Description

Technical Field

[0001] The present invention belongs to the technical field of mixed material grouting, and particularly relates to an integrated device for mixing and grouting a water-stable structural layer. Background Art

[0002] The water-stable layer is made of cement-solidified graded crushed stones and is completed through compaction and curing. The water-stable layer has high strength, stiffness, and stability. For an asphalt pavement, the water-stable layer is the main load-bearing layer of the entire road structure and an important structure to ensure the stability of the entire road structure. By grouting on both sides of the water-stable structural layer road, the density and strength of the base edge and the joint surface can be effectively improved, ensuring the construction quality.

[0003] During the construction of the water-stable layer, grouting treatment is carried out on both sides of the road using cement to enhance the stability and load-bearing capacity of the road structure. Among them, cement is a key material formed by mixing clay powder and water.

[0004] However, during the process of mixing clay powder and water in the existing device to prepare cement, all the clay powder is first poured into the mixing barrel, and then water is added to the mixing barrel. In the initial stage, it is difficult to quickly and evenly penetrate into the interior of the clay powder, resulting in a rapid stratification phenomenon between the cement and the water. This stratification phenomenon poses a huge challenge to the mixing structure in the subsequent mixing process. It is difficult for the mixing blades to effectively mix the cement and water at different levels evenly, not only prolonging the mixing time, reducing the production efficiency, but also possibly causing the quality of the prepared cement to fail to meet the standards, thereby affecting the construction quality of the water-stable layer and the overall performance of the road.

[0005] Therefore, the present invention provides an integrated device for mixing and grouting a water-stable structural layer. Summary of the Invention

The uniform water injection creates good conditions for the full mixing of mud powder and water, helps to form a uniform cement slurry, and avoids the situation that part of the mud powder is not fully hydrated due to stratification, thus ensuring that the prepared cement meets the quality standards and providing high-quality raw materials for the subsequent construction of the water-stable layer.

[0020] 3. For the water-stable structure layer mixing and grouting integrated device of the present invention, the revolution of the arc-shaped extrusion rod also drives the connection block and the rotating rod as a whole to revolve, so that each water column in the path of the mixing mechanism during revolution; under the combined action of revolution and rotation of the mixing mechanism, the mud powder and water are stirred in all directions and at multiple angles, enabling the mud powder and water to be fully and evenly mixed, quickly forming a high-quality slurry, and improving the mixing efficiency and effect.

Detailed implementation manners

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] Such as Figures 1 to 11As shown in the figure, the present invention provides a technical solution: a water-stable structure layer mixing and grouting integrated device, including a vehicle body 1, a mixing barrel 2 is fixedly installed on the top of the vehicle body 1, telescopic mechanisms 3 are fixedly connected to both sides of the vehicle body 1, sprayers 6 are fixedly connected to one ends of the telescopic mechanisms 3, a plurality of rotating hollow wheel bodies 7 are fixedly communicated with the bottoms of the sprayers 6, a plurality of grouting insertion pipes 8 are fixedly communicated with the outer walls of each rotating hollow wheel body 7, bellows 4 are fixedly communicated with the tops of the sprayers 6, one ends of the bellows 4 away from the sprayers 6 are fixedly connected to the bottom ends of the mixing barrels 2, electric valves 5 are arranged outside the bellows 4, a water injection assembly for evenly adding water to various areas inside the mixing barrel 2 is arranged inside the mixing barrel 2, and a mixing assembly for fully stirring the mud powder and water is also arranged inside the mixing barrel 2.

