Description

Technical Field

[0001] This application relates to the field of road construction, and in particular to a method for roadbed construction. Background Technology

[0002] The roadbed is the foundation of a railway track or pavement, a geotechnical structure formed through excavation or filling. Its primary function is to provide the necessary conditions for track or pavement laying and train or vehicle operation, and to bear the static and dynamic loads of the tracks, rolling stock, pavement, and traffic, while simultaneously transferring and dispersing these loads deeper into the ground. In longitudinal profile, the roadbed must ensure the required elevation of the line; in horizontal plane, it connects with bridges and tunnels to form a complete and continuous railway line. In civil engineering, the roadbed occupies a significant position in terms of construction volume, land area, and investment.

[0003] During roadbed construction, some common methods include: cleaning the road surface, laying the base material of the roadbed, laying concrete, and sometimes adding asphalt on the top side of the roadbed.

[0004] In related technologies, although each step in roadbed construction is often separated and different equipment is required, a lot of manpower and material resources are often consumed during the construction process. Frequent equipment changes not only result in low construction efficiency but also high costs. Summary of the Invention

[0005] In order to address the problem of low construction efficiency and high cost caused by frequent equipment changes during roadbed construction in related technologies, this application provides a roadbed construction method.

[0006] This application provides a roadbed construction method using the following technical solution: A roadbed construction method includes the following steps: S1. Sweeping road debris: Provides a loading box, a drive mechanism, and a sweeping mechanism. One side of the loading box is fixedly connected to a tray, and the other side is fixedly connected to a connecting box. The loading box is provided with a partition plate to divide the interior of the loading box into two cavities. A part of the drive mechanism is set in the tray plate, and another part of the drive mechanism is set in the partition plate. A part of the sweeping mechanism is set in the tray plate, and another part is set on the bottom side of the tray plate. The sweeping mechanism includes a sweeping rod, and the sweeping rod is provided with a slide rail to install brushes for sweeping the road surface. S2. Construction of the top surface of the base: One cavity of the loading box is filled with a mixture of lime and crushed stone, and the other cavity is filled with cohesive soil. Both cavities of the loading box are equipped with a discharge mixing mechanism. S3. Compaction and leveling: The connecting box is equipped with a compaction mechanism, which compacts each layer of material laid on the road surface, and the leveling mechanism levels the road surface. S4. Laying concrete: Concrete is filled into the two cavities of the loading box and moved to lay it. The discharge mixing mechanism assists in the discharge of concrete. A linkage mechanism is provided between the driving mechanism and the discharge mixing mechanism.

[0007] By adopting the above technical solution and setting the four steps of S1, S2, S3, and S4, the functions of road surface cleaning, base surface material laying, material compaction and leveling, and subsequent concrete laying are combined. With the movement of the drive mechanism, the sweeping mechanism moves synchronously, sweeping away stubborn debris on the road surface while the material box moves. The material can be unloaded and laid during the movement of the material box, eliminating the need for frequent tool changes and greatly improving construction efficiency and functionality. This application effectively solves the problem of low construction efficiency and high cost caused by frequent equipment changes in related technologies.

[0008] Optionally, the driving mechanism includes a motor and a rotating rod. The motor is fixedly connected to the inner bottom wall of the pallet, and the rotating rod is rotatably connected to the inner wall of the pallet.

A rotating rod is connected between the two drive wheels. A first driven gear that meshes with the first driving gear is coaxially fixedly connected to the outer wall of the rotating rod. An auxiliary wheel is also movably hinged to the compaction mechanism.

[0009] By adopting the above technical solution, the rotating rod is driven to rotate by the action of the motor and the pulley group, which drives the first driving gear to rotate and mesh with the first driven gear, thereby driving the drive wheel to rotate, thus realizing the movement of the equipment in this construction method.

