Abstract
Description
Изобретение относится к строительству и может быть применено при прокладке нефтепроводов, газопроводов и воды в труднодоступных районах, требующих усиленной гидроизоляции труб.The invention relates to the construction and can be applied when laying oil pipelines, gas pipelines and water in remote areas that require enhanced waterproofing of pipes.
Известно устройство для нанесения защитной эластичной оболочки на трубу /а.с. SU №1676821/. К недостаткам устройства возможно отнести проблематичность его использования в полевых условиях и трудоемкость в целом.A device for applying a protective elastic sheath on a pipe is known. SU # 1676821 /. The disadvantages of the device may include the difficulty of its use in the field and the complexity of the whole.
Поставленная цель достигается тем, что способ нанесения защитной эластичной оболочки на трубу в полевых условиях содержит размещение в полом цилиндрическом корпусе, на внутренней поверхности которого выполнены каналы из сообщающихся между собой кольцевых пазов, соединенных с системой вакуумирования, с прижатием к внутренней поверхности цилиндрического корпуса защитной оболочки с последующем размещением в нем трубы и снятием вакуумирования. Заявленное изобретение отличается тем, что прижатие защитной оболочки к внутренней поверхности цилиндрического корпуса обеспечивается созданием в оболочке давления выше атмосферного, а перед размещением трубы в корпусе на него и трубу устанавливают инвентарные полозья.This goal is achieved by the fact that the method of applying a protective elastic sheath on a pipe in field conditions contains accommodation in a hollow cylindrical body, on the inner surface of which channels are made of interconnecting annular grooves connected to the vacuum system, pressing the protective sheath to the inner surface of the cylindrical body with the subsequent placement of the pipe in it and the removal of the vacuum. The claimed invention is characterized in that the pressure of the protective shell against the inner surface of the cylindrical body is ensured by creating above-atmospheric pressure in the shell, and before placing the pipe in the body, inventory rails are installed on it and the pipe.
В полый цилиндрический корпус (в специальную оснастку, представляющую собой трубу) внутренняя поверхность которого снабжена системой каналов из сообщающихся между собой кольцевых пазов, соединенных с системой вакуумирования, вводят эластичную оболочку давлением выше атмосферного и после охватывания оболочкой системы пазов оснастки, т.е. как бы прилипания к ее внутренней поверхности, удерживают оболочку в таком положении переходя на систему вакуумирования и заводят в оболочку трубу, вакуум снимают, что обеспечивает облегание оболочкой наружной поверхности трубы. После чего, с помощью инвентарных полозьев, оснастку, если произошло соединение с предыдущей трубой, извлекают и процесс возобновляется уже с другой трубой.In the hollow cylindrical body (in a special tooling, which is a pipe) the inner surface of which is provided with a system of channels from interconnecting annular grooves connected to the vacuum system, the elastic sheath is introduced with a pressure above atmospheric and, after embracing the system of equipment grooves, as if sticking to its inner surface, holding the casing in such a position, switching to a vacuum system and winding the pipe into the casing, removing the vacuum, which ensures that the casing of the outer surface of the pipe fits. After that, with the help of inventory runners, a snap-in, if a connection with the previous pipe has occurred, is removed and the process is resumed with another pipe.
Процесс поясняется чертежом в момент завершения операции по нанесению гидроизоляции. Предыдущая труба 5 стыкуется с новой трубой 3 и на нее устанавливается полый цилиндрический корпус 1 (оснастка, представляющая собой трубу), внутренняя поверхность которого снабжена системой каналов из сообщающихся между собой кольцевых пазов /не показано/, на внутреннею поверхность посредством повышенного давления наносится эластичная оболочка 2, которая фиксируется включением вакуумнасоса, отключение которого обеспечивает облегание оболочкой 2 трубы 3. После чего корпус 1 (оснастку) извлекают с помощью установленных на него и на трубу 3 полозьев 4.The process is illustrated in the drawing at the time of completion of the operation of applying waterproofing. The previous pipe 5 is joined with a new pipe 3 and a hollow cylindrical body 1 is installed on it (the equipment is a pipe), the inner surface of which is equipped with a channel system of annular grooves interconnected / not shown /, an elastic shell is applied to the inner surface by means of increased pressure 2, which is fixed by turning on the vacuum pump, the shutdown of which provides for fitting the pipe 2 with the shell 2. Then the body 1 (accessories) is removed with the help of the pipes 3 installed on it and the pipe olozev 4.
