BAUMASCHINE, VERDRÄNGERROHR UND VERFAHREN ZUM ERSTELLEN EINER FÜLLGUTSÄULE IM BODEN
The invention relates to a construction machine for introducing a displacement tube into the ground, wherein the displacement tube comprises a tube base body and, at its lower end, a closure device which comprises at least one closure flap which is adjustable between a closed position, in which the displacement tube is closed downwards by the at least one closure flap, and an open position, in which filling material is discharged from the displacement tube into the ground for forming a filling material column, wherein the construction machine comprises a feed drive for introducing and retracting the displacement tube into and out of the ground, respectively. According to the invention, it is provided that an actuating unit with at least one pressing-on element is arranged on the construction machine, by means of which the at least one closure flap is adjustable from the open position into its closed position and retainable in said position before contacting the ground at least until the closed closure flap penetrates into the ground. The invention further relates to a method for creating a filling material column.
