Single pile-negative pressure barrel-transition section offshore wind power foundation structure and construction method
The invention discloses a single pile-negative pressure barrel-transition section offshore wind power foundation structure and a construction method. The single pile-negative pressure barrel-transition section offshore wind power foundation structure comprises a single pile, a negative-pressure barrel and an internally-inserted transition section, the negative-pressure barrel sinks to the designed elevation of the outer side of the single pile, and a first circular seam is formed between the negative pressure barrel and the single pile; the internally-inserted transition section is embedded in the single pile; a second circular seam is formed between the internally-inserted transition section and the single pile, and grouting materials are poured between the first circular seam and the second circular seam; and a grouting space is formed between the negative pressure barrel and the seabed mud surface, and grouting materials are poured into the grouting space. The construction method comprises the steps that the single pile is driven; the negative pressure barrel is installed and sinks; the grouting materials are poured into the negative pressure barrel; the grouting materials are poured between the negative pressure barrel and the single pile; the internally-inserted transition section is installed; and the grouting materials are poured between the internally-inserted transition section and the single pile. The procedures of piling, sinking installation of the negative pressure barrel, installation of the transition section and the like are closely connected in series and in a linked mode through grouting, the open sea construction assembly concept is fully embodied, the construction period is short, and the construction efficiency is high.
本申请公开了“单桩‑负压桶‑过渡段”海上风电基础结构及施工方法，该结构包括：单桩、负压桶和内插式过渡段，负压桶下沉至单桩外侧的设计标高，负压桶与单桩之间形成第一环缝；内插式过渡段内嵌于单桩设置；内插式过渡段与单桩之间形成第二环缝，第一环缝和第二环缝之间均灌注灌浆料；负压桶和海底泥面之间形成有灌浆空间，灌浆空间内灌注有灌浆料。该施工方法包括：单桩打入；负压桶安装及下沉；负压桶内灌注灌浆料；在负压桶和单桩之间灌注灌浆料；安装内插式过渡段；在内插式过渡段和单桩之间灌注灌浆料。本申请通过灌浆将打桩、负压桶下沉安装以及过渡段安装等工序紧密串联和衔接，充分体现外海施工装配化理念，施工周期短，施工功效高。
