特殊环境下某大型跨铁路钢筋混凝土组合结构通廊拆除工程的施工

Demolition Construction of a Large Railway-crossing Corridor of Steel-concrete Structure under Special Environment

栈桥式皮带机通廊较多采用爆破等破坏性拆除方式,但对于特殊环境下的大跨度通廊,破坏性拆除无法满足要求,针对钢结构混凝土大跨度通廊的结构特点,采用大型吊装设备,结合建筑物拆除相关工艺流程,总结出该类廊桥的吊拆工艺,同时通过科学测算,确保拆除设备与材料满足施工条件。

For trestle belt conveyer corridor, destructive demolition methods like blasting are largely adopted, but for large-span corridor under special environment, they cannot meet the requirements. Based on the structural features of steel structured concrete corridors with large span, the large hoist devices are applied with relevant demolition techniques, the hoist techniques for such kind of corridor trestles are summarized and through scientific calculation the demolition device and materials meet construction conditions.
