Description

TECHNICAL FIELD

[0001] The utility model relates to road construction technical field, concretely is a kind of height-adjustable roadbed compaction device. BACKGROUND

[0002] Nowadays, most of the highways are asphalt pavement. During the construction of the highway, the roadbed usually needs to be compacted, and then the asphalt is paved on top. The purpose of compaction is to prevent the roadbed from sinking and causing the problem of road surface cracking.

[0003] For example, the patent with the announcement number CN221118156U authorized by the state discloses a roadbed compaction device, which comprises a road roller and a water pump. One end of the road roller is connected with a connecting block, and the surface of the connecting block is rotatably connected with a mounting frame. The mounting frame is rotatably connected with a connecting shaft in the middle. The connecting shaft is rotatably connected with a soil compaction roller in the middle. The surface of the soil compaction roller is provided with a placing groove. A gravity rod is installed inside the placing groove. A water pump is installed inside the upper part of the water supply tank. One end of the water pump is connected with a water guide pipe. The other end of the water pump is connected with a drain pipe. The end of the drain pipe is connected with a water collecting plate fixed above the mounting frame. The roadbed compaction device can sequentially place gravity rods into the placing groove on the surface of the soil compaction roller, which can conveniently adjust the gravity of the soil compaction roller. The pressure roller can adapt to different stress roadbed environments. At the same time, the use of the rotating positioning plate facilitates the limiting of the gravity rod.

[0004] However, the above-mentioned roadbed compaction device cannot adjust the height of the soil compaction roller according to different terrain conditions and construction requirements during the compaction process. For example, in low-lying areas, the soil compaction roller cannot be fully pressed down. In protruding areas, the soil compaction roller will be excessively pressed, causing uneven compaction and affecting the overall compaction quality and stability of the roadbed.
