Description

Technical Field

[0001] This utility model relates to the field of slope simulation, and in particular to a model device for simulating the environment of a water-eroded slope. Background Technology

[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, and mining projects. As an important component, pre-splitting blasting for water-related slopes is mainly applied in special terrain conditions where the slope is underwater or the water level is relatively higher than the slope toe but lower than the slope crest. This type of blasting requires the placement of pre-splitting holes in complex water-related environments to achieve slope surface shaping control and effectively reduce harmful effects such as blasting vibration and flyrock.

[0003] Compared to pre-splitting blasting of slopes under conventional dry conditions, pre-splitting blasting of water-strewn slopes presents greater challenges in drilling operations. The construction environment is highly enclosed, requiring high positioning accuracy, and changes in water depth significantly impact the blasting effect. Conventional field tests are difficult to conduct systematically, limiting in-depth research into the blasting mechanism. To address these issues, current methods often employ physical model testing to simulate the actual working conditions of water-strewn slopes, studying energy propagation patterns, crack propagation characteristics, and optimal borehole parameters during the blasting process. However, in existing pre-splitting blasting models for water-strewn slopes, the setting of pre-splitting holes is usually carried out simultaneously during slope pouring. That is, before the model material has fully solidified, borehole-forming components such as round rods or plastic pipes are manually inserted at predetermined locations to simulate borehole layout in actual engineering. However, this manual hole-setting method involves significant uncertainty and operational difficulty, thus affecting the accuracy of subsequent tests. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing models in the prior art, where the formation of pre-splitting holes is usually carried out simultaneously during the slope pouring process. That is, before the concrete has fully solidified, hole-forming components such as round rods and plastic pipes are manually inserted into predetermined positions to simulate the drilling layout in actual engineering. However, manual positioning is prone to problems such as hole position displacement, hole axis tilting, and inconsistent depth. Furthermore, the hole-forming components are prone to displacement or deformation during pouring and vibration, making it difficult to guarantee the quality of the duct and seriously affecting the accuracy of the experimental simulation. This invention provides a model device for simulating the environment of a water-eroded slope.

[0005] In a first aspect, the present invention provides a model device for simulating a water-eroded slope environment, comprising: a box and a partition plate, wherein the box is capable of dividing its internal cavity into a slope pouring area through the partition plate, and a flipping seat is movably connected to the side plate of the slope pouring area, the flipping seat being configured to move toward or away from the partition plate.

[0006] The slope pouring area is connected to a pre-splitting hole forming device via the flipping seat, and the pre-splitting hole forming device can be flipped within the slope pouring area via the flipping seat.

[0007] The box body has several drainage holes along its height, and the drainage holes can be fitted with sealing components.

[0008] This invention provides a model device for simulating a water-eroded slope environment. A partition plate divides the interior of the container into slope casting areas. A rotating seat, movable towards or away from the partition plate, is installed within these areas. A pre-splitting hole forming device is connected to this rotating seat. This simulation device allows for the determination of pre-splitting hole positions during the initial testing phase. Moving the rotating seat moves the pre-splitting hole forming device within the slope casting area, thereby adjusting the axial position of the pre-splitting holes. The rotation of the rotating seat and the pre-splitting hole forming device causes the device to rotate. This allows for the adjustment of the pre-splitting hole's forming angle on the flooded slope. Compared to traditional test simulation devices where pre-splitting holes are manually set during the subsequent slope pouring stage, this invention allows for adjustment of the pre-splitting hole's forming position and angle in the early stages of pouring, improving test efficiency and subsequent test accuracy. Furthermore, the simulation device of this invention is equipped with several drainage holes and sealing components along the height of the casing. By setting these drainage holes and sealing components, the water level within the simulation device can be controlled according to the actual needs of the flooded slope during the test, more accurately replicating the on-site conditions and improving test accuracy.

[0009] Preferably, the slope pouring area is provided with a plurality of mounting holes, and the flipping seat is movably connected to the slope pouring area through the mounting holes and can move toward or away from the partition plate.

[0010] By setting several mounting holes in the slope pouring area, the flipping seat can be connected to the slope pouring area through the mounting holes, which improves the connection stability between the flipping seat and the slope pouring area and reduces the risk of the flipping seat shifting again after the pre-cracked hole forming device is axially positioned, resulting in positioning failure.

[0011] Preferably, a scale is provided on the slope pouring area along the length of the box, and the integer scale on the scale is aligned with the center of the corresponding mounting hole.

[0012] The use of a scale and mounting holes allows test personnel to more intuitively see the position of the pre-splitting hole forming device.

[0013] Preferably, the flipping seat includes a bearing seat, and the side of the bearing seat facing the cavity of the slope pouring area is provided with a flipping device, and the flipping device is rotatably connected to the pre-cracked hole forming device.

[0014] The rotating connection between the flipping device and the pre-cracked hole forming device allows the pre-cracked hole forming device to be flipped, making it convenient for subsequent testers to adjust the angle of the pre-cracked hole forming device according to design requirements.

[0015] Preferably, the flipping device includes a ratchet, and the flipping device further includes a pawl that cooperates with the ratchet.

