Underwater pile foundation scouring protection device with scour prevention holes
The invention discloses an underwater pile foundation scouring protection device with scour prevention holes, and belongs to the technical field of offshore wind power pile foundation protection. Thescouring protection device comprises a plurality of scouring protection modules arranged in an array mode, wherein the scouring protection modules are connected with one another and laid on a seabed around an offshore wind power pile, and a slope in transition to the seabed is arranged at the edge of the scouring protection device; and a plurality of scouring holes are uniformly distributed in thescouring protection modules. According to the device, the space at the bottom of an offshore wind power pile foundation is divided into the vertical scouring holes with very small sections, after water flow flows around a cylindrical pile column, horseshoe vortex formed around the pile foundation develops downwards to directly impact the scouring protection device, vertical impact components aredissipated in scouring hole structures, due to the fact that the section of each scouring hole is small, the water flow can be effectively divided, the depth of the scouring holes can ensure that thedisturbance effect of scouring water flow is dissipated before reaching the bottom, and therefore the seabed at the bottom of the offshore wind power pile foundation is protected against scouring influences.
本发明公开的一种带防冲刷孔的水下桩基础冲刷防护装置，属于海上风电桩基础防护技术领域。包括若干阵列排布的冲刷防护模块，若干冲刷防护模块相互连接，铺设在海上风电桩柱周围的海床上，冲刷防护装置边缘处设有向海床过渡的斜坡；冲刷防护模块上均布有若干冲刷孔。该装置将海上风电桩基础底部的空间分割成截面很小的竖直的冲刷孔，水流绕流圆柱形桩柱以后，在桩基础周围形成的马蹄涡乱流向下发展直接冲击冲刷防护装置，竖直冲击分量在冲刷孔结构中消散，由于每个冲刷孔的截面较小，可以有效分割水流，冲刷孔的深度可以确保冲刷水流的扰动作用在到达底部之前得到消散，从而保护海上风电装基础底部的海床不受冲刷影响。
