Abstract

Трубное соединение для соединения подземных труб или трубчатых оболочек друг с другом, которое обеспечивает достаточную гидроизоляцию, в котором уменьшены до минимума выступание водопоглощающего набухающего материала внутрь трубы и смятие конца трубы при использовании в течение длительного периода времени и которое может быть легко изготовлено. Трубное соединение (1) включает в себя уплотнительный материал, прикрепленный с образованием единого целого к внутренней периферийной поверхности, по существу, круглого трубчатого корпусного элемента (11) трубного соединения таким образом, что он обращен в наружной периферийной поверхности соединяемых друг с другом труб. Уплотнительный материал образован первым уплотнительным материалом (12), расположенным по винтовой линии с предварительно заданным шагом, и вторым уплотнительным материалом (13), расположенным таким образом, чтобы образовать перекрытие между соседними участками первого уплотнительного материала. По меньшей мере один из первого уплотнительного материала (12) или второго уплотнительного материала (13) состоит из водопоглощающего набухающего материала.Pipe connection for connecting underground pipes or tubular shells with each other, which provides sufficient waterproofing, which reduces to a minimum the protrusion of water-absorbing swelling material into the pipe and wrinkling the pipe end when used for a long period of time and which can be easily manufactured. Pipe connection (1) includes a sealing material attached with the formation of a single whole to the inner peripheral surface of the essentially circular tubular body element (11) of the pipe joint in such a way that it faces in the outer peripheral surface of the pipes connected to each other. The sealing material is formed by a first sealing material (12) located along a helical line with a predetermined pitch, and a second sealing material (13) arranged in such a way as to form an overlap between adjacent sections of the first sealing material. At least one of the first sealing material (12) or the second sealing material (13) consists of a water-absorbing swelling material.
