Embankment formed by preformed collaborating assemblable elements, in particular for road or railway constructions, and process

摘要

Prefabricated concrete assemblable elements are fastened together so as to form a light cellular leading structure with high resistance. The elements can be three-dimensional, box-shaped or angle-shaped, or they can be of a two-dimensional board type, provided with connection joints at their edges. A lower slab and an upper slab, preformed or laid in situ, complete the embankment and allow the elements to cooperate.
