Abstract
The invention relates to a protective element (20) for connecting to a concrete element (10) of a tunnel lining, to the concrete element (10) and to the method for producing the concrete element (10). It is an object of the invention to provide a protective element (20) for a tunnel lining, or the associated concrete element, which ensures that the protective casing of the tunnel lining is better safeguarded against corrosive gases or liquids. The solution of the invention provides that the protective element (20) is produced from an injection-moldable plastics material, that a protective portion (21, 22, 23) is connected in a single piece to a seal (30), wherein the connection is gas-tight and liquid-tight, that the protective portion (21, 22, 23) is connected in a single piece to a connecting element (24, 25, 26, 27, 28), and that the single-piece connection is produced by injection molding of the plastics material.
