Abstract

Die Erfindung betrifft ein Verfahren zur Bestimmung einer Bodeneigenschaft mittels einer Bodenverdichtungsvorrichtung, die zum Verdichten von Untergründen geeignet ist und die eine schwingend beaufschlagte Bodenplatte zur Bodenverdichtung aufweist, wobei die Bodenplatte insbesondere von einem motorisch angetriebenen Schwingungserreger in eine gerichtete Schwingung versetzt wird, mit wenigstens einem Sensor, der die Beschleunigungen der Bodenplatte in vertikaler Richtung erfasst und an eine Messeinrichtung übermittelt, die basierend auf den Beschleunigungen der Bodenplatte absolute Verdichtungskennwerte während der Bodenverdichtung ermittelt und verfügbar macht, wobei in einem Einrichtungsbetrieb der Bodenverdichtungsvorrichtung eine Korrelation zwischen dem Schwingungsverhalten, vorzugsweise den Beschleunigungen der Bodenplatte oder eines hieraus ermittelten Wegsignals der Bodenplatte, und den absoluten Verdichtungskennwerten erstellt und in der Messeinrichtung hinterlegt wird, und dass die Messeinrichtung während des Verdichtungsbetriebs die Beschleunigungen der Bodenplatte ermittelt und derart transformiert, dass diese als Eingabewerte für die hinterlegte Korrelation geeignet sind, und dass die Messeinrichtung mittels des Eingabewerts und der Korrelation einen absoluten Verdichtungskennwert bestimmt.

The invention relates to a method for determining a soil property by means of a soil compacting device, which is suitable for compacting substrates and having a swinging acted bottom plate for soil compaction, wherein the bottom plate is placed in particular by a motor-driven vibration exciter in a directional vibration, with at least one sensor which detects the accelerations of the bottom plate in the vertical direction and transmitted to a measuring device, which determines and makes available based on the accelerations of the bottom plate absolute compression characteristics during soil compaction, wherein in a Einrichtungsbetrieb the soil compacting device, a correlation between the vibration behavior, preferably the accelerations of the bottom plate or a path signal of the base plate determined therefrom, and the absolute compression characteristics are created and stored in the measuring device, and the measuring device determines the accelerations of the bottom plate during the compacting operation and transforms them to be suitable as input values for the deposited correlation, and that the measuring device determines an absolute compacting value by means of the input value and the correlation.
