About Universal Triaxial Cell

Universal Triaxial Cell

The cell assembly consists of a base with provision for fitting four valves. One valve connects to a peripheral hole on the base and serves as water inlet from the lateral pressure assembly. The other valve is connected to peripheral hole which is tapped to receive the nuts on the plastic tube from top platen

Remaining two valves are connected to the bottom of the specimen through the hole in the bottom pedestal. The top drainage tube is provided with quick release adopters at both ends. Four clamping pipes, top cap , bottom ring and Perspex cylinder form an integral unit. The cylinder base has four threaded holes. Four tie rods that are sufficiently long to pass through clamping pipes and such that the threaded ends can engage with corresponding threaded holes in the base ring. A loading plunger moves through a lapped gland bush integral with the loading pump. The plunger is ground and the clearance provided between the bush and the plunger is so little that with a thin layer of oil on top of water in the triaxial cell, the cell can stand fluid pressures up to 10kgf/cm2 for normal duration tests in practice.

This plunger has a recessed end at the top and a spherical end at the bottom. The bottom end sits in the recess on the loading pad. The top cap has an air vent for allowing the air to pass out as the liquid enters the cell and is closed by the air vent plug. Another inlet with plug provided on the cell cap can be used to introduce a layer of oil on top of the water in the cell for effective sealing the gland for long duration tests. All the joints. Valves, valves and seal of the plunger are leak checked at 10 kgf / cm2. A stem and stem rod are provided to arrest upward movement of plunger and to mount the strain gauge. Complete with the following.

Brass pedestal for 38mm, 50mm, 75mm & 100mm dia specimen.
Perspex loading pads for 38mm, 50mm, 75mm, 100mm specimen.

Robust Design and Reliable Materials

The triaxial cell is constructed from corrosion-resistant stainless steel and features an anodized aluminum/brass base plate for durability and longevity. Interchangeable parts add flexibility, while a precision needle valve and O-ring seals guarantee sample integrity during soil mechanics tests. Its semi-automatic bench-top build is ideal for repeated laboratory usage.

Enhanced Measurement and Safety Features

Equipped with a burette system, the cell allows precise pore pressure readings. The over-pressure relief valve and perspex observation window add safety and practical monitoring during tests. This units analog and optional digital display options ensure clarity, and the entire process is supported with manual and pneumatic controls.

Conformance and Application Versatility

Compliant with ASTM D2850 and BS 1377, the Universal Triaxial Cell accommodates diverse soil specimen sizes. With a confining pressure range up to 1700 kPa and cell capacity up to 7000 kPa, it covers a wide array of geotechnical investigations. Standard 230V AC, 50Hz power supply ensures compatibility in Indian labs and similar global settings.

FAQs of Universal Triaxial Cell:

Q: How is the Universal Triaxial Cell used in soil testing applications?

A: The triaxial cell is utilized to determine the mechanical properties and strength characteristics of soil samples under controlled laboratory conditions. It allows for the application of confining pressure and accurate measurement of pore pressure, making it ideal for geotechnical engineering and academic research.

Q: What specimen sizes can be tested with this equipment?

A: This cell supports single specimens with diameters of 38, 50, or 75 mm and heights between 76 and 150 mm, offering versatility for various soil sample dimensions required in geotechnical investigations.

Q: When should I use the manual versus the pneumatic control mode?

A: Manual control is preferred for simple setups and greater operator involvement, while pneumatic mode facilitates consistent pressure application and ease in repetitive testing. Selecting the mode depends on the desired automation and test precision requirements.

Q: Where is the Universal Triaxial Cell typically mounted during use?

A: Designed as a bench-top unit, the cell is installed on a sturdy laboratory table or dedicated testing station, ensuring stability during operation and convenient access for researchers and technicians.

Q: What process is involved in measuring pore pressure using this equipment?

A: The cell features a burette system attached to the chamber, allowing users to precisely monitor changes in pore water pressure during triaxial testing, which is critical for analyzing soil behavior under stress.

Q: How does the over-pressure relief valve enhance operational safety?

A: The integrated over-pressure relief valve automatically mitigates excess pressure conditions, preventing chamber damage and safeguarding both the equipment and laboratory personnel during high-pressure testing procedures.

Q: What are the main benefits of using this triaxial cell for soil analysis?

A: This equipment provides high accuracy (1% full scale), reliable sealing, precise pressure control, and exceptional durability, making it suitable for repeated laboratory use. It conforms to international standards, supports multiple specimen sizes, and improves efficiency in geotechnical testing projects.
