Abstract
A civil engineering structure having an arched wall including a plurality of curve shaped elements. Each element bears against one or more other similar elements and has a recess arranged in an outer face for casting a concrete assembly capping piece and reinforcements. Each element also includes at least one rigid bearing piece fastened to the element and has, at a free end of the rigid bearing piece, a surface with a non-planar profile. The rigid bearing piece comes to bear against a similar piece of another element located opposite it. The two rigid bearing pieces have complementary profiles making it possible for them to be wedged vertically.

A set of interconnectable prefabricated concrete elements to form an arched wall of a civil engineering structure, each element comprising:
- a free end having an outer face;
- a recess formed in the outer face;
- a first set of reinforcements projecting from the outer face into the recess, the first set of reinforcements interconnecting the element to a corresponding first set of reinforcements of a corresponding element;
- at least one rigid bearing piece fastened to the outer face of the free end, each rigid bearing piece projecting from the outer face into the recess and having a free end surface with a non-planar profile;
- and
- a capping piece cast in the recess, wherein when the element is brought to bear against the corresponding element having at least one corresponding rigid bearing piece with a free end having a profile complementary to the non-planar profile of the element, the corresponding element being located opposite the element, the non-planar profile of the free end of each rigid bearing piece engages the complimentary profile of the free end of the corresponding rigid bearing piece of the corresponding element to ensure the wedging of the element and the corresponding element.
