  • Each barrier comprises a lower part which supports an upper part placed on top of the lower part.
  • the lower supporting part comprises a plurality of segments which are lined up along the direction of extension of the barrier and which are in the form of identical, structurally resistant segments placed on a structurally resistant foundation of corresponding dimensions.
  • the lower part is divided into prefabricated segments made of reinforced concrete, which are aligned along the longitudinal direction of extension of the barrier and which are adapted to fully support the upper, preferably metallic, part of the selfsame barrier.
  • These underlying supporting segments which are the same as each other in structure and function, are excessively heavy and difficult to position.
  • each segment must be placed on a bulky and suitably reinforced foundation which entails considerably lengthy preparations and high production costs.
  • the invention accordingly provides a barrier according to claim 1.
