Abstract: A shock energy dissipation traffic divider barrier comprises a plurality of aligned energy dissipating members (1) slidably supported on a bearing surface (2), each of the dissipating members having a guide extending transversely therethrough. An anchoring cable (4), fastened at a point before the first or leading dissipating member, extends through each of the dissipating members in slidable engagement with its guide and is connected to a shoulder (5) behind the last of the dissipating members with a compression spring (6).

Abstract: A structure for the containment of natural and/or artificial embankments, said structure being made up of a plurality of modular envelopes (1), each one of said envelopes (1) being made up of a tub-like fore member (2), whose fore wall (5) is at a slope with respect to the vertical direction; as well as of two transverse members (4) which are provided with fore hammer-like members (8, 9), i.e., lower and upper hammer-like members, which members couple with a suitable seat (7) obtained in the side walls (6) of said tube-like member (2) belonging to the same envelope (1) and to that in the adjacent position; and of a back longitudinal member (3) that bears on its side ends hammer-like members (12, 13) for realizing the coupling with corresponding hammer-like members (10, 11) provided at the back position on the transverse members (4) of the envelope (1) to which it belongs or of the upper envelope.
