Description

TECHNICAL FIELD

[0002] In the field of silt soil pipe network construction, the soil conditions are complex and diverse, which brings great challenges to construction. Silt soil usually has high water content, large void ratio, high compressibility and low strength. The soil particles are filled with a large amount of water, forming a relatively loose and unstable structure. In this structure, there is a relatively stable water film around the soil particles, and the water cannot move freely between the particles, which results in poor drainage performance of silt soil.

[0003] In the prior art, the treatment of silt soil in the ramming operation involved in silt soil pipe network construction mainly relies on a simple reciprocating rammer. However, due to the high water content and low permeability of silt soil, it is difficult to effectively drain the water in the soil by simply relying on ramming force. Although ramming can compress the soil pores to a certain extent, the compressed water cannot be quickly drained, resulting in a high pore water pressure in the soil. When ramming stops, the soil will rebound under the action of pore water pressure, resulting in a significant reduction in the ramming effect. In view of the characteristics of silt soil, the activity of the fill soil cannot be guaranteed during the reciprocating ramming process, and there is no specific monitoring means during the ramming process, so the compaction degree cannot meet the design requirements, and the ramming effect is poor.

DETAILED DESCRIPTION

[0016] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0017] Please refer to Figure 1 to Figure 4The mucky soil pipe network construction compaction degree feedback rammer provided by the application is described as follows. The mucky soil pipe network construction compaction degree feedback rammer comprises a moving frame 10, a main ram head 20, a vibration assembly 30, a transmission assembly 40, a pressure sensor 21 and a matched controller. The bottom end of the moving frame 10 is provided with traveling wheels 11. The top of the moving frame 10 is fixedly provided with an extension structure 13, and the extension end of the extension structure 13 is connected with a ram column 12 extending vertically downward. The main ram head 20 is fixedly connected with the bottom end of the ram column 12 and can descend with the ram column 12 and compact the soil surface. The vibration assembly 30 is slidably arranged on the moving frame 10 in the vertical direction and has a vibration contact part surrounding the outer side of the main ram head 20. The transmission assembly 40 is arranged on the moving frame 10 and connected with the ram column 12 and the vibration assembly 30 respectively. The transmission assembly 40 can drive the vibration assembly 30 to ascend when the ram column 12 descends or drive the vibration assembly 30 to descend and make the vibration contact part contact the soil surface when the ram column 12 ascends. The pressure sensor 21 is arranged at the bottom of the ram head and can monitor the reaction force of the soil on the main ram head 20.

[0018] Specifically, when the vibration contact part contacts the compacted soil surface, the water film around the soil particles is broken by high-frequency vibration, and the activity of small particles is excited.

[0019] Compared with the prior art, the moving frame 10 can move on the soil surface of the mucky soil through the traveling wheels 11, and the extension structure 13 can drive the combination of the ram column 12 and the main ram head 20 to reciprocate in the vertical direction to perform the compacting operation. The vibration assembly 30 is provided with the vibration contact part surrounding the outer side of the main ram head 20. The vibration assembly 30 can contact the soil surface through the vibration contact part and generate high-frequency vibration on the soil surface. The relatively stable water film around the soil particles is broken by the high-frequency vibration, so that the water molecules are more likely to move between the particles, and the drainage and consolidation are accelerated. Meanwhile, the high-frequency vibration energy can excite the activity of small particles, such as sand particles and powder particles, so that the small particles quickly fill the gaps between the large particles under the drive of the vibration energy, thereby improving the compactness of the soil. The transmission assembly 40 can ensure that the vibration contact part is separated from the soil surface when the main ram head 20 descends to perform the compacting operation, and the vibration contact part contacts the soil surface when the main ram head 20 ascends. The two parts work in an interleaved manner and do not interfere with each other, so that the respective advantages of ramming and vibration can be fully utilized to ensure the compacting effect of the mucky soil. In addition, the pressure sensor 21 is installed on the main ram head 20 and matched with the controller, so that the reaction force of the soil can be monitored, which is helpful for timely adjusting the construction parameters and ensuring the construction quality.

[0020] It needs to be explained that the laser range finder 60 can also be arranged on the mobile frame 10, the laser range finder 60 can vertically downwardly project a laser beam and irradiate on the outer side area of the main tamper head 20, and the settlement amount of the compacted soil surface can be monitored, so that the adjustment of the construction parameters is further ensured.

