Construction Technology of Large Curved Continuous Beam on Short Pier of Manwan Bridge
This paper takes the continuous beam of 4×28 m ballasted track prestressed concrete turnout of Man-wan Bridge is taken as the research object,and adopts a series of technical measures,such as"native cattle method"support system construction,large section arc formwork installation and reinforcement,large area of con-crete one-time pouring construction key control.It simplifies the support system and formwork system of continu-ous beam,ensures the smooth completion of several key points in construction,ensures the safety and quality of bridge engineering,saves the construction period and cost,and also provides some ideas for reference for the con-struction of short pier continuous beam in similar projects.
