Métro Lausanne, M2 Lot 1700 (Lot 1700)

Utvikling av Route de Berne-tunnelen

The Métro Lausanne, M2 Lot 1700 project focused on constructing the Route de Berne Tunnel between the Sallaz and Fourmi stations. The project scope included the development of Sallaz station with an open-air section and the fully underground Fourmi station, including its interior and access shafts. This was part of the larger Ouchy-Epalinges metro line which spans 6 km with 14 stops, 9 tunnels, and 5 bridges.

Ingeniørmetoder for sikker utgraving

For tunnel excavation, a machine with point attack was utilized, complemented by umbrella vault and horizontal jet-grouting techniques to consolidate the excavation profile and stabilize the attack front. Additionally, the rock walls were secured using an anchoring system, steel mats, and shotcrete to ensure structural integrity. These engineering measures were vital to address the project's complexity and ensure the safety and stability of the construction.

Fullført 2007, verdi 52 mCHF

The project commenced in March 2004 and was successfully completed by April 2007, with a construction volume valued at 52 million CHF. The costs, translated into various currencies, reflect the significant scale and investment required for this infrastructure project. The Métro Lausanne, M2 Lot 1700 not only enhanced public transportation in Lausanne but also demonstrated advanced engineering techniques in tunnel and underground station construction.
