1、空心板梁的现浇、预制本标段桥梁梁板总共344片,其中8米钢筋砼空心板72片,16米预应力空心板梁216片,16米现浇T梁56片。8米钢筋砼空心板预计设置台座4个,16米预应力空心板梁预计设置台座16个,张拉、注浆完成后,采用龙门吊将梁板移到存梁区,再利用炮车将梁板运到架桥机处,架桥机直接起吊进行架梁作业。拟计划组织三个作业班组(钢筋、模板、泥水、预应力张拉)平行施工,充分发挥专业化施工队伍的人员经验和机械设备能力。准备台座绑扎底、腹板钢筋安装波纹管安装内模制作内模安装侧模、端模浇注底板混凝土绑扎顶板钢筋脱模穿钢绞线束双控张拉、锚固封锚、压浆封端梁体编号出槽移梁存放钢绞线制作钢绞线检验制

7、便道填筑20cm厚砂砾石,台座基础另行按图进行开挖浇筑钢筋砼进行加固。1.3台座制作台座地基进行压实处理后,在规划的台座位置开挖第一层基础,宽130cm,深25cm,按图进行第一层基础施作,要求平齐于原地面。待砼硬化后,再进行第二层台座的施工,第二层台座顶面四周嵌固50等边角钢,大面平整度控制在1mm内,用2米的水平尺或水准仪每2米检测,面层下9cm处预留对拉螺栓孔,台座砼顶面硬化前铺设5mm厚钢板,与砼贴合。砼台座浇筑时按要求设置一定的反拱,
