[0030] In addition, it should be noted that the connections involved in the present invention can be achieved by using conventional connection methods and do not involve any innovation.

[0031] The subject of the present invention is a model test box for simulating landslide damage. Slope sliding usually occurs in bank slope areas, mountainous excavation slope areas, rainstorm-prone areas or abnormally heavy rainfall areas. In the field of geotechnical engineering and geological engineering, the soil or rock on the slope, affected by factors such as river scouring, groundwater activity, rainwater soaking, earthquakes and artificial slope cutting, slides down the slope as a whole or dispersedly along a certain weak surface or weak zone under the action of gravity, forming a landslide.

[0032] Landslides can easily cause damage to agriculture, industry, transportation, water conservancy projects, economic losses, casualties, etc. Therefore, a device that can simulate landslide damage is needed to evaluate the conditions that cause landslide damage and estimate its impact.

[0033] At present, there are some devices for simulating landslide damage tests. Some of them can only apply horizontal loads to the landslide model, and some can only apply vertical loads to the landslide model. It is difficult to use one model box to simulate multiple landslide test conditions, which is not conducive to saving test research costs and also limits the development of landslide damage model tests under complex conditions.

[0034] Based on the above reasons, the present invention provides a model test box for simulating landslide damage, so as to solve the above-mentioned technical problems. Figures 1 to 11 , the present invention is described in detail.

[0035] Example 1 This embodiment provides a model test box for simulating landslide damage, such as Figures 1 to 6 As shown, the model test box includes a box body 1, at least one side of which is set as a transparent first side plate 101, and also includes a push plate 107, a linear power mechanism, and an angle adjustment mechanism 4.

[0036] The box 1 can be filled with concrete, gravel, sand, etc. to construct a landslide model. The first side plate 101 is a transparent organic glass plate, which is commercially available and is assembled to the front of the box 1 by screws.

[0037] like Figure 2 As shown, the back side plate of the box body 1 is connected to the box body 1 by a hinge element, and the back side plate is connected by a nut and an L-shaped screw. The back side plate of the box body 1 is opened by raising and lowering the L-shaped screw.

[0038] The push plate 107 is vertically arranged on one side of the box body 1 or horizontally arranged on the top of the box body 1. The linear power mechanism is arranged outside the box body 1, and the linear power mechanism has a power output end, which is connected to the push plate 107. When the push plate 107 is arranged on one side of the box body 1, the power output end is used to push the push plate 107 to move in the horizontal direction, and when the push plate 107 is arranged on the top of the box body 1, the power output end is used to push the push plate 107 to move in the vertical direction. The angle adjustment mechanism 4 is arranged outside the box body 1, and the angle adjustment mechanism 4 has a tension output end, which is connected to one side of the box body 1 and is used to pull one side of the box body 1 upward, thereby changing the inclination angle of the box body 1.

[0039] The push plate 107 can be used to apply horizontal or vertical loads to the landslide model, and the angle adjustment mechanism 4 can be used to change the inclination of the box 1, thereby realizing landslide damage simulation under complex working conditions. The specific conditions of the landslide damage and the sliding surface can be observed through the transparent first side panel 101.

[0040] In this embodiment, the angle adjustment mechanism 4 includes a column 404, a winding wheel 403, a pulley 405, a linear element 406, and a rotating power assembly. The column 404 is fixedly arranged on the side of the box 1 away from the first support frame 3. The bottom of the column 404 is rotatably provided with a winding wheel 403, and the top of the column 404 is rotatably provided with a pulley 405. The output end of the rotating power assembly is connected to the winding wheel 403 to drive the winding wheel 403 to rotate. The linear element 406 is made of a flexible material, one end of the linear element 406 is fixed on the winding wheel 403, and the other end is passed around the pulley 405 and fixedly connected to the box 1. The linear element 406 can be selected as a steel cable.

