Technical Field
[0001] This application relates to the field of rock mass model making technology, specifically a column-type dangerous rock mass model making device. Background Art
[0002] Pillar-shaped unstable rock masses are a typical geological hazard in mountainous areas, often standing upright on steep cliffs or deeply incised riverbanks. They are generally distributed in the core or near-core areas of folds, with gently dipping strata (less than 10°), primarily composed of thick-layered clastic rocks and carbonate rocks, such as hard rocks like sandstone, limestone, and dolomite, as well as claystone, exhibiting a slope structure with alternating layers of hard and soft rock, or a hard upper layer and soft lower layer. Typically, due to the steep dipping structure in the core area of folds, the rock mass slope undergoes gradual deformation under the long-term action of gravity and external forces, and the controlling structural planes around the periphery gradually unload and connect, forming columnar, single unstable rock masses. When a pillar-shaped unstable rock mass located in a steep cliff area becomes unstable, its potential energy converts into extremely high kinetic energy. During the process of instability, collision, and migration, the unstable rock mass gradually topples and disintegrates, forming a high-speed, long-range debris flow, seriously threatening human life and property. Pillar-shaped unstable rock masses located on both banks of a river valley, once destabilized, can easily spill into the river, triggering secondary disasters such as surges and floods, forming a disaster chain and seriously threatening the safety of navigation. Therefore, the failure mechanism and stability of pillar-shaped unstable rock masses have always been an important focus in geological hazard research. In order to scientifically analyze the failure mechanism and stability of pillar-shaped unstable rock masses, it is necessary to conduct physical model experiments to study their failure mechanism and stability.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] It should be noted that in the description of this application, the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0029] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.
[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.
[0031] It should be clear that before understanding the embodiments of this application, it is necessary to understand that the semi-finished product of the column-type unstable rock mass model 6 produced by the manufacturing device proposed in the embodiments of this application is as follows: Figure 7 As shown, a fracture layer 61 is formed in the middle of the column-type unstable rock mass model 6. The fracture layer 61 in the column-type unstable rock mass model 6 divides the model into a first part and a second part, as shown in the figure. Figure 7 As shown, the first part has multiple rock strata gaps 63 and multiple gaps between unstable rock pillars 64, which divide the first part into multiple unstable rock masses 65. Figure 7 As shown, the column-type unstable rock mass model 6 also has a rock mass slope 62. It is easy to understand that the various unstable rock masses 65 in the first part are prone to collapse and disintegrate along the rock mass slope 62. The finished product of the column-type unstable rock mass model 6 is shown below. Figure 8 As shown, after each unstable rock mass 65 is disintegrated along the rock mass slope 62, a finished column-type unstable rock mass model 6 is formed.
[0032] It is easy to understand that the above-mentioned column-type unstable rock mass model 6 finished product (such as...) Figure 8As shown, manual fabrication of a rock mass model is difficult, requires a high level of skill from the workers, and is inefficient. To address this technical problem, this application proposes a column-type unstable rock mass model fabrication device, which includes a fabrication platform 1, a friction assembly 2, and a fabrication frame 3. Specifically, as shown... Figure 1 As shown, the friction assembly 2 is mounted on the manufacturing platform 1. Figure 2 As shown, the friction assembly 2 includes a fabrication plane 231, which is parallel to a horizontal plane and is movable along a first direction. In the embodiments of this application, the first direction is also known as... Figure 1 , Figure 2 , Figure 7 and Figure 8 Direction A in the middle will not be elaborated further. For example... Figure 1 As shown, the frame 3 is positioned directly above the fabrication plane 231, forming an area for fabricating the column-type unstable rock mass model 6. When the fabrication plane 231 moves along the first direction, the frame 3 restricts the movement of the column-type unstable rock mass model 6 along the first direction.
[0033] In use, firstly, create the following in the production area formed by production frame 3 and production plane 231: Figure 7 The semi-finished column-type unstable rock mass model 6 is shown. Then, the fabrication plane 231 is moved along the first direction. The semi-finished column-type unstable rock mass model 6 cannot move along the first direction due to the constraint of the fabrication frame 3. Because there is friction between the semi-finished column-type unstable rock mass model 6 and the fabrication plane 231, the first part of the semi-finished column-type unstable rock mass model 6 can move as shown under the action of friction. Figure 8 As shown, the rock mass slope 62 collapsed and disintegrated, eventually forming a column-shaped unstable rock mass model 6.
