Abstract
Abstract Mattress Gabions are provided for soil stabilization revetments, designed to halt erosion and/or to consolidate the soil. A protective revetment consisting of a structure of vegetable matter forms a mattress gabion which retains the soil inside each of a multiplicity of individual cells. Each cell of the container can be filled with earth or a soil or soil-forming mixture, encouraging the growth of vegetation inside the mattress, in order to afford a natural protection to the soil of banks or excarpments, etc. Once it has been filled, the mattress is closed by a top cover in double twist steel mesh, after laying a geosynthetic sheet between the two to keep in fine materials.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
A process for making a mattress gabion for stabilizing an earthwork, comprising the steps of: (a) forming a wire mesh structure having a bottom and a plurality of upwardly open cells defined between partitions constituted by upstanding folds of wire mesh unitary with the bottom and subdividing said structure into said cells and longitudinal and transverse walls and wire stitching said partitions to said longitudinal walls; (b) lining said partitions, said bottom and said walls internally of said cells with a geotextile material capable of retaining soil in said cells; (c) filling said cells with a vegetation-growth supporting medium; (d) applying a geotextile to said structure over said cells and said medium after said cells are filled with said medium; (e) affixing said geotextile to said structure by wire stitching it to said partitions and said walls at upper edges thereof; and (f) affixing a cover of wire mesh over said structure after filling it with said medium.
Claim 2
Dependent Claim
158 words
A process for making a mattress gabion for stabilizing an earthwork, comprising the steps of: (a) forming a wire mesh structure having a bottom and a plurality of upwardly open cells defined between partitions constituted by upstanding folds of wire mesh unitary with the bottom and subdividing said structure into said cells and longitudinal and transverse walls and wire stitching said partitions to said longitudinal walls; (b) lining said partitions, said bottom and said walls internally of said cells with a geotextile material capable of retaining soil in said cells; (c) filling said cells with a vegetation-growth supporting medium; (d) applying a geotextile to said structure over said cells and said medium after said cells are filled with said medium; (e) affixing said geotextile to said structure by wire stitching it to said partitions and said walls at upper edges thereof; and (f) affixing a cover of wire mesh over said structure after filling it with said medium.
Claim 3
Dependent Claim
45 words
The process defined in claim 1 wherein said geotextile material fully lines all of said bottom, said partitions and said walls, said process further comprising the step of stitching said geotextile material to said wire mesh structure at least at said walls and said partitions.
Claim 4
Dependent Claim
21 words
The process defined in claim 2 wherein said geotextile material is affixed to said partitions and said walls as separate panels.
Claim 5
Dependent Claim
23 words
The process defined in claim 2 wherein said geotextile material is affixed to said partitions and said walls as a single continuous sheet.
Claim 6
Independent Claim
173 words
A method of stabilizing and earthwork, comprising the steps of: forming a mattress gabion by: shaping a wire mesh structure having a bottom and a plurality of upwardly open cells defined between partitions constituted by upstanding folds of wire mesh unitary with the bottom and subdividing said structure into said cells and longitudinal and transverse walls and wire stitching said partitions to said longitudinal walls, lining said partitions, said bottom and said walls internally of said cells with a geotextile material capable of retaining soil in said cells, filling said cells with a vegetation-growth supporting medium, affixing a cover of wire mesh over said structure after filling it with said medium, and applying a geocompound to said structure over said cells and said medium after said cells are filled with said medium and prior to the application of said cover thereto, and affixing said geocompound to said structure by wire stitching it to said partitions and said walls at upper edges thereof; and applying said mattress gabion to an earthwork to stabilize same.
Claim 7
Independent Claim
173 words
A method of stabilizing and earthwork, comprising the steps of: forming a mattress gabion by: shaping a wire mesh structure having a bottom and a plurality of upwardly open cells defined between partitions constituted by upstanding folds of wire mesh unitary with the bottom and subdividing said structure into said cells and longitudinal and transverse walls and wire stitching said partitions to said longitudinal walls, lining said partitions, said bottom and said walls internally of said cells with a geotextile material capable of retaining soil in said cells, filling said cells with a vegetation-growth supporting medium, affixing a cover of wire mesh over said structure after filling it with said medium, and applying a geocompound to said structure over said cells and said medium after said cells are filled with said medium and prior to the application of said cover thereto, and affixing said geocompound to said structure by wire stitching it to said partitions and said walls at upper edges thereof; and applying said mattress gabion to an earthwork to stabilize same.
Claim 8
Dependent Claim
136 words
A mattress gabion for stabilizing an earthwork, comprising: a wire mesh structure having a bottom and a plurality of upwardly open cells defined between partitions constituted by upstanding folds of wire mesh unitary with the bottom and subdividing said structure into said cells, and longitudinal and transverse walls and wire stitching securing said partitions to said longitudinal walls; a lining of a geotextile material interiorly of said cells along said partitions and said longitudinal and transverse walls for preventing escape of soil from said cells; a filling of a vegetation-growth supporting medium in said cells; a cover of wire mesh stitched with metal wire to said structure and covering said cells and; a geocompound between said cover and said medium in said cells, said wire mesh structure and said cover being composed of hexagonal wire mesh.
Claim 9
Dependent Claim
136 words
A mattress gabion for stabilizing an earthwork, comprising: a wire mesh structure having a bottom and a plurality of upwardly open cells defined between partitions constituted by upstanding folds of wire mesh unitary with the bottom and subdividing said structure into said cells, and longitudinal and transverse walls and wire stitching securing said partitions to said longitudinal walls; a lining of a geotextile material interiorly of said cells along said partitions and said longitudinal and transverse walls for preventing escape of soil from said cells; a filling of a vegetation-growth supporting medium in said cells; a cover of wire mesh stitched with metal wire to said structure and covering said cells and; a geocompound between said cover and said medium in said cells, said wire mesh structure and said cover being composed of hexagonal wire mesh.
Claim 10
Dependent Claim
26 words
The mattress gabion defined in claim 6 wherein said lining is a single continuous sheet extending over all of said bottom, said partitions and said walls.
Claim 11
Dependent Claim
26 words
The mattress gabion defined in claim 6 wherein said lining is formed as separate panels on said partitions, said bottom and said walls and stitched thereto.
