在进行框架桥顶进施工的时候,对于既有铁路架空加固是一个关键问题,如果施工质量不过关必将影响铁路的正常运转。本文结合某铁路框架桥顶进施工,详细介绍了在不中断既有铁路正常运营行车的背景下,使用吊轨、纵梁、横梁等多种措施相结合的方法,来对顶进施工时既有铁路架空进行加固的施工技术。实践证明该种方法时行之有效的,成功的解决了实际问题。
During the construction of frame bridge, it is a key issue for existing railway overhead reinforcement. However, if the construction quality is not good enough, the normal operation of the railway will be affected. In this paper, a railway frame bridge jacking construction, introduced in detail without interrupting the normal operation of existing railways in the context of the use of hanging rails, stringers, beams and other measures combined method to jacking construction both Overhead rail reinforcement construction technology. Practice has proved that this method is effective and successfully solved the practical problems.
