the ubiquitous barrier containment and / or ingestion of liquids

摘要

A barrier for confining or receiving liquids independently of position comprises hose elements (10, 20) which can be connected together via coupling elements (11, 21). In particular, the coupling elements may be of tubular design and connect the internal spaces of the hose elements together. It is particularly advantageous if the coupling parts each have two annular or circular flanges (11, 12) whose external diameter is less than the diameter of the liquid-filled hose element, and for this purpose commercial fire brigade couplings such as are used for connecting fire-fighting hoses may be employed. By setting back the coupling elements with respect to the face walls of the bead on the end face of the hoses, the adjacently situated beads of adjacent hose elements form an essentially annular sealing surface so that a barrier made up of a plurality of such hoses is able to withstand a high liquid pressure even at the seams formed by the hoses with one another and only minimal liquid losses occur.
