[0002] In water conservancy projects, pipeline transportation plays a vital role. In order to ensure the safety and stability of the pipeline during transportation, the pipeline needs to be limited. At present, the common pipeline limiting structure mainly uses two limiting columns to fix the two ends of the inner wall of the pipeline. However, this limiting structure has certain limitations in practical applications.

[0003] The traditional pipeline limiting structure requires that the limiting columns be placed at the two ends of the pipeline inner wall with the farthest diameter to ensure that the pipeline will not shift during transportation. However, since the inner wall diameters of pipelines of different diameters are of different lengths, the limiting columns need to always fit at the two ends of the pipeline inner wall with the longest diameters. This leads to a problem, that is, when the limiting columns are not placed at the farthest ends, there is a movable gap between the pipeline and the limiting columns, so that the pipeline is still in an unstable support state.
