Es beginnt mit einer ebenen Betonfläche
A wildlife crossing over the upcoming Koralm railway is being built, using a new construction technique developed by TU Wien. Traditional support structures are replaced by an air cushion. The shell construction methods which are usually used to build bridges and domes generally rely on expensive support structures. However, a team of engineers from TU Wien have now developed a new technique that is not only cheaper, but also makes more much efficient use of resources. Instead of using a support structure, an air cushion is inserted underneath the concrete and gradually inflated during the construction process. The first major tests were carried out three years ago at a TU Wien test site, but now the new method has been used in a real-life project for the very first time by the Austrian Federal Railways (ÖBB-Infrastruktur AG). With the help of TU Wien, the Austrian railway network operator has successfully used the technique to build a wildlife crossing over a new section of track on the Koralm railway.
