摘要
S26入城段R-3标跨G15高速公路大跨度跨线钢箱梁施工中,通过优化钢箱梁分段方案及架设顺序,以及对吊装松钩时钢构件连接程度的合理化界定,提出大跨度钢箱梁一跨成桥的施工技术路线,做到跨中无支撑体系,降低了跨线施工对既有交通的影响,提高了工程效益。
The entry section of S26 R-3 standard across the G15 highway large span across the line of steel box girder construction, by optimizing the segmentation scheme, site and erection sequence, as well as the connection degree of rationalization of lifting loose hook ShiGang component definition, puts forward a large span steel box girder across a bridge construction technical route, do this without a support system, reduce the cross line construction influence on both the traffic, improve the benefit of engineering.
