摘要
以郑州市南四环—郑少高速互通立交预制节段梁施工为依托,针对低净空小曲率半径立体交错的不同部位节段梁架设的技术难点进行了施工技术研究,提出了该项目经济适用的施工方法,并取得了较好的社会效益和经济效益。
Based on the precast segmental beam construction of Zhengzhou South Fourth Ring Road-Zhengzhou Shaoguan Expressway Interchange,this paper made construction technology research on the technical difficulties of segmental beams erection at different parts with three-dimensional staggered low clearance and small curvature radius,put forward the economic and applicable construction method of the project,and obtained good social and economic benefits.
