超高位大跨度128m钢桁梁拼装及横移施工技术

The assemble and traverse technology of 128 meters long ultra high and long span steel truss in construction

以具体工程为背景,介绍并探讨了超高位跨既有线架设钢桁梁的临时支墩体系施工、滑道梁安装、钢桁梁高空拼装施工技术、钢桁梁横移施工技术、落梁施工技术以及超高位大跨度钢桁梁施工监测技术,以供参考。

Taking the practical project as the background, this paper introduced and discussed the temporary pier system construction, slide beam installation, steel truss beam high-altitude assembly construction technology, steel truss girder traversing construction technology, falling girder construction technology and ultra high large span steel truss girder monitoring technology of ultra high span existing railway erection steel truss girder, so as to provide some reference.
