The load bearing beams in the first Tingstad tunnel are now insulated with Benarx Epoxy Panels. Chosen for its timesaving benefits, and for easy inspections under the insulation, the custom-made panels allowed for efficient installation, and the Swedish transport authority (Trafikverket) could reopen for traffic only days after it closed.
Responsible for the project in Beerenberg, Slavik Degtyarev, says the team is already preparing for the next phase, with installation of the next batch this summer.
”This is an exciting project for us that we hope can lead to similar projects within tunnel and infrastructure markets,” says Slavik Degtyarev in Beerenberg.
The Tingstad tunnel is a highway tunnel under the river Göta, connecting Hisingen with the mainland of Gothenburg. The tunnel is part of the E6 route linking Norway with south-west Sweden and has two parallel immersed tubes with three lanes of traffic in each tube. The tunnel has a high traffic load with approximately 125,000 vehicles per day.
Trafikverket is now reconditioning the tunnel’s construction to increase its life span, replacing most of the technical installations and taking several measures to reduce the environmental impact as well as increase safety and reduce the consequences of accidents (source: Trafikverket). Beerenberg´s direct client in this project is Peab AB, a construction and civil engineering company headquartered in Förslöv, Sweden.
The Swedish Transport Administration requires access to inspect the load bearing beams every year, which is accomplished by the solution from Beerenberg. “So far, the customer is positively impressed with the results, adds Degtyarev.
