套装导梁式箱梁运架设备的研制与应用

RESEARCH AND APPLICATION OF CARRYING AND ERECTING DEVICE FOR SHELL GUIDE GIRDER TYPE BOX GIRDER

我国铁路快速客运专线由于其设计时速高,要求乘坐舒适,采用了大半径曲线,故其桥梁所占比重大,梁型复杂,为满足施工需要,我们设计、研制了本文所述的运架设备,它在适用性、安全性、稳定性、经济性等方面都取得了突出的进展,相信它的试制成功和投入使用,必将带来良好的社会和经济效益。

Large radius curve is adopted on high-speed passenger dedicated line of Chinese Railway owing to the requirements for high design speed and good comfortableness of the line. Therefore, there are lots of bridges with different types on the line. The carrying and erecting device for shell guide girder type box girder was design and developed in order to meet construction requirements. The device has made great progresses in usability, safety, stability and economic characters and the good social and economic benefits can be gained by usage of the device.
