[0002] In the field of geotechnical engineering, geotechnical seepage experiment is a key link in evaluating the seepage performance of geotechnical materials, understanding the law of groundwater flow and conducting geological engineering design. Traditional geotechnical seepage experiment devices usually use fixed compaction mechanisms to compact geotechnical samples manually or with simple mechanical devices to simulate the compaction state of geotechnical samples under actual geological conditions.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: a rock and soil seepage experimental device, comprising a test bench 1, a material storage box 2 is arranged on the test bench 1, a pressing plate 3 is arranged above the material storage box 2, and a compacting component 4 is arranged on one side of the pressing plate 3;

[0030] The surface of the test bench 1 is provided with a transverse groove 11 and a vertical groove 12, and the vertical groove 12 is connected to the transverse groove 11 to facilitate the movement and positioning of the components;

[0031] The compaction assembly 4 includes a movable plate 41 which is laterally slidably mounted on the test bench 1. An inclined groove 42 is provided on the surface of the movable plate 41. An adjusting rod 43 is slidably connected in the inclined groove 42. A fixed block 45 is fixedly connected to the front end of the adjusting rod 43. A rectangular block 46 is slidably connected to the fixed block 45. A compaction plate 49 for compacting the rock and soil to be tested is fixedly connected to the bottom of the rectangular block 46. A slider 44 is fixedly connected to the rear end of the adjusting rod 43. The slider 44 is slidably mounted in the horizontal groove 11 and the vertical groove 12. An adjusting motor 47 is fixedly connected to the top of the fixed block 45. A threaded rod 48 is fixedly connected to the output end of the adjusting motor 47. The threaded rod 48 is threadedly connected to the rectangular block 46. By rotating the adjusting motor 47, the movement of the threaded rod 48 can be accurately controlled, and then the position of the rectangular block 46 can be adjusted to achieve fine control of the compaction plate 49. One end of the movable plate 41 rotates It is connected with a connecting rod 410, and the other end of the connecting rod 410 is rotatably connected with a rotating rod 411. The other end of the rotating rod 411 is provided with a driving motor 412 fixedly installed on the test bench 1. By turning on the driving motor 412, the rotating rod 411 is driven to rotate synchronously, and the rotating rod 411 drives the connecting rod 410 to move back and forth, so that the connecting rod 410 drives the moving plate 41 to move back and forth, so that the moving plate 41 drives the slider 44 to slide in the horizontal groove 11 and the vertical groove 12, and so on and so forth, driving the compacting plate 49 to move back and forth. When the moving plate 41 moves to one side of the storage box 2, under the action of the inclined groove 42, the slider 44 moves from the horizontal groove 11 to the vertical groove 12, thereby being able to drive the slider 44, the moving plate 41, the fixed block 45, the rectangular block 46, and the compacting plate 49 to move downward, so that the compacting plate 49 compacts the rock and soil to be tested in the storage box 2;

[0032] The two sides of the bottom of the fixed block 45 are connected with cross bars 413 for transverse sliding, and the outer ends of the cross bars 413 are fixedly connected with connecting plates 414. The slider 44 is rotatably connected with a sleeve rod 415, and the outer ends of the sleeve rod 415 are fixedly connected with a cam 416. The bottom of the cam 416 is provided with a knocking rod 417 slidably installed on the connecting plate 414 in the vertical direction. The surface of the knocking rod 417 is fixedly connected with a limit block 418, and a damping spring 419 sleeved on the knocking rod 417 is provided between the limit block 418 and the connecting plate 414. The limit block 418 and the knocking rod 417 are pushed upward under the elastic force of the damping spring 419, so that the top of the knocking rod 417 slides in contact with the outer wall of the cam 416. When the sleeve rod 415 rotates, it drives the cam 416 to rotate synchronously. When the cam 416 rotates, it pushes the knocking rod 417 to move up and down under the elastic force of the damping spring 419, so that the knocking rod 417 knocks the top of the compacting plate 49 back and forth. The reciprocating knocking of the knocking rod 417 on the top of the compacting plate 49 can further The compaction effect of rock and soil is further enhanced. This dynamic compaction method helps to further reduce the gaps between rock and soil particles, improve the compactness and uniformity of rock and soil, and thus more accurately simulate the rock and soil characteristics under actual geological conditions. The knocking treatment helps to improve the internal structure of rock and soil and make it more stable. By knocking, rock and soil particles can be rearranged to form a tighter combination, thereby improving the shear strength and compressibility of rock and soil. The reciprocating knocking of the knocking rod 417 can disperse these stresses and reduce the damage to the rock and soil structure caused by stress concentration, which helps to maintain the integrity of the rock and soil and improve its performance in experiments or applications. The reciprocating knocking treatment of the compaction plate 49 by the knocking rod 417 can ensure that the rock and soil samples have a more consistent compaction and density during the experiment, which helps to reduce experimental errors and improve the reliability and accuracy of experimental data, thereby more accurately evaluating the seepage performance and other related characteristics of rock and soil, making the experimental results closer to the performance of rock and soil in actual applications, and providing a more scientific basis for the design and construction of geotechnical engineering.