[0021] In some embodiments, the vibration assembly 30 described above can adopt the structure as shown in Figure 1 to Figure 4 Figure 1 to Figure 4 The direction in which the mobile frame 10 travels is set as a first direction, and the horizontal direction perpendicular to the first direction is set as a 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 tamper head 20 along the first direction. Two slide rods 32 are connected to the lifting slide 31 and are arranged along the vertical direction, and each slide rod 32 is in sliding connection with the mobile frame 10. The vibration structure 33 is arranged at the bottom of the lifting slide 31 and can contact the soil surface when the lifting slide 31 descends. A vibration contact part is located on the vibration structure 33.

[0023] The lifting slide 31 can be in sliding connection with the mobile frame 10 in the vertical direction through the slide rods 32. The lifting slide 31 is connected with the vibration structure 33 at the bottom, and the lifting slide 31 can drive the vibration structure 33 to move up and down, and after descending, the vibration structure 33 is in contact with the soil surface. The vibration structure 33 provides high-frequency vibration, which helps to break the relatively stable water film around the soil particles, so that water can more easily move between the particles. For overcoming unevenness, complex soil blocks, gravel, bricks, organic matter, etc., there are a large number of overhead pores between large and small particles. High-frequency vibration can effectively stimulate the activity of small particles, especially sand particles and silt particles, so that they can quickly fill the gaps between large particles under the driving of vibration energy.

[0024] It needs to be explained that the mobile frame 10 has a sliding cavity for the slide rods 32 to slide, and an opening is arranged at the bottom to correspond to the main tamper head 20 and the vibration structure 33. This structure is an adaptive design, which will not be described here.

[0025] In some embodiments, the vibration structure 33 described above can adopt the structure as shown in Figure 1 to Figure 4 Figure 1 to Figure 4 The vibration structure 33 includes a vibration frame 331 and a first vibration motor 333. The vibration frame 331 is provided with two, and each vibration frame 331 is located on the two sides of the main tamper head 20 along the second direction. Each vibration frame 331 is connected with the lifting slide 31 through a first vibration isolation piece 332. The bottom end of each vibration frame 331 is a vibration contact part. The first vibration motor 333 is provided with two, and each first vibration motor 333 is arranged on the vibration frame 331.

[0026] ​​The two vibration frames 331 are arranged on the two sides of the main tamper head 20 along the second direction, which can ensure the surrounding of the main tamper head 20, and the first vibration motor 333 is arranged on each vibration frame 331. The high-frequency vibration generated by the first vibration motor 333 is transmitted to the vibration frame 331, and after the vibration frame 331 contacts the soil surface, the soil is rapidly drained and the soil density is increased through high-frequency vibration.

[0027] Each vibration frame 331 is connected to the lifting slide 31 through the first vibration isolation member 332, so that the vibration of the vibration frame 331 is not transmitted to the lifting slide 31. The first vibration isolation member 332 can be a high-performance and large-damping rubber vibration isolator or a steel wire rope vibration isolator. The vibration frame 331 and the lifting slide 31 can have a small relative displacement, but will not be separated. This technology is prior art and will not be described here.

[0028] In some embodiments, the above-mentioned vibration structure 33 can adopt the structure as shown in Figure 5 and Figure 6 . Referring to Figure 5 and Figure 6 , the vibration structure 33 further comprises a vibration seat 334 and a second vibration motor 336. The vibration seat 334 is located at the front of the mobile frame 10 along the vector direction of the movement of the mobile frame 10, and is connected to the lifting slide 31 through a second vibration isolation member 335. The vibration seat 334 has a mounting surface arranged horizontally at the bottom end, and the mounting surface is uniformly distributed with a sawtooth structure 337. The second vibration motor 336 is arranged on the vibration seat 334.

[0029] The vibration seat 334 is connected to the lifting slide 31, and the vibration seat 334 can move reciprocally in the vertical direction with the lifting slide 31. Before the main tamper head 20 contacts the soil surface, the soil surface is flattened to a certain extent, and the sawtooth structure 337 on the mounting surface can crush the block-shaped objects on the soil surface to provide a basis for subsequent tampering of the main tamper head 20, thereby ensuring the tampering effect. In addition, the sawtooth structure 337 can penetrate the soil surface to form a plurality of sawtooth grooves or sawtooth openings on the soil surface. After subsequent tampering, these grooves or openings will still have a certain reservation, which further ensures the effect of accelerating drainage.

