Definitions

• the present invention relates to a construction element, including concrete, for producing retaining walls.
• each construction element is intended to cooperate in superposition with at least one similar construction element.
• Each element has a top face, a bottom face, a front face and a rear face and at least two elongated section cells opening on the top face and the bottom face, these two cells being substantially aligned. parallel to the back side.
• Each construction element has on its underside two projecting notches which can engage substantially without play in cells opening on the top face of a lower element.
• the object of the present invention is to create construction elements of the aforementioned type which make it possible to make a retaining wall that can have a certain curvature, while being sufficiently wedged relative to each other to ensure the stability of the wall. .

• Each of the elements comprises a top face 1, a bottom face 2, a front face 3 and a rear face 4 and cells whose two recesses 5, 6 of elongate section opening on the top face 1 and on the bottom face 2. These two elongated cells 5, 6 are aligned substantially parallel to the rear face 4.
• each construction element comprises (see FIGS. 2 and 3), on its bottom face 2 and in a central zone thereof, a protruding part 7, for example of rectangular section, being able to engage with clearance in one of said recesses 5, 6 of elongate section, as shown in FIG. 5.
• Figures 3 and 4 further show that the underside 2 of an element of The construction comprises a first protruding rib 8 which extends parallel to the rear face 4 of the element along the inner longitudinal edge 5a of one of the elongate cells.
• the bottom face 2 of the element further comprises a second projecting rib 9 which extends in the extension of a portion of the rear face 4 of the element.
• Each of the ribs 8, 9 extends from one end of the element to a point beyond the middle of the element.
• the height of the ribs 8, 9 is equal to the height of the projecting portion 7, so that when the bottom face 2 rests on a plane ground, the ribs 8, 9 and the projecting portion 7 simultaneously take support on this ground by ensuring its stability and anchoring to the ground when it is loose.
• the ribs 8, 9 and the projecting portion 7 are shown hatched to show that they are projecting.

• Figures 1 and 5 show that the rear face 4 of each element is connected to the front face 3, on each side, by a face 13, 14 of circular section which is convex on one side and concave on the other, so that it can fit together with a face complementary to a neighboring element, as indicated in FIG. 5.
• the radius of these faces 13, 14 of circular section is such that it makes it possible to arrange two adjacent elements at a certain angle to make a wall retaining a certain curvature.
• Figures 1 and 5 show a part of retaining wall in which the rows are offset relative to each other by a length which is adjustable along the length of the cell 6 in which is engaged the protruding part 7.
• the offset is half a length of element.
• the retaining wall may comprise, at the ends of certain rows, half-elements whose structure substantially corresponds to the cutting of a standard element as shown in Figures 2 and 3 following a plane perpendicular to the length of an element and passing through the middle of a projecting portion 7. Such half-elements are shown in Figures 6 to 11.
• the ribs 9a and 8a are also present but their length is shorter.
