太原涧河转体立交桥施工技术

Construction technology for swing overpass of Jianhe Road in Taiyuan

在太原市涧河路立交桥跨越铁路石太线、石太客运专线转体桥施工中,采用若干关键技术来控制转体。通过对实际施工中转动体的结构设计、转盘的施工安装、转动体的平衡测试和转动控制等进行阐述,详细介绍了转体的控制过程。应用结果表明,关键控制技术的应用,保证了转体施工安全、有序的进行。

The Jianhe Road overpass of Taiyuan crosses the railway line and passenger line from Shijiazhuang to Taiyuan. The swing bridge construction adopted certain critical technologies to control the swing. This paper elaborates structural design of the rotating body, the construction and installation of turntable, the balance test and rotation control in the actual construction, and introduces the control process of swing. The application results show that the application of the control technique can guarantee an orderly and safe swing construction.
