[0029] The soil sample wet-dry cycle method is an experimental method used to study the behavior and properties of soil under wet and dry conditions. This method is usually used in soil mechanics, geotechnical engineering, agricultural soil science and other fields. The general steps of the soil sample wet-dry cycle method are as follows: soil sample preparation: representative soil samples are collected from the study area to make soil samples; soil sample wetting: the soil samples are placed in water or fully wetted by watering to simulate the process of soil absorbing water; soil sample drying: the wet soil samples are exposed to a natural dry environment, or the drying process of the soil samples is controlled by drying equipment; cycle repetition: multiple cycles of wetting and drying are performed, and the number of cycles and time intervals can be adjusted according to the needs of the study. After each wetting and drying stage, the soil samples are tested for various mechanical and physical properties, such as shear strength, permeability, porosity, etc. These tests can reveal the changes and responses of soil under wet and dry conditions.

[0032] The inner cavity of the box body 10 is divided into a drying chamber 11 and a drainage chamber 12 from top to bottom by a sample distribution plate 30. A drying pipe 13 is arranged in the drying chamber 11. A water distribution member 40 is arranged above the drying chamber 11. A plurality of water distribution heads 41 are arranged on the water distribution member 40. The water distribution heads 41 are arranged correspondingly just above the soil sample position 31.

[0033] The humidity and temperature monitoring element 20 is used to monitor the temperature in the drying chamber 11 and the humidity of the soil sample at each soil sample position 31 .

[0034] The soil sample wet-dry cycle device provided by the embodiment of the utility model has a soil sample placed on a soil sample position 31, which is a hole opened on the soil sample plate. The water distribution head 41 above the box body 10 distributes water to moisten the soil sample, and excess water of the soil sample enters the drainage chamber 12 from the bottom of the soil sample and is discharged. After the soil sample is moistened, the soil sample is dried by the drying pipe 13, and the gas generated by the drying rises to the drying chamber 11 and is discharged.

[0037] The soil sample dry-wet circulation device provided by the utility model has a small size, occupies a small area, can be carried and used at any time, and realizes the effect of "small size and large function".

[0038] In some feasible embodiments, the humidity and temperature monitoring device 20 includes: a humidity sensing probe 21, a temperature sensing probe 22 and a controller 23.

[0039] The humidity sensing probe 21 is disposed in the soil sample position 31 , the temperature sensing probe 22 is disposed in the drying chamber 11 , and the controller 23 is disposed outside the box 10 and is connected to the humidity sensing probe 21 and the temperature sensing probe 22 , respectively.

According to the temperature of the drying chamber 11, the opening or closing of the drying tube 13 is intelligently controlled; according to the humidity of the soil sample, the opening or closing of the switch water valve 17 is intelligently controlled.

[0041] In some feasible embodiments, an exhaust hole 14 is opened on the side wall of the box body 10 , and the exhaust hole 14 is connected to the drying chamber 11 ; a drain pipe 15 is connected to the side wall of the box body 10 , and the drain pipe 15 is connected to the drainage chamber 12 .

[0042] Excess water from the wetting of the soil sample enters the drainage chamber 12 from the bottom of the soil sample and is discharged through the drainage pipe 15. After the soil sample is wetted, the soil sample is dried by the drying pipe 13. The gas generated by the drying rises to the drying chamber 11 and is discharged through the exhaust hole 14 to maintain the target humidity or temperature in the box 10.

[0043] In some feasible embodiments, the exhaust hole 14 and the drain pipe 15 are located on the same side of the box body 10. In addition, the box body 10 is also provided with a box door.

[0044] In some feasible embodiments, the water distribution member 40 is connected with a water inlet pipe 16, and the water inlet pipe 16 is respectively connected with a plurality of water distribution heads 41, and a switch water valve 17 is installed on the water inlet pipe 16. By setting the water inlet pipe 16 and the switch water valve 17, water is fed into the water distribution member 40, and water is evenly distributed to the soil sample through the water distribution head 41.

[0045] In some feasible embodiments, the water distribution head 41 includes: a water distribution plate 411 and a water dripping head 412, a plurality of water dripping heads 412 are arranged on the water distribution plate 411, and the plurality of water dripping heads 412 are linearly connected through a connecting pipe;

[0046] A rotating head 413 is installed at the center of the water distribution plate 411 , the dripping head 412 close to the rotating head 413 is connected to the rotating head 413 , and the dripping head 412 far from the rotating head 413 is connected to the water inlet pipe 16 .

[0047] In order to achieve uniform water distribution on the soil sample and ensure uniform water penetration, the soil sample is replenished with water through multiple drip heads 412. In order to further evenly distribute water, the drip head 412 is driven by the rotating head 413 to rotate at the center of the water distribution plate 411 to ensure that the soil sample is evenly moistened and the water can evenly penetrate the soil sample. In this embodiment, the rotating head 413 is connected to the motor to realize the rotation of the rotating head 413. The rotation method is to rotate clockwise for one circle and then counterclockwise, and then reciprocate in sequence. In addition, the water distribution head 41 can be driven by a conventional power supply, and can also be driven by a solar panel later. Due to its flexible, compact and highly intensive size, the applicability of the device can be greatly improved, overcoming the shortcomings of the traditional device being bulky and not easy to transport.

[0048] In some feasible embodiments, the water distribution plate 411 is circular in shape, which is more conducive to the installation and use of the drip head 412 and the rotating head 413.

[0049] In some feasible embodiments, the number of the drippers 412 is 3, and the three drippers 412 are evenly arranged on the radius of the water distribution plate 411. Preferably, the uniform arrangement of the three drippers 412 corresponds to the radius range of the soil sample, that is, the connecting line of the three drippers 412 corresponds to the radius of the soil sample, and the three drippers 412 are evenly distributed.

[0050] In some feasible embodiments, the rotating head 413 is located directly above the soil sample position 31. It is more convenient for the water supply head to evenly distribute water to the soil sample through the water distribution head 41 during the rotation process.

[0051] In some feasible ways, support legs 18 are arranged around the bottom of the box 10, and sliding wheels are installed at the lower ends of the support legs 18. The overall stability of the device is improved by the arrangement of the support legs 18. The sliding wheels can be used to achieve movement, which is easy and labor-saving.

[0052] The operation process of the soil sample dry-wet cycle device of the utility model is as follows:

[0053] Open the door of the box 10, place the soil sample at the soil sample position 31, and close the door of the box 10. Open the water valve 17, the rotating head 413 rotates, driving the dripping head 412 to gradually rotate and drip water. The dripping head 412 rotates clockwise and distributes water evenly at intervals. The three dripping heads 412 can make the soil sample evenly moist. After a specific set time of water distribution, the humidity sensing probe 21 located under the soil sample position 31 transmits the humidity data.

[0054] Excess water passes through the hole below the soil sample position 31, enters the drainage chamber 12 and is continuously discharged through the drainage port. At this time, the controller 23 controls the drying tube 13 to open, gradually heats, and realizes the drying of the soil sample. The evaporated water is discharged through the exhaust port. There is a temperature sensing probe 22 in the drying chamber 11. In order to prevent the temperature from being too high, the temperature sensing probe 22 will export temperature data at any time and adjust the temperature threshold. After drying to the set temperature, the controller 23 controls the drying tube 13 to close and start the next cycle.

[0055] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
