某特大桥梁场预制与移动模架施工方案比较

Comparing the scheme of prefabrication and moving of die carrier in large bridge space

针对荔枝沟特大桥原施工图设计方案无法满足工期的总体要求,提出了设置梁场预制架桥机架设方案和移动模架造桥机现浇施工方案,根据对上述两方案的经济、技术、工期、安全、质量等各方面的综合分析比较,决定采用设置梁场预制架桥机架设方案。

Aiming at the original design scheme could not meet constructional requirements of Lizhigou large Bridge, this article proposes two schemes： establishing prefabricated bridge machine and movable die carrier constructional style. The former was selected finally after combining with the later one from aspects of economy, skill, term, safety and quality and so on.