[0033] The two sleeve rods 415 are connected together by lateral sliding, and they are connected by a spline rod 420. The spline rod 420 is designed to be rotatable and installed inside the fixed block 45. In order to ensure the stability and functionality of the structure, a first bevel gear 421 is fixedly connected to the spline rod 420. In addition, the two connecting plates 414 are connected to a reciprocating screw rod 428 by threaded connection. The reciprocating screw rod 428 is also designed to be rotatable and installed inside the fixed block 45. In order to achieve reciprocating motion, the reciprocating screw rod A second bevel gear 422 is fixedly connected to the fixed block 45. A connecting shaft 423 is also designed to be rotatably connected inside the fixed block 45. The two ends of the connecting shaft 423 are respectively fixedly connected to a third bevel gear 424 and a fourth bevel gear 425. In order to achieve meshing transmission between the gears, the third bevel gear 424 is meshed with the first bevel gear 421, and the fourth bevel gear 425 is meshed with the second bevel gear 422. In order to provide power, a servo motor 426 is also fixedly installed inside the fixed block 45. The output end of the servo motor 426 is fixedly connected to the There is a fifth bevel gear 427 meshing with the second bevel gear 422. When the servo motor 426 is turned on, it will drive the fifth bevel gear 427 to rotate synchronously. The rotation of the fifth bevel gear 427 will further drive the meshing second bevel gear 422 to rotate. The rotation of the second bevel gear 422 will drive the reciprocating screw rod 428 to rotate synchronously, so that the reciprocating screw rod 428 cooperates with the cross bar 413 to drive the connecting plate 414 to reciprocate. The reciprocating movement of the connecting plate 414 will synchronously drive the sleeve rod 415 to reciprocate, thereby driving the cam 416 and the knocking rod 416. 7 synchronously reciprocates, so that the knocking rod 417 can knock different positions of the compacting plate 49. At the same time, the rotating second bevel gear 422 will also drive the meshing fourth bevel gear 425 and the connecting shaft 423 and the third bevel gear 424 to rotate. The rotation of the third bevel gear 424 will drive the meshing first bevel gear 421 to rotate, and the rotation of the first bevel gear 421 will drive the spline rod 420 to rotate synchronously. The rotation of the spline rod 420 will drive the sleeve rod 415 and the cam 416 to rotate synchronously, thereby realizing the coordinated operation of the entire mechanical device.

