Abstract (en)
[origin: WO2019053615A1] The invention relates to a concrete precast unitary draining pile (2) and a draining retaining wall (1) comprising a plurality of these piles. The pile, of at least 4 metres in length and of a maximum diameter between 40 and 150 cm, is provided with a longitudinal opening (26) intended for draining water vertically through the pile. The retaining wall comprises a plurality of these piles, each pile comprising a first portion driven into a hole (50) in the ground (5) and a second portion extending vertically above the ground. The wall may comprise panels (3) between the piles intended for holding back the ground (6). The method of assembling a retaining wall comprises a step of drilling at least two boreholes, inserting a pile in each hole and casting or spraying concrete between said piles.
