Abstract:To advance the construction of smart ports,integrate shoreline resources,the first phase of the renovation of the container terminal in Luojing port area of Shanghai Port involves enlarging the old approach bridge,which is 877.81 m long,to a width of 40 m.Addressing the low efficiency of the“construction while opening to traffic”for the long approach bridge widening,challenges from tides and technological constraints,along with issues from unreasonable demolition processes and installation methods,we conduct an analysis of the constraining factors and a study on improving work efficiency.By adopting an optimized hoisting process (floating crane+bridge erection machine),innovating hoisting beams,applying sand cylinders for temporary fixation,and overcoming the influence of tides,efficient construction is achieved while maintaining traffic,with the construction period shortened by 50%.This solution successfully solved the problem of renovating a long approach bridge under complex conditions.The research results have significant demonstrative value for advancing smart port development and integrating shoreline resources.
