Abstract (en)
Method for arranging a foundation pile in a soil, comprising the following steps:- providing a tube assembly comprising a tube having a tube center line, the tube forming an interior space, wherein a drill head is attached at the distal end or introduction end of the tube, wherein the drill head is provided with at least one cutter, wherein the drill head is provided with at least one passage that opens to the outside and is capable of being brought into fluid communication with the interior space,- introducing the tube with the rotating drill head at the lower end into the soil, according to an introduction track, wherein the cutter of the rotating drill head dislodges soil material,- during at least one first section of the introduction track via the interior space pressing grout towards the passage in the drill blade at a first pressure,- pressing the grout out of the passage to enable the grout to mix with the soil material, in particular sandy soil material, dislodged by the drill head,- characterized in that, the relative displacement of grout or mixture of grout with soil material is limited in proximal direction by a cross-plate or transverse flange that is attached near the distal end of the tube assembly, in particular to the drill head, and extends around the tube assembly, said cross-plate or transverse flange extending substantially radially to the outside relative to the tube center line, and being situated at the proximal side of the drill head.