[0041] In this embodiment, the column 404, the winding wheel 403, the pulley 405, and the linear element 406 are all arranged in two groups in parallel, and the rotating power assembly includes a transmission box 402, a motor 401, a first rotating shaft 407, a first gear 408, a second rotating shaft 409, and a second gear 410. The output end of the motor 401 is fixedly connected to the first rotating shaft 407, the first rotating shaft 407 is fitted with a first gear 408, the second rotating shaft 409 is fitted with a second gear 410, the second gear 410 is meshed with the first gear 408, and the two ends of the second rotating shaft 409 are respectively connected to the two groups of winding wheels 403.

[0042] The first rotating shaft 407, the first gear 408, the second rotating shaft 409, and the second gear 410 are all arranged inside the transmission box 402, and the transmission box 402 is arranged between the two pillars 404. The transmission box 402 can prevent the falling objects from damaging the rotating power assembly when the required slope material is filled into the box body 1, and can play a certain protective role.

[0043] The motor 401 is connected to a controller 12 , and the controller 12 is connected to a power source 13 .

[0044] The first rotating shaft 407 and the second rotating shaft 409 can be arranged perpendicularly or parallel to each other. When the two are arranged perpendicularly, the first gear 408 and the second gear 410 are both arranged as bevel gears. When the two are arranged parallel to each other, the first gear 408 and the second gear 410 are both arranged as spur gears.

[0045] The usage and working principle of this embodiment The model test box for simulating landslide damage provided in this embodiment is used to start the motor 401, and the motor 401 drives the first rotating shaft 407 to rotate, and the first gear 408 on the first rotating shaft 407 rotates accordingly, and the first gear 408 drives the second gear 410 meshing therewith to rotate, and the second rotating shaft 409 rotates accordingly, and the second rotating shaft 409 drives the winding wheel 403 to rotate, and when the winding wheel 403 rotates, the linear element 406 is wound on the winding wheel 403. Since the linear element 406 is connected to the box body 1 by bypassing the pulley 405, when the linear element 406 is retracted, it pulls one side of the box body 1 upward, thereby changing the angle of the box body 1.

[0046] Example 2 On the basis of Example 1, the model test box for simulating landslide damage provided in this embodiment, in order to facilitate the application of horizontal and vertical loads to the landslide model, a linear power mechanism is arranged on the outside of the box body 1, including a first support frame 3 and a second support frame 2, the first support frame 3 is arranged outside the box body 1, the first support frame 3 is fixedly connected to the box body 1, the second support frame 2 is arranged as a portal frame, the second support frame 2 is fixedly arranged, a cross bar 5 is arranged inside the portal frame, a height adjustment component is arranged between the cross bar 5 and the portal frame, and the linear power mechanism includes a telescopic member 10, one end of the telescopic member 10 is used to be detachably connected to the cross bar 5 or to be detachably connected to the first support frame 3, and the other end of the telescopic member 10 is connected to the push plate 107. The telescopic member 10 can select a jack or an electric telescopic rod or a cylinder.

[0047] Since the first support frame 3 is fixed to the box body 1, the linear member 406 can be connected to the box body 1 to press the box body 1 against the column 404, so as to prevent the box body 1 from sliding in the horizontal direction when the first support frame 3 is pulled, so that one side of the box body 1 is lifted with the first support frame 3. A lifting lug is provided on the top of the first support frame 3 to facilitate the connection of the steel cable.

[0048] When a vertical load needs to be applied, the telescopic member 10 is fixed on the crossbar 5, with the moving end of the telescopic member 10 facing downward, and the moving end of the telescopic member 10 applies a vertical load to the push plate 107, and the plane of the push plate 107 is horizontal and facing downward.

[0049] When a horizontal load needs to be applied, the base end of the telescopic member 10 is fixed on the first support frame 3, the moving end of the telescopic member 10 is facing the direction of the box body 1, and the moving end of the telescopic member 10 is connected to the push plate 107, and the plane of the push plate 107 is vertical and faces the inside of the box body 1.

[0050] In this embodiment, the height adjustment assembly includes a slide groove 7 and a limit member 8. Two oppositely arranged slide grooves 7 are respectively arranged on the two sides of the door frame. The two ends of the cross bar 5 are respectively arranged in the corresponding slide grooves 7. The cross bar 5 is slidably connected to the slide groove 7. The limit member 8 is threadedly connected to the cross bar 5, and the limit member 8 is used to lock the position of the cross bar 5.

