Abrégé

A soil probing device includes a probing rod with a measuring probe, a driving for penetrating the probing rod into the ground, generators for generating acoustic compression and shear waves into the ground, detectors for detecting the generated acoustic compression and shear waves. The detectors are built into the measuring probe. Also the generators are built into the measuring probe at positions that are interspaced at fixed distances in a z-direction from the detectors in the measuring probe. A processing unit CPU is provided for calculating velocities of the generated acoustic compression and shear waves that get to travel from the generators towards the detectors through local ground layers that lie adjacent the measuring probe in between the generators and detectors.

Abrégé

A soil probing device for determining properties of soil during penetration into ground using a soil probing device. The soil probing device has a measuring probe, a plurality of rod sections each having a central axis for assembly of the probing rod, driving means for penetrating the probing rod into the ground, and a measuring means for determining properties of the ground during penetration of the probing rod into the ground. The probing rod while penetrated into the ground is extendable each time by a new one of the rod sections. Each of the rod sections are provided at their outer ends with complementary male and female locking parts which in an axially aligned position of adjacent rod sections, are movable relative to each other from an unlocked into a locked position and from the locked position into the unlocked position.
