In the technical scheme of this application, expansion section and interior expansion section have been increased, when the geotome was used, screw into the threaded rod to inside barrel lower extreme spiral, when the threaded rod reached interior expansion section inner wall, because the internal diameter of interior expansion section is less than the external diameter of threaded rod, so interior expansion section external diameter grow under the extrusion effect of threaded rod, thereby the external diameter that makes interior expansion section is greater than the internal diameter of outside barrel, just so make interior expansion section card in expansion section, make inside barrel can fix in the longitudinal position of outside barrel, thereby make at geotome tunneling in-process, inside barrel need not be held by hand fixedly, convenient tunneling.
Optimally, the geological survey geotome, wherein the lower end of the outer cylinder body is provided with the necking section I.
Optimally, the geological survey geotome, wherein the lower end of the inner cylinder body is provided with a necking section II.
The arrangement of the necking section I and the necking section II enables the lower end of the soil sampler to be convenient to tunnel, and resistance in the tunneling process is reduced. However, if the wall thickness of the thinnest part of the necking section I and the necking section II is too thin, the rolling edge can be caused in the tunneling process to influence the tunneling process, so that the wall thickness of the thinnest part of the necking section I and the necking section II is better when the wall thickness is 2 mm.
Optimally, the geological survey geotome is characterized in that scales are arranged on the inner cylinder body and the outer cylinder body.
Preferably, the geological survey geotome is characterized in that a positioning protrusion is arranged on the outer wall of the inner cylinder, a strip-shaped positioning groove is formed in the inner wall of the outer cylinder, and the positioning protrusion and the positioning groove are matched.
The positioning bulge and the positioning groove are arranged, so that the inner cylinder body is convenient to position in the outer cylinder body, and in the tunneling process, the inner cylinder body and the outer cylinder body are prevented from rotating relatively.
The invention has the advantages that the invention can overcome the defects of the prior art and has reasonable and novel structural design. The geotome of this application is in the tunneling in-process, and inside barrel is fixed in the position of outside barrel, can not take place relative rotation and relative slip, can not need hand at the tunneling in-process, facilitates the use.
