Abstract
The objective of this study is to guarantee the security of the erection of section girders for rail transit utilizing a U-box combined continuous girder.The Tianjin Binhai New Area Rail Transit project is employed as the engineering background for this study.The technical parameters of the suspension crane are determined,on-site construction preparatory measures are proposed,and the lifting scheme of the bridge crane at the bridge location is validated.Furthermore,a comprehensive introduction to the lifting construction process,loading of the section girder and acceptance standards for transport and installation is provided.As long as safety performance is guaranteed,the construction of the merging section can be carried out,which effectively ensures the accuracy of the section girder lifting in place,reduces the labor intensity and simplifies the lifting operation.The U-box segmental girder frame laying method proposed in this paper has been demonstrated to be an effective approach that meets the engineering construction requirements.The findings of this research will offer novel insights and techniques for the construction of U-box combined continuous girders for rail transit,thereby contributing to the accelerated advancement of urban rail transit infrastructure.关键词
