Description

Technical Field

[0001] The present application relates to the field of slope instability test equipment, and in particular to a multi-scenario slope stability test device. Background Art

[0002] Slope instability testing refers to a series of methods and experiments to evaluate slope stability, which are used to determine the stability of the slope under the influence of natural factors such as gravity, water pressure, vibration, etc. The purpose of these tests is to predict the time and scale of slope instability and the degree of damage that may be caused, so as to take appropriate prevention and control measures, reduce geological disasters, and ensure the safety and economy of artificial slope design.

[0003] Among them, the slope instability experimental device induced by rainfall is more commonly used. It is an experimental device that simulates the slope instability process under rainfall conditions. This device can simulate the impact of natural rainfall on the slope, study how rainfall causes the slope stability to decrease and eventually leads to disasters such as landslides. This experimental device is of great significance for understanding the impact of rainfall on slope stability, revealing the mechanism of rainfall-induced slope instability, and evaluating the stability of the slope. The traditional experimental device usually includes a model box, that is, a transparent rectangular block with an open top, which is used to construct a slope model and conduct experiments. The slope model is constructed in the model box to simulate the soil structure and characteristics of the actual slope. A rainfall simulation device is constructed above the model box to simulate natural rainfall through a rainfall nozzle and simulate the slope response under different rainfall conditions. In addition, a slope tilt device may be set up to adjust the tilt angle of the model box to simulate the impact of different slopes on slope stability.

[0004] In traditional experimental devices, the way to adjust the slope is relatively simple. Even if the box is tilted as a whole, the simulation of different slopes can be achieved. However, in actual environments, the slopes are often of various types. The most common one is a step state. Further, the step-shaped slope may have different inclinations in each section. When this happens, the use of traditional experimental devices often requires segmented testing, and the overall instability test of the slope cannot be tested, which also leads to insufficient accuracy of the final slope instability test results. Summary of the invention

[0005] In order to solve the problems in the background technology, realize the simulation of slopes in multiple scenarios, and improve the accuracy of slope stability test results, the present application provides a multi-scenario slope stability test device.

[0060] The following is combined with Figure 1-6 This application is described in further detail.

[0061] Embodiment 1,

[0062] The present application provides a multi-scenario slope stability testing device, such as Figure 1 to Figure 2 As shown, it includes a box body 1, a plurality of adjustment plates 2, a plurality of first telescopic plates 3, a vertical plate 4 and a second telescopic plate 5.

[0063] Reference Figure 1 The box 1 constitutes the main structure of the test device, and its bottom surface is a long rectangular structure, and the upper side is open. A rainfall device 11 is arranged above the box 1 to simulate a rainfall environment.

[0064] Reference Figure 1 The rainfall device 11 specifically includes a bracket 111 horizontally arranged above the box body 1. The length direction of the bracket 111 is the same as the length direction of the box body 1. A plurality of drainage pipes 112 are arranged on the lower side of the bracket 111. The plurality of drainage pipes 112 are arranged along the length direction of the bracket 111, and the length direction of each drainage pipe 112 is arranged along the width direction of the bracket 111. A plurality of precipitation holes are opened on the lower side of each drainage pipe 112 in its own length direction, and rain can be simulated to fall on the slope model through these precipitation holes. A main water pipe 113 is fixed on one side of the bracket 111 along its own length direction. One end of the plurality of drainage pipes 112 is connected and fixed to the main water pipe 113, and a control valve is installed on one end of each drainage pipe 112 close to the main water pipe 113, which is used to control the water flow from the main water pipe 113 into the drainage pipe 112, and adjust the water flow as needed to meet different experimental test requirements.

[0065] Reference Figure 2 The length direction of the adjustment plate 2 is arranged along the length direction of the box body 1, and multiple adjustment plates 2 are arranged along the length direction of the box body 1. The side walls of each adjustment plate 2 are sealed against the opposite sides of the box body 1 to ensure the sealing between the side walls of the adjustment plate 2 and the vertical side of the box body 1. A driving mechanism 6 is arranged on the lower side of each adjustment plate 2 to drive the swing or lifting of the adjustment plate 2 to simulate different forms of the slope.

[0066] The first telescopic plate 3 is arranged between adjacent adjustment plates 2. The first telescopic plate 3 is also arranged along the length direction of the box body 1, and the two side walls of the first telescopic plate 3 are also sealed against the opposite sides of the box body 1. The specific structure of the first telescopic plate 3 can be a jacket plate 31, an extension plate 32 and a tension spring. The cross section of the jacket plate 31 is a horizontally arranged U-shaped. The extension plate 32 is sealed and plugged into the socket of the jacket plate 31 and can slide relative to the jacket plate 31. The tension spring is fixed in the socket of the jacket plate 31 and can drag the extension plate 32 to move toward the jacket plate 31. The ends of the jacket plate 31 and the extension plate 32 that are separated from each other are respectively hinged to the ends of the two adjacent adjustment plates 2. In this way, the first telescopic plate 3 can be connected between the adjacent adjustment plates 2 and can be extended and retracted with the swing of the adjacent adjustment plates 2 to compensate for the distance between the adjacent adjustment plates 2.

