Abstract
Description
Technical Field
[0001] This invention relates to the field of geotechnical engineering physical simulation technology, and in particular to a material preparation machine for constructing a model of a bedding rock slope with foliation structure. Background Technology
[0002] Foliar rocks of regional metamorphic origin are widely found in nature. These rocks contain oriented platy minerals, forming a foliated structure with primary weak structural planes such as platy, foliated, and gneissic surfaces. Controlled by these mechanically weak primary structural planes, foliated rocks often constitute landslide-prone rock formations, giving rise to surface geological hazards. In recent years, with the accelerating pace of transportation and water conservancy construction, linear projects such as highways, railways, and reservoirs have continuously extended into mountainous areas. Intensive human engineering activities have shaped and generated numerous rock slopes, whose stability has become a prominent challenge in engineering safety and disaster prevention and mitigation. Fissured rock slopes composed of foliated rocks are prone to overall sliding along foliated structural planes under the influence of external factors such as rainfall and human engineering activities. Some large rock landslides, due to their sliding characteristics along weak rock surfaces, are characterized by suddenness, high concealment, large scale, and high speed and long distance, often severely damaging infrastructure and causing significant casualties and economic losses. They are a top priority for national geological disaster prevention and control.
[0003] A thorough understanding of the failure mechanism of bedding rock slopes and the development of precise prediction methods are key prerequisites for effective disaster prevention and mitigation. Physical model tests, as the core means of verifying theories and revealing mechanisms, can dynamically reproduce the entire process of landslides from initiation and sliding to deposition, thus providing a solid empirical foundation for clarifying the failure mechanism and optimizing prevention and control measures.
[0004] The core challenge of physical model tests for bedding rock slopes lies in the fabrication of materials that are structurally equivalent to the rock mass. Due to the discrete nature of natural rock materials in terms of porosity, composition, and foliation dip angle, test results are typically highly discrete, uncontrollably impacting the analysis of the mechanical behavior and failure mechanisms of bedding rock slopes. Therefore, by leveraging the controllable homogeneity of similar materials and controlling both the composition and foliation dip angle, fabricated foliated structurally similar materials are of significant practical value for effectively revealing the failure mechanisms of bedding rock slopes and optimizing prevention and control strategies through physical model tests. Summary of the Invention
[0005] The purpose of this invention is to provide a material preparation machine for constructing models of bedding rock slopes with foliation structures. By setting a telescopic rod-type angle adjustment mechanism between the base and the support platform, combined with the rotational cooperation of the ear plate and connecting block, the tilt angle of the support platform can be precisely adjusted to match the bedding requirements of bedding slopes with different dip angles. An integrated horizontal and lateral moving material distribution mechanism, relying on the cooperation of multi-stage servo motors, unidirectional lead screws, and guide rods, combined with a hopper impeller and gear rack, sprocket, and chain linkage assembly, achieves precise spatial displacement of the hopper and uniform material distribution, accurately replicating the characteristics of the bedding interface.

[0032] Working principle: The first template 22 and the second template 23 are placed on the support platform 3. The first connecting screw 24 and the second connecting screw 25 are respectively passed through the template through the through hole and screwed into the threaded hole of the support platform 3 for fixation. Then, the third connecting screw 26 is passed through the through hole in the side wall of the first template 22 and connected to the threaded hole of the second template 23 to achieve a firm splicing and sealing between the first template 22 and the second template 23. After the formwork is completed, take cement and mica flakes, mix the cement and mica flakes evenly, and then add water while stirring. After the mixture is evenly mixed, pour it into the hopper 9. At the same time, start the power supply through the controller to regulate the coordinated operation of each component. The controller controls the first servo motor 14 to work, and its output shaft drives the second sprocket 15 to rotate. The first chain 13 drives the two first sprockets 12 and the first one-way screw 10 to rotate synchronously, so that the first slider 4 sleeved on the first one-way screw 10 drives the base 2 and the support platform 3 to move horizontally along the slide rail 1 to the designated pouring position directly below the hopper 9. Then, the second servo motor 40 is activated to adjust the height of the crossbeam 8, and the third servo motor 44 is activated to adjust the lateral position of the hopper 9, so that the hopper 9 is aligned with the pouring area. At the same time, the linkage components operate. When the hopper 9 moves with the fourth slider 32, the gear 47 meshes with the rack 49 on the top surface of the crossbeam 8 and rotates. Through the connecting shaft 50, the fifth sprocket 51 is driven, and then through the third chain 52, the fourth sprocket 46 and impeller 34 are driven to rotate, so that the material in the hopper 9 is evenly poured into the formwork area. At the same time, the pouring surface is smoothed by the screed plate on the bottom surface of the hopper 9. After one layer of material is poured, the hopper 9 is raised and the previous steps are repeated until the formwork mechanism is filled. During the pouring process, external vibration equipment can be used to vibrate and compact the material. The layered pouring of the mixed material and the layer thickness being less than the radius of the mica sheet ensure that the mica sheet can be mixed evenly and distributed in a horizontal trend, ensuring a dense layered structure. After the pouring is completed, the controller controls the first servo motor 14 to run in reverse, so that the support platform 3 moves away from the hopper 9 area along the slide rail 1, allowing the model to naturally take shape in the formwork support mechanism; After finalization, based on the required bedding angle of the bedding rock slope, the controller adjusts the extension and retraction of the telescopic rod 17. Relying on the pin-hinged connection between the second connecting ear plate 18 and the second connecting block 19, and the third connecting ear plate 20 and the third connecting block 21, the bearing platform 3 is driven to rotate around the hinge point of the first connecting ear plate 5 and the first connecting block 6, adjusted to the preset tilt angle and maintained rigid support, and finally completed the construction of the bedding rock model with foliation structure, preparing for the subsequent production of the slope model.
