Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of civil engineering construction, in particular to earth compacting equipment suitable for underwater earth compaction, and also to a compaction method. Background Art
[0002] With the increasing number of underwater engineering projects, such as marine resource development, cross-sea bridge construction, port and wharf expansion, and offshore wind farm construction, underwater earthwork compaction has become a critical step in ensuring the stability and safety of engineering structures. Underwater earthwork compaction not only enhances foundation bearing capacity and reduces structural settlement, but also effectively prevents seawater erosion and scouring, ensuring the long-term stability of the project.
[0003] The patent with announcement number CN112779902B discloses a water surface compaction device for civil engineering foundation piles, which can detect the compaction of soil through multiple detection needles, detect the location of soil with large gaps, and at the same time, multiple detection needles can loosen the soil in a small range. In the later stage of the soil being compacted, small spaces are reserved to gather soil and strengthen the compaction of soil. When one of the detection needles detects a loose soil position, the valve corresponding to the detection needle can be started, and the motor drives the shaft to rotate 90 degrees clockwise. At the same time, the blades at the rear end rotate 90 degrees with the shaft, and the soil falls into the storage tank. At the front end of the soil box, the electric slide receives the signal from the detector and drives the punching cylinder to move left and right through the electric slide. The electric slide drives the electric slider to move the punching cylinder to the top of the opened input pipe. After the position of the punching cylinder corresponds to the input pipe, the punching shaft is driven downward by the punching cylinder. After the punching shaft moves downward, it is inserted straight down into the opened input pipe, which can push the soil in the soil storage box into the input pipe. The soil is input from the input pipe to the loose soil position, and the soil can be transported to the loose soil position. The soil can be used as filling soil to replenish the soil in time, strengthen the compaction of the soil, and improve the firmness of the building foundation piles.
[0004] Although the above scheme realizes the accurate filling of soil at a fixed point, the soil is pushed into the input pipe under the action of the punch shaft, and then filled along the input pipe to the position where the soil in the water body is loose. During this process, the soil is in a loose state, and there are large gaps between the soils. After the soil moves out of the input pipe, the flow of the water body will cause some soil to be lost, resulting in a weakening of the soil filling effect. Summary of the Invention

[0015] A compaction method, applied to an earthwork compaction device suitable for underwater earthwork compaction, comprises the following steps:
[0016] S1. Put the soil into the crushing chamber, and the crushing structure crushes the soil, breaking large pieces of soil into small pieces;
[0017] S2. When the soil needs to be filled to the bottom of the water, the partition mechanism works to connect the crushing bin and the gathering bin, and small pieces of soil fall into the gathering bin and the discharge bin;
[0018] S3, then the gathering mechanism is started, and the lower pressing plate moves toward the discharge bin, so that the soil under the lower pressing plate is gathered and compacted toward the discharge bin;
[0019] S4. The punching and discharging structure moves to the top of the discharge port where the soil needs to be discharged. The punching and discharging structure drives the discharge assembly to work, and the discharge assembly discharges the soil from the corresponding discharge port.
[0020] S5. Finally, compact the discharged soil.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. The present invention is provided with a soil storage box, a partition mechanism, a gathering mechanism and a shaping mechanism. The crushing structure in the soil storage box crushes the large pieces of soil put into the crushing bin and converts them into small pieces of soil, effectively preventing the large pieces of soil from clogging the subsequent shaping pipes and other components, ensuring the smooth operation of the equipment and improving the soil processing efficiency. The partition mechanism can separate or connect the crushing bin and the gathering bin. In the soil crushing stage, the partition mechanism separates the two. When feeding is required, the partition mechanism is opened to allow the small pieces of soil to enter the gathering bin smoothly. The lower pressure plate in the gathering mechanism is flat. It moves along the discharge bin and can move toward the discharge bin, concentrating and compacting the soil under the lower pressure plate toward the discharge bin, making the soil denser, reducing the gaps between the soils, and improving the density and stability of the soil. The shaping tube in the shaping structure is connected to the discharge port, and the compacted soil is formed into a cylindrical state through the shaping tube. The surface of the cylindrical soil is relatively smooth. After the soil of this shape falls to the bottom of the water, the flow of the water body has less interference with it, thereby effectively preventing the loose soil from being carried away by the flowing water body and ensuring the soil filling effect.
