Interaction Between the Pipeline and Additional Equipment for Trenchless Technologies

[摘要] In this article the authors defined the limits of applicability of the pipeline pusher as additional equipment for pipeline construction when using trenchless methods. In this case, the pushing force is applied to the free end of the pipeline section located on the day surface. The authors obtained analytical dependences for determining the stress-strain state of the pushed pipeline when using the pusher in a particular case. In addition, they identified values of axial pushing force that are considered dangerous, because they can cause pipeline dropping down from the roller supports during pipeline pullback.
