Description

In the proposed device for the extraction of samples, underwater of the soil, related to the type of devices, divided by partitions into several compartments, the partitions are made opening,.

Pa drawing FIG. 1 shows a general view of the device; FIG. 2-vertical times of the instrument; FIG. 3 - front view of the device; FIG. 4 and 5 is a side view of the device with a partial section in various positions of work; FIG. b - a detail of the device.

The device is a copper box divided by partitions into several compartments; the partitions with one end are attached on the hinges to the wide wall of the box, the other free end lies in the recess of the second wide wall. A collar is attached to the upper part of the box, into which a wooden rail is inserted to the appropriate depth. After the rail is attached, the device is lowered into water, which

pressing on the movable partitions causes them to lift (Fig. 5). In this position, water passes freely through the device, which, when it reaches the ground, is immersed in it and filled with it, depending on the thickness of the floor or in its entirety, or in any part of it. When lifting the device, the ground, having touched the projecting parts of the partitions, forces them to fall into place and loses the opportunity to fall out of the box. Pulling out the device and opening the side door, it is easy to determine, by the number of occupied compartments, the thickness of the soil layer.

The subject matter of the invention.

A device for excavating soil samples, forming from a pipe divided by partitions into several sections, characterized in that the partitions with one ends are pivotally attached to the wall of the pipe, while the other ends freely lie on the protrusions of the wall in order to extract the soil below