[0010] Optionally, the compaction mechanism includes a connecting frame, a pressure roller, a hinge, and a hydraulic rod. The connecting frame is fixedly connected to the output end of the hydraulic rod, the hydraulic rod is fixedly connected to the inner wall of the connecting box, the two ends of the pressure roller are rotatably connected to the connecting frame, the hinge is mounted on the connecting frame, the auxiliary wheel is movably connected to the hinge, and an adjusting cylinder is movably connected between the auxiliary wheel and the connecting frame.

[0011] By adopting the above technical solution, the lifting and lowering of the connecting frame is controlled by a hydraulic rod, thereby controlling the position of the pressure roller. At the same time, the auxiliary wheel is lowered by adjusting the cylinder, and moves in coordination with the drive wheel.

[0012] Optionally, the linkage mechanism includes a shaft, a second driven gear, a second driving gear, a stacked wheel, and a transmission wheel. The two ends of the shaft are rotatably connected to the upper and lower inner walls of the middle partition, respectively. The second driven gear and the stacked wheel are both coaxially fixedly connected to the shaft. The second driving gear is coaxially fixedly connected to the other end of the rotating rod. The second driving gear and the second driven gear are meshed. There are two transmission wheels, which are located at the top of the two cavities of the loading box. A transmission belt is sleeved between the transmission wheel and the stacked wheel.

[0013] By adopting the above technical solution, the power of the motor is fully utilized through the transmission action between the shaft, the second driven gear, the second driving gear, the stacked gear, and the transmission wheel.

[0014] Optionally, the discharge mixing mechanism includes a central rod, a mixing rod, and a spiral blade. The central rod is rotatably connected to the inner wall of the loading box, the transmission wheel is coaxially and fixedly connected to the central rod, the mixing rod and the spiral blade are both fixedly connected to the outer wall of the central rod, the mixing rod is located above the spiral blade, and a discharge port is provided at the bottom of the loading box.

[0015] By adopting the above technical solution, the setting of the discharge mixing mechanism effectively ensures that the materials inside the two cavities are difficult to stick together, the spiral blades facilitate material discharge, and the mixing rod can improve the uniformity of the materials inside the cavity.

[0016] Optionally, the sweeping mechanism further includes a third driven gear, a third driving gear, and a connecting rod.

The other end of the connecting rod is coaxially and fixedly connected to the third driven gear.

[0017] By adopting the above technical solution, the sweeping mechanism and the drive mechanism are linked. During the movement of the equipment, the road surface can be cleaned to a certain extent. After the material is unloaded, the material can be swept flat, thereby reducing the difficulty of leveling.

[0018] Optionally, multiple sweeping rods are provided and distributed in a circumferential array around the connecting rod, with the highest height of the sweeping rod being lower than the discharge port of the loading box.

[0019] By adopting the above technical solution, the sweeping and leveling function of the sweeping bar has been further improved.

[0020] Optionally, a forward pedal and a reverse pedal are movably connected to the pallet, and both the forward pedal and the reverse pedal are electrically connected to the motor.

[0021] By adopting the above technical solution, the forward and reverse pedals make it easier to control the direction of roadbed construction and facilitate the operation of construction personnel.

[0022] Optionally, the outer wall of the loading box is fixedly connected with a plurality of handles arranged parallel to the pallet.

[0023] By adopting the above technical solution, the handle design makes it easier for construction workers to apply force and control the direction of the equipment.

[0024] Optionally, the top of the loading box is fixedly connected to a feed hopper.

