📋 Tender Overview
Construction contractors have reached a new milestone on the route of the second track! The Tinjan tunnel (T4), which is almost two kilometers long, is excavated and supported. It is the fourth longest tunnel on the route of the second track.
The Tinjan tunnel is a single-tube tunnel and, with its length of 1,949 meters, belongs to the medium-long tunnels. It also has two exit tunnel tubes. Work on the tunnel started at the beginning of June 2022, and mostly the tunnel runs in an area where there are no inhabited buildings in the influence zone of the tunnel construction.
Until now, the tunnels Mlinarji (T7), Škofije (T8) and Osp (T3) have already been excavated on the route of the second track. Excavation is followed by the production phase of the inner lining of the tunnel. This has already been completed in the last two tunnels on the route from Diva?a to Koper.
Like all tunnels on the route of the second track, a construction method called NATM (New Austrian Method) was used in the excavation. Already during the excavation and support of the Tinjan tunnel, work on the secondary lining system began in the tunnel. These works will now continue.
