Novel offshore wind power suction bucket foundation bucket skirt structure capable of preventing soil plug upheaval
The invention provides a novel offshore wind power suction bucket foundation bucket skirt structure capable of preventing a soil plug from upheaval, which comprises a bucket skirt, a bucket top plate and a middle support column, and is characterized in that a plurality of concave soil discharge grooves are annularly formed in the lower end of the bucket skirt at intervals, and coherent stiffening structures are arranged from the soil discharge grooves, the bucket skirt, the bucket top plate to the middle support column; the stiffening structure is connected with the soil discharging groove, the through skirt, the barrel top plate and the middle supporting column to form an overall stress structure. The soil discharging groove structure arranged at the bottom of the barrel skirt can smoothly discharge the replaced soil around the barrel skirt to the outer side in the sinking process of the suction barrel, the replaced soil is effectively prevented from entering the barrel to form internal soil plug upheaval, the situation that the sinking resistance of the barrel body is increased due to local compaction is avoided, and it is ensured that the suction barrel foundation sinks and is installed in place.
本发明提供了一种防止土塞隆起的新型海上风电吸力桶基础桶裙结构，所述桶裙结构包括桶裙、桶顶板和中部支撑柱，其特征在于：桶裙下端间隔环向布置有若干向内凹的排土槽，排土槽、桶裙、桶顶板至中部支撑柱设置连贯的加劲结构，加劲结构与排土槽、通裙、桶顶板至中部支撑柱连接构成整体受力结构。本发明桶裙底部设置的排土槽结构能够在吸力桶下沉过程中将桶裙周围的置换的土体平滑地向外侧排出，有效防止置换的土体进入桶内形成内部土塞隆起，避免产生局部挤密而增大桶体下沉阻力，确保吸力桶基础下沉安装到位。
