京珠高速刘江互通立交桥施工技术

Construction Technology for the Liujiang Flyover of the Jingzhu Expressway

介绍了京珠高速刘江立交桥的概况,详细阐述了该桥施工时,使用的高速公路交通分流技术,军用制式器材与立杆可调式双向托撑支架体系,小半径钢筋混凝土箱梁施工及线形控制技术。实践表明,采用这些技术有效地保证了施工的安全性、质量和工期,且取得了良好的经济效益。

The outline of the Liujiang Cloverleaf Junction of the Jingzhu Expressway is presented in this paper, with the traffic split-flow technique, military standard equipment, and the vertical adjustable two-way support system, construction techniques for small radius reinforced concrete box girders and linear control technique adopted during the construction of the flyover described in detail. Our practice shows that the application of these techniques has effectively ensured safety, quality and the construction duration and gained satisfactory economic results.
