城市轨道交通高架桥梁清水混凝土施工工艺研究

Research on Fair-faced Concrete Construction Technology for Urban Rail Transit Viaduct

城市轨道交通高架桥梁采用清水混凝土施工工艺,可以达到结构美观、节约成本、环保节能的多重效果,还同时具有美学价值和景观效应。通过清水混凝土技术在常州轨道交通1号线部分工程中的成功应用,总结了城市轨道交通高架桥梁清水混凝土施工工艺参数、墩柱施工过程控制和箱梁施工过程控制措施。

Adopting fair-faced concrete construction technology for urban rail transit viaduct,it can achieve the effects of beautiful structure,cost saving,environmental protection and energy saving,and has aesthetic value and landscape effect at the same time. By the successful application of the fair faced concrete technology in partial work of Changzhou Rail Transit Line 1,the construction technology parameters,the construction process control measures for the box girders and pier columns with fair-faced concrete of the urban rail transit viaduct were summarized.
