Soft Inclusion Stress Cells VW Model 4360

Soft Inclusion Stress Cells VW Model 4360

The Model 4360 Vibrating Wire Soft Inclusion Stress Cells (SISC) are larger versions of the Model 4300 Borehole S

Description

The Model 4360 Vibrating Wire Soft Inclusion Stress Cells (SISC) are larger versions of the Model 4300 Borehole Stressmeters. The SISC is pre-loaded by wedging it into a large size diamond drill hole using an integral screw mechanism or hydraulic piston and can be set to measure both tensile and/or compression stress changes. It has been used successfully in 152 mm diameter overcoring holes (drilled to measure in situ stresses) to measure Aggregate/Alkali Reactions (AAR) in concrete dams
