Quick dismounting method for jacket grouting pipeline
The invention discloses a jacket grouting pipeline quick dismantling method which comprises the following steps that S1, a grouting pipeline is arranged to be of an up-down sectional structure and connected through a quick connector, and the connecting point of the two sections of grouting pipeline is arranged underwater; s2, the lower section of the grouting pipeline is fixedly connected to a jacket and is arranged to be of a permanent structure, and the upper section of the grouting pipeline is fixed on the water surface in a welding mode and temporarily fixed under the water surface in the mode that a rigging penetrates through a butt joint hole; s3, after grouting is completed, fixed connection of the upper section of the grouting pipeline on the water surface is removed, a diver enters water to disconnect the quick connector, and separation of the two sections of the grouting pipeline is achieved; and S4, the rigging is pulled out, and rapid dismounting of temporary fixation of the lower section of the grouting pipeline is completed. By the adoption of the pipeline quick dismantling structure and technology, the traditional jacket construction operation process can be optimized, floating crane operation ships are saved, the ocean platform installation operation efficiency is improved, and the ocean platform construction cost is effectively saved.
本发明公开了一种导管架灌浆管线快速拆除方法，包括以下步骤：S1、将灌浆管线设置为上下分段式结构且通过快速接头连接，两段所述灌浆管线的连接点设置于水下；S2、下段所述灌浆管线固定连接于导管架且设置为永久结构，上段所述灌浆管线在水面上采用焊接固定，在水面下采用索具穿对接孔的方式进行临时固定；S3、当灌浆完毕后，解除上段所述灌浆管线在水面上的固定连接，潜水员下水断开所述快速接头，实现两段所述灌浆管线的分离；S4、将所述索具抽出，完成下段所述灌浆管线临时固定的快速拆除。本发明采用管线快速拆除结构和技术，可优化传统的导管架施工作业流程，节约浮吊作业船舶，提升海洋平台安装作业效率，有效节约海洋平台建设成本。
