Abstract
The application relates to a method for assessing the load bearing capacity of an inserted pile, including: applying, by a vibrator device arranged at the inserted pile, the inserted pile with a measuring pulse string during at least one vibration time period, detecting, by at least one detection module, motion data of the inserted pile caused by the measuring pulse string during a measuring time period, determining at least one downward motion data set from the detected motion data; and evaluating the downward motion data set such that a load bearing capacity criterion is determined.
Claims20
A method for assessing the load bearing capacity of an inserted pile, comprising:
- inserting the pile by a vibrator device with a maximum inserting frequency,
- applying, by the vibrator device arranged at the inserted pile, after the insertion of the pile the inserted pile with a measuring pulse string during at least one vibration time period, wherein a maximum measuring frequency of the measuring pulse string is at most 80% of the maximum inserting frequency,
- detecting, by at least one detection module, motion data of the inserted pile caused by the measuring pulse string during a measuring time period,
- determining at least one downward motion data set from the detected motion data;
- and
- evaluating the downward motion data set such that a load bearing capacity criterion is determined.
A measuring system, comprising:
- a vibrator device configured to insert a pile with a maximum inserting frequency,
- at least one control module configured to control the vibrator device arranged at the inserted pile in such a way that the inserted pile is applied with a measuring pulse string by the vibrator device during at least one vibration time period, wherein a maximum measurement frequency of the measuring pulse string is at most 80% of the maximum inserting frequency,
- at least one detection module configured to detect motion data of the inserted pile caused by the measuring pulse string during a measuring time period,
- at least one determination module configured to determine at least one downward motion data set from the detected motion data, and
- at least one evaluation module configured to evaluate the downward motion data set such that a load bearing capacity criterion is determined.
A computer program product having instructions executable on a processor, wherein the instructions are adapted to cause the processor to perform the following steps:
- controlling a vibrator device for inserting a pile with a maximum inserting frequency
- controlling the vibrator device arranged at the inserted pile in such a way that the vibrator device applies a measuring pulse string to the inserted pile during at least one vibration time period, wherein a maximum measurement frequency of the measuring pulse string is at most 80% of the maximum inserting frequency,
- detecting motion data of the inserted pile caused by the measuring pulse string during a measuring time period,
- determining at least one downward motion data set from the detected motion data;
- and
- evaluating the downward motion data set such that a load bearing capacity criterion is determined.