[0030] Each vibration seat 334 is connected to the lifting slide 31 through the second vibration isolation member 335, so that the vibration of the vibration seat 334 is not transmitted to the lifting slide 31. The second vibration isolation member 335 can be a high-performance and large-damping rubber vibration isolator or a steel wire rope vibration isolator. The vibration seat 334 and the lifting slide 31 can have a small relative displacement, but will not be separated. This technology is prior art and will not be described here.

[0031] In some embodiments, the above-mentioned transmission assembly 40 can adopt the structure as shown in 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 is engaged with the large gear 432, and the second rack 42 is engaged with the small gear 433. This structure can reduce the stroke of the vibration assembly 30 in the vertical direction, thereby reducing the gravity work of the vibration assembly 30 to some extent to reduce the consumption of energy. In addition, this structure can relatively reduce the height of the lifting slide 31. The highest position to which the lifting slide 31 can rise is smaller than the highest position to which the main rammer head 20 can rise. Based on this, the vertical position of the main rammer head 20, i.e., the extension amount of the telescopic structure 13, can be adjusted to control the vertical position of the lifting slide 31. The height of the lifting slide 31 can be slightly higher than the drawing surface, thereby ensuring that the vibration seat 334 in front of the lifting slide 31 can push the soil surface in the horizontal direction during the forward movement of the moving frame 10, thereby facilitating the ramming work of the main rammer head 20. Meanwhile, the plurality of grooves formed on the soil surface by the sawtooth structures 337 facilitate the subsequent drainage process and the transmission of high-frequency vibration.

[0036] In some embodiments, for the ramming work in the trench, the moving frame 10 can be moved in the first direction, and the second direction is perpendicular to the first direction. Figure 1 、 Figure 9 The moving frame 10 can be moved in the first direction, and the second direction is perpendicular to the first direction.

[0037] The silt pipe network construction compaction degree feedback rammer further comprises side ramming structures 50. The side ramming structures 50 are provided in two. The two side ramming structures 50 are respectively arranged on the two sides of the main rammer head 20 along the second direction and are located at the rear of the moving frame 10 along the moving direction of the moving frame 10. Each side ramming structure 50 has a side ramming part that can horizontally extend outward along the second direction. The side ramming structures 50 can be driven by the main rammer head 20 when the main rammer head 20 descends and rams the bottom surface of the trench, and the side ramming structures 50 can perform ramming work on the side walls of the trench through the side ramming parts.

[0038] The side ramming structures 50 can mainly adapt to the trench construction work. The two side ramming structures 50 can respectively ram the two side walls of the trench, thereby ensuring the coverage of the bottom surface and the side walls of the trench and ensuring the ramming effect.

[0039] In some embodiments, the above-mentioned side ramming structures 50 can adopt the structure as shown in Figure 9Each side tamping structure 50 comprises a secondary tamper head 51, a guide rod 52 and a spring 53. The secondary tamper head 51 is slidingly arranged on the moving frame 10 in a sliding cavity along the second direction. The secondary tamper head 51 is a side tamping part. The guide rod 52 is provided with at least two, each of which is arranged along the second direction and is spaced apart along the first direction. Each guide rod 52 is located in the sliding cavity and is connected to the moving frame 10 at both ends. Each guide rod 52 is slidingly connected with a sliding block 54 on the secondary tamper head 51. The spring 53 is provided with a plurality of, each of which corresponds to each guide rod 52. One end of each spring 53 abuts against the sliding block 54, which can continuously push the secondary tamper head 51, so that the secondary tamper head 51 has a tendency to move into the moving frame 10.

[0040] The secondary tamper head 51 is provided with a first inclined surface part 55 at one end inside the moving frame 10. Correspondingly, the wedge block 22 is connected to the main tamper head 20, and the wedge block 22 has a second inclined surface part 23 which can be adapted to the first inclined surface part 55. The wedge block 22 and the main tamper head 20 can be bolted, which can be easily disassembled. When construction in the trench is needed, the wedge block 22 can be fixedly installed, and when the trench is not under construction, the wedge block 22 can be removed.

[0041] Specifically, after the main tamper head 20 descends, the wedge block 22 is driven to descend, the second inclined surface part 23 on the wedge block 22 is adapted to the first inclined surface part 55 on the secondary tamper head 51, and the secondary tamper head 51 is pushed to move outward along the second direction through the inclined surface structure, so as to make the secondary tamper head 51 tamp the side wall of the trench. The power of the secondary tamper head 51 comes from the main tamper head 20, thereby reducing the use of the power source, enhancing the linkage, and importantly improving the adaptability.

[0042] The above merely describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
