IN SITU VANE SHEAR TEST
As per IS: 4434 - 1967.
The apparatus is designed for conducting in situ vane shear test from the bottom of a bore hole in saturated cohesive deposits for determining their in place shearing resistance.
Specifications: The equipment consists of a torque applicator assembly mounted on a base. A gear wheel, which is marked in degrees, holds a torque ring and is geared to a crank. The torque ring is a split ring and deforms as torque is applied and the deformation is indicated by a dial gauge. A calibration Chart to convert dial gauge readings to torque force in kg.cm. is supplied. A pointer is provided for registering the rotation of the vane. A detachable stand is provided to anchor the instrument. An attachment to securely hold the string of rods is provided.
