Description

Technical Field

[0001] The utility model belongs to the technical field of dam surface rolling construction devices, and in particular relates to a dam surface rolling device for a gravel filling dam. Background Art

[0002] For the construction of gravel dam slope concrete panels, the compaction and flatness of the slope are important links related to the quality of the panels and the construction consumption, and are also the key to the progress and cost of the dam panel concrete construction. Before the panel construction, the slope is rolled. At present, the existing method generally adopts manual cooperation with excavators with rolling devices, that is, after the dam body is repaired, the dam slope is rolled before the concrete panel construction. Before rolling, the slope is first sprinkled with water to moisten it. After the wetting is completed, the excavator with a rolling device stands on the slope to roll and compact the trimmed slope. The compaction index meets the design requirements, and the edges and corners of the slope after compaction are supplemented by manual trimming. The disadvantage of this method is that the slope sprinkling and slope rolling are carried out step by step, and the amount of additional slope rolling is large, and the construction period is difficult to guarantee, which will increase the project cost. At the same time, this construction method has slow construction progress and low efficiency. Utility Model Content
