Flexible Application of Rapid Assembling Structure Technology in the Construction of Traffic Infrastructure

Along with the further development of the construction of traffic infrastructure, the series complex and major engineering appears unceasingly constantly. This text introduction is the engineering case history about the development and application of the assembly erecting and girder-replacing equipment on girder-quick-replacing on existing railway bridge, highway beam erecting crossing over railway trunk line and large-tonnage box beam erecting in high-speed railway. The emergency engineering structures equipment was developed based on the war preparedness assessment equipment and utilize the rapid assembling structure technology. Utilizing the rapid assembling structure technology properly to solve the problem has a safety credibility and can be assembled quickly. The method provides a dependable technique guarantee for the construction of traffic infrastructure.
