摘要
通过对海底管道后挖沟作业过程的深入剖析,总结出锚机与后挖沟机相互协调的指挥方法,阐明了驳船绞锚的操作要领和注意事项。针对不同的地质条件和设计要求,提出合理高效的绞锚方式,从而避免海底管道后挖沟过程中后挖沟机对已铺设管道的破坏,并保证海底管道后挖沟的沟形和速度。
Operation process of submarine pipeline post trenching is deeply analyzed in this paper. The command method of the anchor windlass and post trencher intercoordination is summarized and operation essentials and attentions of the heaving operation are illustrated in this article. According to different geological conditions and design requirement, the reasonable and efficient methods＇ of heaving are put forward, in order to avoid the damage of the pipeline and ensure the molding effect and trenching velocity.
