Description

Technical Field

[0001] This invention belongs to the field of foundation filling, specifically an auxiliary device for vibratory compaction of stone piles and its operating method. Background Technology

[0002] Vibro-compacted stone piles refer to the construction process of creating numerous stone piles in the foundation using vibratory water jetting. These piles, together with the original foundation soil, form a composite foundation to improve the bearing capacity of the foundation. By replacing the original foundation soil with stone piles, the stone aggregate acts as reinforcement within the original soil. Because the piles are more rigid than the surrounding soil, the foundation stress is concentrated on the stone piles, reducing the additional stress on the surrounding soil and thus increasing the overall bearing capacity of the composite foundation while reducing compressibility.

[0003] After drilling holes in the foundation using a vibratory compactor, crushed stone needs to be poured into the holes to form crushed stone piles. However, the bottom of the vibratory compactor is mostly designed with a conical surface for drilling. When the crushed stone is compressed, the inclined surface at the bottom of the vibratory compactor pushes the crushed stone below to the side, intruding into the soil inside the hole. The pressure on the soil below can easily lead to a collapse above the pressure point. Furthermore, when the crushed stone is compressed by the vibratory compactor, it can damage parts on the vibratory compactor, such as water nozzles. Secondly, when the crushed stone enters the hole along the outer edge of the vibratory compactor, it is impossible to control the crushing process. If too much gravel is put into the hole at once, there will be too many voids inside, which cannot be filled by vibration. This can lead to broken piles. In addition, in order for the gravel to enter the hole, the size of the vibratory compactor needs to be smaller than the hole diameter. However, the hole wall excavated by water is not effectively compacted, resulting in loose soil inside the hole. When the gravel is poured, the soil inside the hole wall is prone to collapse due to the continuous collision of the gravel as it falls, and it mixes into the gravel pile, affecting the quality of the gravel pile.

[0004] Therefore, the present invention provides an auxiliary device for vibratory compaction of stone piles and its operating method. Summary of the Invention

[0005] To address the shortcomings of existing technology, the bottom of vibratory compactors, which are mostly designed with a conical surface for drilling, is often designed to be conical. When compacting gravel, the inclined surface at the bottom of the vibratory compactor pushes the gravel below to the side, intruding into the soil inside the hole. The pressure on the soil below can easily lead to landslides above. Furthermore, the gravel compaction process can damage components of the vibratory compactor, such as water nozzles. Additionally, the amount of gravel entering the hole along the outer edge of the vibratory compactor is uncontrollable; if too much gravel enters the hole at once, it can cause internal damage. There are many gaps that are difficult to fill by vibration, which can lead to broken piles. In addition, in order for the crushed stone to enter the hole, the size of the vibratory compactor needs to be smaller than the hole diameter. However, the hole wall excavated by water is not effectively compacted, resulting in loose soil inside the hole. When the crushed stone is poured, the soil inside the hole wall is prone to collapse due to the continuous collision of the crushed stone during the fall, and mixes into the crushed stone pile, affecting the quality of the crushed stone pile.

One end of the first spring is fixedly connected to the mounting plate, and the other end of the first spring is fixedly connected to the top plate. A linkage unit is provided on one side of the mounting plate.

[0010] Preferably, the linkage unit includes a second sliding shaft, which is fixedly installed on one side of the mounting plate. One end of the second sliding shaft extends into the interior of the discharge chute and is fixedly connected to a top block. The top of the top block is set as an inclined surface.

[0015] A method for operating an auxiliary device for forming vibratory crushed stone piles, applicable to the aforementioned auxiliary device, comprises the following steps:

[0016] S1: Move the sleeve above the foundation vibratory borehole by controlling the vehicle body, start the first motor, and control the sleeve to move downward and enter the vibratory borehole;

[0017] S2: Put the crushed stone into the first feed trough, start the second motor, and control the extrusion head to move up and down repeatedly, so that the crushed stone enters the vibratory punch hole in small amounts and multiple times.

[0018] S3: Start the third motor to control the sleeve to rotate back and forth, which in turn drives the top plate to rotate back and forth. This, in conjunction with the top plate's pressure on the hole wall, compacts the hole wall while smoothing it out.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The auxiliary device and its operation method for vibratory compaction of crushed stone piles of the present invention, wherein the sleeve is controlled by a first motor to intermittently compress downwards, and in conjunction with the bottom of the partition plate, the crushed stone entering the vibratory compaction hole is compacted. The crushed stone entering the vibratory compaction hole is wrapped by the set compression ring. As the sleeve moves downwards, in conjunction with the concave surface formed by the discharge chute and the partition plate, the crushed stone can be concentrated inwards and piled up upwards in a pagoda shape, so as to avoid excessive compression of the hole wall of the vibratory compaction hole and cause the hole wall to collapse.

