About Pore Pressure Apparatus

Specification:

A Pore Pressure Apparatus with a 10 kg/cm capacity is a soil testing instrument used to measure pore water and air pressure in soil specimens during a triaxial test. Key specifications often include a pressure range of 0-10 kg/cm, a Bourdon or digital pressure gauge, a 50ml capacity burette for volume change measurement, a pressure pump, a null indicator, and a reservoir made of transparent acrylic or polycarbonate. The apparatus typically uses copper coils and has a complete stand assembly for wall mounting.

Key Components & Features

Pressure Gauge:

A Bourdon dial or digital type pressure gauge that is typically Bourdon-tube, with a 15cm diameter and a pressure range of 0-10 kg/cm.
Pressure Pump:

A screw-type pressure pump with a handwheel-operated piston and four sleeve-packed valves for fine adjustment of pressure.
Null Indicator:

A transparent Perspex device, often called a null indicator, to show the mercury level and indicate changes in the system.
Burette:

A 50ml burette, also known as a volume change indicator, used to measure volume changes in the soil specimen.
Manometer:

A glass U-tube manometer for measuring low positive pore pressures and negative pore measures.
Pressure Reservoir:

A water reservoir made of transparent acrylic or polycarbonate with a capacity of approximately 250-500 ml.
Leakage Tested:

The unit is tested against leaks up to its maximum capacity of 10 kg/cm.
Stand Assembly:

A complete stand assembly to hold the apparatus and support the components.

Purpose

This apparatus is crucial in soil mechanics for measuring pore air and pore water pressures in soil samples during consolidation and triaxial compression tests.

Vendors

The apparatus is available from various manufacturers and suppliers, including Zeal International, Shambhavi Impex, and Aimil Ltd.

Precision Measurement of Soil Pore Pressure

This apparatus provides high accuracy (0.05 kg/cm2) and rapid response time (<1 second) for measuring pore water pressure in soils. The analog/dial gauge allows for clear display and easy monitoring. Adaptable for both 38 mm and 100 mm diameter specimens, it supports a broad measuring range of 0-10 kg/cm2, making it suitable for detailed soil analysis in laboratory settings.

Robust Construction and User-Centric Features

Engineered with corrosion-resistant materials, the apparatus is highly durable and built for frequent usage. Users benefit from its robust frame, simple maintenance requirements, and the convenience of a bench-top, manual control design. Safety is enhanced through a non-return valve and overpressure protection, while flexible tubing, connectors, and calibration certification provide everything necessary for reliable operation.

FAQ's of Pore Pressure Apparatus:

Q: How is pore water pressure measured with this apparatus?

A: Pore water pressure is measured by placing a soil specimen (either 38 mm or 100 mm in diameter) in the cell, filling it with de-aired water, and using the analog Bourdon-type pressure gauge to monitor pressure changes during testing. The response time is less than one second, ensuring immediate pressure readings.

Q: What material options are available for the cell body, and how do they benefit users?

A: Users can choose between stainless steel and acrylic cell bodies. Stainless steel offers excellent corrosion resistance and robustness, suitable for high-frequency or harsh lab conditions. Acrylic provides easy visual inspection of the test specimen and water level during operation.

Q: When should the drainage valve and non-return valve be used during testing?

A: The drainage valve is utilized to remove water from the cell before or after testing, ensuring proper sample preparation and cleanup. The non-return valve is a safety feature that prevents backflow and protects the system from accidental pressure surges, especially when adjusting test conditions.

Q: Where can this pore pressure apparatus be effectively used?

A: This apparatus is best suited for soil testing laboratories, educational institutions, and geotechnical research facilities in India and abroad. Its bench-top mounting and manual control feature provide flexibility for small to medium laboratory setups.

Q: What standards does this equipment comply with for soil testing applications?

A: The apparatus meets IS: 2720 (Part 30) and equivalent ASTM standards, ensuring reliable and standardized results for pore pressure measurement in soil specimens. It is suitable for professional, academic, and research use.

Q: What are the main benefits of using this apparatus in soil testing?

A: Key benefits include precise and repeatable measurements, user-friendly analog/dial display, robust and corrosion-resistant construction, comprehensive safety provisions, and complete accessory support for efficient operation and calibration.
