Способ прокладки трубопроводов или проходов, в котором первый гибкий трубчатый элемент вывертывается, образуя поверхность трубопровода или прохода, подлежащего прокладке, и к концу тягового конца первой гибкой трубы присоединяется сложенная обсадочная труба так, что она втягивается внутрь трубопровода или прохода посредством операции вывертывания, при этом используется подогретая жидкость для вывертывания, так что, когда термопластиковая труба полностью находится внутри трубопровода или прохода, она окружается подогретой водой для размягчения, вследствие чего размягченная термопластиковая труба расширяется под действием давления жидкости вплоть до образования поверхности трубопровода или прохода, где она может или вынуждена затвердеть по месту.A method of laying pipelines or passages in which the first flexible tubular element is twisted to form the surface of the pipeline or passage to be laid, and the folded casing is attached to the end of the trailing end of the first flexible pipe so that it is drawn into the pipeline or passage through a wrenching operation, while a heated wrenching fluid is used, so that when the thermoplastic pipe is completely inside the pipeline or passageway, it is surrounded by heated water for softening, resulting in a softened thermoplastic pipe expands under the action of fluid pressure until the formation of the surface of the pipeline or passage, where it can or is forced to harden in place.
