移动模架现浇预应力混凝土箱梁施工技术

The working techniques of casting the prestressing concrete box girder with mobile form and bracket

移动式模架整孔原位现浇梁,具有结构简单,工期与质量能保证,工序循环基本不变,流水作业,易于管理,机械化程度高,施工不受桥下交通的干扰和限制等特点。随着铁路跨越式发展战略的实施,大量的客运专线桥梁将采用移动模架造桥机现浇施工。文章简要介绍了移动模架造桥机的结构特点及施工特点。

Mobile form and bracket is the original cast in place box section bridges with its merits of easy structure, convenient management, conveyor system and high mechanization can not only guarantee both prompt completion and good quality of projects but also prevent building work from interruption and constraints from traffic under bridges. With the implementation of spanning development strategy of railway, this kind of bridge fabrication machine with mobile form and bracket will be adopted to build a large number of bridges that are for passenger transport only. The ＇paper aims to giving a brief introduction to structural characters and working characters of bridge fabrication machine with mobile form and bracket.
