Design and Application of Form Traveler for Dismantling Continuous Beam Bridge

摘要:

京泰大桥老桥主桥连续梁共四幅，跨越新通扬运河，跨径为38.5 m+60 m+38.5 m，共拆除梁长548 m。连续梁拆除施工采用挂篮逆施工，采用拆桥挂篮作为主要设备，重点介绍该设备的结构和应用，为后续桥梁拆除施工提供借鉴。

Abstract:

There are four continuous beams of the main bridge of the old Jingtai Bridge. The bridge spans the Xintongyang Canal. Its spans are 38.5 m + 60 m + 38.5 m. The total length of dismantling beam is 548 m. The reverse construction of form traveler is used to dismantle the continuous beam. The main equipment to dismantle bridge is the form traveler. The structure and application of this equipment are specially introduced, which provides the reference for the dismantling construction of the similar bridges.
