Description

Technical Field

[0001] The invention relates to the field of slope simulation, and in particular to a model device for simulating a wading slope environment and a use method thereof. Background Art

[0002] Slope pre-splitting blasting is a construction technique that reduces the impact of blasting on slope stability by controlling the location and direction of blasting cracks. It is widely used in slope shaping and stability control in transportation, water conservancy, mining, and other projects. Water-related pre-splitting blasting, a key component of this technique, is primarily used in special terrain conditions where the slope is underwater or where the water surface is relatively high above the toe of the slope but lower than the top. This type of blasting requires the placement of pre-splitting holes in complex water-related environments to achieve controlled slope shaping and effectively reduce harmful effects such as blasting vibration and flyrock.

[0003] Compared to conventional pre-splitting blasting of slopes under dry conditions, pre-splitting blasting of water-involved slopes presents greater difficulties in drilling operations. The highly enclosed construction environment, high positioning accuracy requirements, and significant impact of water depth fluctuations on blasting effectiveness make conventional field tests difficult to conduct systematically, limiting in-depth research on blasting mechanisms. To address these issues, physical model testing is currently widely used to simulate the actual working conditions of water-involved slopes, studying the energy propagation patterns, crack propagation characteristics, and optimal hole network parameters during the blasting process. However, in existing pre-splitting blasting models for water-involved slopes, pre-splitting holes are typically set simultaneously during the slope pouring process. That is, before the model material has fully solidified, hole-forming components such as round rods and plastic pipes are manually inserted at predetermined locations to simulate the drilling layout in actual projects. However, this manual hole setting method is subject to significant uncertainty and operational difficulty, which affects the accuracy of subsequent tests. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing models in the prior art, in which the forming of pre-crack holes is usually carried out simultaneously during the slope pouring process, that is, before the concrete is completely solidified, round rods, plastic pipes and other hole-forming components are manually inserted at predetermined positions to simulate the drilling layout in actual engineering projects. However, manual positioning is prone to problems such as hole position offset, hole axis inclination, and depth inconsistency. In addition, the hole-forming components are prone to displacement or deformation during the pouring and vibration process, resulting in difficulty in ensuring the quality of the hole channel, which seriously affects the accuracy of the test simulation. A model device for simulating a wading slope environment and a method for using the same are provided.

The turning seat 4 can also be rotatably connected to the pre-crack hole forming device 5 to adjust the angle of the pre-crack hole during the casting stage.

[0053] The box body 1 is provided with a plurality of drainage holes 11 along its height direction, and some of the drainage holes 11 are connected to the slope casting area 3. A sealing member 6 is provided in the drainage hole 11, which facilitates the subsequent drainage of the box body 1 by removing the corresponding sealing member 6 to simulate the actual water level height of the wading slope, thereby improving the accuracy of subsequent tests.

[0054] In one or more embodiments, a plurality of mounting holes 31 are provided on the side slope casting area 3 and are arranged along the length direction of the box body 1 , so that the side slope casting area 3 and the turning seat 4 are movably connected through the mounting holes 31 ;

In this way, the flip seat 4 can be connected to the slope casting area 3 by connecting the mounting hole 31 and the matching hole 431 with bolts. When the flip seat 4 needs to be moved, the connection between the mounting hole 31 and the matching hole 431 is released, and the flip seat 4 is moved to the mounting hole 31 at the corresponding position and then connected by bolts.

When the flip member 51 does not need to be adjusted, the pawl 422 engages with the teeth of the ratchet 421 to limit the ratchet 421, and the torsion spring 425 connected to the pawl 422 provides a downward pulling force for the pawl 422 to prevent the pawl 422 from being displaced.

[0062] In one or more embodiments, a surface of the outer cover 423 away from the flip member 51 is connected to the bearing seat 41 , and a hole for the rotating shaft 511 to pass through is defined in the outer cover 423 .

[0069] S1. Adjust the pre-crack hole forming device 5 according to the pre-crack hole position and angle predetermined in the test plan;

[0070] Furthermore, specifically, the turning seat 4 is controlled to move the pre-crack hole forming device 5 in the longitudinal direction of the box body 1, thereby adjusting the position of the pre-crack hole, and the pre-crack hole forming device 5 is controlled to be turned over by the turning device 42, thereby adjusting the angle of the pre-crack hole;

[0071] S2, after the pre-crack hole forming device 5 is adjusted, concrete is poured into the slope pouring area 3, and the pre-crack hole forming device 5 and the partition plate 2 are removed after the concrete is initially set;

[0078] Furthermore, the scale is marked with a number of scale marks, wherein the integer scale marks (0, 1, 2, ...) correspond to the center of the mounting hole 31. Specifically, each integer scale mark is vertically aligned with the center of a mounting hole 31, so that when the turning base 4 is moved, the movement distance of the turning base 4 can be quickly and accurately determined by reading the scale marks, further improving the operating efficiency of the simulation device.

[0079] Optionally, the scale can be made of wear-resistant material, such as alloy steel, and the scale markings on the surface of the scale can be laser engraved to avoid wear and unclear scale markings during use.
