Large-diameter combined cylinder, deepwater foundation, wind power foundation and static sinking construction method
The invention relates to the field of maritime work, in particular to a large-diameter combined cylinder, a deepwater foundation, a wind power foundation and a static sinking construction method.The cylinder body of the large-diameter combined cylinder is filled with filler and comprises a reinforced concrete cylinder and a steel cylinder which are sequentially arranged in the length direction of the cylinder body, and the reinforced concrete cylinder is located above the steel cylinder; the reinforced concrete cylinder and the steel cylinder are arranged in a sealed mode. According to the large-diameter combined cylinder, the corrosion problem of a splash zone is solved through the reinforced concrete cylinder, and meanwhile the large-diameter combined cylinder can adapt to more geological conditions through the steel cylinder. The combined cylinder combines the advantages that the weight of the upper reinforced concrete cylinder is large (because the strength-weight ratio of concrete is small, and part of the part above the water surface is dry volume weight), and the lower steel cylinder is small in sinking friction resistance in underwater soil; the tension performance of the lower steel cylinder is better than that of the upper reinforced concrete cylinder, the characteristics that the lateral pressure of the filler in the cylinder is increased along with depth increase and the cylinder wall tension is increased due to the circumferential tension of the cylinder are matched, and the structural performance is excellent.
本发明涉及海工领域，特别是大直径组合筒、深水基础、风电基础及静力下沉施工方法，其中大直径组合筒的筒体内填充有填料，筒体包括沿筒体长度方向依次设置的钢筋混凝土筒和钢筒，钢筋混凝土筒位于钢筒的上方，钢筋混凝土筒与钢筒之间封闭设置。本申请的一种大直径组合筒，通过钢筋混凝土筒来解决浪溅区腐蚀问题、同时利用钢筒能够适应更多地质条件。组合筒结合了上部钢筋混凝土筒重量大(因为混凝土强重比小，且部分水面以上是干容重)，下部钢筒在水下土中下沉摩阻力小的优势；下部钢筒受拉性能比上部钢筋混凝土筒好，匹配筒内填料随深度增加侧压力增加，筒体环向拉力引起筒壁拉力增加的特点，结构性能优。
