立交桥箱梁支架施工方法的研究

The Construction Scheme for Box Girder Frame of Overpass

通过对郑州市京广路—沙口路快速通道施工中建设路立交桥箱梁支架施工方案的比较,结合工程具体情况,分析了常规施工方法的优缺点,最终提出了适于该工程特点的施工方案,在立交桥施工中采取满堂支架和门式支架相结合的支撑方式,顺利完成了立交桥的施工,取得了良好的施工效果.

By the comparison of the construction programs for box girder frames in the Jianshe road overpass inJingguang-Shakou expressway of Zhengzhou were researched in detail. According to the specific circumstances of the project, the advantage and disadvantage of traditional construction methods were analyzed. The construction scheme fit for the project was put forward. The support method of the combination of full frame and gantry frame was used in the construction of the overpass, which bring about a successful construction and reference for the similar projects.
