Patent ID: 7144187

Claim:
A cabled massive security barrier located on top of a supporting surface and comprising: a first mass of composite material; wherein said mass of composite material comprises an interior region and an outer surface; wherein said outer surface includes two end regions spaced apart a distance along a longitudinal direction that is generally parallel to said supporting surface; wherein a tunnel defined by the mass of composite material extends longitudinally through said interior region and between said end regions; wherein a cross-sectional dimension of said tunnel increases both smoothly and nonlinearly up to at least one of said end regions along at least a portion of distance between said end regions to comprise a smoothly tapered opening; wherein cable can be routed through the tunnel to protect the cable from damage by an explosive blast and to protect the cable from shear damage at the end regions of the tunnel; wherein the massive security barrier can be cabled to adjacent and similar massive security barriers; and wherein the massive security barrier is free to slide along the supporting surface; whereby said cabled massive security barrier provides for slowing a moving vehicle that collides with it, provides at least partial protection against a blast from a nearby explosion event, and provides a tunnel through which a cable can be safely routed.
