions, a modern solution using high tensile steel wire was chosen. After further investigation, 23 dangerous areas were found and had to be protected using two types of protection systems: active and passive.
Description
GBE rockfall barriers were provided as a passive protection at the following sectors:
1. km 240+454 - 240+510
GBE-1000
- capacity: 1000 kJ
- height: 5 m
- length: 56 m
2. km 240+555 - 240+577
GBE-1000
- capacity: 1000 kJ
- height: 3 m
- length: 22 m
3. km 242+453 - 242+457 (as a debrisflow barrier)
VX-060
- height: 3 m
- length: 8 m
4. km 242+457 - 242+610
GBE-1000
- capacity: 1000 kJ
- height: 4 m
- length: 30 m and 36 m
5. km 242+859 - 242+940
GBE-1000
- capacity: 1000 kJ
- height: 4 m
- length: 30 m
6. km 243+099 - 243+179
GBE-1000
- capacity: 1000 kJ
- height: 4 m
