FIELD: construction; mining.
SUBSTANCE: invention can be used to evaluate parameters of strength of soil and dump rocks. Device for determination of parameters of strength of soils and dump rocks includes a thrust beam, a box with a rock prism, a die installed on the rock prism, a jack installed between the beam and the die, a ball cage installed between the jack and the thrust beam. It is equipped with two trolleys connected by means of rods and turnbuckles with side surfaces of the box and a thrust beam. Device is also equipped with a plate installed with possibility of horizontal movement and rigidly connected to the box by means of tie rods and tension dynamometers; at that, the plate is equipped with two horizontally installed jacks.
EFFECT: increasing the efficiency and reliability of determining the strength parameters of soils and dump rocks in natural conditions.
