Offshore pile splicing anti-corrosion process of offshore wind power foundation steel pipe pile
The invention discloses an offshore pile splicing anti-corrosion process of an offshore wind power foundation steel pipe pile. The offshore pile splicing anti-corrosion process comprises the steps ofupper steel pipe pile manufacturing, offshore field pile splicing preparation, steel pipe pile butt joint, steel pipe pile welding and coating repairing. When the steel pipe pile butt joint process iscarried out, an upper steel pipe pile is hoisted and aligned with the lower steel pipe pile in the circumferential direction, the longitudinal weld joint of the upper steel pipe pile and the longitudinal weld joint of the lower steel pipe pile are staggered by 180 degrees, the upper steel pipe pile falls slowly, the root gap of a butt joint groove of the upper steel pipe pile and the lower steelpipe pile is controlled to be 10 mm, a staggered platform of the butt joint groove is smaller than 3 mm, and the perpendicularity of the upper steel pipe pile is controlled; when the steel pipe pile welding process is carried out, carbon dioxide arc welding is adopted; when the coating repairing process is carried out, nanometer anticorrosive paint is adopted for anticorrosive construction, and the method comprises the steps of polishing and cleaning, three times of nanometer paint bottom coating, three times of nanometer paint surface coating and repairing. Reliable technical support can be provided for the drilling and driving construction process of the steel pipe pile.
本发明公开了一种海上风电基础钢管桩的海上接桩防腐工艺，包括以下流程：上部钢管桩制作、海上现场接桩准备、钢管桩对接、钢管桩焊接和涂装修复；进行钢管桩对接流程时，将上部钢管桩吊起，与下部钢管桩在圆周方向对齐，并使上部钢管桩的纵焊缝与下部钢管桩的纵焊缝错开180°，缓慢下落上部钢管桩，控制上部钢管桩与下部钢管桩的对接坡口的根部隙为10mm、对接坡口错台小于3mm以及上部钢管桩的垂直度；进行钢管桩焊接流程时，采用二氧化碳气体保护焊；进行涂装修复流程时，采用纳米防腐涂料进行防腐施工并包括以下步骤：打磨清理、三次纳米涂料底涂、三次纳米涂料面涂和修补。本发明能为钢管桩实现钻打施工工艺提供可靠的技术支持。