[0036] During operation: In order to solve the problem that in the existing device, when preparing cement by mixing mud powder and water, due to the difficulty of the initial added water to quickly penetrate the mud powder, resulting in stratification, making the mixing difficult, the mixing time long, the efficiency low, and the quality of the cement may not meet the standard, thus affecting the construction of the water-stable layer and the road performance; when this device is specifically used, first add the prepared mud powder into the mixing barrel 2, and then start the water injection assembly, so that the mud powder in various areas inside the mixing barrel 2 can be evenly injected with water, avoiding the stratification phenomenon caused by the difficulty of water to quickly penetrate into the mud powder under the traditional water addition method. After the water injection is completed, start the mixing assembly. The mixing assembly performs full stirring on the mud powder and water through rotational movement, enabling the mud powder to quickly mix with water to form a uniform slurry required for laying the water-stable layer on both sides of the road. After the slurry is prepared inside the mixing barrel 2; the vehicle body 1 slowly travels along the center position of the road. During the traveling process, control the electric valve 5 to open. Under the action of gravity and possible pumping assistance, the slurry enters the inside of the sprayer 6 through the bellows 4; subsequently, the slurry is preliminarily distributed inside the sprayer 6 and then transported into the inside of each rotating hollow wheel body 7. During the self-rotation process of the rotating hollow wheel body 7, the slurry continuously sprays from the outlets of each grouting insertion pipe 8 onto the surfaces on both sides of the roadbed edge, thereby completing the grouting work. By designing this "I"-shaped mixing and grouting integrated device, it can perform grouting spraying along both sides of the water-stable structure layer road, especially for grouting the two side edges of the water-stable structure layer road, which can effectively improve the density and strength of the base side and the joint surface, ensuring the construction quality. And through the arranged telescopic mechanism 3, the overall distance between the two sprayers 6 can be controlled according to the actual width of the road, enabling the device to be adapted to roads with different widths; during the traveling process of the vehicle body 1, by adjusting the length of the telescopic mechanism 3, it can ensure that the slurry can be evenly sprayed onto both sides of the road edge, avoiding uneven grouting or omission. When the grouting work of a section of the road is completed, close the electric valve 5 to stop the transportation of the slurry; then, move the vehicle body 1 to the position of the next section of the road to be grouted as needed, and repeat the above operations until the grouting work of the entire water-stable structure layer is completed;

[0037] Through the above embodiments, the water injection assembly can evenly inject water into the mud powder in each area inside the mixing barrel 2, changing the situation where it is difficult for water to quickly penetrate into the interior of the mud powder under the traditional water addition method, effectively avoiding the layering phenomenon that occurs in the initial stage of mixing the mud powder and water. The uniform water injection creates good conditions for the full mixing of the mud powder and water, helps to form a uniform cement slurry, avoids the situation where the mud powder in some areas is not fully hydrated due to layering, thus ensuring that the quality of the prepared cement meets the standards, providing high-quality raw materials for the subsequent construction of the water-stable layer, cooperating with the mixing assembly to ensure full contact and reaction between the mud powder and water, forming a slurry with uniform texture and stable performance. This high-quality slurry is the basis for ensuring the construction quality of the water-stable layer, greatly shortening the mixing time and improving the mixing efficiency.

[0038] As Figures 3 to 5 shown, the water injection assembly includes two groups of water storage barrels 13. Each group has multiple water storage barrels 13, which are respectively located in the upper and lower layers of the mixing barrel 2. The outer walls of the water storage barrels 13 are all slidably connected to the inner wall of the mixing barrel 2. Hollow pistons 21 are slidably connected inside each water storage barrel 13. On one side of each of the two groups of water storage barrels 13, there is a rotary extrusion and pushing assembly for pushing the water storage barrels 13 out of the mixing barrel 2.

[0039] During operation: When the mud powder is added into the interior of the mixing barrel 2, there will be no mud powder stored at the positions occupied by the two groups of multiple water storage barrels 13 inside the mixing barrel 2. At this time, each water storage barrel 13 is filled with water. Through the rotary extrusion and pushing assembly, all the water storage barrels 13 are simultaneously pushed out of the mixing barrel 2. At this time, due to the water inside the water storage barrel 13 being subjected to the counter-extrusion pressure of the hollow piston 21, under the action of this counter-extrusion pressure, the water will spray out from the side of the water storage barrel 13 close to the interior of the mixing barrel 2, thus forming uniform water columns with a certain pressure. These water columns are evenly dispersed in each area of the upper and lower layers of the mixing barrel 2, can contact the mud powder in the mixing barrel 2 in all directions, ensuring the uniformity of water injection, effectively avoiding the layering phenomenon caused by the difficulty of water quickly penetrating into the interior of the mud powder under the traditional water addition method, and creating good conditions for the subsequent full mixing of the mud powder and water.

