Description

Technical Field

[0001] The invention belongs to the field of geological tests, and in particular relates to a test device for fine particle migration law of seepage moraine. Background Art

[0002] Moraines refer to the rocks and debris transported and deposited by glaciers, which are left in place and deposited after the glaciers melt. In mining areas covered with moraines, if natural caving is used for mining, the interior of the strata will be hollowed out, which will inevitably cause surface land subsidence and collapse. Due to its physical properties, during the process of ore discharge or settlement caused by heavy rainfall, coarse particles of moraines are gradually sorted and retained in the soil layer, while fine particles move to the bottom, eventually leading to the formation of underground debris flows.

[0003] In order to study the migration law of fine particles of moraine and prevent underground debris flow, the patent CN217491618U discloses "a screening device for studying surface sediments that form debris flow", which proposes "multi-layer screens with gradually decreasing apertures from top to bottom, used to achieve graded screening of moraine, and assist in studying the content of various particle sizes of surface sediments". Its shortcomings are: 1. It is impossible to conduct rainfall infiltration tests, nor can it divide the soil layer after the natural settlement of moraine into several layers, and it is impossible to identify the proportion of fine particles in different soil layers; 2. It only has a screening function, which can separate moraine with different particle sizes, and cannot infer the settlement law and amplitude from it; 3. It does not have the function of placing markers, and the observation is not intuitive enough.

[0004] A test device with high automation and intuitive simulation effect is proposed. Summary of the invention

[0048] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0049] See also Figures 1 to 3 The present invention provides a test device for fine particle migration law of seepage moraine, the device comprising a test box 101 with an open top surface;

[0050] A stratification unit, which is slidably installed in the test box 101 in a transverse manner and is used to stratify the moraine;

[0051] A screening unit, which is installed on one side outside the test box 101 and is located in the lateral sliding direction of the stratification unit, and is used to screen the moraine in the stratification unit;

[0052] A storage unit is installed above the test box 101 and is used to place test materials.

[0053] The Pulang Copper Mine, located in the Diqing Tibetan Autonomous Prefecture of Yunnan Province, adopts the natural caving mining method. The ore layer is covered with thick moraine. During the mining process, heavy rainfall caused multiple underground mudslides and surface collapse. The preliminary analysis of the mechanism of underground mudslides in the Pulang Copper Mine shows that: after the underground ore body is mined, a goaf is formed, causing the surface to move and collapse, forming a large area of ​​moving area, the upper part of the ore body is covered with moraine, and the surface water and groundwater gradually gather to the bottom of the surface moving area. The moraine is gradually sorted in the process of transferring to the bottom of the surface moving area under the action of surface water transportation, and the coarse particles are retained along the way. The fine particles first reach the bottom of the surface moving area and form a relatively impermeable layer, causing the surface water and part of the underground seepage water to gather in large quantities at the bottom of the surface moving area. Part of the mud-water mixture gathered at the bottom of the pit enters between the collapsed ore fragments under the action of gravity and gradually moves downward with the ore body. The buoyancy of the mud and the shear strength of the slag wrapped in the mud drop sharply to zero. Under the action of gravity, it finally gushes out from the mine outlet to form an underground mudslide.

[0054] In this embodiment, the storage unit stores moraine (or other particles for simulation), markers (colored particles) and water. The storage unit pours the moraine for the test into the test box 101. While putting the moraine in, markers of different colors are spread in layers in the moraine soil layer and then left to stand. After the standing period, the storage unit sprinkles water into the test box 101 to simulate the infiltration process of rainfall. The moraine and markers settle in the test box 101. After the rainfall infiltration is completed, the stratification units are pulled in turn to divide the moraine after natural settlement into several layers and pulled out. The screening unit screens out the markers contained in each layer, observes the particle color, quantity and other data of the markers in this layer, reversely infers the movement law of the markers and fine particles in the natural infiltration process, and observes the movement and deformation law of the top surface at the same time.

[0055] The present invention adds different markers to soil layers at different depths. After infiltration and sedimentation, the soil layers are screened from top to bottom to determine the final positions and quantities of different markers, and the sedimentation amplitude and movement law are reversed. The test results are intuitive, the physical simulation is real and accurate, and it can be fully automated to improve the test efficiency.

[0056] See also Figure 3 A ore storage tank 102 is provided at the bottom of the inner side of the test box 101 , and a plurality of ore discharge funnel openings 103 are provided at the bottom of the ore storage tank 102 .

[0057] In this embodiment, a layer of ore is pre-laid in the ore storage tank 102 to simulate the actual ore layer, and moraine and markers are laid in layers above the ore layer. Simulated rainfall can flow out from the ore discharge funnel mouth 103 to avoid water being trapped in the test box 101. The ore discharge funnel mouth 103 can also simulate the collapse effect of the upper moraine when releasing the ore.