[0034] It should be clear that, in the embodiments of this application, it is only necessary to manufacture as follows: Figure 7 The semi-finished column-type unstable rock mass model 6 shown can be further processed by moving the fabrication plane 231 along the first direction to obtain the finished column-type unstable rock mass model 6. Compared to obtaining the finished column-type unstable rock mass model 6 by hand, this application only requires the semi-finished column-type unstable rock mass model 6 to be fabricated by hand. Obviously, compared to hand-making such as Figure 8 The finished product shown is handmade. Figure 7 The semi-finished products shown are simpler, easier to produce, and more efficient to manufacture.
[0035] It should be clear that in the embodiments of the present application, the friction component 2 can be any component having a production plane 231 that can move in the first direction. For example, in an embodiment of the present application, the friction component 2 can be a conveyor belt, and any plane parallel to the horizontal plane on the conveyor belt can be used as the production plane 231. Or the friction component 2 can be a bottom friction tester. To reduce the use cost, the friction component 2 can only have a friction belt 23 as shown in Figure 2 . The production plane 231 is arranged on the friction belt 23. During use, the friction belt 23 can be manually dragged to move in the first direction so that the production plane 231 moves in the first direction. In this embodiment, in order to be able to automatically control the movement of the friction belt 23 in the first direction, the friction component 2 can further include a first driving member 24, a first roller 21 and a second roller 22. Among them, as shown in Figure 2 , the first roller 21 and the second roller 22 are arranged in sequence in the first direction, and both the first roller 21 and the second roller 22 are rotationally connected to the production platform 1. One end of the friction belt 23 is connected to the first roller 21, and the other end of the friction belt 23 is wound around the second roller 22. The first driving member 24 is used to drive the first roller 21 to rotate. During use, the first driving member 24 drives the first roller 21 to rotate. Further, the rotating first roller 21 winds the friction belt 23 around the first roller 21 body. Further, the friction belt 23 drives the second roller 22 to rotate. During this process, the production plane 231 located on the friction belt 23 moves in the first direction.
[0036] It should be clear that in the embodiments of the present application, since the production frame 3 is mainly used to form a production area for manufacturing the columnar dangerous rock mass model 6 with the production plane 231, the production frame 3 can be any frame structure that can form an area for manufacturing the columnar dangerous rock mass model 6 with the production plane 231. For example, in an embodiment of the present application, the production frame 3 can be a square frame in the shape of a "mouth" (not shown in the figure); it can also be a frame in the shape of a "匚" as shown in Figure 3 and Figure 4 .
[0037] In an embodiment of the present application, the production frame 3 can include a first frame bar 31, a second frame bar 32 and a third frame bar 33. Among them, the extending direction of the first frame bar 31 is perpendicular to the first direction. The extending directions of the second frame bar 32 and the third frame bar 33 are both parallel to the first direction. The second frame bar 32 is arranged at the first end of the first frame bar 31, and the third frame bar 33 is arranged at the second end of the first frame bar 31. As shown in Figure 3 , the first frame bar 31, the second frame bar 32 and the third frame bar 33 can be an integrally formed structure or a welded and fixed structure. To facilitate controlling the size of the production frame 3 so as to manufacture columnar dangerous rock mass models 6 of different sizes with the production frame 3, the production frame 3 can also be as shown in Figure 4As shown, the first frame strip 31, the second frame strip 32, and the third frame strip 33 form a detachable connection. To facilitate the disassembly and installation of the second frame strip 32 and the third frame strip 33, as shown... Figure 1 As shown, the second frame bar 32 and the third frame bar 33 can form a threaded connection with the manufacturing platform 1.