[0021] 2. The auxiliary device and its operating method for forming vibratory crushed stone piles according to the present invention, by blocking the partition, the crushed stone is kept above the partition. The extrusion head is controlled by a second motor to move up and down reciprocally. When the extrusion head moves down, it pushes the two partitions to rotate down at the same time. The crushed stone in the discharge chute passes through the two partitions and falls into the vibratory hole for filling. At the same time as the extrusion head moves down, it blocks the second feed chute, stopping the feeding of the second feed chute. This process is repeated. With the reciprocating up and down movement of the extrusion head, the crushed stone can enter the vibratory hole in small amounts and multiple times, avoiding the appearance of a large number of gaps inside due to too much crushed stone entering at one time, which would affect the quality of the crushed stone pile. As the crushed stone is continuously filled...

[0022] 3. The auxiliary device and its operation method for forming vibratory crushed stone piles according to the present invention, through the cooperation of the extrusion head and the top block, when the extrusion head moves downward, pushes several mounting plates to move outward simultaneously, and drives several top plates to move outward simultaneously, compacting the hole wall of the vibratory crushing hole, avoiding collapse due to the unstable hole wall structure. When encountering the solidified hole wall, the top plate is retracted by the first spring, avoiding excessive compression of the solidified hole wall.

[0023] 4. The auxiliary device and its operation method for vibratory compaction of stone piles described in this invention control the sleeve to reciprocate in both directions via a third motor, which in turn drives the top plate to reciprocate in both directions. As the top plate compresses and rotates against the hole wall, it smooths the compacted hole wall, improving the smoothness of the hole wall surface and preventing soil from falling into the stone pile during filling. By setting the outer wall of the top plate to an arc shape, it is easier to improve the smoothing effect on the hole wall and reduce damage to the hole wall.

[0024] 5. The auxiliary device and its operation method for vibratory compaction of stone piles of the present invention involves placing crushed stone near the first rotating shaft, guiding the placed crushed stone through a set guide ring, causing the crushed stone to concentrate towards the top of the sleeve, and through the wrapping of the collecting ring, allowing the crushed stone to fall accurately into the first feeding trough, thereby preventing the crushed stone from sliding directly along the outer edge of the sleeve and colliding with the hole wall of the vibratory compaction hole, which would cause the soil on the hole wall to landslide.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 11As shown, the present invention provides a technical solution: an auxiliary device for vibratory compaction of stone piles, comprising a vehicle body 1, a fixed frame 2 fixedly connected to one side of the vehicle body 1, a first motor 3 fixedly connected to the bottom of the fixed frame 2, the output end of the first motor 3 extending into the interior of the fixed frame 2 and fixedly connected to a lead screw 4, the lead screw 4 being rotatably connected to the fixed frame 2, a connecting block 5 connected to the outer wall of the lead screw 4 via a lead screw nut pair, the connecting block 5 being slidably connected to the fixed frame 2, a support plate 6 fixedly connected to one side of the connecting block 5, a first rotating shaft 7 rotatably connected to the inner wall of the support plate 6, a sleeve 8 fixedly connected to the bottom of the first rotating shaft 7, a sleeve 9 fixedly connected to the bottom of the sleeve 8, a first feeding groove 10 opened at the top of the sleeve 9, a second feeding groove 11 opened inside the sleeve 9, the bottom of the second feeding groove 11 being configured as an annular inclined surface, the first feeding groove 10 communicating with the second feeding groove 11, and a discharge groove 12 opened at the bottom of the sleeve 9, the discharge groove 12 being connected to the second feeding groove 11 is connected, and a material blocking assembly is provided inside the sleeve 9; the material blocking assembly includes two mounting grooves 41, which are symmetrically opened inside the sleeve 9. A second rotating shaft 39 is fixedly connected inside each of the two mounting grooves 41. A partition plate 40 is rotatably connected to the outer wall of each of the two second rotating shafts 39. The partition plate 40 is installed at an angle and one side extends into the interior of the discharge chute 12. A spring plate 38 is fixedly connected between the partition plate 40 and the mounting groove 41. A second motor 13 is fixedly connected to the top of the sleeve 9 and inside the sleeve box 8. The output end of the second motor 13 extends into the interior of the sleeve 9 and is fixedly connected to a reciprocating screw 14. A slider 15 is provided on the reciprocating screw 14, and the protrusion of the slider 15 is embedded in the closed thread groove of the reciprocating screw 14. The reciprocating screw 14 rotates to drive the slider 15 to reciprocate. A ring frame 16 is fixedly connected to the bottom of the slider 15. An extrusion head 17 is fixedly connected to the bottom of the ring frame 16. The extrusion head 17 is slidably connected to the sleeve 9.

