Fire-extinguishing pipes at the Unzmarkt underground line, Styria

ASFINAG has built a new tunnel on the S 36, the Murtal expressway, in the area of the municipality of Unzmarkt in Styria, the underground line Unzmarkt. In order to equip the new route with appropriate safety devices, fire-extinguishing pipes were installed by STRABAG. Ductile iron pipes from Tiroler Rohre GmbH were used over a length of 1.000 meters. The decision in favor of the pipes from Tyrol with a nominal diameter of DN 150 was made on the basis of the tried-and-tested push and pull-proof connection system VRS-T. A special feature of the execution of this project is the use of the welding bead machine designed by the application technology departement of Tiroler Rohre GmbH. With this device, the construction company STRABAG was able to apply a weld bead to the cut pipes on site at the construction site. This resulted in a consistently positive connection. In addition to the work on the underground line in Unzmarkt, the existing line between St. Georgen ob Judenburg and Scheifling is also being renovated, including bridges, railings, markings, water systems and the entire signage.

Safe water supply.
