[0040] In one embodiment of this utility model, the roadbed construction and paving device with the above-described structure can be used to dehumidify the roadbed water layer, lay road materials, level and compact the roadbed when the road surface is paved in a humid and hot environment and there is water accumulation in the roadbed.

[0041] First, the lifting cylinder 34 is controlled by the controller 7 to extend and retract, which in turn drives the water suction bucket 32 ​​to rise and fall, thereby adjusting the height of the water suction bucket 32. The change in the height of the water suction bucket 32 ​​allows the water-absorbing sponge pad 37 to come into contact with the roadbed surface with water accumulation. During this process, the water on the road surface will seep through the sponge pad 37 to the top of the water suction bucket 32. At this time, the air pump 36 is controlled by the controller 7 to extract the air inside the water collection tank 31, reducing its internal pressure. At this time, the water in the water-absorbing sponge pad 37 will enter the water collection tank 31 through the connecting pipe 33, realizing the removal and collection of water accumulation on the roadbed surface in a humid and hot environment.

[0042] In addition, the raw materials for road paving are first placed in the paving hopper 41. Initially, the controller 7 controls the hydraulic cylinder 42 to work and can extend and retract. When the hydraulic cylinder 42 retracts, the paving hopper 41 rotates to the right with the axis of the lower connecting shaft 46 as the center. At this time, the discharge port 45 tilts upward to stop the material discharge. Conversely, the discharge port 45 on the paving hopper 41 faces downward, which facilitates the discharge of raw materials in the paving hopper 41 and carries out the supply operation of raw materials in the roadbed and road surface paving.

[0043] As the device moves to the left, the arc-shaped scraper 52 will come into contact with the material on the road surface, thereby achieving the scraping operation of the road paving material. The arc-shaped structure of the arc-shaped scraper 52 facilitates the distribution of the material concentrated in the middle to both sides. During this process, the electric telescopic rod 53 can be raised and lowered by the controller 7, thereby adjusting the height of the arc-shaped scraper 52 and thus adjusting the approximate thickness of the material during the roadbed and road surface paving process. Finally, as the device moves, the paved road surface is compacted by the compaction roller 62 and the roller group 2 moving together.

[0044] It is worth noting that the controller 7 uses existing technology to control the operation of the lifting cylinder 34, the air pump 36, the hydraulic cylinder 42 and the electric telescopic rod 53. The controller 7 is equipped with control buttons that correspond one-to-one with the lifting cylinder 34, the air pump 36, the hydraulic cylinder 42 and the electric telescopic rod 53.

[0045] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
