In-Situ Vane Shear Test Apparatus
Product Code : EL-STLE-10399
Quick Answer: The In-Situ Vane Shear Test Apparatus is used to conduct the in-situ vane shear test from the bottom of a borehole in saturated cohesive soil deposits, to determine their in-place shearing resistance. It comprises a torque applicator assembly (2000 kg/cm2 capacity) with a split proving ring and dial gauge mounted on a base, quick-coupling rods, dummy rods, and vanes of 37.5mm and 50.0mm diameter, and conforms to the IS4434-1967 standard.
The apparatus is designed for conducting the 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, marked in degrees, holds a torque ring and is geared to a crank; the torque ring is a split ring that 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 kgs/cm2 is supplied. For registering the rotations of the vane, a detachable stand is provided to anchor the instrument, and an attachment to securely hold the string of rods is provided. A pointer is also provided.
The equipment comprises the following:
Torque applicator assembly, capacity 2000kg/cm2, with split proving ring and dial gauge 0.002 x 5mm, complete with stand.
Rods, quick coupling type, 1 mtr. long: 1 no.
Rods, quick coupling type, 1 1/2 mtr. long: 1 no.
