Soil
Vane borer pocket vane tester
14.08 Field inspection vane borer, standard set for measurement up to 160 kPa (16 t/m2) and
a depth of 10 m
The robust field inspection vane borer is a somewhat heavier tool for measuring the shear strength in the field. Without pre-drilling a hole the vane can be pushed or hammered into the soil. If the soil is too hard, then it is recommended to pre-drill a hole. Measurements can be executed up to a depth of 10 meter and a shear strength can be measured to a maximum of up to 160 kPa
(16 t/m2). Because of its unique 180° slip coupling this type of vane tester can be used to measure the friction and the shear strength of the rods direct and separately.
14.10 Pocket vane tester for measurement up to 250 kPa (2.5 kg/cm2)
The pocket vane tester is a shear strength measuring tool that is used in profile pits or on the
surface. The small, practical format also makes the tool very suitable for testing on soil samples.
The short period of time the test takes allows for several measurements in the same soil or layer which in turn allows for the calculation of an average value. The shear strength can be read from a scale fitted with dragging pointer. Conditions for correct measurement are: a flat surface, care placing of the vanes in the soil and turning the meter with a constant (relaxed) speed.
