| 成果简介 | NOVELTY - Invention relates to gas sampling means. Disclosed is a drill for subsoil air sampling with a built-in ground water level indicator, consisting of a housing with air intake holes and a drilling mechanism, at that, the drilling mechanism is made in the form of a generatrix of the Archimedean screw of a steel tape of the same width, evenly along the spiral, butt welded to the drill body along its entire length, at that, the drill body is made in the form of a hollow pipe, in the wall of which there are holes arranged along the spiral under the steel tape of the Archimedean screw at equal intervals with pitch within 1/4-1/3 of the pipe circumference, and the two lower holes are located 5-7 cm higher than the end of the pipe at the same level, opposite each other, wherein a sealing packer with a hole connected to the gas discharge pipe is installed inside the hollow pipe, and above the lower two said holes there are elements of the electric circuit of the level indicator, consisting of a central contact isolated from the wall of the hollow pipe, a DC power supply and a light-emitting diode installed at the upper end of the hollow pipe of the drill, besides, a detachable ram is attached to the lower end of the hollow pipe, the protruding part of which is made in the form of sharp petals. USE - Sampling. ADVANTAGE - Invention provides air sampling from a given depth of soil of different density and increased reliability of operation in conditions of high ground water level. 1 cl, 2 dwg |