[0034] In an embodiment of the present invention, the threaded rod 48 is driven to rotate synchronously by turning on the adjustment motor 47, and the threaded rod 48 drives the rectangular block 46 and the compaction plate 49 to move up and down, thereby adjusting the initial height of the compaction plate 49 and the storage box 2, thereby changing the compaction strength of the compaction plate 49 on the rock and soil in the storage box 2. By accurately adjusting the initial height of the compaction plate 49 and the storage box 2, it can be ensured that the compaction plate 49 acts on the rock and soil with appropriate force during the descent process, avoiding excessive or insufficient compaction, and different rock and soil types and humidity may require different compaction strengths. By adjusting the initial height, personalized compaction treatment can be performed for rocks and soils of different properties to achieve the best compaction effect. By starting the drive motor 412, the rotating rod 411 is driven to perform synchronous rotational movement. The rotation of the rotating rod 411 will prompt the connecting rod 410 to perform reciprocating linear movement, and this action will cause the moving plate 41 to perform reciprocating linear movement. The movement of the moving plate 41 drives the slider 44 to slide smoothly in the horizontal groove 11 and the vertical groove 12. This reciprocating motion mechanism enables the compaction plate 49 to move back and forth. When the moving plate 41 moves toward the storage box 2, the inclined groove 42 enables the slider 44 to smoothly transition from the position of the horizontal groove 11 to the vertical groove 12. This process can effectively drive the slider 44 and the moving plate 41. The fixed block 45, the rectangular block 46 and the compaction plate 49 move downward as a whole. Through this downward movement, the compaction plate 49 can apply pressure to the rock and soil to be tested in the storage box 2 to perform compaction. The purpose of the compaction is to ensure that the density and compactness of the rock and soil to be tested remain consistent during the experiment, which can significantly reduce the experimental error caused by loose rock and soil or uneven density. In this way, the experiment can more accurately simulate the actual geological conditions, thereby improving the reliability and accuracy of the experimental data. In addition, the compaction process can also reduce the gaps between rock and soil particles and improve the uniformity of the rock and soil. When conducting a seepage experiment, a uniform rock and soil sample can more realistically reflect the permeability characteristics of water flow in the soil, which helps to more accurately evaluate the seepage performance of the rock and soil;

[0035] By activating the servo motor 426, the synchronous rotation of the fifth bevel gear 427 can be achieved. The rotation of the fifth bevel gear 427 will drive the second bevel gear 422 meshing therewith to rotate. The rotation of the second bevel gear 422 will prompt the reciprocating screw rod 428 to rotate synchronously. The reciprocating screw rod 428 cooperates with the cross bar 413 to drive the connecting plate 414 to move back and forth in a straight line. At the same time, the movement of the connecting plate 414 will cause the sleeve rod 415 to move back and forth synchronously. The movement of the sleeve rod 415 will drive the cam 416 and the knocking rod 417 to move back and forth synchronously, so that the knocking rod 417 can knock on different positions of the compacting plate 49. At the same time, the rotating second bevel gear Wheel 422 will also drive the fourth bevel gear 425 meshing with it, as well as the connecting shaft 423 and the third bevel gear 424 to rotate. The rotation of the third bevel gear 424 will further drive the rotation of the first bevel gear 421, and the rotation of the first bevel gear 421 will cause the spline rod 420 to rotate synchronously. The rotation of the spline rod 420 drives the sleeve rod 415 and the cam 416 to rotate synchronously. During the rotation, the cam 416 cooperates with the elastic force of the damping spring 419 to push the knocking rod 417 to move up and down. The reciprocating knocking treatment of the knocking rod 417 on the top of the compaction plate 49 can further enhance the compaction effect of the rock and soil, and ensure that the pressure applied by the compaction plate 49 to the rock and soil is more uniform and effective.

A push rod 37 is slidably connected to the inner wall of the second through hole 36, and two ends of the push rod 37 are respectively fixedly connected to the water injection block 32 and the exhaust block 34.

