Cable-reinforced barrier

Abstract

A barrier is formed from bollards and posts that are embedded in a terrain. The bollards and posts are interconnected by, and support, vertically-spaced runs of primary rails. The rails in each run are aligned in end-to-end relationship. A strengthening cable extends within each run, and is anchored at each end within a concrete-filled bollard. Each bollard contains an elongate, vertically-oriented cable entry port that can receive the end portions of all of the cables in the runs, disposed in laterally-spaced relationship. A two-part closure covers the cable entry port, and includes spaced cable openings that maintain the cables that exit the bollard at a desired lateral separation distance. A cable confinement bracket installed at each post prevents the cables from flying out of the primary rails after an impact. The bracket features a spine that restrains the cables, which pass through bays notched in the spine's lower edge. Each cable may include attached cable clips to enhance the cable's resistance to pullout from the bollards.
