PIPE RACK CRASH CUSHION

摘要

A collapsible divider end treatment or crash cushion formed by a pipe rack frame that retains a number of axially disposed barrels, each of which contains crushable modules. The frame further features a slidable guide or guides which constrain the barrels and provide additional strength to the end treatment during an impact that does not proceed directly along the longitudinal axis of the barrels. This allows the end treatment to substantially redirect impacting vehicles in a desirable manner. In a preferred embodiment, the crash cushion employs barrels containing an energy-absorbent module that is useful for absorbing energy during a vehicular crash. The pipe rack crash cushion of the present invention provides a low cost alternative to conventional crash cushion. In addition, the pipe rack crash cushion allows the decelcaration force provided by the crash cushion to be easily adjusted. The pipe rack of the present invention is also advantageous in that it can be rebuilt easily and inexpensively following a collision.