[0051] During the test, the height of the crossbar 5 can be adjusted according to the height of the slope material inside the box 1 through the height adjustment component.

[0052] In this embodiment, a first hoop 6 is welded and fixed to the bottom of the crossbar 5 , and the first hoop 6 is used to fix the base of the telescopic member 10 . Specifically, when in use, the first hoop 6 fastens the base of the telescopic member 10 to fix the telescopic member 10 .

[0053] like Figure 7 As shown, the sleeve is fixed on the steel plate, the sleeve is not completely closed, and a nut is welded on one end of the sleeve. A screw is fixed on the other end, and the screw passes through the nut. These parts together form a hoop structure. The diameter of the sleeve is slightly larger than the diameter of the base of the telescopic member 10. When in use, the upper screw is tightened to close it and fix the telescopic member 10.

[0054] In this embodiment, the telescopic member 10 can be a commonly used manual hydraulic jack (25t) on the market, which 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.

[0055] In this embodiment, a steel plate is fixed on the first support frame 3, and a second hoop 9 is arranged on the steel plate. The second hoop 9 is used to fix the base end of the jack. A bracket 11 is arranged between the first support frame 3 and the box body 1. Figure 4 As shown, it is a three-dimensional schematic diagram of the use of the jack and the bracket 11. When the jack is pressurized, the bracket 11 can be placed between the first support frame 3 and the box body 1 so that the protruding part of the jack is supported and keeps moving forward in a straight line. The bracket 11 is used to support the jack when the horizontal thrust is initially applied. The jack is unscrewed, and the bracket 11 can be removed after the jack head hits the smooth steel plate (after being stressed).

[0056] 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.

[0057] The usage and working principle of this embodiment When the model test box provided in this embodiment is in use, when it is necessary to apply a horizontal load to the slope material, the base of the jack is fixed on the second hoop 9, and the telescopic part of the jack is supported by the bracket 11, so that the jack can be telescoped in the horizontal direction. At this time, the push plate 107 is arranged on the side of the box body 1 close to the jack, and the handle of the jack is rotated, and the telescopic end of the jack extends to the push plate 107 until it is tightly against the push plate 107, and the jack is continued to extend to push the push plate 107 to move in the horizontal direction; when it is necessary to apply a vertical load to the slope material, first loosen the limit piece 8 and then slide the cross bar 5 up and down to a suitable height, and then fix the base of the jack on the first hoop 6, rotate the handle of the jack, and the telescopic end of the jack moves downward, and the telescopic end of the jack is tightly against the push plate 107, and the push plate 107 applies a vertical load to the slope material.

[0058] Example 3 On the basis of Example 1 and Example 2, in order to facilitate the adjustment of the size of the landslide model and adjust the proportion of the constructed landslide model in different directions, so as to further simulate the real landslide damage, in this embodiment, the box body 1 has two opposite third side panels 102 on both sides, and the inner side surfaces of the third side panels 102 are provided with a plurality of limit grooves 103, which are opened in the vertical direction and also include a first adjustment plate 105, which is used to be clamped in the two opposite limit grooves 103.

[0059] According to different width requirements for the landslide model, the first adjustment plate 105 is arranged in the corresponding limiting groove 103 .

[0060] In order to facilitate the adjustment of the height of the slope material, a plurality of limiting holes 104 are provided on the third side plate 102. The limiting holes 104 are spaced apart from the limiting grooves 103. In order to prevent the slope material from flowing out of the limiting holes 104, each limiting hole 104 is threadedly connected to a limiting rod. A second adjusting plate 106 is provided in the box body 1. Threaded holes are provided on both sides of the second adjusting plate 106. The threaded holes are used to match the threaded connection with the limiting rod.

[0061] Under normal conditions, each limiting hole 104 is threadedly connected to a limiting rod. When the position of the third side panel 102 needs to be adjusted, after the third side panel 102 is moved to a corresponding height position, the limiting rod is further screwed inward until it is screwed into the corresponding threaded hole of the third side panel 102, and the third side panel 102 is tightened to fix it.