[0058] See also Figures 3 to 6 The two symmetrical inner walls of the test box 101 are provided with a plurality of first chutes 104 from bottom to top, the length direction of the first chutes 104 is parallel to the bottom surface of the test box 101, and the length direction of the first chutes 104 points to the side where the screening unit is located;

[0059] The stratification unit includes a plurality of vertically stacked stratification frames 105, and first sliders 106 are fixedly connected to the symmetrical outer walls of the stratification frames 105. The first sliders 106 are slidably located in the first slide grooves 104. A handle 107 is also installed on the side wall of the stratification frame 105 facing the screening unit.

[0060] In this embodiment, the stratification frames 105 can slide in the direction of the screening unit and can slide relative to each other. A plurality of stratification frames 105 are located above the ore storage tank 102 and are stacked to form a chamber. The moraine and the markers are filled into the chamber formed by the stratification frames 105. When the rainfall infiltration is completed, the moraine and the markers have naturally settled, and the stratification frames 105 are pulled from top to bottom in sequence.

[0061] When a stratification frame 105 is pulled, the stratification frame 105 and the edge of the stratification frame 105 below are sheared, and the moraine in the stratification frame 105 is stratified with the moraine below, and the edge of the screening unit is aligned with the edge of the stratification frame 105 to ensure that the moraine does not fall to the ground during the pulling process. The stratification frame 105 is pulled into the screening unit, driving the layer of moraine into the screening unit for screening.

[0062] See also Figures 3 to 5 The screening unit includes a screening box 201 with an open top surface, the screening box 201 is fixedly connected to and communicated with one side of the test box 101, and the bottom surface of the screening box 201 is provided with a first receiving groove 202 and a second receiving groove 203 in sequence in a direction away from the test box 101, and the first receiving groove 202 and the second receiving groove 203 are provided with a first discharge port 204 and a second discharge port 205 on the side walls;

[0063] The sieving box 201 is provided with a second slide groove 206 and a third slide groove 207 on both symmetrical side walls. The second slide groove 206 and the third slide groove 207 are respectively located on the left and right sides of the sliding direction of the stratified unit. The length direction of the second slide groove 206 and the third slide groove 207 is perpendicular to the bottom surface of the sieving box 201. The second slide groove 206 is rotatably installed with a first threaded rod 208. The third slide groove 207 is fixed with a first slide rod 209. The first threaded rod 208 and the first slide rod 209 are parallel to the length direction of the second slide groove 206.

[0064] The screening unit further includes a screening assembly, which is installed in the second slide groove 206 and the third slide groove 207 in a lifting manner.

[0065] In this embodiment, the first receiving slot 202 is located below the sieve plate 303 and is used to receive the sieved markers, which are collected after falling out of the first discharge port 204. The second receiving slot 203 is used to receive the moraine remaining after sieving, which is taken out from the second discharge port 205.

[0066] The screening assembly is installed in the second slide groove 206 and the third slide groove 207, and the first threaded rod 208 drives the screening assembly to rise and fall.

[0067] See also Figures 7 and 8 The screening assembly includes a first side plate 301, a second side plate 302, a screen plate 303, a screen hole 304, a second slider 305, a third slider 306, a fifth slide 307, a sixth slide 308, a second threaded rod 309, a second slide rod 310, a connecting block 311 and a clamp 312;

[0068] The length direction of the first side plate 301 and the second side plate 302 is parallel to the sliding direction of the stratified unit, and the first side plate 301 and the second side plate 302 are respectively located on the left and right sides of the sliding direction of the stratified unit, and the first side plate 301 and the second side plate 302 are respectively located on the left and right sides of the sliding direction of the stratified unit, and the first side plate 301 is fixedly connected to the second sliding groove 206 on the side of the first side plate 301, and the second sliding groove 206 is slidably located in the second sliding groove 206 and is threadedly connected with the first threaded rod 208, and the second side plate 302 is fixedly connected to the third sliding groove 207 on the side of the second side plate 302, and the third sliding groove 306 is slidably located in the third sliding groove 207 and is slidably sleeved on the first sliding rod 209, and the sieve plate 303 is erected between the first side plate 301 and the second side plate 302, and is fixedly connected to the first side plate 301 and the second side plate 302, and a plurality of sieve holes 304 are opened on the sieve plate 303, and the length of the sieve plate 303 is half of the length of the fifth sliding groove 307, and the sieve plate 303 is located above the first receiving groove 202;

[0069] A fifth slide groove 307 and a sixth slide groove 308 are respectively provided on the opposite sides of the first side plate 301 and the second side plate 302, and the length directions of the fifth slide groove 307 and the sixth slide groove 308 are parallel to the sliding direction of the stratified unit. A second threaded rod 309 is rotatably installed in the fifth slide groove 307, and a second slide rod 310 is fixedly connected in the sixth slide groove 308. The second threaded rod 309 and the second slide rod 310 are both parallel to the fifth slide groove 307. One end of the connecting block 311 extends into the fifth slide groove 307 and is threadedly connected to the second threaded rod 309. The other end of the connecting block 311 extends into the sixth slide groove 308 and is slidably mounted on the second slide rod 310. A clamp 312 is installed on the side of the connecting block 311 facing the stratified unit.

