Description

Technical Field

[0001] This invention belongs to the technical field of compaction equipment for silty soil pipeline construction, specifically relating to a compaction feedback compaction machine for silty soil pipeline construction. Background Technology

[0002] In the field of pipeline construction using silty soil, the complex and diverse soil conditions present significant challenges. Silty soil typically exhibits characteristics such as high water content, large void ratio, high compressibility, and low strength. The spaces between soil particles are filled with a large amount of water, forming a relatively loose and unstable structure. Within this structure, a relatively stable water film binds the soil particles, hindering the free movement of water between them. This results in extremely poor drainage performance of silty soil.

[0003] In existing technologies, the compaction work involved in pipeline construction in silty soil mainly relies on simple reciprocating compactors to treat the silt. However, the high water content and low permeability of silty soil make it difficult to effectively remove moisture from the soil using only compaction force. Although compaction can compress soil pores to some extent, the compressed water cannot be quickly discharged, creating high pore water pressure within the soil. When compaction stops, the soil rebounds under the influence of pore water pressure, significantly reducing the compaction effect. Given the characteristics of silty soil, the reciprocating compaction process cannot guarantee the poor activity of the fill soil, and there are no specific monitoring methods during compaction, thus failing to achieve the designed density and resulting in poor compaction effect. Furthermore, pipeline construction involves trenches, and there is a lack of effective compaction methods for the sidewalls of these trenches. Summary of the Invention

[0004] This invention provides a compaction feedback rammer for silty soil pipeline construction, which aims to solve the problem of poor compaction results caused by the inability of existing rammers to match the soil type in existing silty soil pipeline construction compaction operations.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a silty soil pipeline construction compaction feedback tamping machine, comprising: A mobile frame with wheels at the bottom; a telescopic structure is fixed to the top of the mobile frame, and a vertically extending ramming column is connected to the telescopic end of the telescopic structure. The main tamping head is fixedly connected to the bottom end of the tamping column and is used to move down with the tamping column and compact the soil surface; The vibration assembly is slidably mounted on the mobile frame along the vertical direction and has a vibration contact portion surrounding the outside of the main ramming head; A transmission assembly is mounted on the mobile frame and is connected to the tamping column and the vibration assembly respectively. The transmission assembly is used to drive the vibration assembly to move upward when the tamping column moves downward, or to drive the vibration assembly to move downward when the tamping column moves upward, so that the vibration contact part contacts the soil surface. A pressure sensor is installed at the bottom of the ramming head to monitor the soil reaction force on the main ramming head; Matching controller; As the vibrating contact part comes into contact with the compacted soil surface, the water film binding around the soil particles is broken by high-frequency vibration, and the activity of the small particles is stimulated.

[0006] In one possible implementation, the direction of travel of the mobile rack is defined as a first direction, and the horizontal direction perpendicular to the first direction is defined as a second direction; The vibration assembly includes: A lifting slide is located outside the main ramming head along the first direction; two slide rods are connected to the lifting slide along the vertical direction, and each slide rod is slidably connected to the mobile frame; A vibration structure is provided at the bottom of the lifting slide, for descending with the lifting slide and contacting the soil surface; the vibration contact part is located on the vibration structure.

[0007] In one possible implementation, the vibrating structure includes: Two vibrating frames are provided, each located on both sides of the main tamping head along the second direction; each vibrating frame is connected to the lifting slide via a first vibration isolator; the bottom end of each vibrating frame is the vibration contact part; There are two first vibration motors, each of which is mounted on the vibration frame.

[0008] In one possible implementation, the vibrating structure further includes: The vibration seat is located at the front of the mobile frame along the vector direction of the movement of the mobile frame, and is connected to the lifting slide seat through a second vibration isolation member; the bottom end of the vibration seat has a horizontally arranged mounting surface, and the mounting surface is evenly distributed with serrated structures; The second vibration motor is mounted on the vibration base.

[0009] In one possible implementation, the transmission assembly includes: The first rack is fixed on the ramming column in a vertical direction and has a first tooth surface facing outward; The second rack is fixed on the lifting slide along the vertical direction and has a second tooth surface corresponding to the first tooth surface; A gear component is rotatably mounted on the movable frame and located between the first rack and the second rack. The gear component is used to transmit power to the second rack during the lifting and lowering of the first rack, so that the first rack and the second rack move relative to each other or move in opposite directions.

