Abstract: The invention relates to a cast wall constituted by a succession of panels touching via their end edges and made by casting a binder in contiguous lengths of trench dug in the ground in line with one another, each panel including reinforcement, said wall further including link means between the reinforcements in two contiguous panels. The link means (24, 44) are separate from the reinforcement (22, 42) and comprise an anchor element (24) having a first end fitted with at least one vertical first locking element (28, 30) and a second end engaged in one of said panels (22), and a link element (44) having a first end provided with at least a second locking element (46, 48) suitable for co-operating with the first locking element, and a second end engaged in the other one of said panels (42).
