[0001] 本申请公开了一种海中引桥高桩承台钢吊箱封底混凝土快速施工方法，包括施工准备、混凝土运输与就位、快速直灌浇筑、分层振捣、连续作业及养护监测六大步骤：通过在钢吊箱顶部安装双串筒多点布料管系统，搭配容积≥10m³ 混凝土罐车实现 C30 封底混凝土直灌，选择潮位低于 ‑ 1.00m 时连续浇筑，采用 φ50 振动棒分层振捣，浇筑后覆盖薄膜养护并保持连通器连通，同步监测限位与水位差。本发明摒弃传统汽车泵，单承台最大105m³方量浇筑耗时≤2小时，大幅提升施工效率，减少栈桥空间占用，混凝土密实度≥98%，渗漏率低，适配海中低潮位短窗口期施工需求，保障工程安全质量，降低施工成本，具有显著的实用性和经济效益。
