Research on Key Technology of Continuous Beam Translation Construction of Turnout in Complex Environment
In general,the construction of replacing turnout beam with existing railway turnout beam has the characteristics of extremely complex site conditions,space limitation and extremely high safety requirements.Combined with the construction of cast-in-place beams for the turnout of the newly built Chengdu South Link Right Line Extra Large Bridge,this article analyzes the safety of the beam support system under various working conditions and the synchronous control during the translation process,and emphatically controls the key operation points in the whole process of the cast-in-place and translation of the continuous beam to ensure the safety of the construction process and existing railway operation process;the study and analysis of the improvement technology and translation construction organization of existing railway bridges in complex environments are of significant importance for improving operational safety indicators,technical safety reliability,and construction safety control capabilities,and can provide reference value for follow-up projects.