[0038] In use, the second frame strip 32 and the third frame strip 33 are used to limit the overall width of the column-type unstable rock mass model 6, and the first frame strip 31 is used to limit the movement of the column-type unstable rock mass model 6 along the first direction. To enable the frame 3 to be adapted to friction strips 23 of different thicknesses, in one embodiment of this application, such as... Figure 4 As shown, the first frame strip 31 forms a sliding connection with the second frame strip 32 and the third frame strip 33 in the vertical direction. The first frame strip 31 is also provided with at least one elastic element 34. The elastic element 34 stores elastic potential energy, which is used to make the first frame strip 31 have a tendency to move vertically downward. That is, in this embodiment, under the action of the elastic element 34, the first frame strip 31 can form elastic contact with friction strips 23 of different thicknesses in the vertical direction. This avoids the gap between the first frame strip 31 and the friction strip 23 being too large, which would cause a part of the column-type unstable rock mass model 6 to be carried away through the gap.
[0039] It needs to be clear that, such as Figure 7 As shown, during the fabrication of the column-type unstable rock mass model 6, it is necessary to keep the top surface of the column-type unstable rock mass model 6 flat. In order to facilitate the operator in flattening the top surface of the column-type unstable rock mass model 6, in the embodiments of this application, the fabrication device may further include a leveling component 4, which is used to smooth the top surface of the column-type unstable rock mass model 6.
[0040] In the embodiments of this application, the leveling component 4 can be any component capable of leveling the top surface of the column-shaped unstable rock mass model 6. For example, the leveling component 4 can be a trowel. Specifically, a trowel is a tool used for applying paint or plaster, its main function being to help construction workers apply or plaster more evenly, thereby improving construction efficiency and work quality. Since trowels are a mature technology, they will not be described in detail here. Alternatively, the leveling component 4 can include a sliding strip 41 and a leveling strip 42. Wherein, as... Figure 5 and Figure 6 As shown, the slider 41 and the frame 3 form a sliding connection along the second direction, as shown in the diagram. Figure 6 As shown in direction B, direction B is parallel to the horizontal plane. The leveling strip 42 is set on the sliding strip 41 and is used to level the top surface of the column-type unstable rock mass model 6. In use, the leveling strip 42 is moved along the second direction once or multiple times to level and compact the top surface of the column-type unstable rock mass model 6, which is convenient and quick.
[0041] It is important to understand that during the fabrication of the column-type unstable rock mass model 6, in order to avoid excessive internal stress and cracks during the consolidation process, which could affect subsequent test results, it is necessary to lay the model layer by layer until the column-type unstable rock mass model 6 is formed. It is also important to understand that, in the embodiments of this application, "layer by layer" means, assuming as... Figure 7 The thickness of the column-type unstable rock mass model 6 shown (thickness direction perpendicular to the paper surface) is 10mm. Therefore, only a 2mm thick layer is laid each time. After 5 layings, a column-type unstable rock mass model 6 with a thickness of 10mm can be obtained.
[0042] In the process of laying the column-type unstable rock mass model 6 layer by layer, in order to prevent the leveling strip 42 from damaging the top surface of each layer, the leveling strip 42 also includes a leveling surface 421. Specifically, in this embodiment, the leveling surface 421 refers to the surface on the leveling strip 42 that contacts the top surface of each layer in the column-type unstable rock mass model 6 during the leveling process. Figure 6 As shown, the dihedral angle formed by the scraping plane 421 and the horizontal plane 5 (i.e., as shown) Figure 6 Angle C) shown is an acute angle. It's important to understand that the dihedral angle formed by the scraping plane 421 and the horizontal plane 5 is acute. This means that during the smoothing process, the scraping plane 421 will more closely and precisely adhere to the top surface of each layer in the column-type unstable rock mass model 6. This precise fit helps reduce gaps or unevenness caused by the tool's shape, thus making it easier to achieve a smooth top surface on the column-type unstable rock mass model 6.
[0043] As mentioned above, the production of the column-type unstable rock mass model 6 requires layer-by-layer stacking. Each stacking process necessitates smoothing the top surface. To enable the smoothing strip 42 to smooth the top of the semi-finished column-type unstable rock mass model 6 of varying thicknesses, the sliding strip 41 is equipped with a second driving component 43. This second driving component 43 drives the smoothing strip 42 to reciprocate vertically. In use, the second driving component 43 can be used to adjust the smoothing strip 42 to a suitable height, allowing it to smooth the top surface of the semi-finished column-type unstable rock mass model 6 of corresponding thicknesses.