[0023] 2. The present invention provides two gathering plates and multiple control components. Before the lower pressure plate moves toward the discharge bin, the multiple control components simultaneously apply force to the two gathering plates, so that the two gathering plates are in a state of being away from the lower pressure plate. At this time, the area covered by the lower pressure plate and the gathering plate is the largest, and the soil in a larger range can be included in the extrusion range at one time. When the two gathering plates are in contact with the two inner walls of the gathering bin, as the lower pressure plate moves toward the discharge bin, the multiple control components drive the two gathering plates to move toward the lower pressure plate and keep the gathering plates in contact with the inner wall of the gathering bin. In this process, the soil on the inner wall of the gathering bin is moved by the pushing action of the gathering plates and gathered toward the discharge bin, thereby effectively avoiding soil remaining on the inner wall of the gathering bin.
[0024] 3. The present invention provides a first guide rod, two sliders and two first springs. In the initial state, under the action of the first spring, the two gathering plates are in a state away from the lower pressure plate, so that the area covered by the lower pressure plate and the gathering plates reaches the maximum. When the lower pressure plate moves upward after completing the squeezing and discharge operation of the soil, the elastic potential energy stored in the first spring pushes the gathering plates to gradually move away from the lower pressure plate, so that the gathering plates return to their initial state. When the slider moves to the end of the first guide rod, the gathering plates stop moving. At this time, the area covered by the two gathering plates and the lower pressure plate is reset to the maximum state, ready for the next gathering operation. By utilizing the elastic force of the first spring, the gathering plates can automatically adjust their positions according to the moving state of the lower pressure plate.

[0037] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0038] Reference Figures 1 to 11As shown: a soil compaction equipment suitable for underwater soil compaction, including a soil storage box 1, a partition mechanism 2, a gathering mechanism 3 and a shaping structure 4; the interior of the soil storage box 1 is respectively a crushing bin 11, a gathering bin 12 and a discharge bin 13 from top to bottom, the crushing bin 11 is provided with a crushing structure 14, the gathering bin 12 is a conical contraction shape with a larger top and a smaller bottom, and the lower end of the discharge bin 13 is provided with multiple discharge ports; the partition mechanism 2 is used to separate the crushing bin 11 and the gathering bin 12; the gathering mechanism 3 includes a cover body 31 arranged at the upper end of the soil storage box 1, and the interior of the cover body 31 is provided with a lower pressure plate 32 parallel to the discharge bin 13, and the lower pressure plate 32 is provided with multiple discharge assemblies 34 corresponding to the multiple discharge ports respectively, and the upper end of the cover body 31 is provided with a stamping discharge structure 35 for driving the discharge assembly 34 to work; the multiple discharge ports are all provided with a shaping structure 4, and the shaping structure 4 includes a shaping pipe 41 connected to the discharge port.
[0039] Specifically, the crushing structure 14 and the punching and discharging structure 35 both adopt existing technologies, and the punching and discharging structure 35 can move along multiple discharge ports.
[0040] First, the compacting equipment is installed as a whole on the water surface working platform, and the water surface working platform drives the compacting equipment as a whole to move on the water surface. When the water surface working platform drives the compacting equipment as a whole to move above the top where soil needs to be added, the partition mechanism 2 separates the crushing bin 11 and the gathering bin 12, and then the soil is put into the crushing bin 11. The crushing structure 14 crushes the soil and breaks the large pieces of soil into small pieces to prevent large pieces of soil from clogging the shaping tube 41. When the soil needs to be filled to the bottom of the water, the partition mechanism 2 works to connect the crushing bin 11 and the gathering bin 12. Small pieces of soil fall into the gathering bin 12 under the action of gravity and gather along the inner wall of the conically contracted gathering bin 12 toward the discharge bin 13. Then the gathering mechanism 3 is started, and the lower pressure plate 32 moves toward the discharge bin 13, so that the soil under the lower pressure plate 32 is concentrated and compacted toward the discharge bin 13. The soil becomes denser, and then the stamping discharge structure 35 moves to above the discharge port where the soil needs to be discharged. The stamping discharge structure 35 then drives the discharge assembly 34 to work, and the discharge assembly 34 discharges the soil from the corresponding discharge port. The soil passes through the shaping tube 41 in the shaping structure 4 to form a cylindrical state. At this time, the cylindrical soil surface is relatively smooth. After the soil falls to the bottom of the water, the soil is compacted. Through the cooperation of the lower pressure plate 32, the gathering bin 12 and the discharge bin 13, the soil is preliminarily compacted, which effectively reduces the gap between the soils, improves the density of the soil, and enhances the stability of the soil. The compacted soil is shaped in appearance by the shaping tube 41 to form a cylindrical state with a relatively smooth surface. The flow of water has less interference with the soil, thereby effectively preventing the loose soil from being carried away by the flowing water, and ensuring the soil filling effect.
