城市高架桥大型钢箱梁拆除施工

City Viaduct Demolition Construction of Large Steel Box Girder

目前轨道交通工程处在一个飞速发展的阶段,在施工的过程中,会经常遇到与原有交通设施的冲突。某城市地铁与立交桥间的盾构区间存在冲突,需拆除全桥,待地铁车站建成后原位恢复立交桥。通过介绍前期施工准备,钢和架的切割及吊装工作,对钢箱梁的拆除施工要点进行简要分析。

With the development of China's city development,construction and application of wide viaduct,and city track traffic engineering is more and more prominent,the current rail traffic engineering is in a stage of rapid development,in the construction process,often encounter conflicts with existing traffic facilities,this thesis takes the shield the conflict between a city subway interval and overpass the demolition construction points of steel box girder with brief analysis.
