Research on Through-hole Technology of Upward Movable Formwork Bridge Fabrication Machine
In high-speed railway cast-in-place box girder engineering,the rational use of the upward movable formwork bridge fabrication machine is conducive to shortening the construction period,improving the mechanized level of bridge fabrication,and fully maintaining the construction safety.Through-hole is the premise of carrying out lower hole construction,which can provide necessary support for the safe construction of the movable formwork bridge fabrication machine during the construction period.Taking Shenyang-Baihe High-speed Railway project as an example,this paper introduces its process principle,deeply analyzes the through-hole technology of upward movable formwork bridge fabrication machine,and puts forward strategies to ensure construction safety from aspects such as mold opening inspection,through-hole inspection and mold closing inspection,so as to ensure the smooth construction.