[0067] For the convenience of illustration, the present embodiment is described by taking the case where two adjustment plates 2 are provided as an example, but in fact the number of adjustment plates 2 can be adjusted according to design requirements.

[0068] Reference Figure 3 and Figure 4 , the vertical plate 4 is vertically arranged in the box body 1, and the two sides of the vertical plate 4 are sealed against the two sides of the box body 1, and the vertical plate 4 is sealed and slid along the length direction of the box body 1. For example, the two sides of the box body 1 can be formed with slide bars in the horizontal direction, and the position of the vertical plate 4 corresponding to the slide bar can be formed with a slide groove. Through the mutual adaptation of the slide bar and the slide groove, the horizontal sliding of the vertical plate 4 relative to the box body 1 is completed. The end of an adjustment plate 2 close to the vertical plate 4 away from the first telescopic plate 3 is also vertically sealed and slid on the vertical plate 4, such as the vertical plate 4 is formed with a vertical groove 41 on one side of the adjustment plate 4 close to the adjustment plate 2, and the position of the adjustment plate 2 corresponding to the vertical groove 41 is hinged with a slider 21, and the slider 21 slides vertically in the vertical groove 41. In this way, the adjustment plate 2 is connected with the vertical plate 4, and when the adjustment plate 2 swings, the slider 21 slides vertically in the vertical groove 41 and cooperates with the horizontal sliding of the vertical plate 4, so that the vertical plate 4 moves synchronously with the adjustment plate 2. In this way, the vertical plate 4 always forms a blocking surface on one side of the slope model, which is convenient for filling the sand mold.

[0069] A second telescopic plate 5 is horizontally arranged at one end of the box body 1 away from the vertical plate 4. The two side walls of the second telescopic plate 5 seal against the opposite sides of the box body 1, and the end of the second telescopic plate 5 away from the vertical plate 4 seals against the end vertical wall of the box body 1.

[0070] The structural form of the second telescopic plate 5 can be the same as that of the first telescopic plate 3, which will not be described in detail here. The second telescopic plate 5 slides vertically on the box body 1. For example, a slide bar is vertically fixed on one side of the box body 1 close to the second telescopic plate 5, and a slide groove adapted to the slide bar is formed on one side of the second telescopic plate 5 close to the box body 1. In this way, the second telescopic plate 5 can slide vertically in the box body 1 through the adaptation of the slide bar and the slide groove.

[0071] The end of an adjustment plate 2 near the end of the box body 1 is hinged to the second telescopic plate 5. In this way, the second telescopic plate 5 can also be extended or moved vertically with the swing of the adjustment plate 2. This configuration allows the second telescopic plate 5 to serve as the last horizontal section of the slope, which is convenient for the stacking of sand molds and the flow of rainwater, thereby more realistically simulating the complete slope shape.

[0072] In summary, by accurately controlling the swing angle of each adjustment plate 2 through the driving mechanism 6 and cooperating with the telescopic function of the first telescopic plate 3 and the second telescopic plate 5, various forms of slope shape simulation can be achieved. Then, the rainfall device 11 is used to simulate rainfall, which can be used for slope instability testing.

[0073] Reference Figure 3 and Figure 5 The driving mechanism 6 is described in detail below. The driving mechanism 6 includes a base 61, a T-shaped swing rod 62, and an L-shaped swing rod 63. The bases 61 are arranged symmetrically on both sides of the length direction of the box body 1. The length direction of the base 61 is arranged along the length direction of the box body 1. Two connecting parts are arranged on the base 61 along the length direction thereof, which are herein referred to as a first connecting part 611 and a second connecting part 612.

[0074] The T-shaped swing arm 62 includes a horizontal portion and a vertical portion vertically fixed to the center of the horizontal portion, and the distance from the two ends of the horizontal portion to its center is the same as the distance from the vertical portion to the center of the horizontal portion, that is, the position where the vertical portion and the horizontal portion are level is the center of the T-shaped swing arm. The center of the T-shaped swing arm 62 is hinged to the first connection portion 611 of the base 61, and the end of the base 61 close to the first connection portion 611 is hinged to the first telescopic cylinder 64, and the telescopic rod of the first telescopic cylinder 64 is connected to the horizontal end of the T-shaped swing arm 62. The lower surface of the adjustment plate 2 is vertically fixed with a fixed rod 22 at the position corresponding to the T-shaped swing arm 62, and the lower end of the fixed rod 22 is hinged to the horizontal end of the T-shaped swing arm 62. When the first telescopic rod is extended and retracted, it can drive the T-shaped swing arm 62 to swing, thereby pushing or dragging the fixed rod 22 to move synchronously to drive the adjustment plate 2 to move.

