Detailed Description
The following description is of one embodiment with reference to the accompanying drawings.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, based on the embodiments of the invention, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the invention. Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in the following figures.
See fig. 1. The soil sample sampler described in this embodiment is specifically a tubular soil sample sampler with the simplest structure, and includes a second unit pipe 120 and at least one first unit pipe 110, where the lower end of the second unit pipe 120 is an insertion part capable of being inserted into soil; the first unit pipe 110 and the second unit pipe 120 are connected in series through a connecting hoop 130 to form a tubular soil sample sampler. The inner diameters of the first unit pipe 110 and the second unit pipe 120 are equal, and the outer diameters of the connecting hoop 130, the first unit pipe 110 and the second unit pipe 120 are equal, that is, the inner wall and the outer wall of the tubular soil sample sampler are ensured to be smooth surfaces, the surface resistance of the tubular soil sample sampler is reduced, and the tubular soil sample sampler is more convenient to be inserted into soil.
The length of the tubular soil sample collector is mainly determined by the number of the tube sections of the first unit tube 110, and the length of the tubular soil sample collector can be specifically set according to the requirement of the sampling depth. Meanwhile, the first unit pipe 110 also provides a function of a scale, i.e., according to the number of the first unit pipes 110 inserted into the soil layer, the depth of the tubular soil sample sampler inserted into the soil can be calculated, and of course, the height of the second unit pipe 120 cannot be ignored in the calculation. For example, the heights of the first unit pipe 110 and the second unit pipe 120 are set to be 10cm, the total length of the tubular soil sample sampler formed by connecting one section of the second unit pipe 120 and five sections of the first unit pipes 110 in series is 60cm, and the second unit pipe 120 is positioned at the lower part of the tubular soil sample sampler.
At the time of sampling, the depth of sampling of the soil sample may be determined according to the number of the first unit pipes 110 where the aerial parts are exposed or the number of the first unit pipes inserted into the soil. After the soil sample is obtained, the tubular soil sample sampler is pulled out with the soil sample, the connecting hoop 130 is disassembled, the first unit pipe 110 and the second unit pipe 120 are separated, the soil sample is disconnected at the joint of the first unit pipe 110 and the joint of the first unit pipe 110 and the second unit pipe 120, and the soil sample in the first unit pipe 110 and the second unit pipe 120 can be directly brought back to a laboratory for carrying out soil analysis work.
The obtained soil column is contacted with the unit pipe wall, and partial soil layer cross contamination exists, mainly substances in upper soil are brought into lower soil, but the contamination can be completely avoided in analysis operation work. In particular, the position of the soil sample in the first unit pipe 110, the second unit pipe 120 is fixed, and the soil of the soil cylinder surface (particularly, the side) is not mixed with the soil of the cylinder core. The soil quantity in the middle part or the core part of the soil sample column body can completely meet the requirement of the sample quantity of soil analysis.
On the other hand, the heights of the plurality of first unit pipes 110 may be the same or different. For example, the height specifications of the plurality of first unit pipes 110 may be 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, and other desired heights, and the corresponding first unit pipes 110 specifications and the corresponding installation order are selected according to the layer thickness of the soil profile so as to obtain the profile soil sample of each layer as much as possible. One method of sampling the profile soil sample is to dig a pit 1.5-2 meters long, 1 meter wide and about 1-2 meters deep, the specific depth being dependent on the site. One end of the cross-sectional pit is required to be sunk, and the cross-sectional pit is required to be vertically flattened to be used as a viewing surface. By observation, the color, texture, structure, compactness, root system distribution and other changes of the section can be clearly seen, the development process of the soil is deduced by referring to environmental factors, and the occurrence layers, such as a dead branch defoliation layer, a humus accumulation layer, a sediment layer, a matrix layer and the like, are specifically divided, and the depth of each layer (in centimeters) is measured by using a steel tape. By the aid of the treatment mode, it is difficult to ensure that soil with different layers is not polluted, and particularly when heavy metal soil samples are collected, exogenous heavy metal elements cannot be added into the soil samples due to sampling, so that accuracy and authenticity of analysis results are not affected. At a position close to the observation surface, sampling was performed by the soil sample sampler of this example, and the soil sample was taken from the soil surface downward.
Of course, in order to more easily observe the soil profile structure, the present invention also provides a further embodiment.
On the basis of the previous embodiments, in particular with reference to fig. 1 to 3, the first unit pipe 110 is composed of two first unit half pipes 1101 assembled. After the soil sample is obtained, the tubular soil sample sampler is horizontally placed on a plane, and the two first unit half pipes 1101, one located below and one located above, are detached from the connecting hoop 130, and the first unit half pipes 1101 located above are removed, so that the soil sample with a layered structure is completely displayed, and the characteristics of the soil sample can be conveniently observed. After the observation is completed, the removed first half-cell 1101 is returned to the laboratory for further analysis in accordance with the sample carrying method of the present invention. Compared with the existing section sample sampling method, the method is more time-saving and labor-saving, and can observe the soil characteristics without affecting the original state of the soil column core soil.
The sample carrying mode is a soil sample in-situ carrying mode, namely the soil sample is carried to a laboratory for analysis and determination in sections under the condition of not damaging the structure of the soil sample.
Specifically, see fig. 2 to 4 and fig. 6 to 7. The embodiment provides a soil sample carrying structure, namely a soil sample preservation box based on a first unit pipe 110, and further two covers are covered at two ends of the first unit pipe 110 to form a soil sample preservation box. After the soil sample is sampled, the connecting hoop 130 is disassembled, the soil sample column is segmented, and the clean and pollution-free cover body 400 is covered on the two ends of the first unit pipe 110, so that the segmented soil sample is stored in a closed space, and the cross contamination of the sample in the sample transferring process is avoided. Meanwhile, the segmented soil sample is completely filled in the soil sample storage box, so that the soil sample structure is not damaged due to jolt of the road surface in the transferring process, the surface soil and the core soil are not mixed, and the core soil is ensured to be pollution-free all the time.
Referring to fig. 2, the present embodiment provides a specific structure of the first unit pipe 110. Both ends of the first unit pipe 110 are provided with a first convex ring 111 and a first annular groove 113.
