- A gabion, comprising: - a cage basically box-shaped, and the cage comprises a bottom, located at the base of the cage, two frontal walls (12, 13), that are located on the two opposite lateral sides of the cage, and two side walls (14, 15), that are located on the two other side walls of the cage, the bottom, the frontal walls and the side walls are formed respectively from meshes (11.1, 12.1, 13.1, 14.1, 15.1) that are fixed one to the other, and - two compartmenting partitions (20, 30), which each fixedly connect the side walls to each other inside the cage in such a way that the internal volume of the cage is split into: - two frontal compartments (C1, C2), which are bounded respectively between one of the frontal walls and the one of the two compartmenting partitions that is closest to that frontal wall and between the other frontal wall and the other compartmenting partition, and which are each filled with a filler material made up of aggregates that are too large to pass through the holes of the meshes of the bottom, the frontal walls and the side walls respectively, nor through the compartmenting partitions, in such a way that it is retained within those frontal compartments, and - an intermediate compartment, which is bounded between the compartmenting partitions and which is able to receive a granular acoustic insulation material, characterised in that the gabion further comprises at least one lifting partition (50, 60): - fixedly connecting the frontal walls (12, 13) to each other within the cage by extending through each of the frontal compartments (C1, C2) and the intermediate compartment, - being opposite the bottom, fitted with at least one grab handle (51, 61), and - being, for the part laid out in the intermediate compartment, adapted in order to enable the aggregates of the acoustic insulation material to pass through it in order that the acoustic insulation material may spread freely, within the intermediate compartment, on either side of the lifting partition (50, 60). - a cage basically box-shaped, and the cage comprises a bottom, located at the base of the cage, two frontal walls (12, 13), that are located on the two opposite lateral sides of the cage, and two side walls (14, 15), that are located on the two other side walls of the cage, the bottom, the frontal walls and the side walls are formed respectively from meshes (11.1, 12.1, 13.1, 14.1, 15.1) that are fixed one to the other, and - two compartmenting partitions (20, 30), which each fixedly connect the side walls to each other inside the cage in such a way that the internal volume of the cage is split into: - two frontal compartments (C1, C2), which are bounded respectively between one of the frontal walls and the one of the two compartmenting partitions that is closest to that frontal wall and between the other frontal wall and the other compartmenting partition, and which are each filled with a filler material made up of aggregates that are too large to pass through the holes of the meshes of the bottom, the frontal walls and the side walls respectively, nor through the compartmenting partitions, in such a way that it is retained within those frontal compartments, and - an intermediate compartment, which is bounded between the compartmenting partitions and which is able to receive a granular acoustic insulation material, - two frontal compartments (C1, C2), which are bounded respectively between one of the frontal walls and the one of the two compartmenting partitions that is closest to that frontal wall and between the other frontal wall and the other compartmenting partition, and which are each filled with a filler material made up of aggregates that are too large to pass through the holes of the meshes of the bottom, the frontal walls and the side walls respectively, nor through the compartmenting partitions, in such a way that it is retained within those frontal compartments, and - an intermediate compartment, which is bounded between the compartmenting partitions and which is able to receive a granular acoustic insulation material, - fixedly connecting the frontal walls (12, 13) to each other within the cage by extending through each of the frontal compartments (C1, C2) and the intermediate compartment, - being opposite the bottom, fitted with at least one grab handle (51, 61), and - being, for the part laid out in the intermediate compartment, adapted in order to enable the aggregates of the acoustic insulation material to pass through it in order that the acoustic insulation material may spread freely, within the intermediate compartment, on either side of the lifting partition (50, 60).
