specific Embodiment approach 1
[0039] Specific implementation mode one: combine figure 1 , figure 2 and image 3 Describe this embodiment. This embodiment includes a chassis 1 and a telescopic measuring tube. The telescopic measuring tube includes a plurality of sleeve-type monomers 2. The multiple sleeve-type monomers 2 are sequentially arranged on the chassis 1 from bottom to top. The monomer 2 includes a pipe body 2-1, an anchor plate 2-2 and a displacement sensor 2-3, the anchor plate 2-2 is set outside the pipe body 2-1, and the displacement sensor 2-3 is set on the pipe body 2-1 On the inner wall, the top end of the pipe body 2-1 is processed with a boss 2-4, and the bottom end of the pipe body 2-1 is processed with a groove 2-5, and the pipe body 2-1 of a casing type monomer 2 passes through the boss respectively. 2-4 and the groove 2-5 are slidingly matched with the two adjacent sleeve type monomers 2 .
[0040] Further, the tube body 2-1 of a sleeve-type monomer 2 slides with the groove 2-5 in ...
specific Embodiment approach 2
[0049] Embodiment 2: This embodiment is a further limitation of Embodiment 1. The displacement sensors 2-3 are linear displacement sensors, and there are many types to choose from, such as rod-type linear displacement sensors or slider-type linear displacement sensors. The displacement sensor 2-3 is an existing product, and its use process is the same as that of the existing product.
specific Embodiment approach 3
[0050] Specific implementation mode three: combination figure 1 , figure 2 , image 3 and Figure 4 Describe this implementation mode, this implementation mode includes the following content:
[0051] Determine the depth of the permafrost layer in the test area according to the geological survey report, determine the number of sleeve-type monomers 2 in the frost heave device according to the depth of the permafrost layer, install the frost heave device in the test area, and obtain different periods of time through the frost heave device Frost heave data of the frost heave layer, according to the frost heave data fed back by the frost heave device, the frost heave deformation of the frozen soil in the test area is obtained.
