Pushing type construction method for passenger platform bridge in railway operation section
The invention discloses a railway operation section passenger platform bridge incremental launching type construction method which specifically comprises the following steps that S1, according to the length of platform bridge sections, an equal-height steel truss girder splicing platform is erected on the outer side of a platform, and steel box girders are prefabricated and spliced in a segmented mode; s2, a pushing auxiliary temporary support is arranged on one side of the platform; s3, hydraulic jacks are symmetrically arranged at the tail end of the bridge; the invention relates to the technical field of platform bridge construction. According to the pushing type construction method for the passenger platform bridge in the railway operation section, the construction organization is improved, the deformed steel bar connector is guided and replaced while the sliding block is guided and replaced every time, it is ensured that the deformed steel bar connector passes through the next section, in this way, the work of guiding and replacing the finish rolling deformed steel bar connector can be completed within the time of guiding and replacing the sliding block, time does not need to be occupied, and time is saved for construction blocking. Meanwhile, in the pushing process, the phenomenon of clamping stagnation is avoided when the finish rolling deformed steel bar connector passes through the sliding block channel at any time, the pushing safety is ensured, the influence on a railway line is small, and remarkable social benefits are achieved.
本发明公开了一种铁路运营段旅客天桥顶推式施工方法，具体包括以下步骤：S1、根据天桥节段长度，在站台外侧搭设等高钢桁梁拼装平台，分段预制、拼装钢箱梁；S2、在站台的一侧设置推动辅助临时支架；S3、在桥尾端对称设置液压千斤顶；本发明涉及天桥施工技术领域。该铁路运营段旅客天桥顶推式施工方法，通过改进施工组织，在每次导换滑块的同时将螺纹钢接头导换好，确保通过下一个节间，这样导换精轧螺纹钢接头的工作就可以在导换滑块的时间内完成，不用再多占用时间，为封锁施工节省了时间。同时，在顶推过程中随时关注精轧螺纹钢接头通过滑块通道时不发生卡滞现象，确保了顶推安全，且对铁路线路影响较小，具有显著的社会效益。
