FLOATING BARRIER UNITS

摘要

A number of individual barrier units (10;300) form a floating barrier wall each comprising a housing (310) formed in the general shape of a highway barrier having a top wall (12,302), a bottom wall (14,304), opposed end wall s (16, 18, 306, 308,), and, opposed side walls (20,22) interconnected to form a hollow interior (24,312) which is preferably partially or completely filled with a foam material (84, 86, 314). A ballast weight (92, 98, 114,136, 338) is secured to each barrier unit, either inside (92, 114, 136) or outside (98, 182) of the hollow interior (24) , to maintain them in an upright position i n the water. Cables (360, 414), couplers (348) and/or other connectors are employed to mount adjacent barrier units end-to-end to form a barrier wall which can encircle a vessel or otherwise isolate an area within a seaport or other body of water to provide security.
