Railway D-shaped auxiliary beam pile-free foundation line reinforcement construction method
The invention relates to the technical field of railway line reinforcement, in particular to a railway D-shaped auxiliary beam line reinforcement method, in particular to a railway D-shaped auxiliary beam pile-free foundation line reinforcement construction method, and aims at solving the problem that when a traditional D-shaped auxiliary beam is used for railway line reinforcement construction, hole digging piles are difficult to implement. The railway D-shaped auxiliary beam pile-free foundation line reinforcement construction method specifically comprises the steps of constructing a temporary buttress of a D-shaped auxiliary beam, installing the D-shaped auxiliary beam, constructing a strip-shaped foundation, longitudinally moving the D-shaped auxiliary beam to the strip-shaped foundation, excavating soil and jacking a frame bridge, jacking the frame bridge in place, dismantling the D-shaped auxiliary beam and recovering the line. According to the construction method, a hole digging pile is replaced by the strip-shaped foundation, and construction is carried out under the condition of not interrupting railway driving, so that the safety risk is greatly reduced, and safe construction is guaranteed.
本发明涉及铁路线路加固技术领域，特别涉及铁路D型便梁线路加固方法，具体为铁路D型便梁无桩基础线路加固施工方法，为了解决传统的D型便梁进行铁路线路加固施工时，挖孔桩实施困难的问题，故提供了一种铁路D型便梁无桩基础线路加固施工方法，具体为施工D型便梁临时支墩‑安装D型便梁‑条形基础施工‑D型便梁纵移到条形基础上‑挖土顶进框架桥‑框架桥顶进就位‑拆除D型便梁、恢复线路。本工法施工由条形基础替代挖孔桩，在不中断铁路行车条件下施工，故大幅度降低安全风险，保证安全施工。