[0070] In this embodiment, the first threaded rod 208 drives the first side plate 301 to move up and down, thereby driving the sieve plate 303 to move up and down, and the sieve plate 303 moves up and down to the corresponding height of the stratification frame 105, and the edge of the sieve plate 303 fits with the edge of the stratification frame 105;

[0071] The second threaded rod 309 cooperates with the second sliding rod 310 to drive the connecting block 311 to move. When the connecting block 311 approaches the stratification frame 105, the clamping hand 312 clamps the handle 107 of the stratification frame 105. Then, when the connecting block 311 retreats, the clamping hand 312 pulls the stratification frame 105 onto the screen plate 303. The edge of the screen plate 303 is aligned with the edge of the stratification frame 105 to prevent moraine from falling out when pulling.

[0072] After the stratification frame 105 is located on the sieve plate 303, the connecting block 311 starts to reciprocate slightly, and the clamping hand 312 drives the stratification frame 105 to shake back and forth. During the shaking process, the marker is screened out from the moraine, and the marker falls from the sieve plate 303 and falls into the first receiving groove 202 below. After the screening is completed, the connecting block 311 continues to pull the stratification frame 105 backwards.

[0073] Because the length of the sieve plate 303 is half the length of the fifth slide groove 307, the connecting block 311 continues to move backward in the fifth slide groove 307, and the stratification frame 105 will move to the edge of the sieve plate 303. At this time, the stratification frame 105 is located above the second receiving groove 203. Because the stratification frame 105 is hollowed out above and below, the remaining moraine in the stratification frame 105 falls into the second receiving groove 203 below.

[0074] See also Figures 7 and 8 A fourth sliding groove 313 for the first slider 106 to slide is respectively opened on the opposite side of the first side plate 301 and the second side plate 302 , and the length direction of the fourth sliding groove 313 is parallel to the first sliding groove 104 .

[0075] In this embodiment, when the sieve plate 303 is raised or lowered to the corresponding height of the stratification frame 105, the clamp 312 pulls the stratification frame 105 onto the sieve plate 303, and the first slider 106 of the stratification frame 105 slides from the first slide groove 104 into the fourth slide groove 313. When the stratification frame 105 continues to move backward to the edge of the sieve plate 303, the fourth slide groove 313 can also support the stratification frame 105 to prevent the stratification frame 105 from falling into the second receiving groove 203.

[0076] See also Figures 4 to 5A lifting groove 210 is provided on the top surface of the side wall between the first receiving groove 202 and the second receiving groove 203, and a lifting plate 211 is slidably installed in the lifting groove 210. The top surface of the lifting plate 211 contacts the bottom surface of the sieve plate 303. A spring 212 is installed in the lifting groove 210. The compression direction of the spring 212 is perpendicular to the ground. One end of the spring 212 is fixedly connected to the bottom of the lifting groove 210, and the other end is fixedly connected to the bottom surface of the lifting plate 211.

[0077] In this embodiment, in the initial state, the lifting plate 211 is lifted by the spring 212, and the lifting plate 211 is located below the sieve plate 303. The lifting plate 211 separates the first receiving groove 202 and the second receiving groove 203 to prevent the marker from falling into the second receiving groove 203 and to prevent glacial materials from falling into the first receiving groove 202. When the sieve plate 303 gradually descends and aligns with the lower layer frame 105, the sieve plate 303 presses the lifting plate 211 into the lifting groove 210, and the spring 212 is compressed.

[0078] See also Figure 1 , Figure 2 , Fig. 9 and Fig.10 The storage unit includes a slide rail 401, which is fixed to the top of the test box 101 and the screening box 201 and is arranged along the sliding direction of the stratified unit. A sliding plate 402 is slidably mounted on the slide rail 401. The sliding plate 402 is located above the test box 101 and the screening box 201. A material storage barrel 403 and a liquid storage barrel 404 are fixed to the sliding plate 402.

[0079] The bottom surface of the material storage barrel 403 is fixedly connected with a discharge pipe 405, the other end of the discharge pipe 405 faces the test box 101, and a solenoid valve 406 is installed on the discharge pipe 405;

[0080] A plurality of nozzles 407 are fixedly connected to the bottom surface of the liquid storage barrel 404 , and the other ends of the nozzles 407 face the test box 101 .

