摘要
海管挖沟可以增加海管的稳定性、防止海管漂移和渔船抛锚拖拉等事故。文中对国内外挖沟机发展现状进行了分析,通过国内海管后挖沟工程案例介绍了犁式挖沟和喷射式后挖沟技术在海管挖沟中的应用,并对我国海管挖沟项目挖沟机选型提出建议。
Pipeline trenching can benefit pipeline stability,prevent pipeline drift and protect pipeline from activity of fishing.This paper analyzes the development of pipeline trencher both in domestic and international.Based on the actual pipeline post-trenching cases in china,plough trenching and jet trenching are introduced.Some advices on trencher selection in domestic pipeline post trenching project are proposed.
