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 , a geographical underwater sediment sampler provided by the present invention is characterized in that it includes a frame body 1, a pocket bottom 2, a sampling portion 3, and a handle portion 4.

[0024]The frame body is a hollow cuboid surrounded by steel plates on the first surface 11, the second surface 12, the third surface 13 and the fourth surface 14, and the cross section is rectangular; the third surface 13 faces forward, and the sampling part 3 is located at the on three surfaces. Here, a sampler with a rectangular cross-section is still used, which is suitable for sampling in tidal flats and other places. In order to be more durable, the frame can be treated with anti-corrosion, but it cannot be painted.

[0025] The pocket bottom 2 includes a first groove 21, an insert 22, a bottom groove 23, and a second groove 24. The first groove is located on the inner side of the first surface and extends from the uppermost edge of the first surface t...

Embodiment 2

[0030] A kind of geographic bottom sediment sampling method, it utilizes as aforementioned geographical bottom sediment sampler to carry out, it is characterized in that: (1) preparatory step: the overall cleaning of sampler is dried, and cladding sheet is installed, Select the sampling position, insert the frame vertically into the sampling position, and push the buckle part of the handle against any upper edge of the frame until the distance between the horizontal marking line and the ground of the sampling place is within 1cm; this can basically ensure sufficient sampling The depth of the sample, preferably, for example, the horizontal marking line is parallel to the ground at the sampling place; (2) bottom-up step: insert the insert into the first groove until the 1.2m marking line on it enters the first groove, if If this position cannot be inserted, go back to step (1) and replace the sampling position; if the 1.2m mark line enters the first slot, go to step (3), where th...

Abstract

The geographical underwater sediment sampler is characterized by comprising a frame body (1), a bag bottom part (2), a sampling part (3) and a handle part (4), the invention relates to a geographical underwater sediment sampling method, which is carried out by utilizing a geographical underwater sediment sampler and comprises a preparation step, a bottom holding step, a lifting step and a sampling step.

Description

technical field [0001] The invention relates to the technical field of geographic bottom sediment sampling, in particular to a geographic bottom sediment sampler and a sampling method. Background technique [0002] Tidal flat swamp is a unique type of wetland, which is located in the zone where land interacts with water bodies such as oceans, rivers and lakes, and has great geographical research value. Tidal flat swamps 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 marsh sediments is a common concern of physical geography, ecology, soil science and environmental science, and the study of tidal marsh sediments must obtain a large number of accurate and reliable sediment samples. [0003] Tidal flat swamps have been in a state of intermittent flooding for a long time, making the sediments mostly soft plastic silt. At the same time, there are a large number of roots and ...
