Finding the Displacement of Elastically Bent Pipeline Disposed on Roller Supports Under the Action of the Axial Shear Force
[摘要] The authors of this article have developed a spatial position determination method of a real steel pipeline free segment located above the ground surface during pipeline pullback using a pipeline pusher for the horizontal directional drilling technology. Values of elastically bent pipeline displacement were found in different points of the pipeline profile with the aim of defining the admissible values of the shear force applied to the pipeline by additional equipment during the pipeline pullback process. The developed methods allow finding the points of the curved pipeline profile in which it is necessary to place additional fixing connections above the pipeline, as this will expand the range of the shear force applied to the pipeline.
