港珠澳大桥东人工岛结合部非通航孔桥管线槽侧板预制工艺

Technology for prefabrication of side panels for cable grooves over non-navigable span of bridge at east artificial island for Hongkong-Zhuhai-Macao Bridge

港珠澳大桥东人工岛结合部非通航孔桥管线槽侧板是第一批采用清水混凝土的小型预制构件,质量要求高,以展示出良好的外观特性。文章详细论述了钢筋加工、模具装配、混凝土浇筑振捣、成品防护与吊装等各环节的精细化施工工艺,取得了良好效果。

The side panels for cable grooves over non-navigable span of bridge at east artificial island for Hongkong-Zhuhai-Macao Bridge are the first small precast components with fair-faced concrete, demanding high quality and showing good appearance. The paper discusses in detail the fine construction technology of steel processing, mold assembly, pouring concrete vibrators, product protection, lifting and so on. It achieved good results.
