FLEXIBLE IMPERVIOUS BAG FOR SUSPENDED LOAD TESTS

摘要

The invention relates to a flexible impervious bag (1) which is used for suspended load tests. The inventive bag is characterised in that the case (2) thereof comprises an inner layer (5) and an outer layer (6) which are made from a vulcanised elastomer. In addition, at least one other intermediate layer (7-10) is disposed between the inner and outer layers, said intermediate layer being made from fabric and/or foam and/or elastomer. Moreover, resistance to perforation and/or tearing or bursting constitutes the main characteristic of each intermediate layer (7-10) or each intermediate layer is self-sealing.