[0010] In one possible implementation, the gear component includes: The rotating shaft is horizontally rotatably mounted on the movable frame; The large gear is coaxially connected to the rotating shaft and meshes with the first tooth surface of the first rack; The pinion is coaxially connected to the rotating shaft and spaced apart from the large gear. The pinion meshes with the second tooth surface of the second rack.

[0011] In one possible implementation, the direction of travel of the mobile rack is defined as a first direction, and the horizontal direction perpendicular to the first direction is defined as a second direction; The silty soil pipeline construction compaction feedback tamping machine also includes side tamping structures. There are two side tamping structures, which are respectively arranged on both sides of the main tamping head along the second direction and located at the rear of the mobile frame along the traveling direction of the mobile frame. Each side tamping structure has a side tamping part that can extend horizontally outward along the second direction. Each side tamping structure is driven by the main tamping head when the main tamping head moves down and tamps the bottom surface of the trench, and performs tamping operations on the side walls of the trench through each side tamping part.

[0012] In one possible implementation, each of the side-compacted structures includes: A secondary tamping head is slidably disposed in a sliding cavity on the movable frame along the second direction; the secondary tamping head is the side compaction part. At least two guide rods are provided, each guide rod is arranged along the second direction and spaced apart along the first direction; each guide rod is located in the sliding cavity and its two ends are connected to the movable frame; each guide rod is slidably connected to the sliding block on the auxiliary ramming head; Multiple springs are provided, each spring corresponding to one of the guide rods. One end of each spring abuts against the sliding block to continuously push the auxiliary ramming head, so that the auxiliary ramming head has a tendency to move inward into the moving frame. The auxiliary ramming head has a first inclined surface at one end inside the mobile frame; a wedge-shaped block is connected to the main ramming head, and the wedge-shaped block has a second inclined surface that can be adapted to the first inclined surface.

[0013] The silty soil pipeline construction compaction feedback rammer provided in this implementation, compared with existing technologies, allows the mobile frame to move on the silty soil surface via wheels. Simultaneously, the telescopic structure drives the combination of the rammer column and the main rammer head to reciprocate vertically for compaction. The vibrating component has a vibrating contact part surrounding the main rammer head. This contact part contacts the soil surface and generates high-frequency vibration. This high-frequency vibration breaks the relatively stable water film binding around soil particles, making it easier for water molecules to move within the particles and accelerating drainage and consolidation. Simultaneously, driven by the high-frequency vibration energy, the activity of small particles, such as sand and silt, is stimulated, causing them to quickly fill the gaps between larger particles, thereby increasing the soil density. The transmission assembly ensures that when the main tamper head descends for compaction, the vibrating contact part disengages from the soil surface, while during the upward movement, the vibrating contact part contacts the soil surface. This alternating operation prevents interference and fully leverages the advantages of both impact and vibration to ensure effective compaction of silty soil. Furthermore, a pressure sensor installed on the main tamper head, in conjunction with the controller, monitors soil reaction forces, facilitating timely adjustments to construction parameters and ensuring construction quality. Additionally, the included side compaction components are suitable for trench compaction operations; while the main tamper head impacts the trench bottom, the auxiliary tampers also impact the trench sidewalls, thus adapting to trench compaction needs.

[0016] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] Please refer to the following: Figures 1 to 4The present invention will now describe the silty soil pipeline network compaction feedback tamping machine provided by the present invention. The silty soil pipeline network compaction feedback tamping machine includes a mobile frame 10, a main tamping head 20, a vibration assembly 30, a transmission assembly 40, a pressure sensor 21, and a matching controller. The mobile frame 10 has wheels 11 at its bottom. A telescopic structure 13 is fixedly installed at the top of the mobile frame 10, and a vertically extending tamping column 12 is connected to the telescopic end of the telescopic structure 13. The main tamping head 20 is fixedly connected to the bottom end of the tamping column 12 and can move downwards with the tamping column 12 to compact the soil surface. The vibration assembly 30 is slidably mounted on the mobile frame 10 along the vertical direction and has a vibration contact portion surrounding the outside of the main tamping head 20. The transmission assembly 40 is mounted on the movable frame 10 and is connected to both the ramming column 12 and the vibration assembly 30. The transmission assembly 40 can drive the vibration assembly 30 upward when the ramming column 12 moves downward, or drive the vibration assembly 30 downward when the ramming column 12 moves upward, causing the vibration contact part to contact the soil surface. The pressure sensor 21 is located at the bottom of the ramming head and can monitor the soil reaction force on the main ramming head 20.

