Protective structure for single pile scouring of socketed pile type tidal current energy water turbine foundation
The invention discloses a protection structure for single pile scouring of a socketed pile type tidal current energy water turbine foundation, which comprises a sleeve, an elliptical flow baffle, a first square flow baffle and a second square flow baffle, and is characterized in that the sleeve is arranged outside a pile foundation in a sleeving manner; the oval flow baffle is fixed outside the sleeve, and the oval flow baffle is a circular truncated cone with a circular top and an oval bottom. According to the protection structure for scouring the single pile of the socketed pile type tidal current energy water turbine foundation, by arranging the oval flow baffles, on one hand, direct impact of undercurrent in front of the pile on a bottom seabed is weakened through buffering of the inclined faces of the oval flow baffles, and the scouring effect of water flow on soil around the pile is weakened; the normal over-current capability is not influenced; and water flow in front of the pile is dispersed through the two square flow baffles, direct impact of the water flow on the pile foundation is reduced, and violent digging and brushing of horseshoe vortexes formed by underwater water flow in front of the pile on a bottom seabed are dispersed.
本发明公开了一种用于嵌岩桩式潮流能水轮机基础单桩冲刷的防护结构，包括套筒、椭圆形挡流板、第一方形挡流板和第二方形挡流板，其中，所述套筒套设于桩基的外部；所述椭圆形挡流板固定于套筒外，椭圆形挡流板为顶部是圆形、底部是椭圆形的圆台。该用于嵌岩桩式潮流能水轮机基础单桩冲刷的防护结构，通过设置椭圆挡流板，一方面通过其斜面的缓冲削弱了桩前下潜流对底部海床的直接冲击，削弱了水流对桩周土体的冲刷作用，另一方面由于两侧短轴方向宽度较小，不对正常过流能力造成影响；并通过两扇方形挡流板分散了桩前水流，降低了水流对桩基的直接冲击，分散桩前下潜水流形成的马蹄涡对底部海床的剧烈掏刷。
