Research on Integrated Bridge Builder Based on Mobile Factory
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.
