Since the first lifting platform 500 cannot rotate, the first lifting platform 500 is lifted or lowered under the action of the first drive screw 402, that is, the lifting or lowering of the support platform 110 is realized.

[0051] Generally, two first guide rails 130 are provided on the first support frame 300, and at least two first sliders 120 are provided on the first lifting platform 500. Each first guide rail 130 is provided with at least one first slider 120, so that the first lifting platform 500 can accurately move on the first support frame 300, realizing the adjustment of the drilling assembly and the pressing assembly 800 in the first direction.

[0056] After a pilot hole is formed in soft soil by the drilling assembly, the second driving motor 601 moves the support platform 110, that is, moves the drilling assembly away from the pilot hole, and moves the pressing assembly 800 above the pilot hole; during the process of inserting the soil sampler 900 into the pilot hole, the pressing assembly 800 presses the soil sampler 900, making it easier for the soil sampler 900 to be inserted into the pilot hole; after one soil sampler 900 is inserted into the pilot hole, another soil sampler 900 is installed on the soil sampler 900, and the pressing assembly 800 continues to press the soil sampler 900; according to actual requirements, multiple soil samplers 900 are continuously connected during the insertion process.

[0057] Refer to Figure 4 , in an alternative embodiment, the drill pipe assembly 700 includes a drill pipe motor 701 and a drill pipe body 702. The drill pipe motor 701 is arranged on the support platform 110, and one end of the drill pipe body 702 is arranged on the drill pipe motor 701.

[0060] Before the drill pipe body 702 is inserted into the soil sampler 900, the sealing cover 703 is removed from the discharge port, so as not to affect the material in the delivery pipe from spraying out of the discharge port.

[0061] In an alternative embodiment, the pressing assembly 800 includes an oil cylinder, the oil cylinder is arranged at the upper end of the support platform 110, and the movable end of the oil cylinder can extend below the support platform 110.

[0062] The pressing assembly 800 generally selects an oil cylinder, and the movable end of the oil cylinder can move towards the soil sampler 900, thereby pressing the soil sampler 900 into the soft soil; the pressing assembly 800 can also be of other structures.

[0063] In an alternative embodiment, a positioning assembly 160 is arranged on the first support frame 300, and the positioning assembly 160 is located on the side of the first lifting platform 500 away from the first driving assembly 400;

[0066] In an alternative embodiment, a lifting 200 support frame is arranged on the support platform 110, the drill pipe assembly 700 is arranged on the lifting 200 support frame, and the lifting 200 support frame is used to lift 200 the drill pipe assembly 700 along the first direction.

[0067] To avoid the drill pipe assembly 700 affecting the operation of the pressure application assembly 800 or during the process of the pressure application assembly 800, a lifting 200 support frame is provided on the support platform 110, and the drill pipe assembly 700 is arranged on the lifting 200 support frame. When the drill pipe assembly 700 is not needed, the drill pipe assembly 700 moves away from the support platform 110 to avoid the pressure application assembly 800 being affected by the drill pipe assembly 700 and the pressure application assembly 800 being too long.

[0068] In an alternative embodiment, it further includes a crawler vehicle 100, and one end of the first support frame 300 away from the first drive assembly 400 is hinged to the crawler vehicle 100;

[0069] A lifting 200 assembly is provided on the crawler vehicle 100, one end of the lifting 200 assembly is connected to the crawler vehicle 100, and the other end is connected to the first support frame 300; the lifting 200 assembly is used to make the first support frame 300.

[0070] A lifting 200 assembly is provided on the crawler vehicle 100. Generally, the lifting 200 assembly is a hydraulic cylinder. One end of the hydraulic cylinder is hinged to the crawler vehicle 100, and the other end is hinged to the first support frame 300. When the first support frame 300 needs to be vertical, the hydraulic cylinder extends to make the first support frame 300 vertical, and then operations such as drilling the soft soil are carried out.

[0071] After use, the lifting 200 assembly makes the first support frame 300 tilt or lie flat on the crawler vehicle 100, which reduces the height of the crawler vehicle 100 and facilitates the transportation of the crawler vehicle 100.

[0072] Since the surface bearing capacity of the soft soil is very low, if the crawler vehicle 100 tilts during operation and drives the soil sampler 900 to deflect, it is reset by adjusting the telescopic screw 162; generally, the fixed sleeve is connected to the positioning sleeve 161 through three telescopic screws 162.

[0073] The in-situ solidification test device for soft soil does not need to move the crawler vehicle 100 during the three processes of pilot hole drilling, pressing the soil sampler 900, and stirring and solidifying. Only the support platform 110 needs to be moved, which not only simplifies the construction process but also prevents the crawler vehicle 100 from deflecting in the soft soil during frequent movement.

[0074] The in-situ solidification test device for soft soil is provided with a positioning sleeve 161. This positioning sleeve 161 can not only fix the soil sampler 900 when the soil sampler 900 is pressed into the soil but also correct it when the soil sampler 900 is displaced, ensuring the smooth progress of subsequent solidification tests.

[0075] If the soil sampler 900 is tilted, displaced, etc., it is very difficult for the drill pipe body 702 of the subsequent solidification test to smoothly stir and spray slurry to reinforce the soft soil in the soil sampler 900.

[0076] On the first support frame 300 of the in-situ soft soil solidification test device provided by the utility model, a first lifting platform 500 is slidably arranged, and a support platform 110 is arranged on the first lifting platform 500.

After the test is completed, the pressing assembly 800 takes out the soil sampler 900, and then cures the soil strengthened in the soil sampler 900, and then conducts various indoor tests to obtain some properties of the strengthened soil, especially the strength property.

[0077] Since the solidification test is carried out in-situ, the solidified soil body will not be disturbed during the process of soil sampling and transportation, which greatly improves the authenticity of the test data and provides more reliable test data for subsequent engineering construction.

[0078] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
