FIELD: construction.SUBSTANCE: invention relates to a safety element for connection with a concrete element of a tunnel lining, a concrete element and a method to make the concrete element. The safety element for connection with the concrete element of the tunnel lining, which has a protective section made as capable of connection with at least one surface of the concrete element. The safety element is comprised of an artificial material, and on its inner side it has at least one connection element to create a retaining connection with the concrete element. The safety element comprises a bottom section and a wall section. The artificial material is an artificial material suitable for pressure casting. The safety element is solidly connected to a seal, at the same time the connection is gas impermeable and liquid-tight. The safety element is solidly connected to the connection element, at the same time the solid connection of the safety element with the seal and the connection element is made by means of pressure casting of the artificial material.EFFECT: objective of the invention is to propose the safety element of the tunnel lining or a related concrete element, by means of which high reliability of the protective tunnel lining is provided against liquids and gases.7 cl, 9 dwg |
