大跨度工字钢承重支架在跨高速公路现浇箱梁中的应用

Application of Long-span I-steel Bearing Support in Crossing Cast-in-situ Box Beam of Expressway

通过大跨度工字钢承重支架在跨高速公路现浇箱梁施工的研究与应用,总结出了一套工字钢承重钢支架施工工艺,有效地解决了净空受限,大跨度跨高速公路,保证公路正常通行的现浇箱梁施工的支架搭设问题。

In this paper, through the research and application of large-span I-steel bearing support in the construction of crossing cast-in box beam of expressway, a set of I-steel bearing support construction technology is summarized effectively to solve the clearance limitation and to cross the expressway by long span, and to solve the support erection problem in the construction of cast-in-situ box beam for guaranteeing the highways under the normal traffic.
