Large underwater steel cylinder foundation for offshore wind power and construction method thereof
The invention relates to a large underwater steel cylinder foundation for offshore wind power and a construction method thereof, the steel cylinder foundation comprises a steel cylinder and a jacket, the bottom of the steel cylinder is provided with a tooth blade part convenient for rock embedding, the top of the inner wall of the steel cylinder is provided with a plug-in assembly and a pile leg used for fixing the bottom of the jacket, and a gap between the pile leg and the plug-in assembly is reinforced through grouting. The offshore wind turbine tower drum is fixed on the jacket; the construction method comprises the steps of steel cylinder manufacturing; transporting the steel cylinder; assembling a steel cylinder vibration sinking hammer group; steel cylinder pile sinking; foundation pile legs of the jacket are fixed; and steel cylinder riprap covering. The method effectively solves the problems of large rock-socketed depth, low construction efficiency, long open-sea operation time, high cost investment, more professional equipment investment and the like in traditional offshore wind power rock-socketed pile foundation construction.
本发明是一种海上风电用大型水下钢圆筒基础及其施工方法，钢圆筒基础包括钢圆筒、导管架，钢圆筒底部设有方便嵌岩的齿刃部，钢圆筒内壁顶部设有插接组件，用于固定导管架底部的桩腿，且桩腿和插接组件之间的缝隙通过注浆加固，海上风机塔筒固定在导管架上；施工方法包括钢圆筒制作；钢圆筒运输；钢圆筒振沉锤组组装；钢圆筒沉桩；导管架基础桩腿固定；钢圆筒抛石覆盖。本发明有效地解决了传统海上风电嵌岩桩基础施工的嵌岩深度大、施工效率低、外海作业时间长、成本投入大、专业设备投入较多等问题。
