step S10: a plurality of compensation points for compensating axial and/or radial displacements of the pipeline are arranged, the positions of the compensation points being fixed, each compensation point having a pipeline mounting structure.
The compensation points can compensate displacement caused by deformation of the pipeline, damage to the pipeline due to deformation is avoided, and the compensation amount of the compensation points is limited, so that the reason that the pipeline deforms needs to be judged in time; the deformation of the pipeline caused by settling in this embodiment is mainly directed to horizontally installed pipelines.
Step S20: the axial displacement of the pipeline at the compensation point is obtained, as well as the radial offset.
The amount of axial displacement in this embodiment refers to the amount of deformation occurring in the length direction of the pipeline, and the amount of radial displacement refers to the amount of rotation occurring in the vertical direction of the pipeline.
Step S30: and judging whether the pipeline deforms due to settlement or not according to the axial displacement and the radial offset.
In this embodiment, after the pipeline deforms due to temperature, the displacement is usually in the axial direction, so that only the axial displacement can be detected, and the detection value of the radial offset is zero; when the axial displacement and the radial offset are detected simultaneously, the deformation of the pipeline can be judged to be caused by geological settlement.
