The center point of the push shaft 36 is higher than the center point of the support shaft 34, and the sleeve push rod 35 is rotatably connected to the concave block 37.

[0037] The working principle of the model box used for rock and soil model vibration test of the present invention is as follows:

[0038] Step 1: During linkage, the controller 13 is used to start the reduction motor 8, which drives the screw 6 to rotate. The screw 6 rotates inside the slide frame 5. At the same time, the screw 6 carries the sleeve block 7 to move right under the action of the thread transmission force, so that the sleeve block 7 carries the linkage frame 9 to move right, and the linkage frame 9 drives the limit slide 10 to move. The limit slide 10 rotates clockwise around the center point of the turntable 11, and the turntable 11 rotates on the outer wall of the vibration shaft 2. At the same time, the vibration platform 1 supports the vibration shaft 2, and the vibration shaft 2 supports the main box plate 3 to increase the stability of the main box plate 3, and the vibration shaft 2 supports the support ring 4, and the support ring 4 supports the slide frame 5 to increase the stability of the slide frame 5. The turntable 11 can carry multiple rotating frames 17 to rotate clockwise synchronously.

[0039] Step 2. During synchronous docking, multiple rotating frames 17 respectively drive multiple ones to approach the center point of the vibration shaft 2, the limiting column 18 drives the linkage bar 19 to approach the center point of the vibration shaft 2, the linkage bar 19 drives the hinged sleeve 20 to approach the center point of the vibration shaft 2, and the hinged sleeve 20 slides along the outer wall of the guide column 21.

[0040] The hinged sleeve block 20 slides along the inner wall of the sliding frame 22, and the hinged sleeve block 20 drives the connecting shaft 28 to approach the center point of the vibration shaft 2, and the connecting shaft 28 drives the bottom end of the sleeve rod 23 to approach the center point of the vibration shaft 2, and the top end of the sleeve rod 23 drives the hinge rod 29 to move upward. The hinge rod 29 drives the hinge block 24 to move upward, and the hinge block 24 drives the side box plate 25 to rotate counterclockwise upward, and the side box plate 25 drives the hinge shaft 26 to rotate, and the hinge shaft 26 rotates inside the sleeve shaft block 27. Multiple side box plates 25 can all rotate into a vertical state, and multiple side box plates 25 can realize vertical synchronous docking with the four surfaces of the outer wall of the main box plate 3.

[0041] Step 3: When the inside and outside are locked synchronously, the controller 13 starts the transmission motor 32, and the transmission motor 32 drives the linkage screw 31 to rotate on the inner wall of the guide frame 30. The linkage screw 31 carries the two connecting sleeves 33 to approach each other under the action of the thread transmission force. One of the connecting blocks 33 moves to the right, and the other connecting block 33 moves to the left. The connecting block 33 drives the support shaft 34 to move to the right, and the support shaft 34 drives the bottom end of the sleeve push rod 35 to move to the right, and the top end of the sleeve push rod 35 drives the push shaft 36 to move upward, and the push shaft 36 drives the concave block 37 to move upward, and the concave block 37 drives the outer limit frame 44 to move upward, and the outer limit frame 44 slides up along the outer wall of the sliding shaft 42. At the same time, the vibration platform 1 supports the guide frame 30, and the guide frame 30 provides a supporting force for the support block 43, and the support block 43 provides a supporting force for the sliding shaft 42, so that the outer limit frame 44 moves up along the outer walls of the multiple side box plates 25 by pressing and squeezing, so that the outer limit frame 44 can realize rectangular limit locking on the outer walls of the multiple side box plates 25.

[0042] At the same time, the concave block 37 drives the connecting block 38 to move upward, the connecting block 38 drives the connecting strip 39 to move upward, and the connecting strip 39 can drive the connecting rod 40 to move upward, and the connecting rod 40 drives the inner limit frame 41 to move upward, and the inner limit frame 41 moves upward along the inner walls of the multiple side box panels 25. The inner limit frame 41 can realize rectangular limit locking on the inner walls of the multiple side box panels 25, that is, the outer walls and inner walls of the multiple side box panels 25 can be synchronously locked.

[0043] Step 4: During the vibration test of the geotechnical model, a layer of plastic film is laid on the inner wall of the multiple side box plates 25, and a layer of plastic film is laid on the upper surface of the vibration platform 1. The plastic film is used to fill the small gaps at the edge, and then the geotechnical model is placed in the gap surrounded by the multiple side box plates 25. The support legs 12 provide support force to the support frame 16, and the support frame 16 supports multiple vibration springs 15. Then the controller 13 starts the two vibration motors 14, and the vibration motors 14 provide vibration force to the vibration platform 1, and the vibration platform 1 drives the vibration springs 15 to vibrate, and the vibration springs 15 vibrate on the support frame 16.

[0044] The vibration platform 1 drives the vibration shaft 2 to vibrate, and the vibration shaft 2 drives the main box plate 3 to vibrate. The main box plate 3 can vibrate the geotechnical model. After the vibration, the offset value of the geotechnical model is observed, so as to record the offset data.
