Cast-in-place frame construction method for underneath passing of existing operating railway
The invention relates to the technical field of frame bridge structure construction, and provides a cast-in-place frame structure construction method for underneath passing of an existing operating railway aiming at the condition that a construction section railway needs to be blocked for a long time when a frame bridge structure is poured below the existing railway, and the cast-in-place frame structure construction method comprises the following steps that S1, a plurality of supporting piles are constructed on roadbeds on the two sides of the construction section railway; s2, installing and constructing a cross beam; s3, longitudinal beam installation and construction; s4, connecting construction of the cross beams and the longitudinal beams; s5, connecting and constructing the cross beam and the construction section railway; s6, constructing a frame bridge structure; s7, the areas on the two sides of the frame bridge structure are backfilled to form a new roadbed; s8, line recovery construction is carried out; the method has the effect of reducing the influence of the frame bridge construction period on the normal operation of the construction section railway.
本申请涉及框架桥结构施工的技术领域，针对在既有铁路下方浇筑框架桥结构时需要长时间封锁施工段铁路的情况，提出了一种下穿既有运营铁路的现浇框构施工方法，包括以下步骤：S1：在施工段铁路两侧路基上施打若干支撑桩；S2：横梁安装施工；S3：纵梁安装施工；S4：横梁、纵梁连接施工；S5：横梁与施工段铁路连接施工；S6：框架桥结构施工；S7：在框架桥结构两侧区域进行回填以形成新路基；S8：线路恢复施工；本申请具有降低框架桥施工期间对施工段铁路正常运行的影响的效果。
