Hydraulic Consolidation Cells

Hydraulic consolidation cell 26-WF0345
Associated with pressure system, de-airng weter and measuring system, the  hydraulic consolidation cell is used to determine the magnitudes an rates of consolidation of soil specimen by hydraulic pressure allowing to obtain additional information form the soil smaple compered to the most common consolidation cells.

Hydraulic Consolidation Cell

Used for hydraulic consolidation test on saturated soil sample.

Standards BS 1377:6

Hydraulic consolidation cell 26-WF0345
Description

 

The Hydrocon hydraulic consolidation cell is the basic part of the apparatus used for the determination of the magnitude and rates of consolidation of soil specimens of relatively low permeability using hydraulically loaded apparatus. This procedure overcomes the complexity usually associated with hydraulic oedometers and allows more information to be gathered from the soil sample. Pore water pressure is measured using a pressure transducer and vertical settlement using a linear strain transducer (or, as economical alternative, a dial gauge). As the Hydrocon is a confined consolidation system, it is possible to measure both pore and back pressure during testing. In addition it is also possible to make accurate permeability measurement generating a vertical flux of water through the sample.

The complete test configuration includes: Hydrocon cell, Water pressure system, Water de-airing system and measuring system (manual or electronic with Geodatalog data acquisition system )

For a complete test configuration (pressure system, pore pressure, displacment transducer, volume change and other accessoreis) see the related products and ask for the cooperation of our specialist.

Hydraulic Consolidation Cell for Unsatureted Samples

Used for hydraulic consolidation test on unsaturated soil sample.

Hydrocon for hydraulic consolidation 26-WF0346 with fitted linear transducer
Description
 
The Hydrocon SWCC consolidation apparatus is used to determine the magnitude and rate of settlement and pressure of unsaturated soil specimens. Because of the low permeability of some materials, performing a drying and wetting stage can take several weeks. The Hydrocon SWCC cell is a flexible soil testing apparatus capable of applying uniaxial pressures of up to 3500 kPa to a 100 mm diameter specimen. Its base is fitted with a High Air Entry Stone (HAES) which enables a soil/water characteristic suction curve to be obtained. This type of stone allows water to pass through but not air so that the soil matrix potential can be controlled at various values: 1,5 and 15 bar. During a test it is possible to load the soil specimen in such a way that the overburden pressure in the field is recreated, whilst measuring the chamber and pore water pressure using a pressure transducer and the vertical settlement using a linear strain transducer.
As the Hydrocon SWCC is a confined consolidation system, it is possible to measure both pore and back pressure during testing and to make accurate permeability measurements.

The complete test configuration includes: Hydrocon cell (SWCC) , Water and air pressure system, Water de-airing system and electronic measuring system with Geodatalog data acquisition system.
