摘要
结合实例主要介绍了多孔框架顶进桥纵横梁组合3-5-3吊轨的线路加固技术,对其施工工法进行了简单的阐述,纵横梁与3-5-3吊轨加固方法有着安全稳固、不影响行车的特点,因而在多孔框架顶进桥的线路加固上有很好的应用。
Combining with the practice,line reinforcement technology of girders and combination overhead rail of 3- 5-3 for multihole frame jacking bridge is introduced,the construction method is also showed. This reinforcement technology has characteristics of safety and stable which be used widely in line reinforcement of multihole frame jacking bridge.
