  • Method for compaction detection and control when compacting a soil with a deep vibrator
    Patent number: 10385530
    Abstract: A method for detecting and controlling compaction when compacting a soil by a depth vibrator which has a rotationally drivable imbalance (3) and at least one sensor (6, 12, 13, 14, 19), comprising the steps of: inserting the depth vibrator (2) into the soil (17) up to a desired final depth (Tm); compaction of the soil (17) during which the forward angle (?) of the imbalance (3) as well as the oscillation amplitude (A) of the depth vibrator (2) are determined; detection of a soil stiffness profile from soil stiffness values (k) determined over time (t); determination of a first soil stiffness value (k1) and a second soil stiffness value (k2) from the soil stiffness profile (k), for which it applies that a rate of increase (k?2) of the second soil stiffness value (k2) exceeds a rate of increase (k?1) of the first soil stiffness value (k1) by a defined factor; calculation of a transition soil stiffness value (k12) which is between the first soil stiffness value (k1) and the second soil stiffness value (k2); a