[0041] Reference Figure 3 and Figure 4As shown: the material gathering mechanism 3 also includes an auxiliary material gathering component 33, the auxiliary material gathering component 33 includes two material gathering plates 331 and multiple control components 332; the two material gathering plates 331 are respectively arranged on both sides of the lower pressure plate 32, and the material gathering plates 331 are slidingly connected to the lower pressure plate 32; multiple control components 332 are equidistantly arranged on the lower pressure plate 32, and the two ends of the control component 332 are respectively connected to the two material gathering plates 331.
[0042] When the partition mechanism 2 is connected to the crushing bin 11 and the gathering bin 12, the soil slides along the inclined inner wall of the gathering bin 12 toward the discharge bin 13. Due to the friction between the inner wall of the gathering bin 12 and the soil, part of the soil will adhere to the inner wall of the gathering bin 12. Therefore, before the lower pressure plate 32 moves toward the discharge bin 13, the multiple control components 332 simultaneously apply force to the two gathering plates 331, so that the two gathering plates 331 are in a state of being away from the lower pressure plate 32. At this time, the area covered by the lower pressure plate 32 and the gathering plate 331 is the largest, so as to squeeze the soil in a larger range. Then the lower pressure plate 32 drives the two gathering plates 331 to move toward the discharge bin 13. When the two gathering plates 331 abut against the two inner walls of the gathering bin 12, the multiple control components 332 are started again. As the lower pressure plate 32 moves toward the discharge bin 13, the multiple control components 332 drive the two gathering plates 331 to move toward the lower pressure plate 32 and keep the gathering plates 331 abut against the inner walls of the gathering bin 12. In this process, the soil on the inner wall of the gathering bin 12 is moved by the pushing action of the gathering plates 331 and gathered toward the discharge bin 13, thereby avoiding soil remaining on the inner wall of the gathering bin 12.
[0043] Reference Figure 4 and Figure 5 As shown: the control component 332 includes a first guide rod 3321 parallel to the lower pressure plate 32 and fixedly connected to the lower pressure plate 32, and sliders 3322 are slidably provided at both ends of the first guide rod 3321, and the sliders 3322 are connected to the gathering plate 331. Two first springs 3323 are also sleeved on the first guide rod 3321, and the two ends of the first spring 3323 respectively abut against the middle part of the slider 3322 and the first guide rod 3321.
[0044] When the lifting lever 332 is lifted up, the lifting lever 332 is lifted up and the support 331 is in a state of being lifted up, so the lifting lever 332 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support 331 is in a state of being lifted up and the support When the lifting mechanism 3321 is lifted up, the lifting mechanism 3322 is lifted up and the support 310 is in the state of being lifted up.
[0045] Reference Figure 3 and Figure 6 As shown: the unloading assembly 34 includes a first unloading column 341 perpendicular to the lower pressure plate 32 and located above the lower pressure plate 32. The first unloading column 341 is movably connected to the lower pressure plate 32. A reset guide assembly 342 is provided at one end of the first unloading column 341. The reset guide assembly 342 is used to drive the first unloading column 341 to reset to above the lower pressure plate 32.
[0046] After the lower pressure plate 32 compacts the soil, when one of the discharge ports moves to just above the bottom of the water where filling is required, the stamping discharge structure 35 moves to the upper end of the discharge assembly 34 corresponding to the discharge port, and the stamping discharge structure 35 applies a force toward the discharge bin 13 on the first discharge column 341, and the first discharge column 341 moves toward the discharge port under the guidance of the reset guide assembly 342. The soil below the first discharge column 341 is pushed by the first discharge column 341 to enter the shaping tube 41 and finally push the soil out of the shaping tube 41. After the stamping discharge structure 35 removes the force on the first discharge column 341, the reset guide assembly 342 drives the first discharge column 341 to reset. At this time, a cavity is formed at the lower end of the first discharge column 341, and the lower pressure plate 32 continues to move downward, squeezing the surrounding soil into the cavity, waiting for the first discharge column 341 to work next time, thereby realizing automatic soil discharge.
[0047] Reference Figure 6 and Figure 7 As shown: the reset guide assembly 342 includes a connecting plate 3421 connected to the end of the first unloading column 341, and a plurality of second guide rods 3422 are movably connected to the connecting plate 3421 at equal intervals, and the second guide rods 3422 are parallel to the first unloading column 341, and each second guide rod 3422 is sleeved with a second spring 3423, and the two ends of the second spring 3423 are respectively in contact with the connecting plate 3421 and the lower pressure plate 32.
