Construction method of large-span railway bearing rail beam crossing existing subway station
The invention relates to the technical field of railway engineering construction, and particularly discloses a construction method of a large-span railway bearing rail beam crossing an existing subway station, which comprises the following steps: S1, preparation before construction: carrying out three-dimensional simulation by using a BIM (Building Information Modeling) technology, and determining an accurate position relationship between a newly-built railway bearing rail beam and the subway station; s2, a construction process; and S3, inspection and maintenance after construction. According to the method, a construction scheme is determined through BIM technology three-dimensional simulation before construction; in the construction process, a steel pipe column and a double-layer bailey truss supporting system are adopted, the combined construction technology of a rotary drilling rig and an ultra-long pile casing is combined, and the construction technology of a skip method is adopted, so that the supporting difficulty of a large-span rail bearing beam and the construction difficulty of inclined rock surface hole forming are effectively solved, the construction precision and the engineering quality are improved, and the construction cost is reduced. And on the premise that safe operation of the existing subway station is guaranteed, efficient and safe construction is achieved, and remarkable economic benefits and social benefits are achieved.
本发明涉及铁路工程施工技术领域，具体公开了一种跨越既有地铁车站的大跨度铁路承轨梁的施工方法，包括以下步骤：S1、施工前准备：使用BIM技术进行三维模拟，确定新建铁路承轨梁与地铁车站之间的精确位置关系；S2、施工过程；S3、施工后检查与维护。本发明通过施工前的BIM技术三维模拟，确立了施工方案；在施工过程中，采用钢管柱和双层贝雷架支撑体系，结合旋挖钻机和超长护筒组合施工技术，以及跳仓法施工技术，有效解决了大跨度承轨梁的支撑难题和斜岩面成孔的施工难点，本发明不仅提高了施工精度和工程质量，而且在保障既有地铁车站安全运营的前提下，实现了高效、安全的施工，具有显著的经济效益和社会效益。
