rotary pressure sounding

"2.9.3 Rotary pressure sounding
Rotary-pressure sounding is a Norwegian method developed in the 1960’s (see Statens
vegvesen, 1997). It uses a twisted tip and it is manufactured from a steel bar with a rectangular
cross-section of 25 x 41 mm, which is twisted and then shaped into a conical tip at the lower end.
One of the outer ridges of this screw is supplied with an extra hard welded top; see figure 4(a)
the length of the tip is 225 mm and the projection of the cross-section has a diameter of 55 mm.
The tip is attached to φ 36 mm sounding rods and pushed down into the soil at a rate of 3 ± 0.5
m/min while rotating at 25 ± 5 rpm. The drill rig shall provide a pushing force of at least 30 kN
and a torque of about 1 kNm. Rotary pressure sounding was extensively used in Norway up to
about 1990. Thereafter it has been gradually replaced by the now predominant total sounding method"
