Description

Technical Field

[0001] The utility model relates to the technical field of pipeline backfilling, in particular to a pipeline groove compacting device. Background Art

[0002] In pipeline projects, trenches must be excavated first to lay pipelines. After the pipelines are installed, they need to be backfilled and compacted in layers to achieve sufficient density. If it is not dense enough, after the pipelines are installed and backfilled to level the road, it is easy for natural settlement to cause a significant height difference at the bottom of the trench. The settlement of the bottom of the trench causes deformation of the laid pipelines, which is one of the main factors causing problems such as cracks, breakages, and leaks in the pipelines.

[0003] When compacting the pipe around the pipe, the pipe joint is convex, making the pipe as a whole discontinuous. The existing compacting equipment cannot compact the pipe joint effectively, causing the pipe joint to suddenly become loose, which in turn makes it easy to leak, reduces the protection effect of the pipe, and affects the service life of the pipe.
