Project name: Tunnel Leutenbach
Project date: 2008/09
Products: 52 000 m² AGRUFLEX tunnel liner 3.2 mm, fleece-backed and coextruded, VLDPE tunnel liner, 7 800 m water stop profile SAA 500/6
The expansion of the federal road B14 required the construction of a tunnel to relieve the city of Leutenbach from excessive traffic. 660m of the two parallel tunnel tubes, with a total length of 1 080 m were made by blast construction. Moreover, three rescue shafts were excavated for security reasons - to provide sufficient escape routes.
The AGRU Easy Fix system, combined with hot air mounting, was used to seal the arch to achieve highest performance. Geotextile-backed VLDPE tunnel liner and a textile that is fixed to the shotcrete were installed.
By means of an automatic process, both textiles were thermally bound by using a hot air bar mounted onto the scaffolding. Furthermore, rollers ensured the pressure necessary for joining.
