DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention has for its object a retaining wall adapted to be decorated with vegetation, consisting of dry mounted construction elements, by interfitting within each other, and by superpositioning on each other, each element being of the type constituted by an open-bottom shell.
BACKGROUND OF THE INVENTION
The state of the art can be defined by the following patents:
EP-0 215 991: retaining wall adapted to be decorated with vegetation, and consisting of dry mounted construction elements interfitting within each other, and by superposition on each other, each element being of the type constituted by an open-bottom shell comprising vertical partitions characterized by the fact that a first vertical partition, parallel to the upstream wall of the shell, delimits a large space on the downstream side which serves as a flowerpot and at least one upstream space which serves as recesses for roots for the upper shell mounted rearwardly, offset upstream on the lower shell, this latter space being divided into at least two smaller spaces by a second vertical partition perpendicular to the upstream wall and to the first partition, the size of the upstream spaces is such that when the shells are superposed on each other, the roots, which leave the upper shell, can only proceed toward the ground and not into the lower shell, which is to say that the vertical partition of the upper shell registers with the upstream wall of the lower shell.
The construction element is constituted by two adjacent shells produced as a single block.
It comprises grooves on the side walls of the shell, so as to permit the shells to interfit within each other.
DE-U-7 824 776: this document describes an element for retaining constructions for embankments, natural slopes or earth works. It is formed from an open-bottom shell in the shape of a cube with a vertical partition which separates the shell into two equal recesses, said shell perpendicularly connects the upstream wall and the downstream wall. Lateral blockage of the element is ensured by two shoulders, the first shoulder is provided in the medial portion of the upper edge of the side wall to extend along the upstream wall and to terminate on the upper edge of the other side wall facing the point of departure of the first shoulder.
FR-A-2 550 812: this invention has for its object to improve the operation of a mechanical wall by various features of novelty. There should be noted for example the use if desired of more economical elements because they are technically easier to make, or else lighter, requiring less material for their fabrication and easier handling. There should also be noted the use if desired of additional elements, or of interfitting partitions, in lieu of a normal element; the saving thus realized is considerable. Another improvement relates to the adaptation to the elements of a system of lateral positional variation permitting changing as desired the inclination of the wall according to its mounting; this system permits better adaptation to the environment and infinite architectural combinations.
EP-A-0 362 110: retaining wall adapted to be decorated with vegetation, and constituted by dry mounted construction elements, interfitting within each other, and by superposition on each other, each light element being of the type constituted by an open-bottom shell comprising two external side vertical walls, and vertical partitions, a first vertical partition, parallel to the upstream wall of the shell, delimits a large space downstream which serves as a flowerpot and at least one upstream space which serves as recesses for roots for the upper shell mounted rearwardly, offset upstream on the lower shell, this latter space being divided into at least two smaller spaces by a second vertical partition perpendicular to the upstream wall and to the first partition; the size of the upstream spaces is such that when the shells are superposed on each other, the roots which leave the upper shell can only go toward the ground and not into the lower shell,
