The most widely used method for measuring the undrained shear strength and sensitivity of soft clays in-situ
  • Detailed field investigation of undrained shear strength and sensitivity of soft and medium stiff clays
  • Hand operated from 0 to 30 metres depth
  • 2 vane sizes
    0-60kPa and 0-100kPa measurement ranges
  • Highly accurate results, suitable for earth fill foundation and embankment design

The H-10 is a fully protected, pressure push-in, field vane instrument. No rod-soil friction is possible due to the tube-protected rods. The protection shoe not only protects the vane but also cleans it automatically before each measurement, which is particularly useful in stratified, sandy, stony and marine sediment clays.

Installation

Pressure push-in, no hammering. By hand with ground-anchored jacking system or with a hydraulic drilling rig.
Instrument: Gear driven, accuracy of torque reading ±0.5% of range.
Measurement range: 0-060kPa (0-6 T/m²) and 0-100kPa (0-10 T/m²)