[0018] Specifically, as the vibrating contact part comes into contact with the compacted soil surface, the water film binding around the soil particles is broken by high-frequency vibration, and the activity of small particles is stimulated.

[0019] The silty soil pipeline construction compaction feedback rammer provided in this embodiment, compared with the prior art, allows the mobile frame 10 to move on the silty soil surface via the traveling wheels 11. Simultaneously, the telescopic structure 13 drives the assembly of the rammer column 12 and the main rammer head 20 to reciprocate vertically for compaction. The vibration component 30 has a vibration contact part surrounding the main rammer head 20. The vibration component 30 contacts the soil surface through the vibration contact part and generates high-frequency vibration. This high-frequency vibration breaks the relatively stable water film binding around soil particles, making it easier for water molecules to move within the particles and accelerating drainage and consolidation. Simultaneously, driven by the high-frequency vibration energy, the activity of small particles, such as sand and silt, is stimulated, causing them to quickly fill the gaps between large particles under the drive of the vibration energy, thereby increasing the soil density. The transmission assembly 40 ensures that when the main tamping head 20 moves downwards for compaction, the vibrating contact part disengages from the soil surface, while during the upward movement, the vibrating contact part contacts the soil surface. This alternating operation ensures that the two processes do not interfere with each other, fully utilizing the advantages of both impact and vibration to guarantee the compaction effect of the silty soil. Furthermore, a pressure sensor 21 is installed on the main tamping head 20, working in conjunction with the controller, to monitor the soil reaction force. This allows for timely adjustment of construction parameters and ensures construction quality.

[0020] It should be noted that a laser rangefinder 60 can also be installed on the mobile frame 10. The laser rangefinder 60 can project a laser beam vertically downward and illuminate the area outside the main tamping head 20, which can monitor the settlement of the compacted soil surface and further ensure the adjustment of construction parameters.

[0021] In some embodiments, the vibration component 30 described above may employ, for example... Figures 1 to 4 The structure shown. See also Figures 1 to 4 The direction in which the mobile frame 10 travels is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction.

[0022] The vibration assembly 30 includes a lifting slide 31 and a vibration structure 33. The lifting slide 31 is located outside the main tamping head 20 along a first direction. Two vertically arranged slide rods 32 are connected to the lifting slide 31, and each slide rod 32 is slidably connected to the moving frame 10. The vibration structure 33 is located at the bottom of the lifting slide 31 and can descend with the lifting slide 31 to contact the soil surface. The vibration contact part is located on the vibration structure 33.

[0023] The lifting slide 31 can be vertically connected to the movable frame 10 via the slide rod 32. The bottom of the lifting slide 31 is connected to the vibration structure 33, which drives the vibration structure 33 to move up and down. Upon descent, the vibration structure 33 contacts the soil surface. The vibration structure 33 provides high-frequency vibration, which helps break the relatively stable water film binding around soil particles, making it easier for water to move between particles. This is effective in overcoming unevenness and complex compositions such as soil clods, gravel, bricks, and organic matter, where there are numerous voids between particles of varying sizes. High-frequency vibration effectively stimulates the activity of small particles, especially sand and silt, causing them to quickly fill the voids between larger particles under the drive of vibrational energy.

[0024] It should be noted that the mobile frame 10 has a sliding cavity for the sliding rod 32 to slide, and an opening is provided at the bottom to correspond to the main tamping head 20 and the vibration structure 33. This structure is an adaptive design and will not be described in detail here.

[0025] In some embodiments, the vibration structure 33 described above can be as follows: Figures 1 to 4 The structure shown. See also Figures 1 to 4 The vibration structure 33 includes a vibration frame 331 and a first vibration motor 333. Two vibration frames 331 are provided, each located on either side of the main ramming head 20 along the second direction. Each vibration frame 331 is connected to the lifting slide 31 via a first vibration isolator 332. The bottom end of each vibration frame 331 is a vibration contact part. Two first vibration motors 333 are provided, each mounted on a vibration frame 331.

