The bridge will effectively promote the social and economic development in this region after completion.



 

Incremental launching tech with walking jacks were used to position the huge gantries - the steel box girders are lifted to the brackets and welded into one piece and then pushed horizontally across the viaduct and then the lifting and welding of other sections of the steel box girders at both ends put into effect. All parts and element units were pre-made in the factory yard and delivered to the worksite before the erection. The first four segments were hoisted onto the brackets and assembled as a whole, a 20-meter steel guiding beam was installed and the fifth segment was hoisted and welded in place after being pushed forward for a certain distance with two 300 t truck cranes.
