Description

Technical Field

[0001] The utility model belongs to the technical field of compaction devices, and in particular relates to a pipeline trench backfill compaction device. Background Art

[0002] Trench backfill refers to the construction process of filling the trench after excavation and laying of pipelines. After backfilling, the soil needs to be compacted with compaction equipment to increase the density of the backfill material, reduce the void ratio, and prevent foundation settlement caused by water accumulation, thereby extending the service life of the pipeline and its connecting facilities. Most of the current compaction equipment is large-sized machinery. When personnel perform backfill construction in some narrow sections or narrow alleys, the compaction equipment cannot enter the operation due to its size. Personnel are required to use tools such as compaction hammers to perform compaction operations. Compacting is not only laborious, but also relatively inefficient. Utility Model Content
