Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of frozen soil sampling, in particular to an improved frozen soil thawing sampling device. Background Art
[0002] Frozen soil refers to various rocks and soils below zero degrees Celsius and containing ice. It can generally be divided into short-term frozen soil, seasonal frozen soil and perennial frozen soil. Frozen soil has rheological properties and its long-term strength is far lower than its instantaneous strength characteristics. Due to these characteristics, the construction of engineering structures in frozen soil areas must face the two major dangers of frost heave and thaw settlement. As the climate warms, the frozen soil is constantly degrading.
[0003] The utility model patent with authorization announcement number CN219736881 U discloses "A Frozen Soil Thawing Sampling Device", which rotates the adjustment block along the circular groove opened by the support rod to the middle position of the base of the sampling device, and then presses the pressure rod downward to drive the plug block to squeeze the reset spring and the lifting rod downward. When the top of the plug block is completely out of the slot, the first fixed rod is pushed to one side, driving the roller to move inside the guide groove, and at the same time driving the second fixed rod and the heating plate to move to one side at the same time. When the position that needs to be adjusted is reached, the pressure rod stops being pressed, and the reset spring automatically rebounds to drive the plug block to be inserted into the slot and fixed, which is used to adjust the position of the thawing device.
[0004] However, the above-mentioned prior art solutions still have the following deficiencies: in the above-mentioned device, the frozen soil at the sampling location is thawed by a heating plate, however, the heating plate can only heat and thaw the relatively superficial frozen soil, and the thawing effect on the frozen soil at a slightly deeper location is general; secondly, the bottom of the base of the sampling device lacks a structure for movement, and the entire device needs to be transported to the area to be sampled, which requires a lot of manual labor.

[0029] Specifically, the gantry 21 is fixedly connected to the top of the base 1 , and the first cylinder 31 is fixedly connected to the top of the gantry 21 and is located on the left side of the second cylinder 22 .
[0030] Through the above technical solution, the gantry 21 provides a mounting carrier for the first cylinder 31 and the second cylinder 22 .
[0031] Specifically, the first slide plate 32 and the second slide plate 23 are both located inside the gantry 21 , and the front and rear sides of the first slide plate 32 and the second slide plate 23 are both slidably connected to the inner wall of the gantry 21 .
[0032] Through the above technical solution, since the first slide plate 32 and the second slide plate 23 are both slidably connected to the inner wall of the gantry 21, the first slide plate 32 and the second slide plate 23 can be prevented from being positionally offset during the lifting process.
