Изобретение относится к области нанесения покрытий на внутренние поверхности конструкций и может быть использовано при восстановлении изношенных поверхностей труб. Во внутренний объем протяжной конструкции вводят герметизирующий элемент каплевидной формы с хвостовиком, содержащий основу из волокнистого материала и водонепроницаемый слой из пластичного материала толщиной не менее 1,5 мм, перемещают его в потоке транспортирующей среды к месту нанесения покрытий и прижимают. Способ прост и экономичен, позволяет наносить покрытия на поврежденные поверхности при восстановлении подземных трубопроводов без вскрытия их на больших участках.The invention relates to the field of coating on the internal surfaces of structures and can be used to restore worn pipe surfaces. A drop-shaped sealing element with a shank containing a base of fibrous material and a waterproof layer of plastic material with a thickness of at least 1.5 mm is introduced into the inner volume of the long-drawn structure, it is moved in the flow of the transporting medium to the coating site and pressed. The method is simple and economical, allows you to apply coating to damaged surfaces during the restoration of underground pipelines without opening them in large areas.