[0040] As Figures 3 to 4 shown, one side of each of the multiple hollow pistons 21 is fixedly communicated with a water inlet pipe 11. A plurality of receiving plates 29 are fixedly connected to the side surface of the vehicle body 1, and water tanks 10 are fixedly connected above each receiving plate 29. The end of the water inlet pipe 11 far from the hollow piston 21 is fixedly communicated with the adjacent water tank 10. A water pump 12 is provided outside each water inlet pipe 11.

[0041] During operation: First, turn on each water pump 12. Under the action of the water pump 12, the water stored inside the water tank 10 continuously enters into each water storage bucket 13 along the water inlet pipe 11 until each water storage bucket 13 is filled with water. Subsequently, add the mud powder into the mixing barrel 2. At this time, turn off the water pump 12 to cut off the water connection between the water tank 10 and the water storage bucket 13, and start the rotating extrusion assembly. This assembly pushes each water storage bucket 13 to move outward from the mixing barrel 2. Since the water inlet pipe 11 is in a closed state at this time (due to the water pump 12 being turned off and there are one-way valves and other structures in the water inlet pipe 11 to prevent backflow), the water cannot flow back into the water tank 10 through the water inlet pipe 11. During the process of the water storage bucket 13 moving outward, the water inside is subjected to the reverse extrusion pressure generated by components such as the hollow piston 21, and can only spray out from one end of the water storage bucket 13 close to the inside of the mixing barrel 2, thereby forming horizontal water columns in the mud powder pile, which are evenly distributed in each area of the mixing barrel 2, preparing for the subsequent full mixing of the mud powder and water.

[0042] As Figures 8 to 9 shown, the rotating extrusion assembly includes a motor 17. A cover plate 18 is provided at the top of the mixing barrel 2. The motor 17 is fixedly installed on the top of the cover plate 18. The output shaft of the motor 17 is fixedly connected to a central rotating shaft 15. The central rotating shaft 15 is rotationally connected to the inner wall of the cover plate 18. Two groups of arc-shaped extrusion rods 16 are fixedly connected to the outer wall of the central rotating shaft 15. The number of each group of arc-shaped extrusion rods 16 is the same as the number of water storage buckets 13. Fixing members 14 are fixedly connected to the tops of the water storage buckets 13. The fixing members 14 are slidably connected to the inner wall of the mixing barrel 2. The outer wall of the fixing member 14 is in contact with the outer side of the arc-shaped extrusion rod 16.

[0043] During operation: In the initial state, the outer side of the arc-shaped extrusion rod 16 is in close contact with the outer wall of the fixing member 14. At this time, the water storage bucket 13 is in a preset position inside the mixing barrel 2, waiting for the water injection operation. When it is necessary to inject water after adding the mud powder, start the motor 17. The motor 17 drives the central rotating shaft 15 to rotate. Since the central rotating shaft 15 is fixedly connected to the arc-shaped extrusion rods 16, the rotation of the central rotating shaft 15 will drive multiple arc-shaped extrusion rods 16 to rotate synchronously inside the mixing barrel 2. During the rotation of the multiple arc-shaped extrusion rods 16, their arc-shaped profiles will gradually squeeze the adjacent fixing members 14. Since the fixing members 14 are slidably connected to the inner wall of the mixing barrel 2, after being subjected to the extrusion force of the arc-shaped extrusion rods 16, the fixing members 14 will slide along the inner wall of the mixing barrel 2 and gradually exit the inside of the mixing barrel 2. Driven by the fixing members 14, the water storage bucket 13 will also gradually slide out of the inside of the mixing barrel 2. As the water storage bucket 13 slides out, the reverse extrusion pressure on the internal hollow piston 21 increases, prompting the water to spray out from one end of the water storage bucket 13 close to the inside of the mixing barrel 2, forming a uniform water column and being initially mixed with the mud powder.