[0062] How to use this embodiment like Figure 6 The figure shows a three-dimensional schematic diagram of the side panel of the box body 1. Figure 6-1The steel plate has semicircular columns at both ends. The box body 1 has limit grooves matching the semicircular columns on both sides. The length is equal to the radius of the semicircular columns at both ends, the height is equal to the length and height of the box body 1, and the width is equal to the diameter of the semicircular columns at both ends. The box body 1 can be vertically inserted into the box body 1. Figure 6-2 There are threaded holes in the center of both ends of the steel plate, and there are limit holes between the grooves at both ends of the box body 1. The limit rods are threadedly connected in the limit holes, and the threaded holes can match the threaded connection with the limit rods. Figure 6-2 The length of the steel plate is the length of the inside of the box 1. The height needs to take into account the load of the simulated landslide material. For recycling, it can be made higher. The width can be changed according to the limit holes between the grooves at both ends of the box 1. For ease of use, five kinds of steel plates with different widths can be directly made to match the limit holes between the grooves at both ends of the box 1. By using Figure 6-1 Figure 6-2 The two designs of steel plates can change the length, width and height of the interior of the box 1, reduce the consumption of test materials, and make the landslide model more conveniently and quickly.

[0063] Figure 6-3 The detachable side panel of the box body 1 close to the first support frame 3 is modified to facilitate the jack to apply a horizontal load to the push plate 107; Figure 6-4 The push plate 107 is a smooth steel plate, which is slightly smaller in length, width and height than the detachable side plate of the box body 1 near the support frame. During the test, the side plate near the first support frame 3 is first removed and replaced with the push plate 107, and then the soil is loaded. The push plate 107 is supported by a jack in advance, and then the soil is loaded. After loading to a certain extent, the push plate 107 and the jack are mutually stressed. At this time, the bracket 11 of the jack can be removed, or the soil can be continued to be filled. After the slope is built, the bracket 11 can be removed, and the push plate 107 can be pushed by the jack to apply horizontal thrust. It can be based on the model test requirements and Figure 6-1 , Figure 6-2 , Figure 6-3 The side panels can be assembled and used to make the landslide model more conveniently and quickly.

[0064] The present invention integrates horizontal loading, vertical loading and changing the inclination angle of the test box, and can simulate landslide damage under horizontal push loading and landslide damage under vertical loading (slope top loading), saving time and cost. The height and width of the filling in the box can be changed, saving fillers and reducing costs. The box is detachable and the filling material can be reused.

[0065] The steps of using the model test box for simulating landslide damage of the present invention are as follows: 1. Simulate landslide damage ① Open the back side panel of the box 1 and build a base for simulating landslide with appropriate materials.

[0066] ② Close the back side panel of the box body 1, place the base of the jack in the first hoop 6, tighten the screws to fix it, and support it with the bracket 11.

[0067] ③ Remove the side plate of the box body 1 close to the first support frame 3, replace it with a smooth steel plate, fill in an appropriate amount of slope material, and unscrew the jack to support the push plate 107.

[0068] ④Build a complete landslide.

[0069] ⑤ The cross bar 5 on the movable vertical load second support frame 2 is lowered to a suitable position, and the limit piece 8 is tightened to fix it; the jack is installed on the second hoop 9 and the screws are tightened to fix it.

[0070] ⑥ Rotate the handle of the jack and observe the specific conditions of the landslide damage and the sliding surface through the transparent plexiglass plate on the front of the box 1.

[0071] 2. Landslide damage due to changing inclination angle ① Build the required simulated landslide in the box.

[0072] ②Turn on the power 13.

[0073] ③ The motor 401 is controlled by the forward, pause and reverse buttons on the controller 12. The first shaft 407 receives the kinetic energy provided by the motor 401 and transmits the kinetic energy to the second gear 410 through the first gear 408. The second gear 410 drives the second shaft 409 and the winding wheel 403 to rotate, tightening the steel cable, thereby lifting the box.

[0074] ④ Landslide damage. The angle when the box is lifted to the landslide damage can be measured with an electronic level, and the internal friction angle of the slope can be roughly estimated; and the specific conditions of the landslide damage and sliding surface can be observed through the transparent plexiglass plate in front of the box.
