Research and Application of Cast-in-situ Box Girder Construction Technology of Offshore High Pier Mobile Mold Frame
With the continuous domestic development of bridge construction,the cast-in-situ beam technology of mobile mold base construction has been broadly applied.Due to complex environmental factors such as currents,waves and ocean winds,mobile frame construction faces specific challenges in offshore bridge construction.Taking the construction of Longmen Bridge as a case study,this paper discussed a series of challenges such as mobile mold frame assembly under complex offshore conditions,construction under different working conditions,curved vias,double-width cross-working,and self-regression.Via innovative traditional technology,this study contributes to the safet and orderly construction of the cast-in-situ box girder of the mobile mold frame of the offshore high pier.
