基于移动工厂的一体化筑桥机研究

Research on Integrated Bridge Builder Based on Mobile Factory

移动模板支架现浇梁施工因其环境适应性强、经济性好等优点得到广泛应用;但同样存在施工条件较差、自动化程度不高等缺点。针对此问题,依托某城市高架桥工程开展基于移动工厂的一体化筑桥机研究,并制定集封闭式厂房、钢筋部品制造及运输安装、混凝土自动布料及养护以及自动行走等功能于一体的流水线工艺流程;研究适应于超宽现浇梁施工的一体化筑桥机结构,其集成多种功能模块,可确保过孔时结构整体性和稳定性。采用有限元分析软件对筑桥机工作全过程进行仿真分析,结果证明不利工况下结构安全性可以得到保证。

The construction of cast-in-place beam with mobile formwork support has been widely used because of its strong environmental adaptability and good economy.But it also has the disadvantages of poor construction condition and low automation degree.To solve this problem,based on a city viaduct project,the research about the integrated bridge builder based on mobile factory is carried out.It clears the integrated closed workshop,steel parts manufacturing and transportation installation,concrete automatic distribution and maintenance and automatic walking and other functions in one assembly line process.An integrated bridge builder structure suitable for the construction of ultra-wide cast-in-place beams is studied.It integrates many functional modules and can ensure the integrity and stability of the structure when passing through holes.The finite element analysis software is used to simulate and analyze the whole process of the bridge construction machine,and the results show that the structural safety can be guaranteed under unfavorable working conditions.
