Abstract

A soil reinforcing device for reinforcing a ground supporting a load structure, wherein said soil reinforcing device comprises a first assembly comprising:
a plurality of cells extending vertically and forming a cell mesh; a plurality of draining devices extending vertically and located in said cells.

First claim

The invention claimed is:

1. A soil reinforcing device for vertically reinforcing a ground supporting a load structure, wherein said soil reinforcing device comprises a first assembly including:
a plurality of cells extending in the ground vertically and forming a cell mesh, each cell comprising vertical walls;
a plurality of draining devices comprising columns, extending vertically and located within a volume of the cells, separated from the vertical walls.

2. The soil reinforcing device according to claim 1 , wherein each cell comprises one draining device.

3. The soil reinforcing device according to claim 1 , wherein each cell comprises six vertical walls, and the cell mesh forms a honeycomb-type structure.

4. The soil reinforcing device according to claim 1 , wherein said vertical walls are connected to each other by linking columns.

5. The soil reinforcing device according to claim 4 , wherein said linking columns are jet-grouted columns or concrete columns.

6. The soil reinforcing device according to claim 1 , wherein the vertical walls comprise a mixture of cut ground with a binder.

7. The soil reinforcing device according to claim 1 , wherein the draining devices extend in the middle of said cells.

8. The soil reinforcing device according to claim 1 , wherein said draining devices extend deeper than said cells.

9. The soil reinforcing device according to claim 1 , further comprising a second assembly that includes exterior columns, wherein said second assembly, considered in a horizontal plane, surrounds the first assembly.

10. The soil reinforcing device according to claim 9 , wherein said exterior columns comprise exterior stone columns.

11. A system comprising:
a soil reinforcing device for vertically reinforcing a ground supporting a load structure, wherein said soil reinforcing device comprises a first assembly including:
a plurality of cells extending in the ground vertically and forming a cell mesh, each cell comprising vertical walls;
a plurality of draining devices comprising columns, extending vertically and located within a volume of the cells, separated from the vertical walls; and

a load structure vertically supported by said first assembly.

12. The system according to claim 11 , wherein:
the load structure has a load structure diameter;
the first assembly has a first assembly diameter; and
wherein the first assembly diameter is greater than the load structure diameter.

13. The system according to claim 12 , wherein the load structure is a LNG tank.

14. A method for making a soil reinforcing device for vertically reinforcing a ground supporting a load structure, wherein said soil reinforcing device comprises a first assembly including:
a plurality of cells extending vertically and forming a cell mesh, each cell comprising vertical walls;
a plurality of draining devices comprising columns, extending vertically and located within a volume of said cells, separated from the vertical walls thereof;

wherein said method comprises forming the vertical walls of the cells using an in situ soil-mixing technique.
