FIELD: construction.
SUBSTANCE: method to test soils with static and dynamic load consists in the fact that soil testing is done in steps or continuously with the specified speed of screw stamp movement from the specified load stage with account of deformation due to bend of hollow rod segments. At the same time the device for realisation of the specified method comprises a screw stamp, a hollow pump rod made of segments, a loading accessory, measurement accessories, made in the form of a linear displacement sensor, and a loading mechanism. Besides, inside each segment of the hollow rod there is a sensor unit, comprising an inclination sensor with digital output and a transceiver. Sensor units are connected into a single sensor network and send information along radio frequency to each other and to a remote computer.
EFFECT: higher accuracy of measurements of screw stamp subsidence, expansion of functional capabilities and higher efficiency of soil testing in field conditions.
