Triaxial Shear
Triaxial Cells
UMI Triaxial Cells confirm to the requirements of IS:2720 (Part 11) and (Part 12) and are made from corrosion resistant material. Particular attention is paid to the quality of the finish between the stainless steel plunger and the bushing. The cell cylinders ar e made from acrylic plastic material and those for use upto 20 bar (20 kg/cm2) are usually reinforced by bands. Each cell has four take-off positions, drilled in the base, for the following purposes :
1. Cell pressure
2. Pore water pressure
3. Drainage or back pressure All valves are 'no-volume change' type.
UMI – 136-1
Triaxial cell
For testing specimens of size 38 mm dia x 76 mm long and 50 mm dia x 100 mm long.Perspex (Acrylic Plastic) chamber with an anvil and a loading plunger. The cell is easily split by releasing four tie rods. It is leakproof upto 10 bar (10 kg/cm2) fluid pressure. Cells can be made to withstand the pressure of 20 bar, on request. An oil plug and air vent are provided for introducing a thin layer of oil over water. This provides an effective sealing at the plunger for long duration tests. The cell if fitted with four ball valves of no-volume change type, at the base.