[0075] The L-shaped swing arm 63 includes a horizontal portion and a vertical portion perpendicular to each other, and the length of the horizontal portion is the same as that of the vertical portion, that is, the intersection of the horizontal portion and the vertical portion is the center position of the L-shaped swing arm 63. The center position of the L-shaped swing arm 63 is hinged to the second connecting portion 612 of the base 61, and a second telescopic cylinder 65 is arranged between the T-shaped swing arm 62 and the L-shaped swing arm 63. The cylinder body of the second telescopic cylinder 65 is hinged to one end of the vertical portion of the T-shaped swing arm 62, and the telescopic rod of the second telescopic cylinder 65 is intersected to one end of the vertical portion of the L-shaped swing arm 63. A movable rod 23 is vertically arranged at a position corresponding to the L-shaped swing arm 63 on the lower surface of the adjustment plate 2, and the movable rod 23 has the same length as the fixed rod 22. The upper end of the movable rod 23 is hinged to the adjustment plate 2, and the lower end of the movable rod 23 is hinged to the horizontal end of the L-shaped swing arm 63.

[0076] When the first telescopic cylinder 64 is extended and the second telescopic cylinder 65 remains in its original state, the first telescopic cylinder 64 extends to drive the T-shaped swing rod 62 to swing to a vertical state, and then the second telescopic rod that remains in its original state is linked to the L-shaped swing rod 63, so that the fixed rod 22 and the movable rod 23 can be simultaneously pushed to swing upward, so that the adjustment plate 2 is swung and lifted, even if the position of the adjustment plate 2 placed on the L-shaped swing rod 63 is at a high point, and then the second telescopic cylinder 65 is extended and extended to drive the L-shaped swing rod 63 to move alone, and the movable rod 23 can be used to drive the adjustment plate 2 located at one end of the L-shaped swing rod 63 to swing downward until the adjustment plate 2 reaches the maximum inclination, and at the same time, the first telescopic cylinder 64 will swing and extend with the adjustment rod to ensure that the action of the adjustment plate 2 is completed. Of course, by driving the first telescopic cylinder 64 and the second telescopic cylinder 65 to extend or contract different distances respectively at the same time, the adjustment plate 2 can also complete the swing at different angles to achieve the simulation of various slope forms.

[0077] In summary, the implementation principle of the present application is: by accurately controlling the swing angle of each adjustment plate 2 through the driving mechanism 6, and cooperating with the telescopic function of the first telescopic plate 3 and the second telescopic plate 5, various forms of slope shape simulation can be realized. The vertical plate 4 moves horizontally with the swing of the adjustment plate 2 to form a stable blocking surface. The rainfall device 11 can simulate a real rainfall environment, thereby conducting a comprehensive and accurate test of the slope stability. This multi-scenario slope stability test device not only improves the accuracy of the test, but also enhances the flexibility and practicality of the experiment.

[0078] Embodiment 2,

[0079] Reference Figure 6 , a multi-slope stability testing device, compared with embodiment 1, is adapted to the simulation of more slope forms. A distance adjusting cylinder 66 is arranged between the bases 61 on the lower sides of adjacent adjustment plates 2, and the cylinder body and telescopic rod of the distance adjusting cylinder 66 are respectively hinged to the adjacent ends of the two bases 61. Two lifting cylinders 67 are vertically fixed to the lower side of the base 61, and the telescopic rods of the lifting cylinders 67 are arranged downward and rotatably provided with pulleys 671. Tracks 613 are also fixed on both sides of the base 61 along the length direction of the base 61, which are used to limit the pulleys 671 from being able to move along the tracks 613. A horizontally arranged locking cylinder 68 is also fixed inside at least one distance adjusting cylinder 66, and the length direction of the locking cylinder 68 is arranged along the width direction of the base 61. The telescopic rod of the locking cylinder 68 faces the side wall of the box body 1, and the telescopic rod of the locking cylinder 68 extends to contact the side wall of the box body 1, thereby limiting the relative position of the base 61 and the box body 1.

[0080] With the above arrangement, the lifting cylinder 67 can be extended and retracted to drive the base 61 to move vertically, and the adjustment cylinder can be extended and retracted to push the two bases 61 to slide, thereby adjusting the distance between the two adjustment plates 2. After the adjustment is completed, the locking cylinder 68 drives the telescopic rod to extend, so that the end of the telescopic rod contacts the side wall of the box body 1 to achieve the locking of the base 61. In this way, it can adapt to more forms of slope simulation.

These elastic sealing films can effectively seal each hinged portion, further reduce the possibility of leakage, and ensure the accuracy and reliability of the experiment.
