贝雷钢栈桥在城市道路翻交施工中的应用

Application of Bailey Steel Trestle to Urban Road Reconstruction

在上海虹桥国际机场T1航站楼交通中心工程建设过程中,利用贝雷钢栈桥作为航站楼前高架的临时匝道。同时针对该钢栈桥需要起坡、转折以及与楼前高架相接等特殊条件限制,采用了相应的构造处理措施,既保证了施工安全,又满足了复杂环境中的道路翻交要求,实现了航站楼改造的不停航施工目标。

During construction of T1 terminal transportation center of Shanghai Hongqiao International Airport, Bailey steel trestle was used as a temporary overhead ramp. While at the same, the corresponding structure treatment measures have been adopted to deal with several special restrictions including ramp rise, turn and connection with viaduct in front of the terminal building, which not only guaranteed construction safety, but also met the requirements of urban traffic road reconstruction under complex environment, and achieved the goal of non-flight-suspension construction for terminal building renovation.
