In-situ Vane Shear Test Apparatus
Ref. Standard IS:4434
This 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. 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 has a section cut from it and deforms as torque is applied and the deformation is indicated by a dial gauge. 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. A calibration curve to convert the dial gauge readings to kg-cm of torque is also supplied. The outfit comprises the following:
- Torque Applicator Assembly, capacity 2,000 kg-cm.
