Abstract (en)
[origin: EP0391127A1] The device consists of guide rails (13, 14) inserted in pairs into a suspension-filled slot (10) in the earth. The ends of a sealing membrane (12) are guided on the guide rails (13, 14) during the lowering. The two rails (13, 14) are mounted on the guiding wall (40) of the slot (10) in the earth by self-aligning bearings (38, 39) so that they can be aligned exactly vertically and parallel to one another on account of their dead weight. In addition, both guide rails (13, 14) are provided with sliding rails (27, 28). The membrane sheet (12a, 12b) to be lowered is fastened to a weighted horizontal spacer (31) which is guided laterally in the sliding rails (27, 28) via carriages (29, 30). In this way, canting of the membrane sheet (12a, 12b) in the guide rails (13, 14) is avoided during lowering, the spacer (31) ensuring the parallelism and alignment of the guide rails (13, 14). <IMAGE>