[0026] Two vibrating frames 331 are provided and arranged on both sides of the main tamping head 20 along the second direction to ensure the enclosure of the main tamping head 20. Each vibrating frame 331 is equipped with a first vibrating motor 333. The high-frequency vibration generated by the first vibrating motor 333 is transmitted to the vibrating frame 331. After the vibrating frame 331 comes into contact with the soil surface, it performs rapid drainage and increases the compaction of the soil through high-frequency vibration.

[0027] Each vibration frame 331 is connected to the lifting slide 31 via a first vibration isolator 332, which prevents the vibration of the vibration frame 331 from being transmitted to the lifting slide 31. The first vibration isolator 332 can be a high-performance, high-damping rubber vibration isolator or a wire rope vibration isolator. The vibration frame 331 and the lifting slide 31 can undergo small relative displacement, but they will not separate. This technology is existing technology and will not be described in detail here.

[0028] In some embodiments, the vibration structure 33 described above can be as follows: Figure 5 and Figure 6 The structure shown. See also Figure 5 and Figure 6 The vibration structure 33 also includes a vibration seat 334 and a second vibration motor 336. The vibration seat 334 is located at the front of the moving frame 10 along the vector direction of movement of the moving frame 10, and is connected to the lifting slide 31 through a second vibration isolator 335. The bottom end of the vibration seat 334 has a horizontally arranged mounting surface, on which serrated structures 337 are evenly distributed. The second vibration motor 336 is mounted on the vibration seat 334.

[0029] The vibrating seat 334 is connected to the lifting slide 31. The vibrating seat 334 can reciprocate vertically with the lifting slide 31, leveling the surface to a certain extent before the main tamping head 20 contacts the surface. Simultaneously, the serrated structure 337 on the mounting surface breaks up blocky objects on the surface, providing a foundation for subsequent tamping by the main tamping head 20 and ensuring a good compaction effect. Furthermore, the serrated structure 337 can penetrate the soil surface, creating multiple serrated grooves or openings. After subsequent tamping, these grooves or openings will remain to some extent, further accelerating drainage.

[0030] Each vibrating seat 334 is connected to the lifting slide 31 via a second vibration isolator 335, which prevents the vibration of the vibrating seat 334 from being transmitted to the lifting slide 31. The second vibration isolator 335 can be a high-performance, high-damping rubber vibration isolator or a wire rope vibration isolator. The vibrating seat 334 and the lifting slide 31 can undergo small relative displacement, but they will not separate. This technology is existing technology and will not be described in detail here.

[0031] In some embodiments, the transmission component 40 may employ, for example... Figure 1 and Figure 5The structure shown. See also Figure 1 and Figure 5 The transmission assembly 40 includes a first rack 41, a second rack 42, and a gear 43. The first rack 41 is fixed vertically on the ramming column 12 and has a first tooth surface facing outwards. The second rack 42 is fixed vertically on the lifting slide 31 and has a second tooth surface corresponding to the first tooth surface. The gear 43 is rotatably mounted on the movable frame 10 and located between the first rack 41 and the second rack 42. The gear 43 can transmit power to the second rack 42 during the lifting and lowering of the first rack 41, causing the first rack 41 and the second rack 42 to move relative to each other or in opposite directions.

[0032] By combining the first rack 41, the second rack 42, and the gear component 43, the lifting power of the vibration assembly 30 can be ensured to come from the ramming column 12, and then from the telescopic structure 13, thus saving power. Furthermore, this combined structure ensures that the vibration assembly 30 moves upwards during the downward movement of the main ramming head 20, and downwards during the upward movement of the main ramming head 20, avoiding interference between the two. It also ensures that vibration and compaction are independent operations, guaranteeing the compaction effect.

[0033] It should be noted that a sliding space needs to be provided on the movable frame 10 for the vertical guidance of the second rack 42 to ensure the stable movement of the second rack 42.

