Embodiment 1
[0023] see Figure 1-4 , The present invention provides a geographical bottom sediment sampler, which is characterized in that it comprises a frame body 1 , a pocket bottom 2 , a sampling part 3 , and a handle part 4 .
[0024]The frame body is a hollow cuboid surrounded by the steel plates of the first surface 11, the second surface 12, the third surface 13 and the fourth surface 14, and the cross section is a rectangle; the third surface 13 faces forward, and the sampling part 3 is located in the on three surfaces. Here is a sampler with a rectangular cross-section, which is suitable for sampling in tidal flats and other places. For more durability, the frame can be treated with anti-corrosion, but not painted.
[0025] The pocket bottom 2 includes a first groove 21, an insert piece 22, a bottom groove 23, and a second groove 24. The first groove is located inside the first surface and extends from the uppermost edge of the first surface to contact with the bottom groove. ...
Embodiment 2
[0030] A geographical bottom sediment sampling method, which utilizes the aforementioned geographical bottom sediment sampler to carry out, and is characterized in that: (1) preparation step: cleaning and drying the sampler as a whole, and installing the steel-clad sheet, Select the sampling position, insert the frame vertically into the sampling position, and use the reverse button of the handle to top any upper edge of the frame until the gap between the horizontal marking line and the ground at the sampling site is within 1cm; this can basically ensure enough sampling. The depth of the sample, preferably, for example, the horizontal marking line is parallel to the ground at the sampling site; (2) the bottom step: insert the insert into the first groove until the 1.2m marking line on it enters the first groove, if If it cannot be inserted into this position, go back to step (1) and change the sampling position; if the 1.2m mark lines all enter the first slot, then go to step ...
