1、 1 向莆铁路 FJ-1A 标（金溪特大桥） 实施性施工组织设计 摘要 本桥我们选择富有经验的专业队伍进行施工， 按多个工作面同时进行平行 流水作业，以缩短工期。桩基采用冲击钻钻进成孔，直升导管法灌注成桩；承 台采用机械配合人工放坡开挖； 圆端形实体桥墩和流线型圆端实体墩一次立模 浇筑成型；施工中，对桩基、承台、墩（台）身，形成平行和流水作业的局面。 陆上承台施工采用机械配合人工开挖，基坑开挖时，备足抽水设备，及时 排除地下水。模板采用大块定型钢模板，混凝土一次浇筑成型，插入式振动棒 分层振捣密实。水中承台采取修建栈桥、筑岛围堰的方法施工。其中的难点就 在水上施工。 关键词：关键词：栈桥；承台