[0025] By adopting the above technical solution, the feeding hopper is designed to facilitate the entry of different materials into the hole, thus completing the material storage function.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting four steps, S1, S2, S3, and S4, the functions of road surface cleaning, base surface material laying, material compaction and leveling, and subsequent concrete laying are combined. As the drive mechanism moves, the sweeping mechanism moves synchronously, sweeping away stubborn debris on the road surface while the loading box moves. Material can be unloaded and laid during the movement of the loading box, eliminating the need for frequent tool changes and greatly improving construction efficiency and functionality. This application effectively solves the problem of low construction efficiency and high cost caused by frequent equipment changes in related technologies. 2. The discharge mixing mechanism effectively ensures that the materials inside the two cavities do not clump together. The spiral blades facilitate material discharge, and the mixing rod can improve the uniformity of the materials inside the cavity. Furthermore, the discharge mixing mechanism is linked with the drive mechanism through a linkage mechanism, making full use of the motor's power, saving energy, and strengthening the linkage between structures. 3. The setting of the leveling mechanism enables the functions of S1 and S3 to be better realized. Compared with related technologies, which require manual time and effort to level and compact the paving material, this method handles the relevant steps more quickly, improves the operation efficiency of the method, and makes it more worry-free and labor-saving for workers, thus meeting people's needs in roadbed construction.

[0038] Reference Figure 1 , Figure 2 and Figure 3 A roadbed construction method includes four steps: S1, cleaning road surface debris; S2, constructing the top surface of the base; S3, compacting and leveling; and S4, laying concrete. These four steps combine the functions of road surface cleaning, base surface material laying, material compaction and leveling, and subsequent concrete laying. With the movement of the drive mechanism 2, the sweeping mechanism 5 moves synchronously, sweeping away stubborn debris on the road surface while the loading box 1 moves. Material can be unloaded and laid during the movement of the loading box 1, eliminating the need for frequent tool changes. This application, to a certain extent, solves the problem of low construction efficiency and high cost caused by frequent equipment changes in related technologies, meeting people's usage needs.

[0039] Specifically, a roadbed construction method includes the following construction steps: S1. Sweeping road debris: A loading box 1, a drive mechanism 2, and a sweeping mechanism 5 are provided. A tray 11 is fixedly connected to one side of the loading box 1, and a connecting box 12 is fixedly connected to the other side. A partition 14 is set inside the loading box 1 to divide the interior of the loading box 1 into two cavities. A part of the drive mechanism 2 is set inside the tray 11, and another part of the drive mechanism 2 is set inside the partition 14. A part of the sweeping mechanism 5 is set inside the tray 11, and another part is set on the bottom side of the tray 11. The sweeping mechanism 5 includes a sweeping rod 54, and a slide rail is provided on the sweeping rod 54 to install brushes for sweeping the road surface. In S1, refer to Figure 4 and Figure 5The drive mechanism 2 includes a motor 21 and a rotating rod 22. The motor 21 is fixedly connected to the inner bottom wall of the support plate 11, and the rotating rod 22 is rotatably connected to the inner wall of the support plate 11. One end of the rotating rod 22 extends into the middle partition 14. A pulley group 23 is connected between the output shaft of the motor 21 and the rotating rod 22. A first drive gear 25 is coaxially fixedly connected to one end of the rotating rod 22. Drive wheels 26 are rotatably connected to both sides of the support plate 11. A rotating rod is connected between the two drive wheels 26. A first driven gear 24 that meshes with the first drive gear 25 is coaxially fixedly connected to the outer wall of the rotating rod. An auxiliary wheel 27 is movably hinged to the compaction mechanism 6. A forward pedal 15 and a backward pedal 16 are movably connected to the support plate 11. Both the forward pedal 15 and the backward pedal 16 are electrically connected to the motor 21.

[0040] Specifically, when moving the loading box 1, the motor 21 is started. The motor 21 and the pulley group 23 drive the rotating rod 22 to rotate, which drives the first driving gear 25 to rotate and mesh with the first driven gear 24, thereby driving the drive wheel 26 to rotate. This allows the loading box 1 to move in different places to complete the unloading. It has strong applicability. During normal movement, the movement is completed by the cooperation between the auxiliary wheel 27 and the drive wheel 26. Before moving, brush bristles are installed on the sweeping rod 54. During the movement, the road surface is cleaned and stubborn objects are removed. The forward pedal 15 and the reverse pedal 16 control the direction of the motor 21, thereby controlling the forward and reverse movement of the equipment.

