Abstract (en)

[origin: WO2019123212A1] A method for strengthening soils comprising: a step of making in the soil (1) a hole (2) that has a main line of extension which is at least mainly vertical; 5 a driving step wherein a micro-pile (11) is driven into the soil (1) at the hole (2); and a step of filling the hole (2) with a solidifiable material or with a compactable solid granular material; wherein the step of making the hole (2) in the soil (1) comprises an inserting step wherein a punch (4) is inserted in the soil (1) by applying a pressure to the punch, the punch comprising a lower tip (5) insertable in the soil (1), a top portion (6) opposite to the lower tip (5), an axis of extension that extends between the top portion (6) and the lower tip (5) and a cross-section that increases along the axis of extension going away from the lower tip (5), and 5 wherein the step of inserting the punch (4) in the soil (1) also causes compression and compacting of the soil (1) surrounding the hole (2).