[0040] Through the above technical solution, the sleeve 9 is moved above the foundation vibratory punching hole by the vehicle body 1, the first motor 3 is started, driving the lead screw 4 to rotate, causing the connecting block 5 to move downward, driving the support plate 6 to move downward, causing the first rotating shaft 7 to move downward, driving the sleeve 9 to move downward and enter the vibratory punching hole. Through the two spring plates 38, the two partitions 40 block the discharge chute 12, and the crushed stone is put into the first feed chute 10. The crushed stone enters the second feed chute 11 along the first feed chute 10 and slides down the inclined surface at the bottom of the second feed chute 11 into the discharge chute 12. Through the obstruction of the partitions 40, the crushed stone stays above the partitions 40. The second motor 13 is started, driving the reciprocating lead screw 14 to rotate, causing the slider 15 to move up and down reciprocally, driving the ring frame 16 to move up and down reciprocally, and causing the extrusion head 17 to move up and down reciprocally. When the extrusion head 17 moves downward, it pushes the crushed stone in the discharge chute 12 downward. Under the pressure of the extrusion head 17, the two partitions 40 rotate downwards simultaneously, pressing the two spring plates 38. When the two partitions 40 move downwards, they lose their obstruction to the discharge chute 12. The crushed stone in the discharge chute 12 passes through the two partitions 40 and falls into the vibratory hole for filling. At the same time, the extrusion head 17 moves downwards and blocks the second feed chute 11, stopping the feeding of the second feed chute 11. After the extrusion head 17 moves upwards, the second feed chute 11 can continue to feed. At the same time, the spring plates 38 rebound, causing the partitions 40 to block the discharge chute 12 again. This process is repeated. As the extrusion head 17 moves up and down, the crushed stone can enter the vibratory hole in small amounts multiple times, avoiding the formation of a large number of gaps inside due to too much crushed stone entering at once, which would affect the quality of the crushed stone pile. As the crushed stone is continuously filled, the sleeve 9 is intermittently extruded downwards by the control of the first motor 3, which, together with the bottom of the partitions 40, compacts the crushed stone entering the vibratory hole.

[0041] Specifically, a compression ring 18 is fixedly connected to the bottom of the sleeve 9.

[0042] Through the above technical solution, the crushed stone entering the vibratory punching hole is wrapped by the extrusion ring 18. As the sleeve 9 moves downward, the crushed stone can be concentrated inward and piled up in a pagoda shape by the concave surface formed by the discharge chute 12 and the partition 40, so as to avoid excessive compression of the hole wall of the vibratory punching hole and cause the hole wall to collapse.

[0043] Specifically, the sleeve 9 has several mounting plates 19 equidistantly slidably connected inside. The inner wall of the mounting plate 19 has two first sliding shafts 20 symmetrically slidably connected. One end of each of the two first sliding shafts 20 is fixedly connected to a limit block 22, and the other end of each of the two first sliding shafts 20 is fixedly connected to a top plate 23. The outer wall of each of the two first sliding shafts 20 is fitted with a first spring 21. One end of the first spring 21 is fixedly connected to the mounting plate 19, and the other end of the first spring 21 is fixedly connected to the top plate 23. A linkage unit is provided on one side of the mounting plate 19. The linkage unit includes a second sliding shaft 24, which is fixedly installed on one side of the mounting plate 19. One end of the second sliding shaft 24 extends into the interior of the discharge trough 12 and is fixedly connected to a top block 26. The top of the top block 26 is set as an inclined surface. The outer wall of the second sliding shaft 24 is fitted with a second spring 25, one end of the second spring 25 is fixedly connected to the sleeve 9, and the other end of the second spring 25 is fixedly connected to the top block 26.

[0044] Through the above technical solution, when the extrusion head 17 moves downward, it presses against the inclined surface of the top of several top blocks 26. Under the extrusion of the extrusion head 17, several top blocks 26 move outward simultaneously, pushing several second sliding shafts 24 to move outward simultaneously, pressing several second springs 25. While several second sliding shafts 24 move upward, they push several mounting plates 19 to move outward simultaneously, driving several top plates 23 to move outward simultaneously, compacting the hole wall of the vibratory punching hole, and preventing the hole wall structure of the vibratory punching hole from being unstable and collapsing. When encountering a solidified hole wall, the top plate 23 is retracted by the first spring 21, avoiding excessive extrusion of the solidified hole wall.