[0081] In this embodiment, the bottom surface of the sliding plate 402 is installed with power, which can slide on the slide rail 401, driving the storage barrel 403 to move to the top of the test box 101 to release moraine materials, wherein it periodically switches to the marker spreading plate 408 to release markers in layers in the moraine soil layer. After the release is completed, it drives the liquid storage barrel 404 to move to the top of the test box 101 to simulate rainfall and fill the test box 101 with water.

[0082] See also Figure 10 to Figure 11The storage unit further includes a marker spreading disc 408, which is rotatably mounted on the sliding plate 402, and a plurality of fan-shaped grids 409 are evenly arranged on the top surface of the marker spreading disc 408 around the center of the circle, and leakage holes 410 are arranged at the bottom of the fan-shaped grids 409, and a baffle 411 is rotatably mounted on the bottom surface of the marker spreading disc 408, and the baffle 411 is coaxial with the marker spreading disc 408, and a second leakage hole 412 cooperating with any leakage hole 410 is arranged on the baffle 411;

[0083] A first gear ring 413 is fixedly connected to the circumferential outer wall of the marker spreading plate 408, a second gear ring 414 is fixedly connected to the circumferential outer wall of the baffle plate 411, and a first power source 415 and a second power source 416 are also installed on the sliding plate 402. A first gear 417 is fixedly connected to the output shaft of the first power source 415, and the first gear 417 is meshed with the first gear ring 413. A second gear 418 is fixedly connected to the output shaft of the second power source 416, and the second gear 418 is meshed with the second gear ring 414.

[0084] In this embodiment, after a certain amount of moraine material is put into the storage barrel 403, the sliding plate 402 slides, and the marker spreading plate 408 is aligned with the test box 101 to put the marker, and then the sliding plate 402 slides, switches back to the storage barrel 403, covers the marker with new moraine material, and then switches the marker spreading plate 408, and so on and so forth, forming a moraine soil layer with multiple layers of markers;

[0085] Different colored particles are stored in different sector-shaped grids 409. The particles may be quartz sand of different colors or colored ground glass beads. Under normal conditions, the baffle plate 411 blocks the leakage hole 410. When the second leakage hole 412 is aligned with any leakage hole 410, and the marker spreading plate 408 rotates synchronously with the baffle plate 411, the markers in the sector-shaped grid 409 at that location continuously fall out and are evenly spread in the test box 101 following the rotation of the marker spreading plate 408.

[0086] When the baffle 411 rotates and the marker spreading plate 408 does not rotate, the second leakage hole 412 is aligned with different leakage holes 410 in sequence, and markers in different sector grids 409 can be dropped out to form a specific combination marker.

[0087] See also Figure 10 to Figure 1 An image acquisition element is also provided outside the test box 101.

[0088] In this embodiment, an image acquisition element (not shown in the figure) can be provided outside the test box 101. The image acquisition element is usually a camera device for aiming at the ore-drawing funnel mouth 103 to capture the water flow rate flowing out during rainfall simulation.

[0089] Complete workflow: The storage unit first pours the test moraine material into the test box 101 from the storage bucket 403, then slides the sliding plate 402, aligns the marker spreading plate 408 with the test box 101 to drop the marker, and repeats this process to form a moraine soil layer with multiple layers of markers;

[0090] Then, it is left to stand for a period of time. After the standing period is over, the storage unit aligns the liquid storage barrel 404 with the test box 101 to sprinkle water, simulating the infiltration process of rainfall. The moraine and the markers settle in the test box 101. After the rainfall infiltration is over, the sieve plate 303 rises to the position of the uppermost stratification frame 105, and the clamping hand 312 pulls the stratification frame 105 to the sieve plate 303. The stratification frame 105 moves horizontally onto the sieve plate 303 with the moraine inside. Then, the clamping hand 312 reciprocates to drive the stratification frame 105 to shake, and the marker is screened out from the moraine. The marker passes through the sieve plate 303 and falls off, and the moraine remains in the stratification frame 105. Then, the clamping hand 312 continues to pull the stratification frame 105 backwards, and the stratification frame 105 moves to the edge of the sieve plate 303. The stratification frame 105 is hollowed out from top to bottom, and the moraine falls off. Finally, the clamping hand 312 pushes the stratification frame 105 back into the test box 101.

[0091] The sieve plate 303 descends, pulling the new stratification frame 105 below, and the stratification frame 105 is pulled out from top to bottom in sequence to sieve out the markers in each layer of moraine. The markers fall out of the sieving box 201, and the staff counts the number, color and other data of the markers, and reversely infers the movement patterns of the markers and fine particles in the natural infiltration process, while observing the movement and deformation patterns of the top surface.
