Abstract

A geotechnical apparatus comprising a holder with a coiled rod with a probe, such as a penetrometer, a rod bending/straightening device and a drive unit for both uncoiling the coiled continuous rod and pushing the uncoiled rod with the probe into the ground and for pulling such a rod with the probe out of the ground and recoiling the continuous rod, wherein the drive unit comprises two grippers to alternatingly grip the rod and move it along its longitudinal axis over a predefined length, the bending/straightening device has a first set of rollers, at least two of which are at one side of the rod and the remaining rollers are at an opposing side of the rod, such that the rollers convert the coiled rod to an essentially straight rod when uncoiling and convert the straight rod to a coiled rod of essentially constant coil diameter when coiling.
