Description

Technical Field

[0001] The utility model relates to the technical field of filling construction equipment, and more specifically, to a dam filling compaction device. Background Art

[0002] The basic procedures for building a dam include: 1. Interception: dig one or several tunnels or open channels in the natural river channel, and then intercept the river channel so that the water flows downstream along the diversion tunnel or diversion open channel; 2. Excavation of foundation pit: Dams can only be built on stable geological structures, so the sediments on the river channel must be excavated, and the dam shoulders (like door frames) must be excavated on both sides until the bedrock layer is exposed; 3. Filling the dam body: fill the dam body according to the type of dam (concrete dam, rockfill dam, etc.) until the cap is capped; 4. Water storage acceptance: All dams must pass the acceptance organized by the relevant departments before they can store water. It is illegal to store water without authorization; 5. Dam registration: All dams must be registered with the National Dam Center, and dams that fail to register shall not be operated. Among the above basic procedures, the most critical is filling the dam, which is the key to ensuring the quality of the project.

[0003] The compaction of the dam body is a key process in dam construction. A compaction device is usually used to compact the dam body. The compaction device includes a compaction roller and a compactor body that drags the compaction roller forward. During the compaction operation, soil, asphalt and other materials will adhere to the surface of the compaction roller. To ensure the flattening effect, the material on the surface of the compaction roller needs to be removed in time. In the prior art, a scraper that can scrape the surface of the compaction roller during the rolling process is usually provided on one side of the compaction roller. Although the scraper can scrape the surface of the compaction roller, during actual use, more and more materials adhere to the scraper, and it is not easy to fall off automatically during the compaction operation. Therefore, the compaction operation needs to be suspended, and the materials adhered to the scraper need to be cleaned manually, which leads to the interruption of the construction operation, prolonging the construction period and reducing the construction efficiency.
