摘要
为提升海上风电场风机间非掩埋电缆后保护施工的作业效率,降低施工成本,综合运用多波束技术和侧扫声呐技术,对非掩埋电缆后保护施工作业区进行精确的地形地貌测绘.根据测绘结果,结合MS1000成像声呐和船舶定位与超短基线水下定位技术,监控和定位液压释放架布放混凝土联锁排,对非掩埋电缆进行后保护施工作业.实际应用结果表明,该施工技术能提高布放混凝土联锁排的作业效率,降低施工成本,取得良好的社会和经济效益.
Abstract
In order to improve the working efficiency and reduce the construction cost of the non-buried cable rear protection construction between offshore wind turbines,the multi-beam technology and side-scan sonar technology are comprehensively used to accurately map the topography and geomorphology of the non-buried cable rear protection construction area.According to the surveying and mapping results,combined with MS1000 imaging sonar and ship positioning and Ultra Short Base Line underwater positioning technology,concrete interlock row was laid on the hydraulic release frame for monitoring and positioning to carry out post-protection construction of the unburied cable.The construction technology improves the efficiency of interlocking concrete laying.Finally,the operation efficiency is improved and the construction cost is reduced,and good social and economic benefits are achieved.
