ABSTRACT:
Barrier elements couple together into a longitudinal wall to provide security from terrorist threats by being able to withstand both vehicle collisions and explosive blasts. Each barrier element is prefabricated to include a massive block of durable material, preferably high strength concrete, cast about one or more beams that are preferably made of steel and extend longitudinally through the block. Multiple blocks are positionable on top of the ground with their beams coupled longitudinally to one another, end-to-end. Forces from a vehicle collision or an explosive blast can cause barrier elements to rotate relative to one-another when the couplings between beams hinge or bend as the durable material that interferes with the rotation breaks away. The barrier elements are transportable by truck, positionable using readily available heavy lifting equipment, and longitudinally inter-connectable hingedly or rigidly by means of field-installable mechanical fastening hardware.
