大西客运专线晋陕黄河大桥空心高墩翻模施工技术

Turning Mould Technology Adopted in Fabricating High Hollow Piers of Yellow River Bridge on Datong-Xi'an PDL

客运专线铁路空心高墩采用墩内搭设脚手架和模板外挂工作平台的方法施工是安全高效、经济合理的。为此,以大西铁路客运专线晋陕黄河特大桥施工为研究对象,探讨和摸索高速铁路空心高墩施工方法,并深入研究其安全可行性、经济性、高效性,以提高施工效率,减少施工投入。

Technology of fabricating high hollow piers with housed-in scaffold and mould and outside hanging working platform is safe,cost-effective and rational.The paper explores construction methods for high hollow piers of Yellow River bridge on Datong-Xi＇an PDL,studies in depth their safe-adaptability,economy and efficiency so as to enhance construction efficiency and reduce construction cost.
