[0015] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1-3As shown, the soil column shear force tensile testing machine provided by the utility model includes a tensile machine base 1, on which a control button 15 and a power switch 16 are provided for starting and controlling the operating state of the tensile machine, on which a tensile machine column 2 is provided, and two groups of tensile machine columns 2 are arranged relatively to each other, and a top crossbeam 3 is installed on the tensile machine column 2, and a sensor crossbeam 4 is connected between the two groups of tensile machine columns 2, and the sensor crossbeam 4 is slidably connected to the two groups of tensile machine columns 2, and a screw transmission mechanism is arranged in the tensile machine column 2 and connected to the sensor crossbeam 4 to control the lifting movement of the sensor crossbeam 4, and a force sensor 5 is installed at the bottom of the sensor crossbeam 4, and a soil column shearing tool 6 is provided on the tensile machine base 1; the soil column shearing tool 6 includes an adjustment base 7 and a soil column clamp seat 8, and the adjustment base 7 is convenient for adjustment and quick switching of different toolings, and the soil column clamp seat 8 is used to fix the soil column sample.

[0018] like Figure 2 and 3 As shown, the soil column clamp 8 is divided into two groups, the left and right groups. The soil column clamp 8 on the right side is connected to the force sensor 5, and the soil column clamp 8 on the left side is installed on the adjustment base 7. The soil column clamp 8 on the right side and the soil column clamp 8 on the left side are arranged in an inverted state. During the tensile testing, the force sensor 5 moves upward with the soil column clamp 8 on the right side, while the clamp on the left side is fixed on the base, thereby generating a shear force to shear the soil column.

[0019] like Figure 2 and 3 As shown, the soil column clamp seat 8 is connected by an upper clamp block 9 and a lower clamp block 10 through a hinge. The side ends of the upper clamp block 9 and the lower clamp block 10 away from the hinge connection are provided with a slot 11. A live bolt 12 is hinged in the slot 11 of the lower clamp block 10. The thread on the live bolt 12 is adapted to be equipped with a butterfly nut 13. The live bolt 12 cooperates with the butterfly nut 13 to quickly achieve a latch effect and hold the soil column sample tightly.

[0020] like Figure 2 and 3 As shown, arc-shaped grooves are arranged on the walls facing the upper clamp block 9 and the lower clamp block 10, and the inner sides of the arc-shaped grooves of the upper clamp block 9 and the lower clamp block 10 are filled with rubber spacers 14, which more realistically feedback the shear fracture state of the soil column rather than the metal shear fracture.

[0021] When in use, first unscrew the butterfly nut 13 on the live knot bolt 12, rotate the upper clamp block 9 and the lower clamp block 10 through the hinge connection to connect, place the soil column sample between the upper clamp block 9 and the lower clamp block 10, then rotate and close the upper clamp block 9 and the lower clamp block 10, the live knot bolt 12 is stuck in the slot 11, tighten the butterfly nut 13, quickly achieve the latch effect, hold the soil column tightly, power on the entire device, and then turn on the power switch 16, control the operating state of the sensor beam 4 through the control button 15, and the screw transmission mechanism in the tensile machine column 2 controls the movement of the sensor beam 4. During the tensile machine test, the force sensor 5 moves upward with the right soil column clamp seat 8, while the left clamp seat is fixed on the base, thereby generating a shear force to shear the soil column. The force sensor 5 is used to detect the stress condition of the soil column when it is sheared.

[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