[0016] Preferably, the flipping device further includes a housing, inside which is a mounting base. One end of the pawl is rotatably connected to the mounting base, and a torsion spring is also provided on the pawl. One end of the torsion spring is connected to the pawl, and the other end is connected to the mounting base.

[0017] Preferably, the pre-cracked hole forming device includes a flipping component, on which a rotating shaft is provided, the rotating shaft passing through the ratchet and being movably connected to the bearing seat.

[0018] Preferably, the flipping component has a vertical through hole, and the flipping component is movably connected to a plurality of pre-cracked hole molds through the through hole.

[0019] By connecting the pre-cracked hole mold and the flipping part through a through hole, the pre-cracked hole mold can move axially on the flipping part, thereby controlling the depth of the pre-cracked hole after molding and making the subsequent tests more accurate. By setting the rod and the flipping part to be movably connected, the rod and the flipping part can be disassembled. When the rod is worn, it can be removed and replaced directly.

[0020] Preferably, the pre-cracked hole mold includes a rod that is adapted to the through hole, and a pair of limiting nuts are sleeved on the rod to restrict the axial movement of the rod within the through hole.

[0021] The rod and the flipping part are movably connected, so that the forming depth through the pre-cracked hole is adjustable. A pair of limit nuts are set on the rod so that when the rod is adjusted to the design position, the limit nuts can clamp the flipping part to limit the rod.

[0022] Preferably, the rod is provided with a threaded part, and the rod is connected to the limiting nut through the threaded part.

[0023] Preferably, the drain hole is provided with internal threads, the body of the sealing component is a sealing bolt, and a sealing ring is provided at the end of the sealing bolt facing the drain hole.

[0024] Preferably, the partition plate includes a horizontally arranged horizontal plate, one end of which is connected to the inner wall of the box and the other end is connected to an inclined plate. A support member is provided on the side of the inclined plate away from the slope pouring area. One end of the support member is connected to the inclined plate and the other end is connected to the inner wall of the box.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. This utility model provides a model device for simulating a water-eroded slope environment. A partition plate divides the slope casting area within a box, and a rotating seat that can move towards or away from the partition plate is installed on the slope casting area. A pre-splitting hole forming device is connected to this rotating seat. This simulation device allows for the determination of the pre-splitting hole position in the initial stage of the experiment. By moving the rotating seat, the pre-splitting hole forming device is moved within the slope casting area, thereby adjusting the axial position of the pre-splitting holes. The rotation of the rotating seat and the pre-splitting hole forming device causes the pre-splitting hole forming device to rotate. This allows for the adjustment of the pre-splitting hole's forming angle on the flooded slope. Compared to traditional test simulation devices where pre-splitting holes are manually set during the subsequent slope pouring stage, this invention allows for adjustment of the pre-splitting hole's forming position and angle in the early stages of pouring, improving test efficiency and subsequent test accuracy. Furthermore, the simulation device of this invention also features several drainage holes and sealing components along the height of the casing. By using these drainage holes and sealing components, the water level within the simulation device can be controlled according to the actual needs of the flooded slope during the test, more accurately replicating the on-site conditions and improving test accuracy.

[0043] Example 1

[0044] like Figure 1 , Figure 2 and Figure 7As shown, a model device for simulating a water-eroded slope environment includes a box 1 for simulation. The box 1 is equipped with a partition plate 2, which divides the slope pouring area 3 within the box 1. The box 1 is also equipped with a rotating seat 4 that can move along its own length. The rotating seat 4 is located at the top of the slope pouring area 3. The rotating seat 4 is rotatably connected to a pre-cracked hole forming device 5. By rotatably connecting the pre-cracked hole forming device 5 to the rotating seat 4, the simulation device can form pre-cracked holes during subsequent experimental pouring. The rotating seat 4 can drive the pre-cracked hole forming device 5 to move, thereby determining the position of the pre-cracked hole. The angle of the pre-cracked hole can also be adjusted during the pouring stage through the rotatable connection between the rotating seat 4 and the pre-cracked hole forming device 5.

[0045] The box 1 has several drainage holes 11 along its height direction, and some of the drainage holes 11 are connected to the slope pouring area 3. The drainage holes 11 are equipped with sealing parts 6, which facilitates drainage of the box 1 by removing the corresponding sealing parts 6 to simulate the actual water level of the water-covered slope and improve the accuracy of subsequent tests.

[0046] In one or more embodiments, a plurality of mounting holes 31 are provided on the slope pouring area 3 and the mounting holes 31 are arranged along the length direction of the box body 1. The movable connection between the slope pouring area 3 and the flipping seat 4 is realized through the mounting holes 31.

[0047] Furthermore, the tilting seat 4 includes a connecting plate 43, which has a mating hole 431 corresponding to the size of the mounting hole 31. Both the mounting hole 31 and the mating hole 431 are threaded. Thus, by connecting the mounting hole 31 and the mating hole 431 with bolts, the tilting seat 4 can be connected to the slope pouring area 3. When it is necessary to move the tilting seat 4, the bolts connecting the mounting hole 31 and the mating hole 431 can be released, the tilting seat 4 can be moved to the corresponding position of the mounting hole 31, and then connected again with bolts. Figure 4 . Figure 5 and Figure 6 As shown.

