According to the invention, this is achieved by the insulation consisting of a phenolic resin foam. Preferably, it is a melamine resin foam.

in der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Mit 1 ist der Gebirgsausbrueh bezeichnet. Am Gebirgsausbruch ist mittels Ankern 2 ein Drahtnetz 3 befestigt« Das Drahtnetz 3 bildet eine Steinschiagsic-herung. Zur Tunnelinnenseite ist Vor dem Drahtnetz 3 eine Abdichtung 4 aus Kunststoff vorgesehen. Die Abdichtung 4 besteht aus einzelnen miteinander Verschweißten Abdichtungsbahneni Auf der Kunststoffabdichtung 4 sind Meiaminharzschaumplatten 5 als Wärmeisolierung verlegt* ate in Figur 2 In einer SffiZSTSfisiCfit uäryeSucllu 5&Iacgr;&idigr;&iacgr;&uacgr; An embodiment of the invention is shown in the drawing.
