Drainage method for forming pipeline section of subsea drainage pipe
The invention discloses a launching method for forming a pipeline section of a sea drainage pipeline. The launching method comprises the following steps that firstly, a movable saddle and a pipeline support are placed on an assembly station of a pipeline assembly platform; secondly, the multiple sections of pipelines are hoisted to an assembling station to be assembled into pipeline sections; thirdly, a plurality of movable saddles and the pipeline sections are moved forwards to a welding station through a plurality of pushing devices to be welded; fourthly, after welding of the pipeline sections is completed, the multiple movable saddles and the pipeline sections are moved forwards to an anti-corrosion station through the multiple pushing devices to be subjected to anti-corrosion treatment; and 5, a plurality of movable saddles are moved forwards to a gliding trolley located on the top of the launching slideway beam through a plurality of pushing devices, then a plurality of winches are controlled to lower the movable saddles located on the gliding trolley, and the pipeline sections with the two ends blocked naturally float after being submerged into water. And finally, a plurality of gliding trolleys are pulled to the top of the launching slideway beam through a plurality of winches to be fixed. The pipeline can stably enter water.
本发明公开了一种形成排海管的管道节段的下水方法，包括以下步骤：步骤一，在管道拼接平台的拼装工位放置移动鞍座和管道支座；步骤二，将多节管道吊至拼装工位拼装成管道节段；步骤三，通过数个顶推装置将数个移动鞍座连同管道节段向前移动至焊接工位进行焊接；步骤四，管道节段焊接完成后，通过数个顶推装置将数个移动鞍座连同管道节段向前移动至防腐工位进行防腐处理；步骤五，通过数个顶推装置将数个移动鞍座向前移动至位于下水滑道梁顶部的下滑小车上，然后控制数个卷扬机将位于数个下滑小车上的移动鞍座下放，两端封堵的管道节段在没入水中后自然上浮，最后通过数个卷扬机将数个下滑小车牵引至下水滑道梁的顶部固定。本发明使管道平稳下水。
