Recently, after 6 hours of continuous construction, the first main pier of continuous beam of G347 super bridge of Jiangbei Port Railway special line in Tongling Port was successfully poured。

　 The continuous beam of G347 super bridge is a control project of all bridge joints。The construction is close to National Highway G347, and the traffic flow is large and the construction safety pressure is large. The smooth pouring of the pier has laid a solid foundation for the development of the nodal project。This continuous beam construction using hanging basket cantilever casting process, the construction of 43# main pier using a casting molding process, pier structure size 7*3. 2*8.5 meters, total concrete 180 cubic meters, rebar 8. 5吨。

　 In order to ensure the smooth pouring of the pier, the construction unit of China Railway 16th Bureau held several technical meetings to rationally optimize the pouring construction plan, from the reinforcement binding, formwork assembly, embedded parts installation, concrete pouring and site safety protection and other processes to do the best connection, and passed the "first piece" acceptance。During the pouring process, the experimenter conducted the slump test of the concrete, which all met the design requirements and relevant specifications and standards. In addition, the retention work of the concrete specimens was timely done to prepare for the subsequent testing of the compressive strength of the concrete, so as to ensure the safety and quality control of the pouring process。
