Influences on construction fixings in tunnels Fire A fire inside a tunnel represents an enormous challenge for the material used. The fire load may be very high due to traffic passing through the tunnel. Temperatures may also rise to very high levels due to tight spaces in the tunnel. Fire fighting is extremely difficult. For this reason it is important for fastening material not to fail in case of fire before a certain time has passed. In general, the standard temperature curve according to

Construction fixings in tunnels
DIN 4102 is not sufficient for the structural design of exposed fastening material. The Würth anchors W-FAZ/HCR, W-FA/HCR M6, W-NA/HCR and W-VIZ/HCR have therefore been tested according to the time-temper ature profile of the “Additional technical terms of contract and guidelines for civil engineering works (ZTV-ING), part 5 Tunnel Construction” and thus comply with all requirements of fire protection in tunnels.
Fatique loading Trains and trucks passing through tunnels cause fatique loading on the construction fixings. In particular, this includes wind pressure and suction. Continuously repeating periodic loads on anchors may lead to fatigue failure of the fastener. This may already occur after approx. 10,000 load changes (e.g., in the case of 10 load changes per day, there will be more than 10,000 load changes within 3 years).
Therefore many of the applications in tunnels may be fixed with anchors approved for fatique loading. Only this prevents the failure. This also applies to dynamically loaded operational structures, such as jet ventila tors. The resin bonded anchor system W-VIZ dynamic is approved for fatique loading is generally used for such applications.
Corrosion Environmental conditions inside road tunnels regularly represent increased challenges for fasteners and their corrosion resistance. This includes humidity, de-icing salts and exhaust gases. According to the stainless steel approval Z-30.3-6, a steel quality in accordance with corrosion resistance class V is required in road tunnels due to the high pollution caused by sulfur dioxide (SO2). This class includes highly corrosion-resistant steel (HCR steel), which is also required according to “ZTV-ING, part 5 Tunnel
Construction”. A4 stainless steel must not be used in road tunnels since this material may fail due to invisible stress crack corrosion. With its product range of anchors made of highly corrosion resistant (HCR) steel and all other popular steel qualities, Würth covers all applications in tunnels. On the following pages you will find a selection of fastening solu tions made of HCR steel.
