Offshore wind power single pile foundation for reinforcing deep soft soil foundation
The invention provides an offshore wind power single pile foundation for reinforcing a deep soft soil foundation, and relates to the field of single pile foundations. The offshore wind power single-pile foundation comprises a steel pipe pile body and a reinforcing foundation, the reinforcing foundation comprises a plurality of pile bodies which are connected in an engaged mode, and the pile bodies are any one of cement mixing piles, high-pressure jet grouting piles and vibro-replacement gravel piles; the projection shape of the reinforcing foundation on the seabed surface is in a grid shape, the pile bodies located in the middle of the reinforcing foundation are densely arranged to form a positioning pile structure, and the steel pipe pile bodies are inserted into the positioning pile structure. The pile body is provided with an insertion section located below the seabed surface, and the insertion section of the pile body is arranged in a step-by-step decreasing mode in the radial direction away from the steel pipe pile body. Part of the pile bodies are further provided with turbulent flow sections protruding out of the seabed surface, and the turbulent flow sections of the pile bodies are arranged on the periphery of the steel pipe pile body in a dispersed mode to form a quincuncial pile array. Through the design of the turbulent flow sections of the quincuncial pile array, the seabed flow velocity is effectively disturbed, pile periphery scouring damage is avoided, and the stability of the whole single-pile foundation is guaranteed.
本发明提供了一种用于加固深厚软土地基的海上风电单桩基础，涉及单桩基础领域。该海上风电单桩基础包括钢管桩本体和加固基础，加固基础包括多个咬合相连的桩体，桩体为水泥搅拌桩、高压旋喷桩和振冲碎石桩中的任意一种；加固基础在海床面上的投影形状为栅格状，位于加固基础中部的桩体密集设置形成定位桩结构，钢管桩本体插装于定位桩结构中；桩体具有位于海床面以下的插入段，桩体的插入段在远离钢管桩本体的径向方向上呈逐级递减设置；部分桩体还具有凸出海床面以上的扰流段，桩体的扰流段在钢管桩本体的外周分散布置成梅花桩阵。通过梅花桩阵的扰流段设计，有效地扰动海底流速，避免了桩周冲刷破坏，保证了整个单桩基础的稳定性。
