Alpenquerende Tunnel: Materialbewirtschaftung und Betontechnologie beim Lötschberg‐Basistunnel

Abstract: Beim Bau des 34, 6 km langen Lötschberg‐Basistunnels werden 16 Mio. to Material ausgebrochen, davon 10 Mio. to im Südabschnitt und 6 Mio. to im Nordabschnitt. Für die Materialbewirtschaftung wurde ein umfassendes globales Konzept erarbeitet. In dessen Mittelpunkt steht die Aufbereitung von Ausbruchmaterial zu Betonzuschlagstoffen, die für die Herstellung des im Projekt verbauten Betons benötigt werden. Von besonderem Interesse ist der Umstand, dass aus teilweise Alkaliaggregat‐reaktiven Betonzuschlagstoffen ei… Show more

“…Together with the Gotthard Base tunnel, the two-tube 34.6 km railway Lötschberg Base tunnel is part of the New Rail Link Through the Alps (NRLA) route and was constructed at north and south lots providing the first high-speed connection from Frutigen to Raron in Switzerland. Its opening in 2007 preceded the excavation of 16 million tons of rock and soil, whereas 10 million were associated to the south and 6 million to the north portal (Teuscher et al, 2007). The north tunnel was solely excavated by conventional methods (drill and blast), while the south tunnel portal was partly excavated by a hard-rock TBM as well as drill and blast in different geological units of sandstone, siliceous limestone, lithotamnian limestone, granodiorite, gneiss, granite and amphibolite (Fachgruppe für Untertagebau (FGU), 2016; Teuscher et al, 2007).…”

Excavated material was classified into three application classes ranging from concrete to sand-gravel production (K1), embankment and backfilling (K2) and disposal (K3).…”

“…Switzerland has played a leading role in the recycling of spoil from tunnels at the Lötschberg [14] and Gotthard Base tunnels [9]. The fact that the Austrian construction industry is also active in the field is demonstrated by numerous efforts on current projects like the Koralm Tunnel [5], the Brenner Base Tunnel [1] or the S1 Tunnel DanubeLobau [13].…”

“…Die Schweiz hat mit dem Lötschberg- [14] und dem Gotthard-Basistunnel [9] gezeigt, dass sie im Bereich der Verwertung von Ausbruchmaterial bei Verkehrstunnelbauten eine Vorreiterrolle einnimmt. Dass die Thematik auch die österreichische Bauindustrie beschäftigt, zeigen zahlreiche Anstrengungen bei aktuellen Projekten wie etwa beim Koralmtunnel [5], dem Brenner-Basistunnel [1] oder dem S1 Tunnel Donau-Lobau [13].…”
