跨座式单轨交通PC轨道梁预制技术研究及应用

Research and Application of PC Guidebeam Prefabrication Technologyfor Straddle Monorail Transit

摘要:

跨座式单轨PC轨道梁为“梁轨合一”结构，线路的平、竖曲线、横向超高以及预拱均在一次浇筑的梁体上实现，其线形及精度直接决定着列车行驶的舒适性。芜湖市单轨项目在国内无成熟经验可借鉴的情况下创新施工方案，设置直曲线梁专用生产线、研发智能三维可调节模板、研究线形动态控制方法，得以成功制造出高标准的轨道梁，并总结出成熟的工艺及方法，具有推广价值。

Abstract:

The PC track beam of straddle monorail is a structure of beam and rail integration. The horizontal and vertical curves, transverse superelevation and pre arch are realized on the one-time pouring beam body. Its alignment and accuracy directly determine the comfort of the running train. In the case of lack of mature experience in China for Wuhu's monorail project, the construction scheme is innovated, the special production line for straight curved beam was set up, intelligent three-dimensional adjustable formwork was developed, linear dynamic control method was studied, and the high-standard track beam was successfully manufactured. The summarized mature technology and method is valuable for popularization.
