Construction Technique of Casting 40.6 m Simple-supported Beam in Place for Railway Passenger Dedicated Line with Self-propelled Travelling Die Carrier

Research purposes:Application of key technologies and techniques of self-propelled travelling die carrier casts the long span and large tonnage box beam in place for passenger dedicated line for the purpose of meeting the requirements of rapid construction the bridge of passenger dedicated line. Research results:The self-propelled travelling die carrier applied in casting box beam in place of Tianxinzhou Bridge of passenger dedicated line can be used in casting box beam in place for highway and railway, specially for the under 40 m span box beam of passenger dedicated line,and it also can be used in casting in place box beam on the soft and weak foundations on land and in inter-tidal zone,and under the condition of high pier.
