<p>A block for a retaining wall comprises a front face (13) intended to form part of a visible side of a retaining wall, and a support face (11) intended to support and bear, in the production of the visible side, at least one similar overlying block. The support face (11) is angled with respect to the front face (13) and traversed by at least one through opening (15) which defines at least one internal abutment surface (16, 17) placed at a first predetermined distance from the front face. Reference means (23) protrude from the support face at least at a second predetermined distance from the front face, in order to come into abutment, in use, against the at least one internal abutment surface of the similar overlying block and thus prevent the displacement thereof in only one of the two directions which are transverse to the front face. The reference means (23) comprise at least one flattened engagement portion (24). At least one slot (22) elongate in a direction transverse to the front face is provided on the support face (11) to receive the corresponding flattened engagement portion of the reference means (23).</p> |
