Abstract Abstract：Research purposes： Steel tube arc bridge is one of the bridge types that is more extensively used in urban bridges of China.Especially on the navigable river bridge design,steel tube arc bridge is the preferred type.In consideration of the navigable demand of channel,the side assembled and integral lifting construction technology are more generally used when it comes to the construction part of this bridge.The integral lifting has two methods,including drag erection and the whole floating crane.In this paper, the whole hoisting construction technology of the main steel pipe tied arch bridge of Danyang Lvdong Bridge is studied, to from a set of detaild comprehensive construction technology of the whole floating crane erection of steel pipe tied arch bridge. Research conclusions： (1) The whole floating crane erection construction processes of steel pipe arc bridge include: preparations for construction of the floating crane, crane barge ship in place, the whole crane, synchronous retreat of floating crane ship, synchronous rotating clockwise by 90 degrees, synchronous moving toward the bridge, fine-tuning floating crane ship, main bridge in place, artificial siting precision adjustment, deconstruction, floating crane ship away from the scene. (2) The advantages of the whole floating crane construction technology of steel pipe arc bridge include: the main bridge assembly and approach bridge construction can be carried out in a synchronous way, which can shorten the construction period; The construction safety risk is small; The hoisting can be completed in a short time, only 2~3 h can be completed, the time of sealing is greatly shortened. (3) Using the floating crane erection construction of Danyang Lvdong Bridge, successfully completed the assembly task, therefore the whole erection construction on the existing channel has great promotion prospects and technical guidance.
