Description

Storage box for storing undisturbed soil samples of soil test

Technical Field

The utility model belongs to the technical field of the test equipment technique and specifically relates to a bin for depositing geotechnical test original state soil sample.

Background

The geotechnical test is a test for measuring certain indexes or change rules capable of indicating the basic physical state and mechanical property of soil after soil samples taken from a field needing to be researched are prepared into samples according to the requirements of different test items. The undisturbed soil sample occupies a large proportion in the soil sample of the soil test, but the undisturbed soil sample often causes the soil test data to be inconsistent with the actual situation because the undisturbed soil sample is not stored well. The regulations require that undisturbed soil samples cannot be disturbed by human beings or temperature changes during storage.

At present, most geotechnical laboratories store undisturbed soil samples in a shady and cool place. However, the storage mode is not beneficial to a tester to quickly find the corresponding undisturbed soil sample in actual work, and the undisturbed soil sample is often disturbed to find the undisturbed soil sample and move other soil samples. In addition, the soil sample stored in a shade often causes disturbance of the undisturbed soil sample due to the change of temperature and humidity in the environment, and finally influences the test result.

Therefore, it is very important to reduce disturbance of undisturbed soil to the sample and enhance undisturbed soil sample management.

Detailed Description

The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

as shown in fig. 1-3, the symbols 1-11 in the figures are respectively expressed as: the box body 1, the box door 2, the file box 3, the sealing strip 4, the undisturbed soil sample 5, the middle shaft 6, the sample tray 7, the tray groove 8, the label filling area 9, the thrust ball bearing 10 and the bearing base 11.

Example (b): as shown in fig. 1, the storage box for storing undisturbed soil samples in the soil test in the present embodiment includes a box body 1 and box doors 2, wherein the two box doors 2 are disposed at two sides of the box body 1 and are hinged to each other, so that the box doors 2 can be opened and closed. The box body 1 and the box door 2 jointly form a closed undisturbed soil sample storage space. The inner side surface of the box door 2 is provided with a file box 3 which is convenient for storing relevant paper records. The

box

1 and 2 frames of chamber door correspond the position and are provided with sealing strip 4, and this sealing strip 4 mountable realizes the isolation between the inside storage space of box 1 and the external environment in a week of box 1, guarantees the quality of the original state soil sample of storing in box 1, and then ensures the experimental precision of the geotechnical test who utilizes the original state soil sample to carry out.

As shown in fig. 1, a vertical central shaft 6 is installed inside the box body 1, and three circular sample trays 7 are uniformly spaced in the vertical direction of the central shaft 6. As shown in fig. 3, a center hole is formed in the center of the sample tray 7. A bearing base 11 and a thrust ball bearing 10 are arranged below the sample tray 7, wherein the bearing base 11 is fixedly arranged on the middle shaft 6, the relative position between the two is fixed, the thrust ball bearing 10 is arranged between the sample tray 7 and the bearing base 11, and the middle shaft 6 passes through the middle of the thrust ball bearing 10. In this way, the sample tray 7 is fixed in height position on the central axis 6 and can freely and flexibly rotate around the central axis 6.

As shown in fig. 2, a plurality of tray grooves 8 are uniformly distributed on the sample tray 7, and the plurality of tray grooves 8 are radially arranged along the circumferential direction of the sample tray 7. The diameter of each tray groove 8 is slightly larger than the diameter of the undisturbed soil sample 5, so that each tray groove 8 can contain one undisturbed soil sample 5.

In this embodiment, a corresponding label filling area 9 is respectively disposed near each tray groove 8, and information of the undisturbed soil samples 5 stored in the corresponding tray grooves 8 can be filled in the label filling area 9, so as to realize orderly management of the undisturbed soil samples 5.

The principle of the embodiment is as follows:

a plurality of layers of circular sample trays 7 are arranged in a three-dimensional mode by taking the central shaft 6 as a center, so that the display of undisturbed soil samples 5 is changed from a plane to a three-dimensional mode, and the circular sample trays 7 can rotate around the central shaft 6, so that the samples can be placed and retrieved conveniently.

Firstly, put into inclosed box 1 with original state soil sample 5 and store, have the sealing strip through the frame position at box 1 and chamber door 2, effectively slow down the inside moisture of original state soil sample and environment exchange process, make original state soil sample 5 receive external disturbance littleer.

Secondly, turn to the solid with the mode of putting of original state soil sample 5 from the plane, realize through sample tray 7 that several layers of original state soil samples all can place inside same bin, effectively reduce area.

Thirdly, for tray recess 8 design label filling area 9 on the sample tray 7, the storage record of cooperation undisturbed soil sample 5 realizes the orderly management to undisturbed soil sample 5.

In the embodiment, in specific implementation: in some cases, especially for dealing with the storage requirement of storing a large amount of undisturbed soil samples, the volume of the box body 1 of the storage box is enlarged, a plurality of middle shafts 6 can be arranged in the box body 1, and a plurality of sample trays 7 are arranged on each middle shaft 6, so that the storage amount of the undisturbed soil samples is increased. However, when manufacturing the storage box, attention should be paid to avoiding the position between the sample trays 7 so as not to influence the independent rotation of the sample trays 7 and to meet the storage requirement of the undisturbed soil sample.

As shown in fig. 2, in the present embodiment, each sample tray 7 can hold 18 undisturbed soil samples 5, and the three sample trays 7 can store 54 undisturbed soil samples in total, which has an extremely high space utilization; in the actual use process, the number of the sample trays 7 and the number of the tray grooves 8 formed on the sample trays 7 can be changed according to the storage capacity of the undisturbed soil samples 5.

Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, the description thereof is not repeated herein.
