The invention relates to an anchoring kit for a drilling machine provided with a frame, the anchoring kit including at least a first anchoring module having: a first part including an anchoring device for immobilizing the first part in the soil; a second part including a device for fixing to the frame; and a displacement device for moving the second part relative to the first part along a first direction.

Various methods of making a reinforced structure in the ground using a boring tool are provided. One of the methods includes providing a boring tool having a boring tube that can vibrate. The method also includes making a borehole in the ground using the boring tool while causing the boring tube to vibrate. Additionally, the method includes, when the boring tube has reached a predetermined depth, injecting a sealing grout into the boring tube that embeds the boring tube in the sealing grout. Further, the method includes detaching the boring tube from the boring tool, thereby providing a structure reinforced by the boring tube.

Systems and methods for fabricating a retaining wall include an operation for making an untreated wall in the ground. This may be done by digging a trench in the ground and simultaneously mixing the ground in situ with a binder. Next may be a further operation for excavating a volume of ground adjacent to the untreated wall so as to uncover a surface of the untreated wall. Following that may be a further operation for treating the untreated wall during which a protective treatment substance comprising a polymer substance is applied to the surface that was uncovered in such a manner as to obtain a retaining wall of a thickness that is substantially equal to the thickness of the untreated wall.