[0045] Specifically, the outer wall of the top plate 23 is set as an arc surface; a gear 27 is fixedly connected to the outer wall of the first rotating shaft 7; a slide plate 28 is slidably connected to the bottom of the support plate 6; a rack 29 is fixedly connected to one side of the slide plate 28; the rack 29 meshes with the gear 27; a third motor 30 is fixedly connected to the top of the support plate 6; the output end of the third motor 30 passes through the support plate 6 and is fixedly connected to a crank 31; a connecting shaft 32 is rotatably connected to the bottom of the crank 31; and one end of the connecting shaft 32 is rotatably connected to the slide plate 28.

[0046] Through the above technical solution, while the top plate 23 compacts the hole wall, the third motor 30 is started, driving the crank 31 to rotate. When the long end of the crank 31 rotates to the left, it pulls the connecting shaft 32 to move to the left, causing the slide plate 28 to move to the left, which in turn drives the rack 29 to move to the left. Through the cooperation of the rack 29 and the gear 27, the gear 27 rotates counterclockwise, driving the first rotating shaft 7 to rotate counterclockwise. When the long end of the crank 31 rotates to the right, it similarly drives the rack 29 to move to the right, causing the gear 27 to rotate clockwise. The needle rotates, causing the first rotating shaft 7 to rotate clockwise. This process repeats. When the third motor 30 starts, it drives the first rotating shaft 7 to rotate back and forth, causing the sleeve 9 to rotate back and forth, which in turn drives the top plate 23 to rotate back and forth. As the top plate 23 squeezes and rotates against the hole wall, it smooths the compacted hole wall, improving the smoothness of the hole wall surface and preventing soil from falling into the gravel pile when filling gravel. By setting the outer wall of the top plate 23 to an arc shape, it is easier to improve the smoothing effect on the hole wall and reduce damage to the hole wall.

[0047] Specifically, a material collecting ring 33 is fixedly connected to the top of the sleeve 9. The inner wall of the material collecting ring 33 is set as an annular arc surface. The top of the sleeve box 8 is set as an arc surface. A connecting frame 34 is fixedly connected to the top of the sleeve box 8. A guide ring 35 is fixedly connected to the top of the connecting frame 34. The top of the guide ring 35 is set as an annular arc surface.

[0048] With the above technical solution, when feeding crushed stone, the crushed stone is placed close to the first rotating shaft 7. The guide ring 35 guides the crushed stone, causing it to concentrate at the top of the sleeve 8. With the help of the collecting ring 33, the crushed stone can fall accurately into the first feed trough 10, thereby preventing the crushed stone from sliding directly along the outer edge of the sleeve 9 and colliding with the wall of the vibratory hole, which would cause the soil on the hole wall to landslide.

[0049] Specifically, baffles 36 are fixedly connected to the bottom of both partitions 40, and two sliding grooves 37 are symmetrically opened inside the sleeve 9, with the baffles 36 and the sliding grooves 37 slidably connected.

[0050] With the above technical solution, when the partition 40 rotates, it drives the baffle 36 to slide in the slide groove 37. When the partition 40 is reset, the baffle 36 blocks and protects the mounting groove 41, so as to prevent the crushed stone below from entering the sleeve 9 and damaging the internal parts when it is squeezed.

[0051] A method for operating an auxiliary device for forming vibratory crushed stone piles, applicable to the aforementioned auxiliary device, comprises the following steps:

[0052] S1: The sleeve 9 is moved above the foundation vibratory hole by the control of the vehicle body 1, the first motor 3 is started, and the sleeve 9 is moved downward and enters the vibratory hole;

[0053] S2: Put the crushed stone into the first feed trough 10, start the second motor 13, and control the extrusion head 17 to move up and down repeatedly so that the crushed stone enters the vibratory punch hole in small amounts and multiple times.

[0054] S3: Start the third motor 30 to control the sleeve 9 to rotate back and forth, which in turn drives the top plate 23 to rotate back and forth. In conjunction with the top plate 23 pressing the hole wall, the hole wall is compacted and smoothed at the same time.

