Smooth transition of Jingjiu Railway Bridge on Jinshi Expressway

On the night of November 27, the main bridge of the separation flyover across Beijing Jiulong Railway on the Tianjin Shijiazhuang Expressway (from Tianjin Hebei boundary to Baoshi boundary) successfully turned. The whole process took 40 minutes, and the turning was accurate and in place. In order to ensure the safety of construction and the smooth transition of the bridge, the construction unit has formulated the special construction scheme for the transition of the main bridge of the separation flyover of Beijing Jiulong Railway, and organized an expert review meeting to review the special scheme in detail. In order to reduce the influence of bridge construction on railway operation, T-structure construction adopts the method of "building first, then transferring". After one-time transfer, no concrete pouring construction is needed above the railway line, so as to minimize the interference on railway traffic and reduce the construction safety risk. The overpass project of

Tianjin Shijiazhuang Expressway (from Tianjin Hebei boundary to Baoshi boundary) across Beijing Kowloon Railway is located in the south of donglingcheng village, Renqiu section of Tianjin Shijiazhuang expressway. It is one of the key control projects of Tianjin Shijiazhuang Expressway and the only transition bridge in the whole line. The successful turning construction of the bridge has laid a solid foundation for the smooth connection of Tianjin Shijiazhuang Expressway (section from Tianjin Hebei boundary to Baoshi boundary), and created favorable conditions for the timely opening of the whole line.
