摘要

A device for sealing of the walls of the engineer structures made of concrete, preferably of underground tunnel constructions, wherein the first sealing layer as a geotextile on the building - / tunnel wall is arranged and a second, to be applied by means of a hot air device, combined layer of a further geotextile and a plastic web is applied, wherein the sealing strips on a rail vehicle as a laying carriage, which rollers are arranged, which can be unrolled and the laying carriage has a pivotable pressing beam, characterized in that at the laying carriage a hydraulically controlled, a pivotable extension arm system is fixed, which, at least one lever arm (1; 2), as well as at least one hydraulic cylinder (3; 4, 5; 6) and a path - measuring system, wherein between the lever arms (1; 2), which is constructed as a central tube, and flexibly mounted by means of at least one universal joint (9; 10) with the outrigger system (1; 2), which is connected to the pressing beam (11) is arranged, on the one hand, with at least one holder (12), at least one in the form of a boom (13) is pivotable - and holding device is constructed as well as at least one pinch roller (14) is provided as well as on the other hand via a retaining profile..
