Raft gravity type jacket offshore wind turbine foundation and construction method thereof
The raft gravity type jacket offshore wind turbine foundation comprises a plurality of abutments and jacket structures installed on the abutments, each jacket structure is provided with a plurality of steel pipe pile legs, each abutment comprises a bottom plate, a connecting pile section is arranged in the center of the upper surface of each bottom plate, and the connecting pile sections are connected with the steel pipe pile legs. The connecting pile section is connected with the steel pipe pile leg through a connecting structure, the connecting structure comprises first shear keys evenly arranged on the outer wall of the steel pipe pile leg, second shear keys are arranged on the inner wall of the connecting pile section, and a grouting annular space is arranged between the connecting pile section and the steel pipe pile leg. The method is suitable for sea areas with poor geological conditions such as a thin covering layer or a rock foundation, and has the advantages that construction equipment is not limited, the construction difficulty is small, and the offshore construction operation period is short.
本发明提供了一种筏板重力式导管架海上风机基础及其施工方法，包括多个墩台和安装在多个墩台上的导管架结构，导管架结构具有多个钢管桩腿，墩台包括底板，底板的上表面中心设置连接桩段，连接桩段与钢管桩腿通过连接结构相连接，连接结构包括均匀布置于钢管桩腿外壁的第一剪力键，连接桩段内壁上布置有第二剪力键，连接桩段与钢管桩腿之间设置为灌浆环形空间。本发明适用于较薄覆盖层或岩质地基等地质条件较差海域，具有施工设备不受限制、施工难度小、海上施工作业周期短的优点。
