FIELD: construction.
SUBSTANCE: instrument comprises a body with a porous bottom, a ring with soil, a loading accessory of a piston and measurement accessories for measurement of pore and side pressure. The instrument is made of four hydraulically and electrically interconnected parts: a press, an odometer, a unit of signals amplification and conversion from sensors into a digital form with a computer and an interface and a backpressure unit.
EFFECT: increased accuracy of soil pore and side pressure measurement, expansion of investigation range and increased efficiency of tests.