[0034] In some embodiments, the gear component 43 may be as follows: Figure 5 The structure shown. See also Figure 5 The gear component 43 includes a rotating shaft 431, a large gear 432, and a small gear 433. The rotating shaft 431 is horizontally rotatably mounted on the movable frame 10. The large gear 432 is coaxially connected to the rotating shaft 431 and meshes with the first tooth surface of the first rack 41. The small gear 433 is coaxially connected to the rotating shaft 431 and spaced apart from the large gear 432, and meshes with the second tooth surface of the second rack 42.

[0035] The diameter of the large gear 432 is larger than that of the small gear 433. The first rack 41 meshes with the large gear 432, and the second rack 42 meshes with the small gear 433. This structure can reduce the vertical stroke of the vibration component 30, thereby reducing the work done by gravity of the vibration component 30 to a certain extent and reducing energy consumption. In addition, this structure can relatively reduce the height of the lifting slide 31. The highest position that the lifting slide 31 can rise to is less than the highest position that the main tamping head 20 can rise to. Based on this, the vertical position of the main tamping head 20 can be adjusted, that is, the amount of extension and retraction of the telescopic structure 13 can be adjusted, so that the vertical position of the lifting slide 31 can be controlled, and the height of the lifting slide 31 can be slightly higher than the drawing. This ensures that the vibration seat 334 in front of the lifting slide 31 can push the soil surface horizontally as the moving frame 10 moves forward, which facilitates the compaction operation of the main tamping head 20. At the same time, multiple grooves are formed on the soil surface by the sawtooth structures 337 to facilitate the subsequent drainage process and the transmission of high-frequency vibration.

[0036] In some embodiments, for compaction work within the trench, see [reference needed]. Figure 1 , Figure 9 The direction in which the mobile frame 10 travels is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction.

[0037] The silty soil pipeline construction compaction feedback rammer also includes two side compaction structures 50. These two side compaction structures 50 are respectively positioned on both sides of the main rammer head 20 along a second direction and located at the rear of the mobile frame 10 along its travel direction. Each side compaction structure 50 has a side compaction section that can extend horizontally outward along the second direction. When the main rammer head 20 descends and compacts the bottom of the trench, each side compaction structure 50 is driven by the main rammer head 20 to compact the sidewalls of the trench through its respective side compaction section.

[0038] The side compaction structure 50 is mainly designed to ensure that the trench construction operation is suitable. By using two side compaction structures 50, the two side walls of the trench can be compacted respectively, thereby ensuring the coverage of the bottom and side walls of the trench and ensuring the compaction effect.

[0039] In some embodiments, the aforementioned side-compacting structure 50 may employ, as follows: Figure 9Each side-compacting structure 50 includes a secondary tamping head 51, a guide rod 52, and a spring 53. The secondary tamping head 51 is slidably disposed in a sliding cavity on the movable frame 10 along a second direction. The secondary tamping head 51 is the side-compacting part. At least two guide rods 52 are provided, each guide rod 52 is disposed along the second direction and spaced apart along the first direction. Each guide rod 52 is located in the sliding cavity and its two ends are connected to the movable frame 10. Each guide rod 52 is slidably connected to a sliding block 54 on the secondary tamping head 51. Multiple springs 53 are provided, each spring 53 corresponding to each guide rod 52. One end of each spring 53 abuts against the sliding block 54, which can continuously push the secondary tamping head 51, so that the secondary tamping head 51 has a tendency to move inward into the movable frame 10.

[0040] The auxiliary tamping head 51, located inside the mobile frame 10, has a first inclined surface 55 at one end. Correspondingly, a wedge block 22 is connected to the main tamping head 20, and the wedge block 22 has a second inclined surface 23 that can be adapted to the first inclined surface 55. The wedge block 22 and the main tamping head 20 can be bolted together for easy assembly and disassembly. When construction is required in the trench, the wedge block 22 can be fixedly installed; when trench construction is not involved, the wedge block 22 can be removed.

[0041] Specifically, after the main tamping head 20 descends, it drives the wedge block 22 to descend as well. The second inclined surface 23 on the wedge block 22 is adapted to the first inclined surface 55 on the auxiliary tamping head 51, and the inclined surface structure pushes the auxiliary tamping head 51 to move outward along the second direction, thereby enabling the auxiliary tamping head 51 to tampe the sidewall of the trench. The auxiliary tamping head 51 is powered by the main tamping head 20, thus reducing the power source required, enhancing linkage, and importantly, improving adaptability.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
