End treatments and transitions for water-ballasted protection barrier arrays

摘要

An end treatment array for crash attenuation includes a transition barrier module formed of side walls, end walls, a top wall, and a bottom wall, wherein the module walls together define an enclosed interior space. The end treatment array further includes a containment impact sled having an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module.

主权项

1. An end treatment array for attenuating the forces generated by a vehicular impact, comprising:
a transition barrier module fabricated of plastic and comprising first and second side walls, first and second end walls, a top wall, and a bottom wall, the module walls together defining a substantially enclosed interior space which is hollow, the transition barrier module having a predetermined width and length; and a containment impact sled comprising an axially extending frame, said frame having a width sufficient to contain the transition barrier module within said frame when in an assembled configuration, and having an axial length which is at least one-half the length of said transition barrier module, the frame having an open end and an upright wall closing a second end thereof and defining an interior volume adapted for capturing debris during a vehicular impact; wherein the upright wall of the containment impact sled is attached to one end of the transition barrier module in said assembled configuration, so that the transition barrier module is disposed in said interior volume.
