Offshore wind power single pile foundation and construction method thereof
The invention discloses an offshore wind power single pile foundation and a construction method thereof.The offshore wind power single pile foundation comprises a bearing assembly, a single pile body and a plurality of positioning piles, the bearing assembly is provided with a main pile mounting hole located in the center of the bearing assembly, a filling area arranged around the main pile mounting hole and a plurality of auxiliary pile mounting holes formed around the main pile mounting hole at intervals, the filling area is filled with stones, the multiple positioning piles correspond to the multiple auxiliary pile mounting holes one to one, and the positioning piles slidably penetrate through the auxiliary pile mounting holes. The positioning pile is provided with a grouting channel, grouting is conducted on the stone in the filling area and the seabed soil body on the periphery of the positioning pile through the grouting channel to form a grouting reinforcement area, and the single pile body slidably penetrates through the main pile mounting hole. According to the offshore wind power single pile foundation, the bearing assembly is arranged, the protection area of the single pile body is enlarged, protection of soil around the pile is achieved by combining the riprap and grouting reinforcement technology, and therefore the problem that the periphery of the pile is exposed due to scouring is solved.
本发明公开了一种海上风电单桩基础及其施工方法，所述海上风电单桩基础包括承载组件、单桩本体和多个定位桩，承载组件呈环形，承载组件具有位于其中心的主桩安装孔以及环绕主桩安装孔设置的填充区和环绕主桩安装孔间隔布置的多个辅助桩安装孔，填充区内填充有石块，多个定位桩与多个辅助装安装孔一一对应，定位桩可滑动地贯穿辅助桩安装孔，定位桩具有注浆通道，通过注浆通道向填充区的石块中和定位桩周侧的海底土体中注浆以形成注浆加固区，单桩本体可滑动地贯穿主桩安装孔。本发明的海上风电单桩基础，通过设置承载组件，扩大单桩本体的防护面积，结合抛石和注浆加固工艺实现桩周土体的防护，从而解决冲刷带来的桩周暴露问题。
