Description

Изобретение относитс  к области строительства газопроводов в услови х вечномерзлых грунтов Крайнего Севера, где необходима теплоизол ци  трубопроводов. Известен способ строительства газопровода в мерзлых грунтах при совместной прокладке его с ингибиторапроводом. Прокладка промысловых трубопроводов с теплым газом в зонах вечномерзлых грунтов на Севере способствует распространению тепла вокруг трубы и по влению .процессов протаивани , просащки и вьтучввани  грунтов, что способствует (повреждению трубопроводов. При прокладке газопроводов и ингибиторопроводов в данных случа х необходимо создание дл  них теплозащиты из минеральной ваты, стекловолокна, пенопласта и других материалов, преп тствующих распространению тепла в грунт и охлаждению транспортируемого продукта в трубопроводе. Прокладка обеих труб выполн етс  в общей или индивидуальной защитной оболочке, состо щей из теплового, гидрозащитного и покровного слоев. , ,. ,. . Цель предлагаемого изобретени  - сокращение расхода металла и термоизол ционных материалов., , Дл  этого по 1предлатаемому способу ингнбиторопровод размещают внутри газопровода. По предлагаемому способу монтаж трубопроводов на промысле выполн ют следующим образом. Секции труб газопровода с изол ционным покрытием и ингибиторопровода без изол ции доставл ют на трассу и раскладывают вдоль транщеи. Затем первую секцию ингибиторопровода вставл ют заглущенвым концом и проталкивают трактором в газопровод, после чего противоположные концы труб сваривают поочередно (сначала внутренний, а затем внешний трубопроводы) с последующими секци ми . Укладка ингибиторопровода возможна также и путем проталкивани  его в газопровод с постепенным его наращиванием. Монтаж газопровода на углах поворота производ т после прокладки в них ингибиторопроводов . Предмет изобретени  Способ строительства газопровода в мерзлых грунтах при совместной прокладке его с ингибиторапроводом, отличающийс  тем, что, с целью сокращени  расхода металла и теплоизол ционных материалов, ингибиторопровод размещают внутри газопровода.The invention relates to the field of construction of gas pipelines in the permafrost conditions of the Far North, where heat insulation of pipelines is necessary. There is a method of building a gas pipeline in frozen soils with a joint laying it with the inhibitor line. Laying field pipelines with warm gas in permafrost zones in the North contributes to the spread of heat around the pipe and the occurrence of the thawing process, throughput and injection of soil, which contributes to (damage to pipelines. When laying gas pipelines and inhibitor lines in these cases, heat protection should be created for them from mineral wool, fiberglass, foam, and other materials that prevent the spread of heat into the soil and cooling of the transported product in the pipeline. and both pipes are made in a common or individual protective sheath, consisting of thermal, hydro-protective and coating layers.,.,.. The aim of the proposed invention is to reduce the consumption of metal and thermal insulation materials. For this, according to the proposed method, the ingbitbit pipeline is placed inside According to the proposed method, the installation of pipelines in the field is carried out as follows: Sections of pipelines of the pipeline with an insulating coating and an inhibitor line without insulation are delivered to the track and laid out along the trench. Then, the first section of the inhibitor line is inserted with a gagged end and pushed by the tractor into the gas pipeline, after which the opposite ends of the pipes are welded alternately (first the inner and then the outer piping) with subsequent sections. The laying of the inhibitor line is also possible by pushing it into the gas pipeline with its gradual buildup. The gas pipeline was installed at the angles of rotation after the inhibitor lines were laid. The subject of the invention. A method of constructing a gas pipeline in frozen soils when it is jointly laid with an inhibitor line, characterized in that, in order to reduce the consumption of metal and thermal insulation materials, the inhibitor line is placed inside the gas pipeline.
