VJ Tech - Bishop Ring Shear Pro System
FromVJ Tech Limited
In his type of Ring Shear apparatus, the ring-shaped soil specimen is enclosed inside a rigid set of discs (external and internal). The maximum height of the specimen can reach 20 mm, which makes it less sensitive to the presence of large particles in the soil and any friction developed against the confining rings is measured. An adjustable gap is created between the upper and lower soil mass, on the sliding surface, to minimise the friction between the fixed upper portion of the annular specimen and the rotating lower part. Soil-soil and soil-steel interface tests can be conducted with the Bishop Ring Shear apparatus.