[0055] In use, the sleeve 9 is moved above the vibratory punching hole by the vehicle body 1, the first motor 3 is started, driving the lead screw 4 to rotate, causing the connecting block 5 to move downward, driving the support plate 6 to move downward, causing the first rotating shaft 7 to move downward, and driving the sleeve 9 to move downward and enter the vibratory punching hole. Through the two spring plates 38, the two partitions 40 block the discharge chute 12, and the crushed stone is put into the first feed chute 10. When putting in the crushed stone, it is put in close to the first rotating shaft 7. Through the guide ring 35, the crushed stone is guided and concentrated towards the top of the sleeve box 8. With the help of the collecting ring 33, the crushed stone is accurately placed. The crushed stone falls into the first feed trough 10, thus preventing it from sliding directly along the outer edge of the sleeve 9 and colliding with the wall of the vibratory punch hole, which could cause soil landslides. The crushed stone enters the second feed trough 11 along the first feed trough 10 and slides down the inclined surface at the bottom of the second feed trough 11 into the discharge trough 12. The crushed stone is blocked by the partition 40, causing it to remain above the partition 40. The second motor 13 is started, driving the reciprocating screw 14 to rotate, causing the slider 15 to move up and down reciprocally, which in turn drives the ring frame 16 to move up and down reciprocally, causing the extrusion head 17 to move up and down reciprocally. When the extrusion head 17 moves downward, it pushes the crushed stone in the discharge trough 12 downward, and then... Under the pressure of the press head 17, the two partitions 40 rotate downwards simultaneously, pressing the two spring plates 38. When the two partitions 40 move downwards, they lose their obstruction to the discharge chute 12, and the crushed stone in the discharge chute 12 passes through the two partitions 40 and falls into the vibratory punch hole for filling. At the same time, as the press head 17 moves downwards, it blocks the second feed chute 11, stopping the feeding of the second feed chute 11. After the press head 17 moves upwards, the second feed chute 11 can continue to feed, and at the same time, the spring plates 38 rebound, causing the partitions 40 to block the discharge chute 12 again. This process is repeated. With the reciprocating up and down movement of the press head 17, the crushed stone can be fed in small amounts multiple times. The crushed stone enters the vibratory compaction hole to prevent excessive stone from entering at once, which could cause numerous gaps inside and affect the quality of the crushed stone pile. As the crushed stone is continuously filled, the sleeve 9 is intermittently squeezed downwards by the first motor 3, which, together with the bottom of the baffle 40, compacts the crushed stone entering the vibratory compaction hole. When the baffle 40 rotates, it drives the baffle 36 to slide in the slide groove 37. When the baffle 40 returns to its original position, the baffle 36 blocks and protects the mounting groove 41, preventing crushed stone from entering the sleeve 9 and damaging the internal parts when it is squeezed downwards. The crushed stone entering the vibratory compaction hole is wrapped by the compression ring 18. As the sleeve 9 moves downwards,The concave surface formed by the discharge chute 12 and the partition plate 40 allows the crushed stone to concentrate inward and pile up in a pagoda shape, avoiding excessive compression of the hole wall of the vibratory punch and causing the hole wall to collapse. When the extrusion head 17 moves downward, it presses against the inclined surface of the top of several top blocks 26. Under the extrusion of the extrusion head 17, several top blocks 26 move outward simultaneously, pushing several second sliding shafts 24 outward simultaneously, pressing several second springs 25. While several second sliding shafts 24 move upward, they push several mounting plates 19 outward simultaneously, driving several top plates 23 outward simultaneously, compacting the hole wall of the vibratory punch and preventing the hole wall from collapsing due to an unstable structure. When encountering a solidified hole wall, the first spring 21 causes the top plate 23 to retract, avoiding excessive compression of the solidified hole wall. While the top plate 23 is compacting the hole wall, the third motor 30 is started, driving the crank 31. When the long end of crank 31 rotates to the left, it pulls connecting shaft 32 to move to the left, causing slide plate 28 to move to the left, which in turn moves rack 29 to the left. Through the engagement of rack 29 and gear 27, gear 27 rotates counterclockwise, causing the first rotating shaft 7 to rotate counterclockwise. Similarly, when the long end of crank 31 rotates to the right, it moves rack 29 to the right, causing gear 27 to rotate clockwise, which in turn rotates the first rotating shaft 7 clockwise. This process repeats. When the third motor 30 starts, it drives the first rotating shaft 7 to rotate in both directions, causing sleeve 9 to rotate in both directions, which in turn drives top plate 23 to rotate in both directions. As top plate 23 compresses and rotates against the hole wall, it smooths the compacted hole wall, improving the smoothness of the hole wall surface and preventing soil from falling into the gravel pile during filling. By setting the outer wall of top plate 23 to an arc shape, it facilitates the smoothing effect on the hole wall and minimizes damage to the hole wall.
