Offshore wind power negative pressure barrel-negative pressure pile composite foundation and construction process thereof
The negative-pressure barrel-negative-pressure pile composite foundation comprises a pile body, a negative-pressure barrel and a plurality of negative-pressure piles, the pile body is connected with the top of the negative-pressure barrel, the negative-pressure piles are arranged on the outer side of the negative-pressure barrel at intervals and connected with the negative-pressure barrel, the negative-pressure barrel and the negative-pressure piles are both settled into a seabed, and the negative-pressure barrel and the negative-pressure piles are arranged in the seabed. The bottom of the negative pressure pile and the bottom of the negative pressure barrel are open, and the bottom of the negative pressure pile is located below the bottom of the negative pressure barrel. According to the negative pressure barrel-negative pressure pile composite foundation provided by the invention, the negative pressure pile can be buried in deep soil with higher soil body strength, so that the bending bearing capacity, the compression bearing capacity and the tensile bearing capacity of the composite foundation are improved, and the composite foundation has better stability. And meanwhile, the negative pressure pile is located on the outer side of the negative pressure barrel, the overall bending-resistant section inertia moment of the composite foundation can be increased, and the overall bending resistance of the composite foundation is improved.
本发明公开了一种海上风电负压桶‑负压桩复合基础其建造工艺，负压桶‑负压桩复合基础包括桩体、负压桶和若干负压桩，桩体与负压桶顶部相连，若干负压桩间隔设置在负压桶的外侧并与负压桶相连，负压桶和负压桩均沉降入海床，负压桩的底部和负压桶的底部均敞开且负压桩的底部位于负压桶的底部的下方。本发明提供的负压桶‑负压桩复合基础，可以使负压桩埋入土体强度更强的深层土中，提高复合基础的抗弯承载能力、抗压承载能力和抗拉承载能力，并使复合基础具有更好的稳定性。同时，负压桩位于负压桶的外侧，可以提高复合基础整体的抗弯截面惯性矩，提高复合基础整体的抗弯性能。
