The invention discloses a method for dragging a discarded jacket ashore. The method comprises the following steps: installing a winch and a sliding assisting air bag on a slope wharf, and dragging the discarded jacket floating on the sea surface to the slope wharf by virtue of the pulling force of the winch and the effect of reducing friction force of the sliding assisting air bag. Compared with a traditional method adopting large floating crane hoisting, the method of the invention has the advantages that a large number of floating crane resources are saved, the cost expenditure is reduced, the influence of difficulty in scheduling due to scarcity of large floating crane resources is avoided, and the project construction period can be effectively shortened.
本发明公开了一种用于弃置导管架拖拉上岸的方法,通过在斜坡面码头上安装绞车和助滑气囊,借助绞车拉力以及助滑气囊减小摩擦力的作用,将漂浮在海面上的弃置导管架,拖拉到斜坡面码头上,相对于传统采用大型浮吊吊装的方法,节约了大量的浮吊资源,减少了成本支出,且不受大型浮吊资源稀少档期调配困难的影响,可有效缩短项目工期。
