Protecţia împotriva căderilor de pietre - Balmi-Tschuggen 2015

View from the protected road of two barriers: On the line 1.1 (2000 kJ, H = 6 m) installed on the bare rock face and on the line 1.7 (2000 kJ, H = 5 m) installed on a very steep and high slope.

Technical pre-approval of the line 1.2 (1500 kJ, H = 6 m).

In anticipation of small diameter falling rocks on the line 1.2 (1500 kJ, H = 6 m), a very fine secondary mesh was installed (25 mm x 25 mm) along with the barrier.

The very same day of installation acceptance by the customer (ASTRA - Federal Roads Office), several blocks were successfully retained by the line 1.9 (2000 kJ H = 5 m, adapted to withstand snow pressure).

View of the lines 1.9, 2.0 and 2.2 (all 2000 kJ, H = 5 or 6 m). Due to their location, they are also adapted to withstand snow pressure.

Situația inițială

The existing rockfall barriers above national highway A8 over the Brünig Pass were greatly weakened after years of prevalent heavy snowfalls and had to be replaced. Therefore, the Swiss Federal Roads Office (ASTRA) in 2014 invited IMPULS AG to consult the new project (installed by Gasser Felstechnik AG).

Descriere

A total of eleven lines* with energy absorption capacities between 1,000 and 2,000 kJ were installed:

1000 kJ: height = 6 m, length = 30 m

1500 kJ: height = 6 m, length = 56 m

2000 kJ: height = 5 m and 6 m, length = 122 m

In addition, five lines were dimensioned for rockfall as well as for snow slide so that multi-hazard barriers  were installed:


2000
kJ: height = 5 m and 6 m, length = 139 m

* The RXI barriers used are now superseded by the RXE barriers.
