Abstract (en)
A geological probing device (10) is disclosed. The probing device comprises a hollow probing rod (1) to be extended into the geological matter to be probed during rotation thereof, and a CPT probe (2) fitted to the probing rod (1) to be pushed into the geological matter by said probing rod. The rod (1) is arranged to rest on the CPT probe (2) during penetration thereof into the geological matter. The probing device further comprises a pressure withstanding bearing (7) arranged between the probing rod (1) and the CPT probe (2), and arranged to prevent rotation of the CPT probe during rotation of the probing rod.
