MODULAR BARRIER

摘要

The present invention is a modular barrier unit (10), a number of which are used for erecting a modular barrier. The follow modular barrier unit (10) of the invention comprises first (20) an second (30) longitudinal ends; opposing side walls (40); and upper and lower surface. The side walls comprise inwardly and outwardly extending portions which enable the unit to be connected to an adjacent barrier unit and to accommodate ballast material without causing a significant change in the shape of its walls. Barriers constructed from the modular barrier units (10) of the invention can be used in many applications, "e.g. flood barriers, lane dividers on highways, walls around construction sites, and defensive barriers at checkpoints and around strategic installations.
