METHOD FOR PRODUCING A TUBBING HAVING A THERMOPLASTIC SEALING LAYER |
| 摘要 |
A method is disclosed for producing a tubbing made of concrete for lining a tunnel, particularly a traffic tunnel, wherein the tubbing has a convexly curved outer surface and a concavely curved inner surface opposite the outer surface. The method can include: a) placing a membrane having a dispersion adhesive layer and a thermoplastic sealing layer onto the outer surface and further onto at least one of the sides of the outer side surfaces of the tubbing facing the outer surface, wherein the dispersion adhesive layer faces the tubbing; b) supplying heat, thus partially melting the dispersion adhesive layer; and c) cooling the dispersion adhesive layer, thus forming an adhesive bond between membrane and the tubbing. |

1. Method for producing a tubbing made of concrete for lining a tunnel, wherein the tubbing has a convexly curved outer surface and a concavely curved inner surface opposite the outer surface, the method comprising:
a) placing a membrane having a dispersion adhesion layer and a thermoplastic sealing layer onto the outer surface and further at least partially onto at least one, of the sides of the outer side surfaces of the tubbing facing the outer surface, wherein the dispersion adhesive layer faces the tubbing; b) supplying heat, to partially melt the dispersion adhesive layer; and c) cooling the dispersion adhesive layer, to form an adhesive bond between membrane and the tubbing. |
