Abstract (en)
[origin: WO2014111583A1] The invention relates to a method for producing a lining segment made of concrete for lining a tunnel, in particular a traffic tunnel. The lining segment (1) has a convexly curved exterior (2) and a concavely curved interior (3) opposite the exterior (2). The method consists of the following steps; of a) placing a membrane (4) having a hot-melt adhesive layer (5) and a thermoplastic barrier layer (6) on the exterior (2) and additionally on each lining segment outer surface (7, 8) face facing the exterior (2), said hot-melt adhesive layer (5) facing the lining segment (1); b) supplying heat while melting the hot-melt adhesive layer (5); and c) cooling the hot-melt adhesive layer (5) while forming an adhesive bond between the membrane (4) and the lining segment (1).
