The invention discloses an offshore wind power pile foundation and a construction method based on the offshore wind power pile foundation, the offshore wind power pile foundation comprises a pile body and a partition plate, the pile body extends in the vertical direction, and an inner cavity extending in the length direction of the pile body is formed in the pile body, so that at least part of the pile body can be inserted into a seabed; the partition plate is arranged in the inner cavity in the radial direction of the pile body so as to divide the inner cavity into a first cavity and a second cavity in a sealed mode, the first cavity is formed in the upper side of the second cavity, and a one-way through-flow assembly is arranged on the partition plate. The one-way through-flow assembly enables liquid in the second cavity to flow into the first cavity in a one-way mode and can prevent liquid in the first cavity from flowing into the second cavity, so that the gravity borne by the offshore wind power pile foundation is increased by introducing seawater into the first cavity. The offshore wind power pile foundation and the construction method thereof have the advantages of being convenient to construct and high in construction efficiency.

本发明公开了一种海上风电桩基础和基于该海上风电桩基础的施工方法，所述海上风电桩基础包括桩体和隔板，所述桩体沿竖直方向延伸，所述桩体内设有沿其长度方向延伸的内腔，以使至少部分所述桩体可插至海床内；所述隔板沿所述桩体的径向设于所述内腔中，以将所述内腔密封分隔形成第一腔和第二腔，且所述第一腔设于所述第二腔的上侧，所述隔板上设有单向通流组件，所述单向通流组件可使第二腔中的液体单向流动至所述第一腔内并可阻止所述第一腔内的液体流至所述第二腔内，以适于通过向所述第一腔内通入海水增加所述海上风电桩基础所受的重力。本发明实施例的海上风电桩基础及其施工方法具有便于施工且施工效率较高的优点。
