ABSTRACT:
A protection barrier system for energy-absorption of impacts includes an elongated barrier defining a chamber therein. The barrier includes side walls having a plurality of connected non-vertical wall segments and a plurality of buttresses positioned vertically at spaced apart locations along each side wall. One or more guide channels are positioned on each side wall in horizontal alignment with similar guide channels on like-configured barriers. A coupling is disposed on each opposed end of the barrier for coupling of either barrier end juxtaposed in end-to-end nested arrangement with like barriers. A supplemental energy-absorbing system is connectable between opposed ends of end-to-end coupled barriers, providing energy-absorbing tubes removably inserted through each guide channel of each barrier. Cables are extendable through the tubes in the guide channels of the nested barriers, providing additional energy-absorption and deterrence from breaching of the barriers. A method of manufacture for the protection barrier is also disclosed.
