[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0019] See also Figure 1 and Figure 2 , a soft soil shear displacement detection device, comprising an electric control cabinet 1, a distribution box 2 is electrically connected to the bottom of the electric control cabinet 1, a terminal 3 is electrically connected to the shell of the distribution box 2, an operation panel 4 is electrically connected to the shell of the electric control cabinet 1, a fixed base 5 is fixedly arranged on the side of the distribution box 2, a pressure sensor 6 electrically connected to the operation panel 4 is arranged above the fixed base 5, a ring-mounted lower box 7 is fixedly arranged above the pressure sensor 6, an upper box 8 is arranged above the lower box 7, a telescopic rod 9 is installed on the side of the upper box 8, the telescopic rod 9 is transmission-connected to the motor drive box 10 arranged on the side of the electric control cabinet 1, a tension sensor 11 electrically connected to the operation panel 4 is installed in the middle of the telescopic rod 9, a slide rail 12 is arranged on the side of the electric control cabinet 1, an electric slide seat 13 electrically connected to the electric control cabinet 1 is slidably installed on the slide rail 12, a connecting frame 14 is arranged on the side of the electric slide seat 13, and a soft soil pressing block 15 is arranged below the connecting frame 14;

[0020] The operation panel 4 includes a circuit board 401, a display screen 402 is electrically connected to the surface of the circuit board 401, a numeric keypad 403 and function buttons 404 electrically connected to the circuit board 401 are arranged below the display screen 402, and a switch button 405 electrically connected to the circuit board 401 is arranged below the function button 404.

[0021] See also Figure 1 The distance between the lower box 7 and the upper box 8 is 0.5-1 cm. This arrangement can avoid the influence of the friction between the lower box 7 and the upper box 8 on the soft soil shear displacement test data, thereby improving the detection accuracy.

[0022] See also Figure 3 A plurality of drainage holes 16 are formed on the upper box 8 and the lower box 7. Such an arrangement allows the water in the soft soil to be discharged through the drainage holes 16 when required by certain test items, so as to conduct a shear displacement test on the drained soft soil.

[0023] See also Figure 1The inner diameter of the upper box 8 is 2 cm larger than the diameter of the soft soil pressing block 15. This arrangement can ensure that when the telescopic rod 9 drives the upper box 8 to contract to detect the soft soil shear data, the inner wall of the upper box 8 will touch the soft soil pressing block 15 only after the soft soil shear displacement is at least 2 cm, leaving a displacement margin for the soft soil, thereby avoiding affecting the soft soil shear displacement test data.

[0024] See also Figure 1 and Figure 3 The lower box 7 and the upper box 8 are both made of titanium alloy material. The titanium alloy material has strong corrosion resistance, high structural strength, and is not easy to deform. It can remain unchanged under high pressure, thereby ensuring the service life of the device and avoiding frequent replacement of the lower box 7 and the upper box 8.

[0025] Working principle: When using this device, the external power grid is connected through the terminal 3. The power input from the terminal 3 is rectified by the distribution box 2 and then input into the electric control cabinet 1 to power the device. The working instruction is input through the operation panel 4. The operation panel 4 controls the motor drive box 10 to move and reset, so that the upper box 8 and the lower box 7 are consistent in the vertical direction, and the soft soil to be tested is filled into the lower box 7 and the upper box 8. After filling, the working instruction is input through the operation panel 4, and the operation panel 4 controls the electric slide 13 to move downward along the slide rail 12, so that the soft soil pressing block 15 contacts the inside of the upper box 8, exerting a certain force on the soft soil. At the same time, the pressure sensor The device 6 detects the magnitude of the force in real time and feeds it back to the operation panel 4 for processing. When the force applied by the soft soil pressing block 15 reaches the set value, the operation panel 4 controls the electric slide 13 to stop moving downward, and controls the motor drive box 10 to drive the upper box 8 to contract through the telescopic rod 9, so that the soft soil in the upper box 8 and the lower box 7 completes the shear displacement. The force applied to the soft soil during the shearing process is detected by the tension sensor 11 in real time and fed back to the operation panel 4 for recording, so that the staff can check it at any time. The device can be automatically operated, simple to operate, and easy to use. At the same time, relevant data can be detected and fed back in real time during operation, and the data accuracy is high.
