#CMT# #/CMT# A barrier hose (1) and a support hose (2) fixed to it, together form the flood barrier. Filling connections with screw covers (3) are welded into upper surfaces of the hoses. Emptying connections with screw covers (4) are welded-into the sides of both hoses. At each end of the barrier hose a flat end face is formed by a honeycomb-cored plate with an aluminum covering layer. The plate is cut to the cross sectional shape of the barrier hose and welded-in. To couple barriers, complementary hook-and loop attachments (7, 8) are provided at both ends; these are supplemented by clamping components (9). #CMT#USE : #/CMT# A barrier against flood, high water or high tide. #CMT#ADVANTAGE : #/CMT# The frequency of so-called hundred-year floods is seen to be increasing considerably. To make a temporary dam 30 m in length, 1200 sandbags must be placed; they must also be removed afterwards. If there is harmful contamination, the bags become special waste, making disposal especially costly. The new barrier greatly simplifies deployment and storage. It is comparatively light in weight and can be rolled-up for storage when empty. It is easily cleaned after use. The hoses are filled with water under negligible pressure to an approximately elliptical cross section with a flat base. In comparison with a circular cross section, much greater resistance is offered against side displacement across the ground. The barrier moulds itself to the shape of the ground. The protective tube is not immersed, lying instead on the opposite side to the floodwater. Its weight holds the barrier tube down against the ground, increasing the resistance to side movement. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective view of the barrier. 1 : barrier hose 2 : support hose 3 : filling screw covers 4 : outlet screw covers 7, 8 : complementary hook-and loop attachments 9 : clamping components. |
