FIELD: construction.
SUBSTANCE: device for testing the compressibility of soil comprises the cylindrical body, perforated plunger and porous bottom. The instrument also includes the insert made of elastic material, provided with displacement sensors disposed between the case and sample under test. Insert permits the soil sample to expand under the action of load in transverse direction, besides the simultaneous compression of the soil sample and flexible insert is provided.
EFFECT: improving the accuracy of the results of measurements of the deformation module and coefficient of transverse deformations, simplifying the design of the instrument.
