Abstract

Weicher Boden wird durch Einbringen und Verdichten von trockenem mineralischem Pulver stabilisiert, das mittels einer drehangetriebenen Stopfwendel (4) in eine Bohrung (10) im Boden eingestopft wird. Die Axialkraft der Stopfwendel (4), vorzugsweise die Vorschubkraft eines axialen Vorschubantriebs der Stopfwendel (4), wird gemessen und auf einen jeweils vorgegebenen Wert gesteuert bzw. geregelt. Zur Steuerung bzw. Regelung der Axialkraft der Stopfwendel kann das Antriebsdrehmoment der Stopfwendel (4) gesteuert werden. Der vorgegebene Wert, auf den die Axialkraft geregelt wird, kann aus durch das Stopfen verursachten Lageänderungen des Planums, eines Baukörpers oder einer Verkehrsfläche im Stopfbereich bestimmt werden.

Soft soil is stabilized by introducing and compacting dry mineral powder, which is stuffed into a hole (10) in the soil by means of a rotary plug (4). The axial force of Stopfwendel (4), preferably the feed force of an axial feed drive the Stopfwendel (4) is measured and controlled or regulated to a respective predetermined value. To control or regulate the axial force of the Stopfwendel the drive torque of the Stopfwendel (4) can be controlled. The predetermined value, to which the axial force is regulated, can be determined from changes in position of the tarmac, a structure or a traffic area in the tamping area caused by the tamping.
