FIELD: construction, road engineering. ^ SUBSTANCE: invention relates to construction and may be used to monitor and investigate a core sample from wells and structures. The sampling device comprises a sampler, where one end of a rope is fixed, and the other end is fixed on the sampler. At the same time a device of sampler retention is made of a torus, which is covered on top with an adhered industrial rubber fabric, which serves as a roof. The surface of the torus and roof forms a tight cavity, where vacuum is pulled as the torus is blown. Atmospheric pressure pushes the shell and the cover and presses it to road surface. When the sampler is pressed into the earth bed, it stops against the rope connected to the sampler retention device. ^ EFFECT: sampler retention on the road surface. ^ 2 dwg |
