Offshore wind plant submarine cable embankment penetrating construction method based on trenchless directional drilling technology
The invention relates to an offshore wind power plant submarine cable embankment penetrating construction method based on a trenchless directional drilling technology, and belongs to the field of offshore wind power construction technologies. The construction method comprises the following steps: measuring, positioning and paying off; constructing a cofferdam; installing and welding pipelines; preparing slurry; drilling a guide hole; graded reverse expansion hole forming and pipeline back dragging are carried out; and compacting and grouting. The construction method has the advantages that safety and reliability are achieved, the construction process is simple and rapid, the construction period can be effectively shortened, smooth seawall surface roads are guaranteed, and traffic is not affected.
本发明涉及一种基于非开挖定向钻孔技术的海上风电场海缆穿堤施工方法，属于海上风电施工工艺领域；该施工方法包括以下步骤：测量定位放线；围堰施工；管道安装组焊；泥浆配制；导向孔钻进；分级反扩成孔及管道回拖；压密注浆。该施工方法的优点在于安全可靠、施工过程简单快速，可以有效缩短工期，同时确保海堤表面道路的畅通，不影响交通。
