<p>The tunnel has a compressible explosion protective layer (2) separated by a thin surface refined or locked layer. The layer (2) is arranged on or directly adjacent to an inner side of a carrying bowl (1) for accommodation of explosion forces. The forces are framed from segments, and a thin intermediate layer is fastened to the bowl by a connection unit. The thin layer is subsequently attached as a continuous sprayed-on or foaming layer. The layer (2) has a characteristic and is compressed with a static pressure of 1000 bar around more than 5 percentage and less than 90 percentage. An independent claim is also included for a method for subsequent upgrading of a tunnel with an explosion protection against inner space explosions.</p> |
