Pile box barrel composite foundation for offshore wind power and construction method thereof
The invention discloses a pile box barrel composite foundation for offshore wind power. The pile box barrel composite foundation comprises a single pile and a barrel body, wherein the barrel body comprises an inner barrel body, an outer barrel body, a negative pressure barrel top plate and a plurality of negative pressure barrel partition plates; the inner barrel body is coaxially arranged in an inner cavity of the outer barrel body and arranged on the single pile in a sleeving mode; the inner barrel body and the single pile are connected into a whole through grouting; the negative pressure barrel top plate is arranged between the upper portion of the inner barrel body and the upper portion of the outer barrel body in a sealing and covering mode, so that a negative pressure barrel is formed on the lower portion of the negative pressure barrel top plate, an open box barrel is reserved on the upper portion of the negative pressure barrel top plate, and the interior of the open box barrelis divided into a plurality of weight areas through a plurality of rib plates; the plurality of negative pressure barrel partition plates are evenly connected into the negative pressure barrel in theradial direction to divide the negative pressure barrel into a plurality of negative pressure cabins; and after the barrel body penetrates into seabed soil and the negative pressure barrel top platereaches the designed elevation, the weight areas of the open box barrel are filled with riprap weights, and the box-shaped foundation is formed. The invention further discloses a construction method of the pile box barrel composite foundation for offshore wind power. By means of the pile box barrel composite foundation for offshore wind power and the construction method thereof, the anti-overturning bearing capacity can be improved, and the buried depth of the single pile is reduced.
本发明公开了一种海上风电的桩箱桶复合基础，包括单桩和桶体；桶体包括内、外桶体、负压桶顶板和若干负压桶隔板，内桶体同轴地设置在外桶体的内腔中并套设在单桩上，内桶体与单桩之间通过灌浆连接为整体；负压桶顶板封盖在内、外桶体的上部之间，使负压桶顶板的下部形成负压桶，并使上方预留一个开口箱桶，该开口箱桶内通过若干肋板分成若干压重区域；若干负压桶隔板径向均布地连接在位于负压桶内，将负压桶分成若干负压舱室；在桶体贯入海底泥土且负压桶顶板达到设计标高后，在开口箱桶的各个压重区域内装填抛石压重，形成箱形基础。本发明还公开了一种海上风电的桩箱桶复合基础的施工方法。本发明能提高抗倾覆承载能力，减少单桩埋深。