[0048] In one or more embodiments, the flipping seat 4 includes a bearing seat 41, which is fixedly connected to the connecting plate 43, and the side of the bearing seat 41 facing the inside of the slope pouring area 3 is provided with a flipping device 42, which is rotatably connected to the pre-cracked hole forming device 5.

[0049] Furthermore, the body of the flipping device 42 is a ratchet 421 and pawl 422 mechanism, including a ratchet 421, and the flipping device 42 also includes a pawl 422 that cooperates with the ratchet 421;

[0050] Furthermore, the flipping device 42 also includes an outer cover 423, inside which is a mounting base 424. A pawl 422 is rotatably connected to the mounting base 424, and a torsion spring 425 is provided on the pawl 422. One end of the torsion spring 425 is connected to the pawl 422, and the other end is connected to the mounting base 424. When the flipping component 51 is actuated and the ratchet 421 is driven to rotate, the pawl 422 moves from one tooth of the gear to the next until the flipping component 51 is adjusted to the appropriate position. When the flipping component 51 does not need adjustment, 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 to the pawl 422 to prevent displacement of the pawl 422. Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown.

[0051] In one or more embodiments, the pre-cracked hole forming device 5 includes a flipping member 51, and a rotating shaft 511 is provided at one end of the flipping member 51 facing the bearing seat 41. The rotating member 51 is connected to the bearing seat 41 through the rotating shaft 511 to realize the rotation of the flipping member 51.

[0052] Furthermore, the flipping component 51 has several through holes 512 vertically opened, and each through hole 512 is movably connected to a pre-cracked hole mold 52;

[0053] Furthermore, the pre-crack hole mold 52 includes a rod 521 inserted into the through hole 512, and the rod 521 can move along the axial direction of the through hole 512 to adjust the depth of the pre-crack hole. The pre-crack hole mold 52 also includes a pair of limiting nuts 522 threadedly connected to the rod 521. The limiting nuts 522 move in opposite directions on the rod 521 through the threaded connection, thereby clamping the flipping part 51 and further locking the position of the rod 521 to prevent the rod 521 from sliding after it has been adjusted to meet the pre-crack hole depth requirements. Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown.

[0054] In one or more embodiments, the side of the outer cover 423 away from the flipper 51 is connected to the bearing seat 41, and the outer cover 423 is provided with a hole for the rotating shaft 511 to pass through.

[0055] In one or more embodiments, the drain hole 11 is provided with internal threads, and the sealing member 6 is a sealing bolt. The drain hole 11 is sealed by the cooperation between the external threads on the sealing bolt and the internal threads of the drain hole 11.

[0056] Furthermore, a sealing ring is provided on the sealing bolt, which improves the sealing performance after the sealing part 6 is connected to the drain hole 11, preventing water leakage. Figure 1 , Figure 7 and Figure 8 As shown.

[0057] In one or more embodiments, the partition plate 2 and the box body 1 are detachably connected. This can be achieved by snap-fitting or by providing a connection hole on the side of the partition plate 2 facing the side wall of the box body 1, and providing a threaded hole at the corresponding position on the box body 1 that matches the connection hole. After the partition plate 2 is placed inside the box body, the box body 1 and the partition plate 2 are connected as a whole by bolts. When disassembly is required later, only the bolts need to be unscrewed.

[0058] Example 2

[0059] This embodiment 3 is an improvement on the box 1 in embodiment 1.

[0060] The box 1 is provided with a scale, which is coplanar with the mounting hole 31, and the scale is set along the length of the box 1 and is aligned with the outer wall of the box 1.

[0061] Furthermore, the scale is marked with several graduation marks, among which the integer graduations (0, 1, 2...) correspond to the center of the mounting hole 31. Specifically, each integer graduation is aligned with the center of a mounting hole 31 in the vertical direction, so that when the flipping base 4 is moved, the distance moved by the flipping base 4 can be quickly and accurately determined by reading the graduations, which further improves the operating efficiency of the simulation device.

[0062] Alternatively, the ruler can be made of wear-resistant materials, such as alloy steel, and the scale markings on the ruler surface can be laser-engraved to avoid wear or unclear scale markings during use.

[0063] Example 3

[0064] This embodiment 4 is an improvement on embodiment 1.

[0065] The outer cover 423 of the flipping device 42 has an angle mark on the side facing the flipping member 51. The flipping member 51 is provided with a pointer corresponding to the angle mark. In this way, when the flipping member 51 is rotated, the rotation angle of the pre-cracked hole forming device 5 can be clearly seen through the cooperation of the pointer and the angle mark.

[0066] Example 4

[0067] This embodiment 4 is an improvement on the partition plate 2 based on embodiment 1.

[0068] The partition plate 2 can be made of steel plate that matches the shape of the slope to be simulated, according to the actual situation of the slope to be simulated, so as to ensure the consistency between the simulation device and the actual slope to be simulated.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
