Offshore wind power generation pile foundation using anchor cable as counter force and construction method of offshore wind power generation pile foundation
The invention relates to an offshore wind power generation pile foundation using an anchor cable as counterforce and a construction method thereof, and solves the problems that the offshore wind power generation pile foundation is difficult to dredge and cannot be constructed when encountering a thicker silt layer. The pile foundation structure sequentially comprises anchor cables, an underwater concrete leveling layer and a concrete cylinder body from bottom to top, a sludge layer and a rock layer are arranged below the underwater concrete leveling layer, the anchor cables are evenly distributed on the plane of the underwater concrete leveling layer, the lower ends of the anchor cables are anchored into the rock layer by 10-30 meters, and the lower ends of the anchor cables are anchored into the rock layer by 10-30 meters. The upper ends of the anchor cables penetrate through the silt layer and the underwater concrete leveling layer and are exposed out of the upper surface of the underwater concrete leveling layer; the concrete cylinder body is centrally poured on the underwater concrete leveling layer, the stay cables are arranged on the periphery of the lower end of the concrete cylinder body, and the lower ends of the stay cables are fixed to the upper ends of the anchor cables. Sufficient anchoring force can be provided for the offshore wind turbine without removing a large amount of sludge on the seabed, the construction cost is greatly reduced, and the construction efficiency is improved.
本发明涉及一种利用锚索作反力的海上风力发电桩基及其施工方法，解决海上风力发电基础遇到较厚的淤泥层时清淤困难，无法施工的问题。本桩基结构从下到上依次包括锚索、水下混凝土找平层以及混凝土筒身，所述水下混凝土找平层下方为淤泥层和岩层，所述锚索在水下混凝土找平层平面上均匀分布若干根，锚索下端锚入岩层深度10～30米，锚索上端穿过淤泥层以及水下混凝土找平层，锚索上端露出水下混凝土找平层上表面；所述混凝土筒身在水下混凝土找平层上居中浇筑，混凝土筒身下端环周设置斜拉索，斜拉索的下端与锚索上端固定。本发明无需清除海底大量淤泥就能为海上风力涡轮机提供足够的锚固力，大大减少了施工成本，提高施工效率。
