[0054] Embodiment 2

[0055] On the basis of the embodiment 1, the model test box for simulating landslide damage provided by the embodiment is used as follows: in order to facilitate the application of horizontal and vertical loads to the landslide model, a linear power mechanism including a first support frame 3 and a second support frame 2 is arranged outside the box body 1. The first support frame 3 is arranged outside the box body 1 and fixedly connected with the box body 1. The second support frame 2 is arranged as a door-shaped frame and fixedly arranged. A cross rod 5 is arranged inside the door-shaped frame, and a height adjusting assembly is arranged between the cross rod 5 and the door-shaped frame. The linear power mechanism includes an extension member 10.

The other end of the extension member 10 is connected with a push plate 107. The extension member 10 can be selected from a jack, an electric telescopic rod or a pneumatic cylinder.

[0056] Since the first support frame 3 is fixed with the box body 1, the linear member 406 can be connected with the box body 1 and tightly abut against the stand 404, so that the box body 1 is prevented from sliding in the horizontal direction when the first support frame 3 is pulled, and the side of the box body 1 is facilitated to be lifted with the first support frame 3. A lifting lug is arranged at the top of the first support frame 3, facilitating the connection of a steel cable.

[0057] When the vertical load needs to be applied, the extension member 10 is fixed on the cross rod 5, the moving end of the extension member 10 faces downward, the moving end of the extension member 10 applies the vertical load to the push plate 107, and the plane of the push plate 107 is horizontal and faces downward.

[0062] like Figure 7 As shown, the sleeve is fixed to the steel plate, not fully closed. A nut is welded to one end of the sleeve. A screw is fixed to the other end, passing through the nut. Together, these parts form a hoop structure. The diameter of the sleeve is slightly larger than the diameter of the base of the telescopic member 10. During use, the upper screw is tightened to close it and secure the telescopic member 10.

[0063] In this embodiment, the telescopic member 10 can be a commonly used manual hydraulic jack (25t) on the market. It can be replaced according to actual test requirements, but it must be ensured that the base diameter does not exceed the diameter of the hoop.

[0065] In this embodiment, the side panel of the box body 1 close to the support frame is detachably connected to the box body 1 and can be disassembled using nuts and L-shaped anchors. When the push plate 107 is arranged inside the box body 1, it is located on the side close to the support frame.

[0066] The use method and working principle of the embodiment

[0067] When the horizontal load needs to be applied to the slope material, the base of the jack is fixed on the second ring 9, the telescopic part of the jack is supported by the support 11, so that the jack can be extended in the horizontal direction.

The handle of the jack is rotated, the telescopic end of the jack extends to the push plate 107 and abuts against the push plate 107, and the jack is continuously extended to push the push plate 107 to move in the horizontal direction. When the vertical load needs to be applied to the slope material, the limiting part 8 is loosened, and then the cross bar 5 is slid up and down to a suitable height. Then the base of the jack is fixed on the first ring 6, the handle of the jack is rotated, the telescopic end of the jack moves downward, and the telescopic end of the jack abuts against the push plate 107 to apply a vertical load to the slope material through the push plate 107.