[0048] In the initial state, the multiple second springs 3423 are in a naturally extended state, applying a force on the connecting plate 3421 in a direction away from the discharge bin 13. The force is transmitted to the first discharge column 341 through the connecting plate 3421, so that the first discharge column 341 is maintained at the upper end of the lower pressure plate 32, forming a stable initial position. When the stamping discharge structure 35 applies a force toward the discharge bin 13 on the first discharge column 341, the force is transmitted to the connecting plate 3421 through the first discharge column 341, so that the connecting plate 3421 overcomes the force of the multiple second springs 3423 and moves downward along the second guide rod 3422. In this process, the multiple second springs 3423 are gradually The compression and stored elastic potential energy gradually increase. After the unloading operation is completed, the stamping discharge structure 35 removes the force on the first unloading column 341. At this time, the multiple second springs 3423 simultaneously release the stored elastic potential energy and apply an upward force to the connecting plate 3421. Under the joint action of the multiple second springs 3423, the connecting plate 3421 moves upward smoothly along the multiple second guide rods 3422, driving the first unloading column 341 to rise synchronously until it returns to its initial position. In this process, there is no need for the stamping discharge structure 35 to apply a force on the first unloading column 341 away from the discharge bin 13, thereby realizing the automatic reset of the first unloading column 341 after the unloading operation.
[0049] Reference Figure 3 、 Figure 7 and Figure 8 As shown: a vertical groove is opened inside the first material discharge column 341 along the axial direction, and a second material discharge column 343 is movably arranged in the vertical groove. One end of the second material discharge column 343 extends from the first material discharge column 341, and a third spring 344 is sleeved on the second material discharge column 343. The two ends of the third spring 344 are respectively in contact with the bottom and the top of the vertical groove.
[0050] After the first material discharge column 341 squeezes the soil into the shaping tube 41, the first material discharge column 341 still needs to continue to move downward to squeeze the soil out of the shaping tube 41. Therefore, the stroke of the first material discharge column 341 is long, which makes the length of the first material discharge column 341 longer, the second guide rod 3422 in the reset guide assembly 342 is longer, and the stamping discharge structure 35 also needs to be set higher, which causes the center of gravity of the compacting equipment body to be too high. By opening a vertical groove in the interior of the first material discharge column 341 and arranging the second material discharge column 34 in the vertical groove, the first material discharge column 341 is lifted up and the second material discharge column 34 is lifted up. 3. In the initial state, the third spring 344 restricts the second material discharge column 343 within the first material discharge column 341. After the first material discharge column 341 squeezes the soil into the shaping tube 41, the stamping and discharge structure 35 applies a force to the second material discharge column 343. The second material discharge column 343 overcomes the resistance of the third spring 344 and extends out of the first material discharge column 341. The second material discharge column 343 continues to push the soil to move. The first material discharge column 341 and the second material discharge column 343 form a secondary pushing effect, thereby effectively reducing the overall height of the compacting equipment.
[0051] Reference Figure 3 and Figure 9 As shown, the material gathering mechanism 3 includes two downward pressing drive structures 36 , which are respectively arranged at both ends of the lower pressing plate 32 , and the downward pressing drive structures 36 are used to drive the lower pressing plate 32 to move toward the gathering bin 12 .
[0052] Specifically, the downward pressure driving structure 36 includes a connecting column 361 and a downward pressure driver 362. The two ends of the connecting column 361 are respectively connected to the downward pressure plate 32 and the stamping discharge structure 35. The downward pressure driver 362 is fixedly set on the cover body 31 and is connected to the connecting column 361.
[0053] The two ends of the lower pressure plate 32 are simultaneously subjected to the force of the downward pressure driving structure 36, thereby achieving the goal that the two ends of the lower pressure plate 32 maintain synchronous movement, and the lower pressure plate 32 is prevented from tilting due to different local forces.
[0054] Reference Figure 3 and Figure 10 As shown: the partition mechanism 2 includes two partition components 21 and a partition drive structure 22; the two partition components 21 are symmetrically arranged inside the crushing bin 11; the partition drive structure 22 is used to control the two partition components 21 to isolate the connection between the crushing bin 11 and the gathering bin 12.
