不中断车站运营情况下的大型构件吊装安全技术研究

Study on the Safe Hoisting Techniques for the Large Component under Traffic Flow

无站台柱雨棚钢管桁架建筑位于火车站站台上方,由于施工期间火车站必须维持正常的运营,并且要确保列车运营安全和旅客及施工人员的人身安全,给无柱雨棚施工带来了相当大的难度。经过对无柱雨棚结构和站场作业环境的细致分析,摸索出一整套不中断车站运营情况下大型构件的吊装技术,对同类型工程的施工具有一定的指导价值。

The pipe truss of the weather shed is constructed above the railway station platform and it is quite difficult for its construction, as the normal flow of the railway and safety of passengers and construction workers should all be guaranteed. Through the detailed analysis of the weather shed structure and of the construction surroundings, a set of safe hoisting techniques for the large component is brought out, which can be of guidance value for the similar engineering.
