Abstract
1. Способ демонтажа магистральных трубопроводов, заключающийся во вскрытии сухопутного участка демонтируемого трубопровода, разрезке трубопровода в урезной его части, установке на суше лебедки с блоком, разработке двух приямков ниже нижней образующей трубопровода, для последующего продевания через них металлических полотенец, приваривании к торцу урезной части демонтируемой трубы оголовка с блоком, отличающийся тем, что на берегу лебедку с блоком и якорный трос от лебедки крепят к двум разным анкерам, к телу трубы, рядом с оголовком, приваривают металлическую площадку, на металлическую площадку устанавливают площадочный вибратор и после его установки натягивают тяговый трос по оси трубопровода в сторону берега, до достижения рабочей величины, после достижения рабочей величины натяжения тягового троса, включают площадочный вибратор и начинают вертикальный подъем трубы с помощью двух кранов трубоукладчиков, при этом, после извлечения зацепленного участка трубопровода, краны трубоукладчики перемещают дальше от оголовка трубы поочередно.2. Способ по п.1, отличающийся тем, что на берегу лебедку с блоком и якорный трос от лебедки крепят к одному анкеру.1. The method of dismantling the main pipelines, which consists in opening the land section of the dismantled pipeline, cutting the pipeline in its lower part, installing winch with a block on land, developing two pits below the lower generatrix of the pipeline, for subsequent threading through them metal towels, welding to the end of the cutting part a dismantled head pipe with a block, characterized in that on the shore a winch with a block and an anchor cable from the winch are attached to two different anchors, to the pipe body, next to the head, etc. the metal platform is varied, a platform vibrator is installed on the metal platform and, after its installation, the traction cable is pulled along the axis of the pipeline towards the shore, until the working value is reached, after the traction cable tension is reached, the platform vibrator is turned on and the pipe is lifted vertically using two pipe-laying cranes Moreover, after removing the hooked section of the pipeline, the pipe-laying cranes move further from the pipe head alternately. 2. The method according to claim 1, characterized in that on the shore a winch with a block and an anchor cable from the winch are attached to one anchor.