[0039] In the embodiment of the present invention, the cylinder 38 is turned on to drive the pressure plate 3 to move downward, so that after the pressure plate 3 is docked with the storage box 2, water is discharged into the storage box 2 through the water injection hole 31. After the water flows into the water injection hole 31 through the water injection pipe, the extrusion angle on one side of the water injection stopper 32 is squeezed by the water pressure, and the water injection stopper 32 is pushed into the storage chute on the inner wall of the water injection hole 31 through the extrusion angle. While the water injection stopper 32 moves, the exhaust stopper 34 is driven by the push rod 37 to move to the storage chute on the inner wall of the exhaust hole 33. At this time, the exhaust hole 33 is opened, and the air inside the storage box 2 can be discharged through the exhaust hole 33. When the water injection is completed, the water injection hole 31 is closed. When the internal water pressure disappears, the exhaust block 34 is reset under the elastic force of the reset spring 35, and the exhaust hole 33 is blocked again. The water injection block 32 is driven to reset and block the water injection hole 31 through the push rod 37. Then the inside of the storage box 2 can be pressurized through the pressure plate 3, which is convenient for adjusting the pressure during seepage. The seepage pressure can exceed the natural gravity of the water inside the device, which is convenient for adapting to different usage needs during the test. It has good adaptability and is provided with a water injection hole 31 and an exhaust hole 33. The opening and closing of the water injection hole 31 and the exhaust hole 33 are controlled by the push rod 37 and the reset spring 35. The opening and closing of the exhaust hole 33 can be automatically controlled according to the start and stop of the water injection operation, which is convenient to use.

When the moving plate 41 moves to one side of the storage box 2, under the action of the inclined groove 42, the slider 44 moves from the horizontal groove 11 to the vertical groove 12, thereby being able to drive the slider 44, the moving plate 41, the fixed block 45, the rectangular block 46, and the compacting plate 49 to move downward, so that the compacting plate 49 compacts the rock and soil to be tested in the storage box 2;

[0044] Step 2: Turn on the servo motor 426 to drive the fifth bevel gear 427 to rotate synchronously, the fifth bevel gear 427 drives the meshed second bevel gear 422 to rotate, and the second bevel gear 422 drives the reciprocating screw 428 to rotate synchronously, so that the reciprocating screw 428 cooperates with the cross bar 413 to drive the connecting plate 414 to reciprocate, and the connecting plate 414 drives the sleeve rod 415 to reciprocate synchronously, thereby driving the cam 416 and the knocking rod 417 to reciprocate synchronously, so that the knocking rod 417 knocks on different positions of the compacting plate 49;

[0045] Step 3: After the compaction work of the compaction plate 49 is completed, the cylinder 38 is turned on to drive the pressing plate 3 to move downward, so that after the pressing plate 3 is docked with the storage box 2, water is discharged into the storage box 2 through the water injection hole 31. After the water flows into the water injection hole 31 through the water injection pipe, the extrusion angle on one side of the water injection stopper 32 is squeezed by the water pressure, and the water injection stopper 32 is pushed into the storage chute on one side of the inner wall of the water injection hole 31 through the extrusion angle. When the water injection stopper 32 moves, the exhaust stopper 34 is driven by the push rod 37 to move to the storage chute on one side of the inner wall of the exhaust hole 33 The exhaust hole 33 is opened at this time, and the air inside the storage box 2 can be discharged through the exhaust hole 33. When the water injection is completed, the water pressure inside the water injection hole 31 disappears, and the exhaust block 34 is reset under the elastic force of the reset spring 35, and the exhaust hole 33 is blocked again, and the water injection block 32 is driven by the top rod 37 to reset and block the water injection hole 31. Then, the inside of the storage box 2 can be pressurized by the pressing plate 3, which is convenient for adjusting the pressure during seepage, and the seepage pressure can be made to exceed the natural gravity of the water inside the device, which is convenient for adapting to different usage needs during the test;

[0046] Step 4, when the pressing plate 3 is working under pressure, the rotating baffle 26 can be driven to rotate by rotating the handle 25, and the first through hole 28 on the rotating baffle 26 can be rotated to the side facing the sealing plate 27, and the first through hole 28 on the rotating baffle 26 can be blocked by the sealing plate 27, so that the storage box 2 can be sealed from the outside, so that when the pressing plate 3 is pressurized, the water inside the storage box 2 will not overflow. When natural pressure is needed, that is, the pressing plate 3 is not working, the rotating baffle 26 can be driven to rotate by rotating the handle 25, and the first through hole 28 on the rotating baffle 26 is exposed, and the water inside the storage box 2 can overflow, which can freely adapt to the test needs of pressurized seepage and natural pressure seepage.
