Structural fire protection
Industry and OEM
Impact and damage
Because of the spatial limitations of a tunnel, tunnel fires render all escape, rescue and repair measures rather difficult, and are hence regarded to be the greatest risk to people, vehicles and the tunnel structure itself. High-performance fire-protection systems are therefore required to satisfy the demanding structural fire-protection requirements in tunnels. These measures reduce the risk of injury, and avoid severe fire damage to the tunnel structure and, consequently, long closures (leading to a loss of income for tunnel operators and neighboring regions).
Requirements for structural fireprotection systems are assessed on a project-specific basis using internationally recognised time-temperature curves (see page 6-7).
The structural fire-protection system ensures that, in the event of a fire:
Aestuver® fire-protection boards are used as independently fixed or directly concreted (Permanent Formwork) cladding in underground transport systems and protects the entire concrete structure and reinforcement from harmful temperatures. The clear benefits of Aestuver® fire-protection boards for tunnel operators and transport agencies include the following:
Cement-bonded tunnel fire protection panels Aestuver® T and Aestuver® Tx meet the highest safety requirements in underground traffic facilities. An important advantage is that the overall economic damage in the event of a fire is considerably lower than with uncovered concrete.
This is documented in the STUVA study about a profitability and follow-up cost analysis for the use of fire protection panels in tunnels from 2019.
