METHOD FOR PRODUCING A TUBBING HAVING A THERMOPLASTIC BARRIER LAYER

摘要

The invention relates fundamentally to a method for producing a tubbing made of concrete for lining a tunnel, particularly a traffic tunnel, wherein the tubbing (1) has a convexly curved outer surface (2) and a concavely curved inner surface (3) opposite the outer surface (2). The method comprises the steps: a) placing a membrane (4) having a dispersion adhesive layer (5) and a thermoplastic barrier layer (6) onto the outer surface (2) and additionally onto at least one of the sides of the outer side surfaces (7, 8) of the tubbing facing the outer surface (2), wherein the dispersion adhesive layer (5) faces the tubbing (1); b) supplying heat, thus melting the dispersion adhesive layer (5); and c) cooling the dispersion adhesive layer (5), thus forming an adhesive bond between the membrane (4) and the tubbing (1).
