摘要
乌海至玛沁公路(宁夏境)青铜峡至中卫段(A7标段)镇罗黄河特大桥采用钢-混组合梁连续梁桥建设。以此项目为背景,探讨大跨度钢箱梁制造技术的关键重难点及解决思路、L型超高分段运输及现场安装技术的关键重难点及解决思路。
Zhenluo Yellow River Bridge in Qingtongxia-Zhongwei Section(Bid A7)in Ningxia Border of Wuhai-Maqin Highway is a steel-concrete continuous composite girder bridge.Based on this project,the key points,difficulties and solutions of large-span steel box girder manufacturing technology,L-shaped ultra-high fragmental transportation and on-site installation technology are discussed.
