Tunnel drilling machine Debohra celebrates the breakthrough for the U2 route!

The tunnel boring machine "Debohra" recently made a significant breakthrough for the new U2 route in Vienna. After nine months of hard work, the impressive machine dug two kilometers through the underground. The breakthrough took place on Augustinplatz in the seventh district, where the Viennese lines are now celebrating the progress of the subway extension. "Debohra" has reached the greatest length, as the managing director of the Wiener Linien, Gudrun Senk, announced. " Meinverzirk reports that the starting point of the passages on Matzleinsdorf was located on the border between the districts and favorites and Margareten.

On a total route of around four kilometers, "Debohra" will in future connect a total of four new stations. These are the U2xs Matzleinsdorfer Platz, U2 Reinprechtsdorfer Straße, U2xu4 Pilgramgasse and U2xu3 NeubaGasse. An interesting tradition is also cultivated in the mining: tunneling machines often get female names to bring happiness and to honor Saint Barbara. The Viennese chose the name "Debohra" in an online voting, with almost half of the voices in this name. Over 18,000 people took part in this voting, according to the motto "There is something" for the new subway line! Wiener Linien is composed.

the further course

Currently "Debohra" is positioned so that she works back towards Matzleinsdorfer Platz. Your next goal is to create a second tube for the U2 that will enable traffic in both directions. The last section of the new U2 tunnel, which will lead to the town hall, is excavated with excavators. The complete commissioning of the new U2 section is planned for 2030, which means a significant improvement in the connection for the approximately 15,000 people who live in the catchment area.

"Debohra" made a first breakthrough on Pilgramgasse in March, where the U2 will cross the U4 in the future. These progress show how important the expansion of the subway network is for Vienna and how the city continues to invest in the infrastructure. The individual segments of the machine were delivered directly to the construction site at Matzleinsdorfer Platz, where they were assembled and transported at a depth of 30 meters. The Schneidrad of "Debohra" has almost seven meters in diameter and is most of the machine-a real monster that works precisely and strongly underground. In his work, Cudmani documents the development of tunnel construction and tunneling machines, which gives an interesting insight into the technology behind such projects.
