黄河公路大桥引桥部分采用 3 0m预应力混凝土箱梁。笔者就引桥的施工全过程 ,介绍了十分复杂的箱梁施工工艺和吊装各工序。从箱梁底模、钢模的制作 ,钢筋制作与绑扎 ,模板安装与拆除 ,孔道预留 ,混凝土工程 ,预应力钢丝张拉与锚固 ,预应力孔道灌浆到箱梁的吊装过程几方面均作了详细地叙述。因本工程采用多工种平行流水作业 ,且总体协调一致 ,故保质按期完成施工任务 Yellow River Highway Bridge part of the bridge using 30m prestressed concrete box girder. The author on the bridge of the whole process of construction, introduced a very complicated box girder construction process and lifting of the process. From the bottom of the box girder, the production of steel, steel production and banding, template installation and removal, channel reservation, concrete engineering, prestressed steel wire tension and anchorage, prestressed hole grouting to the box beam lifting process several aspects are Described in detail. Due to the project uses a multi-species parallel flow operation, and the overall coordination, so the warranty on schedule to complete the construction tasks
