Offshore wind power generation gravity type foundation and installation method
The invention relates to the technical field of the offshore wind power industry, and particularly relates to an offshore wind power generation gravity type foundation and an installation method. A middle stand column is arranged in the center of the gravity type foundation, a plurality of slurry rising reserved channels penetrating through the middle stand column are formed in the middle stand column, and an octagonal box body is externally connected to the position below the middle of the middle stand column. The octagonal box body comprises a bottom plate, a box body outer wall and box body partition plates dividing the octagonal box body into a plurality of radial compartments. One side of each box body partition plate is connected with the outer wall of the middle stand column, and the other side of each box body partition plate is connected with the outer wall of the box body. Gaps are reserved between the bottoms of the box body partition plates and the bottom plate to serve as water penetrating holes. A plurality of water inlet valves are installed on the lower portion of the outer wall of the box body. A foundation expansion toe is arranged at the bottom of the gravity type foundation. According to the offshore wind power generation gravity type foundation and the installation method, the foundation bed slurry rising technology is used, the gravity type foundation and a rock block foundation bed are connected into a whole, gaps of the rock block foundation bed are densely filled with cement mortar, the rock block foundation bed and a toe protection prism act together, the foundation bed is stable, sea wave drawing and brushing are prevented, and sedimentation is avoided.
本发明涉及海上风电行业技术领域，具体为一种海上风力发电重力式基础及安装方法。重力式基础的中心为中立柱，中立柱内开设有多个贯穿中立柱的升浆预留通道，中立柱中部以下外接八角形箱体，八角形箱体包括底板、箱体外壁和将八角形箱体分隔成若干个辐射状隔舱的箱体隔板，箱体隔板一侧与中立柱外壁连接，箱体隔板另一侧与箱体外壁连接，箱体隔板底部与底板之间留有空隙作为穿水孔，箱体外壁的下部安装有多个进水阀门，重力式基础的底部设有基础扩展趾。本发明使用基床升浆工艺，将重力式基础与块石基床连接成整体，并将块石基床的缝隙使用水泥砂浆填充密实，与护趾棱体共同作用，保证基床稳定，防止海浪掏刷，不发生沉降。
