Anti-scour embracing type abutment structure of offshore wind power single pile foundation
According to the anti-scouring encircling type abutment structure of the offshore wind power single-pile foundation, the encircling type abutment structure is arranged on the outer side of a pile leg of the single-pile foundation, the outer side of the pile leg is wrapped with an abutment, and substances such as seawater and silt are prevented from scouring the pile leg through blocking of the abutment; the abutment and the mud surface are fixed through the spiral piles, when the pile legs of the single-pile foundation have large lateral displacement on the mud surface, the surrounding abutment structure can play a blocking role, the horizontal bearing capacity of the single-pile foundation is increased, and deformation of the single-pile foundation is reduced; in addition, the sand conveying pipe can supplement scouring pits around the abutment in time. The structure is simple, the construction difficulty is small, the double effects of preventing the single-pile foundation from being scoured and enhancing the horizontal rigidity are achieved, and practicability is high.
本发明提供一种防冲刷的海上风电单桩基础的环抱式墩台结构，在单桩基础的桩腿外侧设置环抱式墩台结构，墩台包裹于桩腿外侧，通过墩台的阻隔防止海水及泥沙等物质对桩腿的冲刷；通过螺旋桩使得墩台与泥面实现固定，当单桩基础的桩腿在泥面处出现较大侧移时，环抱式墩台结构能起到阻挡的作用，增加了单桩基础的水平承载力，降低了单桩基础的变形；另外输砂管能对墩台周围的冲刷坑进行及时补充。本发明结构简单，施工难度小，具有对单桩基础防冲刷和加强水平刚度的双重效果，实用性强。
