[0002] Soft soil generally refers to a kind of cohesive soil with high natural water content, high compressibility, low bearing capacity and very low shear strength in a soft plastic to flow plastic state. Soft soil is a general term for a kind of soil, not a specific soil. In engineering, soft soil is often subdivided into soft cohesive soil, silt soil, silt, peat soil and peat. It has the characteristics of high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex stratified distribution of soil layers, and large difference in physical and mechanical properties between layers.

[0022] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0023] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figures 1-6 As shown, a soft soil geological exploration device includes two transparent semi-cylinders 2, which can be detachably combined to form a complete cylinder. It also includes: openings 11, with multiple openings 11 on the semi-cylinders 2; a left fan 5, with multiple left fans 5 fixed to the left semi-cylinder 2; a right fan 7, with multiple right fans 7 fixed to the right semi-cylinder 2; and air ducts 14, with air ducts 14 installed on the air outlets 15 of both the left and right fans 5. An electric heating wire 13 is fixed inside the air duct 14 on the side where the left fan 5 is located. The device also includes cooling and heating elements. The heating mechanism includes a cooling and heating mechanism located below the right fan 7; a protective box 6 is fixed to the outer wall of the half-cylinder 2, with the left fan 5 and the right fan 7 both located inside the protective box 6; a ventilation pipe 4 is provided on one side of the half-cylinder 2, with the bottom of the ventilation pipe 4 closed, and the ventilation pipe 4 is fixedly connected to and communicates with the protective box 6 through multiple connecting pipes 3; and a breathable membrane 12 is provided on the inner wall of the half-cylinder 2 to cover the opening 11, with connecting blocks 10 fixedly provided at the top and bottom of the breathable membrane 12, and the connecting blocks 10 are fixedly connected to the inner wall of the half-cylinder 2.

[0026] The cooling and heating mechanism includes: a cooling pipe 23, which is fixedly connected to the half-cylinder 2; a water injection pipe 19, one end of which is fixedly connected to and connected to the cooling pipe 23, and the other end of which passes through the protective box 6 and extends to the outside of the protective box 6; a sealing cap 20, one end of which extends to the outside of the protective box 6 and is threadedly connected to the sealing cap 20; a water tank 21, which is located below the cooling pipe 23 and is fixedly connected to the inner wall of the protective box 6; and a heater 22, which is fixedly installed at the bottom of the water tank 21.

[0027] The left fan 5 is wirelessly connected to the first controller 24, the heating wire 13 is wirelessly connected to the second controller 25, the right fan 7 is wirelessly connected to the third controller 26, and the heater 22 is wirelessly connected to the fourth controller 27; the first controller 24, the second controller 25, the third controller 26, and the fourth controller 27 are all installed on the control board 28.

[0028] Working principle: Ice water is injected into the cooling pipe 23 through the water injection pipe 19. Then, the sealing cap 20 is threadedly connected to the water injection pipe 19. The cylinder composed of two half-cylinders 2 is inserted into the soil. Then, the left fan 5 is controlled by the first controller 24 to blow air, and the heating wire 13 is controlled by the second controller 25 to start heating, so that the left fan 5 blows hot air into the cylinder to dry the soil. At the same time, the right fan 7 is started by the third controller 26 to draw in the water vapor generated by drying the soil and discharge it towards the cooling pipe 23. The water vapor liquefies upon encountering the cold and flows into the water tank 21. The cylinder is pulled out of the soil, and the ice water in the cooling pipe 23 is released. Then, the heater 22 is started by the fourth controller 27 to heat and evaporate the water in the water tank 21 to generate water vapor. Then, the right fan 7 is controlled by the third controller 26 to switch to blowing mode, and the water vapor generated by the heater 22 is blown into the cylinder to moisten the soil and restore the soil.

[0029] Example 2

[0030] like Figures 1-5 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that it also includes a partition mechanism, which is installed between the two semi-cylinders 2. The partition mechanism includes: a rotating shaft 1; sleeves 9, with multiple sleeves 9 sleeved on the rotating shaft 1, the rotating shaft 1 and the sleeves 9 being rotatably connected, and the sleeves 9 being fixedly connected to the left semi-cylinder 2 through a support rod 17; a folding flexible plate 18, with the lower end of the folding flexible plate 18 fixedly connected to the support rod 17, the upper end of the folding flexible plate 18 fixedly connected to the rotating plate 16, and the rotating plate 16 fixedly connected to the rotating shaft 1.

[0031] Working principle: Rotating the rotating shaft 1 causes the rotating plate 16 to rotate one revolution. The rotating plate 16 drives the folding soft plate 18 to unfold and divide the internal space of the cylinder, thereby preventing the soil inside the cylinder from separating from the cylinder when it is pulled out.