[0044] As Figures 5 to 7As shown in the figure, a blocking plate 19 is provided at one end of the water storage bucket 13. The outer wall of the blocking plate 19 fits with the inner wall of the water storage bucket 13. A side connection plate 20 is fixedly connected to one side of the blocking plate 19. A plurality of connecting rods 23 are connected to both sides of the side connection plate 20. Hollow columns 22 are fixedly connected to both sides of the water storage bucket 13. The hollow columns 22 are all slidably connected to the inner wall of the mixing bucket 2. Movable blocks 24 are slidably connected to the inner walls of the hollow columns 22. One side of the movable block 24 is fixedly connected to one end of the connecting rod 23.

[0045] During operation: In the stage of adding mud powder, the blocking plate 19 blocks one end of the water storage bucket 13 close to the inside of the mixing bucket 2, effectively preventing the mud powder from entering the inner cavity of the water storage bucket 13, ensuring the purity of the water inside the water storage bucket 13 and the smoothness of the subsequent water injection process; when the water storage bucket 13 slides out of the mixing bucket 2 under the action of the rotating extrusion assembly, due to the water inside the water storage bucket 13 being subjected to an anti-extrusion force, a large impact force is generated. Under the action of this water impact force, the blocking plate 19 and the side connection plate 20 will move to one side, thereby driving the movable block 24 to slide inside the hollow column 22; at this time, the outlet end of the water storage bucket 13 is briefly opened, and the water originally blocked by the blocking plate 19 is gradually squeezed out under the pressure and occupies the original position of the water storage bucket 13, thus forming a water column with the same shape as the water storage bucket 13 and evenly spraying it on the mud powder pile to achieve uniform water injection.

[0046] As Figures 6 to 7 shown in the figure, springs 25 are provided inside the hollow columns 22. One end of the spring 25 is fixedly connected to the inner wall surface of the hollow column 22, and the other end of the spring 25 is fixedly connected to one end of the movable block 24. A limiting component is provided above the blocking plate 19.

[0047] During operation: During the water injection process, when the water storage bucket 13 slides out of the mixing bucket 2 under the action of the rotating extrusion assembly, due to the reverse extrusion pressure of the water inside the water storage bucket 13, the blocking plate 19 and the side connection plate 20 will move to one side, thereby driving the movable block 24 to slide inside the hollow column 22. This process will pull the spring 25 and cause it to deform; when the water storage bucket 13 moves to the maximum position outside the mixing bucket 2, at this time, the water in the inner cavity of the water storage bucket 13 has been completely squeezed out, and the mixing assembly will then start to rotate and stir inside the mixing bucket 2 to evenly mix the mud powder and water to form slurry; after the water storage bucket 13 completes the movement, under the elastic restoring force of the spring 25, the blocking plate 19 will reset and re-block the outlet end of the water storage bucket 13; when the slurry inside the mixing bucket 2 is discharged and used up, the blocking plate 19 is restricted by the limiting assembly so that it no longer moves after blocking the outlet of the water storage bucket 13. At this time, the water pump 12 is turned on, and the water inside the water tank 10 will enter the inner cavity of the water storage bucket 13 along the water inlet pipe 11. As the water is continuously injected, the inner cavity of the water storage bucket 13 will be gradually expanded, and then the water storage bucket 13 will completely enter the mixing bucket 2 again to prepare for the next water injection operation.

[0048] As Figures 6 to 7 shown, the limiting assembly includes a plurality of fixing plates 26, the fixing plates 26 are respectively fixedly connected to one side of the fixing member 14, and telescopic rods 27 are fixedly connected to the inner walls of the fixing plates 26, and a resisting block 28 is fixedly connected to the bottom of each telescopic rod 27.

