Application:

This test method can replace sand replacement method and irrigation methods, test speed, high precision and easy operation.
* Uses
Balloon-type volumetric measuring instrument is a determination of soil density test instrument for determining the density of the field maximum particle size of less than 20mm of soil.
Applicable Standard: "The railway engineering soil test procedures" (TB 10102-2004).
* working principle
Balloon-type volume analyzer is based on physics of Boyle (Boyle) Law design; the test, with a certain pressure, pushes the piston to medium (air) to be placed within the cylinder test pit airbag transferred, so that the air bag inflates close to the inner wall of the test pit; a data recording device for displaying measurement, calculation test pit volume.
