Abstract

Verfahren zur Baugrundverbesserung durch Einbringen von Säulen 11 in den Boden, die gemäß einem Raster über die Oberfläche verteilt sind und die jeweils einen unteren abgebundenen Säulenabschnitt 12 aus abbindbarem Material wie Mörtel oder Beton und jeweils einen oberen verdichteten Säulenabschnitt 13 aus rolligem Material wie Schotter haben, wobei beim Herstellen des unteren Säulenabschnitts 12 ein Hohlwerkzeug unter Verdrängung des Bodens niedergebracht und das abbindbare Material beim Ziehen des Hohlwerkzeugs aus diesem heraus in das Bohrloch 27 eingebracht wird.

Figure imgaf001
A method for ground improvement by placing columns 11 in the ground, which are distributed over the surface according to a grid and which each have a lower set column portion 12 of settable material such as mortar or concrete and a respective upper compacted column portion 13 of rolligem material such as gravel, wherein in producing the lower pillar portion 12, a hollow tool is drilled while displacing the soil, and the settable material is introduced into the borehole 27 as the hollow tool is pulled therefrom.