[0049] During operation: By controlling the telescopic rod 27, the resisting block 28 is driven to descend. After the resisting block 28 descends, it will resist the outer wall of the blocking plate 19. When the water storage bucket 13 is refilled with water, due to the change in the pressure inside the inner cavity of the water storage bucket 13 caused by the entry of water, it may drive the blocking plate 19 to have a tendency to move; but under the blocking of the resisting block 28, the blocking plate 19 cannot move, thereby ensuring that the water storage bucket 13 can complete the water injection process normally and stably, ensuring that water can smoothly enter the inner cavity of the water storage bucket 13, and there will be no abnormal water injection situation caused by the accidental movement of the blocking plate 19 during the water injection process; after the water injection is completed, then control the telescopic rod 27 to contract, so that the resisting block 28 rises to release the limit on the blocking plate 19, so that the water storage bucket 13 can perform the water injection and spraying operation under the action of the rotating extrusion assembly subsequently.

[0050] As Figure 8 and Figure 10 shown, the mixing assembly includes a plurality of connecting blocks 30, the connecting blocks 30 are respectively fixedly connected to one side of the arc-shaped extrusion rod 16, the inner walls of the connecting blocks 30 are all rotatably connected with rotating rods 31, and a plurality of stirring mechanisms 32 are fixedly connected to the outer walls of the rotating rods 31. An autorotation assembly for driving the rotating rod 31 to rotate is arranged above the rotating rod 31.

[0051] During operation: When the motor 17 drives the arc-shaped extrusion rod 16 to rotate through the central rotating shaft 15, it will first cause the water storage bucket 13 to move outward from the mixing bucket 2 for water injection. When the water column is formed, the arc-shaped extrusion rod 16 continues to rotate. At this time, due to the action of the self-rotation assembly, the rotating rod 31 begins to rotate, thereby driving the stirring mechanism 32 to rotate. At the same time, the revolution of the arc-shaped extrusion rod 16 also drives the connecting block 30 and the rotating rod 31 as a whole to revolve, so that the stirring mechanism 32 passes through each water column during the revolution. Under the combined action of the revolution and self-rotation of the stirring mechanism 32, the mud powder and water are stirred in all directions and at multiple angles, so that the mud powder and water are fully and evenly mixed, quickly forming high-quality slurry, and improving the mixing efficiency and effect.

[0052] As Figures 10 to 11 shown, the self-rotation assembly includes a circular chute seat 34. The circular chute seat 34 is fixedly connected to the top of the cover plate 18. Inner sliders 33 are fixedly connected to the outer walls of the rotating rods 31. The inner sliders 33 are slidably connected to and adapted to the circular chute seat 34. The tops of the rotating rods 31 are fixedly connected with gears 35. The teeth of the gears 35 are engaged with an external gear 36. The external gear 36 is fixedly connected to the top of the cover plate 18.

[0053] During operation: When the motor 17 is started and drives the arc-shaped extrusion rod 16 to rotate through the central rotating shaft 15, the arc-shaped extrusion rod 16 drives the connecting block 30 and the rotating rod 31 as a whole to revolve. During the revolution, due to the sliding of the inner slider 33 in the circular chute seat 34, the revolution of the rotating rod 31 can be carried out stably. At the same time, because the gear 35 at the top of the rotating rod 31 is engaged with the external gear 36 fixed to the top of the cover plate 18, when the rotating rod 31 revolves, the gear 35 will roll along the teeth of the external gear 36. Since the external gear 36 is fixed, this rolling effect will be converted into the self-rotation of the gear 35, thereby driving the rotating rod 31 to rotate. When the rotating rod 31 rotates, the multiple stirring mechanisms 32 fixedly connected to its outer wall also rotate accordingly. Under the combined action of the revolution and self-rotation of the stirring mechanism 32, the mud powder and water in the mixing bucket 2 are fully stirred and mixed.

[0054] As Figure 1 shown, a pouring bin 9 is arranged at the top of the mixing bucket 2. The pouring bin 9 is fixedly communicated with the inner wall of the cover plate 18.

[0055] During operation: Through the arranged pouring bin 9, the mud powder can be added into the mixing bucket 2 through the pouring bin 9, thus completing the feeding process.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
