Product Description
Dual Variable Head Automatic Osmotic Pressure Meter
(Model:LFTD1406;Manufacturer:LIFETIME)
LFTD1406 dual variable head automatic osmotic pressure meter is an advanced laboratory geotechnical test instrument. It is mainly used to accurately and automatically test the permeability and deformation characteristics of viscous soils and silty soils under certain pressure conditions in the laboratory.Variable head permeability test, standard one dimensional consolidation test and osmotic pressure test can be completed.
The instrument is Standard viscous soil variable head permeability test can be carried out, that is, the laboratory simulation of soil permeability process, through Darcy's law to study the permeability of soil under one-dimensional permeability condition, in order to evaluate the anti-permeability safety performance of soil in foundation pit, slope, earth and rockfill dam and other projects.
Osmotic pressure test
Seepage pressure test can be carried out, that is, under the condition of soil under stable consolidation pressure, pressure head can be applied to the soil sample to improve the test efficiency, and the coupling state of soil mechanics and hydraulics in actual working conditions can be simulated to study the permeability characteristics of soil under pressure.
Technical characteristics
During the permeation test, the dead weight stress or different consolidation pressure can be applied to the soil sample
The leakage between the ring cutter and the soil sample caused by disturbance can be avoided
The osmotic pressure can be increased, thus greatly improving the test effectiveness
The consolidation test can be carried out to determine the consolidation coefficient and establish the correlation study between the consolidation coefficient and the permeability coefficient
The initial head gradient of soil can be studied
If necessary, conventional consolidation test and determination of pre-consolidation pressure of shallow soil can be carried out
During the test, the water head change is measured automatically by computer and the data is collected and processed
Configuration parameters
Mature and stable control system, direct closed-loop control of axial force and axial displacement
The diameter of the soil sample is 61.8mm and the area of the soil sample is 30 cm2
Soil sample height: 40mm (20mm optional)
Consolidation pressure is 0 ~ 1000kPa
Osmotic pressure is 0 ~ 200kPa
The maximum compression of soil sample is 10mm
The variation range of water level measured by pressure difference sensor is 0 ~ 40cm, and the accuracy is 1cm
The area of variable head break is 0.785cm2