[0044] In embodiments of this application, the second driving member 43 can be any component capable of driving the scraping strip 42 to reciprocate in the vertical direction. For example, the second driving member 43 can be an electric push rod or a hydraulic push rod. In one embodiment of this application, such as Figure 6 As shown, the second driving component 43 can be a threaded rod, which is threadedly connected to the leveling strip 42. Rotating the threaded rod in either the forward or reverse direction will cause the leveling strip 42 to move vertically downward or vertically upward. In this embodiment, the threaded rod can be manually driven to rotate, or a motor can be used to drive the threaded rod to rotate. To ensure the operator can clearly see the position of the leveling strip 42, additional features can be added... Figure 5 As shown, a scale bar 44 is provided on the slider 41, which is used to indicate the position of the scraping bar 42.
[0045] In the embodiments of this application, a columnar unstable rock mass model 6 can be made using materials similar to or the same as the geological conditions to be studied. To ensure the material closely resembles the texture of real rock, in one embodiment of this application, barite powder, quartz sand, and paraffin oil can be mixed. Paraffin oil has low strength, stable properties, and good hydrophilicity, making it suitable for material bonding. Furthermore, paraffin oil is reusable, saving on experimental costs.
[0046] As can be seen from the foregoing, in the embodiments of this application, since the main function of the manufacturing platform 1 is to install and support components such as the friction assembly 2 and the leveling assembly 4, the manufacturing platform 1 only needs to achieve the above functions, and its shape and structure are not limited in any way. For example, in the embodiments of this application, the manufacturing platform 1 can be a square platform formed by stacking cement, or a circular platform formed by welding steel, etc.
[0047] It should be understood that the fabrication apparatus proposed in this application, through the arrangement of the friction component and the fabrication frame, enables workers to quickly fabricate a column-shaped unstable rock mass model based on the friction component and the fabrication frame. This fabrication apparatus not only reduces the skill requirements for workers fabricating column-shaped unstable rock mass models, but also improves the fabrication efficiency of column-shaped unstable rock mass models.
[0048] Specifically, the fabrication of the column-type unstable rock mass model 6 using the fabrication device proposed in the embodiments of this application includes steps S100 to S500.
[0049] Step S100: Weigh out appropriate amounts of barite powder, quartz sand and paraffin oil, mix them evenly, divide them into two portions, and dye the two portions of materials with different colors to obtain a first mixed material and a second mixed material with different colors.
[0050] In the embodiments of this application, barite powder, quartz sand and paraffin oil can be mixed in any proportion as required, which will not be elaborated here.
[0051] Step S200: Fill the production area formed by the production frame 3 and the production plane 231 with the first mixed material; then use the scraper component 4 to smooth and compact the first material.
[0052] Step S300: Repeat step S200 above until the thickness of the column-type unstable rock mass model 6 reaches the design thickness.
[0053] It is important to understand that the main purpose of step S300 is to avoid the impact of internal cracks in the column-type unstable rock mass model 6 on the test results through multiple layers of laying; this will not be elaborated upon here. The thickness of the column-type unstable rock mass model 6 and the thickness of the first layer of mixed material laid in each layer can be set according to requirements.
[0054] It is important to understand that after step S300 is completed, the friction component 2 is slightly rotated until the belt rotates but the model remains unchanged. This step, together with compaction, allows the semi-finished model to solidify and completes the stress redistribution of the model.
[0055] Step S400: Using a tool (such as a utility knife), cut out the following on the column-type unstable rock mass model 6: Figure 7 The fractured layer 61, rock slope 62, rock stratum gap 63, and dangerous rock pillar gap 64 are shown; and the fractured layer 61 is filled with a second mixed material until the second mixed material reaches the designed thickness.
[0056] It is important to understand that any excess first mixed material formed during the trimming of the fracture layer 61 and the rock slope 62 in this step needs to be cleaned up. The thickness of the second mixed material can be equal to or less than the thickness of the column-type unstable rock mass model 6.
[0057] Step S500: Move the creation plane 231 to make it as follows Figure 7 The unstable rock mass 65 shown is capable of base buckling, followed by toppling and failure, thus forming a structure like... Figure 8 The column-type unstable rock mass model shown is 6.
[0058] It is important to understand that in this step, the movement of plane 231 will not be stopped until each of the unstable rock masses 65 has fractured and stabilized, so as to ensure the complete destruction process of the column-type unstable rock mass model 6.
[0059] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
