Konrad Aurin, Department of Tunnels, Täby Brandskyddsteknik

People that travel through or stay in tunnels and other subterranean locations have the right to an extra high level of preventive and active fire protection.
TBT:s Tunnel department has solid experience within this area, and with ongoing close cooperation with tunnel and community builders, researchers and consultants, manufacturers of materials and equipment and systems for efficient fire protection.
Our services in this area includes inventory, planning, execution and coordination of fire protection as well as other functional and esthetic aspects in conjunction with tunnel building.

THE STOCKHOLM CITY TUNNEL

Stockholm’s City Line is a 6 km long railway tunnel now being built underneath the Swedish capital’s inner city. After several years of planning the project was initiated in 2009, aiming at inauguration in 2016.
In addition to the dual main railway tracks, the project also includes one service tunnel, two safety tunnels and other facilities.
Early in 2014, the main construction company assigned Täby Brandskyddsteknik to look over the total project from a fire protection point of view, and eliminate any potential fire hazards. This review resulted in some rather extensive changes to the original plans, not just to ensure reliable fire protection but also to eliminate unnecessary costs.

About fire protection in tunnels

In a fire situation the structural concrete in the tunnel’s ceiling and walls are heated up very quickly. With a few minutes the temperature inside the concrete can reach nearly 1200oC.
The moisture nearest to the surface evaporates directly, the rest moves further inwards, and a major part of it accumulates around the steel reinforcement . As the moisture expands, the concrete spall with great force, and in many cases the tunnel collapses.
The most important aspect of fire protection in tunnels, by far, is to prevent such a course of events. And this is the very area where Täby Brandskyddsteknik has world-leading competence.