[0055] Specifically, the partition assembly 21 includes a first rotating shaft 212 and a partition plate 211. The two ends of the first rotating shaft 212 are connected to the soil storage box 1. The partition plate 211 is fixedly connected to the first rotating shaft 212. The partition drive structure 22 includes a first driving plate 221. The first driving plate 221 is parallel to the plane where the two first rotating shafts 212 are located. A second driving plate 222 is provided at both ends of the first driving plate 221. One end of the second driving plate 222 is connected to the first rotating shaft 212, and the other end of the second driving plate 222 is slidingly connected to the first driving plate 221. A first linear driver 223 is provided in the middle of the first driving plate 221. The first linear driver 223 is used to drive the first driving plate 221 to move in a direction perpendicular to the plane where the two first rotating shafts 212 are located.
[0056] If the soil is not crushed, the soil may contain large hard lumps, which will hinder the work of the feeding component 34. Therefore, two partition components 21 and a partition drive structure 22 are provided. Before the soil is put into the crushing bin 11, the partition drive structure 22 drives the two partition components 21 to separate the crushing bin 11 and the gathering bin 12, so that the crushing bin 11 forms an independent space. The soil is put into the crushing bin 11, and the crushing mechanism is started to complete the crushing of the soil in the crushing bin 11. Then the partition drive structure 22 is started again, and the first linear drive 223 drives the first drive plate 221 to move downward. The two ends of the driving plate 221 apply force to the ends of the two second driving plates 222 respectively, so that the second driving plate 222 drives the first rotating shaft 212 to rotate around the axis of the first rotating shaft 212, and the first rotating shaft 212 drives the partition plate 211 to rotate, so that the partition plate 211 rotates from a state parallel to the lower pressure plate 32 to a state parallel to the inner wall of the gathering bin 12, so that the crushed soil can move along the partition plate 211. The partition mechanism 2 can ensure the effective separation of the crushing bin 11 and the gathering bin 12 during the soil crushing process, and prevent uncrushed soil or incompletely crushed soil from entering the gathering bin 12, thereby improving the crushing quality of the soil.
[0057] Reference Figure 3 and Figure 11 As shown: two self-opening and closing components 42 are provided on the shaping tube 41. The two self-opening and closing components 42 are symmetrically arranged about the middle surface of the shaping tube 41. The self-opening and closing components 42 are used to automatically open and close the shaping tube 41.
[0058] Specifically, the self-opening and closing component 42 includes a partition 421 and an elastic telescopic rod 422. The middle part of the partition 421 is axially connected to the shaping tube 41, and the two ends of the elastic telescopic rod 422 are respectively axially connected to the end of the partition 421 and the shaping tube 41.
[0059] When the soil is squeezed into the shaping tube 41, the partition 421 acts as an obstacle to the soil, preventing the soil from falling out of the shaping tube 41 directly. The soil in the shaping tube 41 is squeezed under the action of the partition 421 and the second discharge column 343. When the soil is squeezed to a certain density, the force exerted by the second discharge column 343 on the soil will be transmitted to the partition 421. When the force exerted by the second discharge column 343 on the partition 421 is greater than the force exerted by the elastic telescopic rod 422 on the partition 421, the partition 421 is transmitted around the axial connection between it and the shaping tube 41, and the elastic telescopic rod 422 is compressed. After one end of the second discharge column 343 moves to the end of the shaping tube 41, the soil in the shaping tube 41 is completely discharged. At this time, the partition 421 is only subjected to the force of the elastic telescopic rod 422, so that the partition 421 covers the end of the shaping tube 41 again, thereby preventing water from entering the shaping tube 41.
[0060] A compaction method, applied to an earthwork compaction device suitable for underwater earthwork compaction, comprises the following steps:
[0061] S1. Soil is placed in the crushing chamber 11. The crushing structure 14 crushes the soil, breaking large pieces of soil into small pieces.
[0062] S2. When the soil needs to be filled to the bottom of the water, the partition mechanism 2 works to connect the crushing bin 11 and the gathering bin 12, and small pieces of soil fall into the gathering bin 12 and the discharge bin 13;
[0063] S3, the gathering mechanism 3 is then started, and the lower pressing plate 32 moves toward the discharge bin 13, so that the soil below the lower pressing plate 32 is gathered and compacted toward the discharge bin 13;
[0064] S4. The punching and discharging structure 35 moves to the top of the discharge port where the soil needs to be discharged. The punching and discharging structure 35 drives the discharge assembly 34 to work, and the discharge assembly 34 discharges the soil from the corresponding discharge port.
[0065] S5. Finally, compact the discharged soil.
