In specific implementation, exploration sites selected first take the rotary sleeve pipe fixed and counterclockwise of sand inner tube 2 using preceding holding
1 opens wide vane disk, outer tube 1 and sand inner tube 2 is taken to keep moving synchronously in tunneling process, when taking sand inner tube 2 to fill sandy soil
Fixation takes sand inner tube 2 after undisturbed, and rotating clockwise outer tube 1 screws out vane piece 6, forms closure vane disk and by sandy soil
Undisturbed, which is enclosed in, to be taken in sand inner tube, so as to obtain sandy soil undisturbed.
The present invention is suitable for Geological Engineering, Geotechnical Engineering field, can be widely applied for all kinds of sandy soil undisturbeds
Quick sampling.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is that vane dish structure of the invention splits schematic diagram；
Fig. 3 is that vane disk of the invention is closed (A), opens wide (B) state diagram.
In figure: 1 outer tube, 2 take sand inner tube, and 3 cut native cutting ring, 4 horizontal ball bearings, disk on 5 vanes, 51 guide grooves, 6 rotations
Blade, 61 guider screws, 62 fixing screws, 63 cutting edges, 7 vane lower walls, 71 fixed points.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in Figure 1, the present invention includes outer tube 1, takes sand inner tube 2, cuts native cutting ring 3 and vane disk；Outer tube 1 and cut soil
