Problems solved by technology

[0005] The object of the present invention is to provide a geographical underwater sediment sampler and method, which solve the aforementioned four problems at the same time, one is to keep the soil layers at different depths as they are, and the other is to solve the problem of bottom bearing in a very simple way. The problem of the support ensures that the sample does not fall. Thirdly, the sampling is deep enough, and the unfavorable method of piston pushing out is completely abandoned. This method is the original creation of this application and has no prior art inspiration

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 ...

Abstract

A geographical bottom sediment sampler, characterized in that it comprises a frame body (1), a pocket bottom (2), a sampling part (3), and a handle part (4); a geographical bottom sediment sampling method, which utilizes Geographic bottom sediment sampler to carry out, which includes preparation step, bottoming step, raising step, sampling step.

Description

technical field [0001] The invention relates to the technical field of geographical bottom sediment sampling, in particular to a geographical bottom sediment sampler and a sampling method. Background technique [0002] Tidal flat swamp is a unique wetland type, located in the area where land interacts with water bodies such as oceans, rivers and lakes, and has great geographical research value. Tidal flat marshes are rich in organic matter and are also one of the most sensitive ecosystems to global changes and human activities. The biogeochemical process of tidal flat swamp sediments is a hot spot of common concern in physical geography, ecology, soil science and environmental science, and the study of tidal flat swamp sediments must be premised on obtaining a large number of accurate and reliable sediment samples. [0003] The tidal flat marshes have been in a state of intermittent flooding for a long time, so that the sediments are mostly soft plastic silt. At the same t...
