The geotextile-bentonite cushion is a finished waterproof soil mat with excellent water-retention performance. The Geotextile-Bentonite Cushion Permeameter is used to determine the permeability coefficient of bentonite waterproof blankets under specified pressure and time conditions. Under a given hydraulic gradient, a small seepage occurs in the bentonite blanket. By measuring the seepage volume through the sample and the sample thickness over a specified period under a given pressure difference, the permeability coefficient can be calculated.
Features
(1)Uses a 1+2 configuration, offering a single main testing station with two additional auxiliary stations.
(2)The workbench is made of stainless steel, providing a clean appearance, good water resistance, and rust prevention.
(3)Tests are performed using pneumatic loading, requiring no electricity, ensuring safety and reliability.
(4)Equipped with imported high-precision pressure regulators, ensuring accurate and stable pressure control to meet test requirements.
(5)The loading circuit is designed reasonably, and air valve adjustments are simple and convenient.
(6)Improved measurement accuracy, with seepage volume precision up to 0.05 ml.
(7)Integrated vacuum system facilitates vacuuming during sample preparation and testing.
(8)Includes a negative pressure degassing device, ensuring water entering the sample is degassed, yielding more accurate test results.
(9)Test chambers are movable, providing greater operational flexibility.
(10)Uses a three-way valve as the main component, simplifying operation.
(11)Reserved interface for automatic testing, allowing an automatic testing device to record pressure, measure permeability, and display results automatically.
