Description

Technical Field

[0001] The utility model belongs to the technical field of test detection, and in particular relates to an original soil sample conveying device. Background Art

[0002] Original soil samples are also called undisturbed soil samples. They are soil samples that have not changed their physical and chemical components and relatively maintain their natural structure and natural moisture content. They are used to measure the physical and mechanical properties of natural soil, such as gravity, natural moisture content, permeability coefficient, compression coefficient, and shear strength. During the collection and transportation of soil samples, the damage to original soil caused by various human or environmental factors is particularly prominent, especially in recent years, the transportation at the survey site is inconvenient and the traffic conditions are poor, and the samples are often damaged due to bumpy roads. Although some soil samples have obtained relevant data through various tests, their true value depends largely on the degree to which the test soil samples remain in their natural state.

[0003] At present, the original soil samples used for testing pay more attention to the protection of samples during the collection process, but ignore the damage to the soil during the sample transportation process, which increases the error of the test results. Traditional original sample transportation devices mostly use iron boxes, which can easily cause damage to the samples during transportation, and the sample labeling is confusing, and the sample moisture loss is large. Utility Model Content

[0006] The utility model is also characterized in that:

[0007] The sample bottom support comprises a support plate and an airbag platform arranged on the support plate, and the support plate is fastened to the bottom of the shell through a buckle.

[0008] The contact surface between the sample base and the shell is sealed with a rubber cushion.

[0009] The top airbag and the shell wall airbag are communicated with each other through a ventilation hose.

[0010] The top airbag is a foldable airbag.

[0011] The shell is a cylindrical shell.

[0012] A marking slot is arranged on the outer side of the top surface of the shell.

[0013] The beneficial effects of the utility model are:

[0014] The original soil sample transportation device of the utility model is reusable, has a simple structure and is easy to use, can effectively reduce the damage of the sample caused by severe vibration during transportation, and the original sample can be effectively sealed and preserved, thereby ensuring the stability of the shape, structure, and physical and chemical properties of the original sample.

[0017] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0018] Example 1

[0019] The original soil sample conveying device of the utility model has a structure as follows Figure 1 As shown, it includes a semi-enclosed shell 6 with an opening at the bottom, the shell 6 is a cylindrical shell with an inner diameter of 130 mm and a height of 200 mm, an air injection hole 2 is opened on the top of the shell 6, and the bottom opening side of the shell 6 is fastened to the sample base 8 by a buckle 7, a top airbag 4 is arranged on the inner side of the top surface of the shell 6, and a shell wall airbag 5 is arranged on the inner side wall of the shell 6. The shell wall airbag 5 is annular and closely attached to the inner side wall of the shell 6, and the air injection hole 2, the top airbag 4 and the shell wall airbag 5 are connected. The airbag arranged in the shell 6 can effectively reduce the damage of the sample caused by severe vibration during transportation, and a marking card slot 1 is arranged on the outer side of the top surface of the shell 6 to effectively store the marking card for subsequent identification.

[0020] Example 2

[0021] On the basis of Example 1, the air injection hole 2 is connected to the top airbag 4, and the top airbag 4 is connected to the shell wall airbag 5 through the ventilation hose 3. The shell wall airbag 5 is a foldable airbag with a folded shape, and the length of the airbag can be extended by inflation.

[0022] Example 3

[0023] On the basis of Example 2, the sample support 8 includes a bottom plate and an airbag platform arranged on the bottom plate, and the bottom plate is fastened to the bottom opening side of the housing 6 by means of a buckle 7. The contact surface between the sample support 8 and the housing 6 is sealed by a rubber cushion.

[0024] Example 4