[0041] It should be noted that the forward pedal 15 and the reverse pedal 16 in this embodiment control the rotation of the motor 21, which is common knowledge to those skilled in the art, and therefore will not be described in detail in this embodiment.

[0042] Furthermore, the outer wall of the loading box 1 is fixedly connected with a plurality of handles arranged parallel to the pallet 11, and the top of the loading box 1 is fixedly connected to the feed hopper 13.

[0043] The handle is designed to allow the operator to apply force and control the direction of the equipment. The feed hopper 13 is designed to allow different materials to enter the hole and complete the material storage function.

[0044] S2. Construction of the top surface of the base: One cavity of the loading box 1 is filled with a mixture of lime and crushed stone, and the other cavity is filled with cohesive soil. Both cavities of the loading box 1 are equipped with a discharge mixing mechanism 4, wherein the mass ratio of lime to crushed stone is 1:13.

[0045] It should be noted that the ratio of lime to crushed stone provided in this embodiment is only a preferred ratio. In other embodiments, it is also possible to set other ratios of lime to crushed stone.

[0046] Reference Figure 3S3, Compaction and Leveling: The connecting box 12 is equipped with a compaction mechanism 6, which compacts each layer of material laid on the road surface, and the leveling mechanism 5 levels the road surface. The compaction mechanism 6 includes a connecting frame 61, a pressure roller 62, a hinge 63, and a hydraulic rod 64. The connecting frame 61 is fixedly connected to the output end of the hydraulic rod 64, the hydraulic rod 64 is fixedly connected to the inner wall of the connecting box 12, the two ends of the pressure roller 62 are rotatably connected to the connecting frame 61, the hinge 63 is mounted on the connecting frame 61, the auxiliary wheel 27 is movably connected to the hinge 63, and an adjusting cylinder 271 is movably connected between the auxiliary wheel 27 and the connecting frame 61.

[0047] When road compaction is required, the hydraulic rod 64 controls the lifting and lowering of the connecting frame 61, thereby controlling the position of the pressure roller 62. It can be lowered to compact the various layers of road material, or raised to prevent the pressure roller 62 from interfering with the movement of the equipment. When the pressure roller 62 is raised, the auxiliary wheel 27 is lowered by adjusting the cylinder 271, which moves in conjunction with the drive wheel 26. When the pressure roller 62 is lowered, it can both compact the road surface and act as an auxiliary moving wheel, moving in conjunction with the drive wheel 26. It has strong overall applicability.

[0048] Reference Figure 3 The linkage mechanism 3 includes a shaft 31, a second driven gear 32, a second driving gear 33, a stacked wheel 34, and a transmission wheel 35. The two ends of the shaft 31 are rotatably connected to the upper and lower inner walls of the partition plate 14, respectively. The second driven gear 32 and the stacked wheel 34 are both coaxially fixedly connected to the shaft 31. The second driving gear 33 is coaxially fixedly connected to the other end of the rotating rod 22. The second driving gear 33 and the second driven gear 32 are meshed. There are two transmission wheels 35, which are set on the top of the two cavities of the loading box 1. A transmission belt is sleeved between the transmission wheel 35 and the stacked wheel 34.

[0049] Reference Figure 3 and Figure 5 The second drive gear 33 rotates through the rotating rod 22, which in turn drives the second driven gear 32 to rotate. The second driven gear 32 then drives the shaft 31 to rotate. Through the transmission action between the stacked wheel 34 and the transmission wheel 35, the linkage between the drive mechanism 2 and the discharge mixing mechanism 4 is strengthened, making full use of the power of the motor 21 and saving energy.

