FIELD: construction.

SUBSTANCE: soil bore-sampler comprises a cylindrical rod, at the upper end of which a crank with a handle is fixed, and at the lower end - a cup with cutters and a supporting point with pins. A retaining bushing with the possibility of rotation, a pipe with holes of a predetermined pitch with the possibility of moving and fixing, and a restricting assembly are mounted on the cylindrical rod. A guide sleeve, clamps for the pins, a level, and a bracket with a horseshoe-shaped stop are additionally mounted on the supporting point, the distance between the supporting point and the horseshoe-shaped stop exceeding the height of the cup smaller than the guide sleeve.

EFFECT: reducing the labour intensity of soil sampling from different layers in depth, with the possibility of estimating the soil composition density, providing the design simplicity.
