FIELD VANE SHEAR TEST(FVST)

FIELD VANE SHEAR TEST(FVST)

Model 16-T0174

This is the most commonly used method for measuring the undrained shear strength of soft to stiff clays.

For this reason, a preliminary investigation of soft clays with a hand-held vane tester is both economic

and fully relevant. It also has good repeatability and is quick in providing valuable information for the planning of more detailed surveys.

However, results with systematic errors can occur if the testing equipment used is inaccurate or unreliable. Such errors can result in high cost if they are incorporated in the fi nal design parameters. This hand-held vane tester is fully professinal instrument for preliminary FVST investigations.

Features

• Preliminary field investigation of undrained shear strenght of soft to stiff clays

• Quick and easy to use, low weight

• Direct manual boring down to 3 meters

• Measurement range from 0 to 200 kPa

• Delivered with calibration certifi cate

This instrument consist of three exchangeable vanes, extended by 0.5 m rods.

The instrument covers three ranges of measurement,0-50,0-100,0-200 kPa, depending on the size of vane used: 16 x 32 mm, 20 x 40 mm or 25.4 x 50.8 mm.

The peak value is determined by means of the scalering, which has to be turned back to zero position before each measurement. The instrument is sufficiently rugged to be used as a handle during penetration and retraction of the vane. To correct for the skin friction of the extension rods, dummy tests are performed with the rods only.

Total weight: 3.10 kg