[0050] Reference Figure 3 and Figure 4 S4. Laying concrete: Fill the two cavities of the loading box 1 with concrete and move it to lay it. The discharge mixing mechanism 4 assists in discharging the concrete. A linkage mechanism 3 is set between the drive mechanism 2 and the discharge mixing mechanism 4. The discharge mixing mechanism 4 includes a central rod 41, a mixing rod 42, and a spiral blade 43. The central rod 41 is rotatably connected to the inner wall of the loading box 1. The transmission wheel 35 is coaxially fixedly connected to the central rod 41. The mixing rod 42 and the spiral blade 43 are both fixedly connected to the outer wall of the central rod 41. The mixing rod 42 is located above the spiral blade 43. The bottom of the loading box 1 has a discharge port.

[0051] The discharge mixing mechanism effectively prevents the materials inside the two cavities from sticking together. The spiral blade 43 facilitates material discharge, and the mixing rod 42 effectively improves the uniformity of the materials inside the cavity. During use, the transmission wheel 35 rotates, driving the central rod 41 to rotate, which in turn drives the mixing rod 42 and the spiral blade 43 to rotate, thus completing the mixing and auxiliary transportation of the materials.

[0052] Reference Figure 3 The sweeping mechanism 5 also includes a third driven gear 51, a third driving gear 52 and a connecting rod 53. The third driving gear 52 is coaxially fixedly connected to the rotating rod 22. The connecting rod 53 is rotatably connected to the support plate 11. One end of the connecting rod 53 passes through the support plate 11 and is detachably connected to the sweeping rod 54. The other end of the connecting rod 53 is coaxially fixedly connected to the third driven gear 51. Multiple sweeping rods 54 are provided and are arranged in a circular array around the connecting rod 53. The highest height of the sweeping rod 54 is lower than the discharge port of the loading box 1.

[0053] By linking the sweeping mechanism 5 with the drive mechanism 2, the road surface can be cleaned to a certain extent during the movement of the equipment. After the material is unloaded, the material can be swept flat, reducing the difficulty of leveling and simplifying the leveling operation. The rotating rod 22 rotates the third drive gear 52, which meshes with the third driven gear 51, driving the connecting rod 53 to rotate, which in turn drives the sweeping rod 54 to rotate, making it easier to sweep the material flat. Other tools can also be installed on the sweeping rod 54 to help with leveling, enriching the function of the sweeping rod 54.

[0054] The implementation principle of a roadbed construction method in this application embodiment is as follows: By setting four steps S1, S2, S3, and S4, the functions of road surface cleaning, base surface material laying, material compaction and leveling, and subsequent concrete laying are combined. Specifically, a mixture of lime and gravel and cohesive soil are first filled into different cavities in the loading box 1. As the drive mechanism 2 moves, the motor 21 is started. Through the action of the motor 21 and the pulley group 23, the rotating rod 22 is driven to rotate, which drives the first driving gear 25 to rotate and mesh with the first driven gear 24, thereby driving the drive wheel 26 to rotate. This allows the loading box 1 to move in different places, moving synchronously with the sweeping mechanism 5 to clean the road surface. During the movement of the loading box 1, the material is unloaded, completing the base surface leveling. Before laying the material on the top surface of the base, concrete square piles and steel pipe piles need to be laid out, pressed, and fixed to form the base. After the material is laid on the top surface of the base, the hydraulic rod 64 controls the lifting and lowering of the connecting frame 61, thereby controlling the position of the pressure roller 62. It can be lowered to compact the material of each layer of the road surface. The rotating rod 22 rotates and the third driving gear 52 rotates. The third driving gear 52 meshes with the third driven gear 51, driving the connecting rod 53 to rotate, which in turn drives the sweeping rod 54 to rotate, making it easier to sweep the material level. Most steps of the entire roadbed construction process can be realized by the equipment in this method. The work efficiency is high and the cost is low. There is no need to frequently change the construction equipment. This application effectively solves the problem of low construction efficiency and high cost caused by frequent equipment changes in related technologies.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
