Description

during the erection of alluvial structures, it is necessary to control the layout of the fractions in parts of the washed structure. This control of the washing of the structures under the water is difficult to implement, as until now there are no instruments that allow a quick sampling of the soil at the intended place of the structure washed in the water.

The proposed grab subsoil allows one to take soil samples with sufficient rapidity from a structure washed in water to determine the grain size distribution.

The drawing shows two side views of the proposed submersible, and in FIG. 1, the solid earth line is shown in the open position, with a dotted line in the closed position.

The proposed ground lug consists of two spherical parts 1, 2, forming a cavity 3 for taking

soil hinged to disk 4. When sampling, disk 4 rests on the ground and limits the sample from above. The spherical parts 1, 2 are driven by levers 5, 6 when pressed from above and, closer, cut out a sample of the soil under the disk 4. The proposed grab submersible allows you to take samples of the soil at precisely designated points with very little disruption of the structure.

The subject matter of the invention.

Grabber submersible for sampling of the soil, consisting of two articulated spherical parts, characterized in that the spherical parts 1 and 2, forming a cavity for taking the soil, are hinged on the disk 4, which is supported during the sampling on the soil and limitations on top of the sample taken.
