TRIAXIAL CELL (STATIONARY BUSHING): For 38 mm dia specimen
AS PER IS: 2720 (Part - XII)
Introduction: TRIAXIAL CELL:
-
Total stresses when measured in a triaxial cell are more complex in their nature. Numurous parameters may be measured inluding back, pressure, pore water pressure and volume change.
-
From these values various engineering properties can be calculated.
-
Triaxial cell is used to apply total stress.
-
The sample is subjected to an alround confining pressure. Load is then applied through piston of triaxial cell on a pressure pad on the top of the specimen.
-
In a triaxial cell, sample is confined in a rubber membrane. Triaxial Cells are manufactured from carefully selected material.
-
The cells are manufactured to accommodate different sizes of specimen. Universal Triaxial Cell accommodates samples of diameters 38 mm to 100 mm.
General Description and Specifications:
-
The cell is useful for testing 38 mm dia x 76 mm high soil specimen.
-
Transparent Perspex chamber with anvil and loading plunger.
-
The cell is easily opened by releasing four nuts of the tie rods.
-
It is leak proof up to 10 kg/cm sq. fluid pressure.
-
An oil plug which can also be used as an air vent is provided for introducing a thin layer of oil over water.
-
This provides effective sealing at the plunger for long duration tests.
-
The cell is fitted with four sleeve packed valves of no volume change type on the base.
-
These valves are used for cell pressure, pore water pressure, drain age or back pressure.
-
The loading plunger of the cell has a dial gauge rest.
-
Loading pad made of Perspex for 38 mm dia specimens.
-
Pair of plain discs made of Perspex 38 mm dia 6 mm thick.
-
Pair of porous stones 38 mm dia x 6 mm thick.
-
Split sand former for 38 mm dia specimen.
-
Sheath stretcher for 38 mm dia specimen.
-
One dozen rubber sheaths for 38 mm dia samples.
-
For synthetic rubber ’O’ rings for 38 mm dia specimen.
-
One plastic drainage tube.
OPTIONAL:
UNIVERSAL TRIAXIAL CELL (STATIONARY BUSHING): Suitable for testing 38 mm, 50 mm, 75 mm and 100 mm. diameter specimens.
