On November 30, the main span of the continuous girder group of the Lianjiang River Super Large Bridge on the Shantou-Shanwei High-speed Railway was successfully joined, which opened up the girder erection pass from Shantou Chaonan Section towards Shanwei and laid a solid foundation for subsequent construction.

The total length of the Lianjiang River Super Large Bridge is about 5.6 kilometers. The continuous girder group consists of five continuous girders, which is the most concentrated section of continuous girders on the Shantou-Shanwei High-speed Railway. These continuous girders respectively cross the Lianjiang River, the Provincial Highway S234, the up and down ramps of Haimen Toll Station, and Xinhua Avenue, etc. Through the dynamic optimization scheme, the construction party scientifically solved the construction technical problems, and efficiently and accurately realized the closure of the main span of the continuous girder group. In early December, the girder erecting crane will erect the girders from Xinhua Avenue towards Lianjiang River Super Large Bridge, and enter the river-crossing section in late December. It is expected to complete the girder erection of the Lianjiang River Super Large Bridge in February next year. While erecting the girders, the construction party will advance the bridge deck system process, and strive to enter the slag-free track construction phase in Chaonan section in the second half of next year.

汕汕铁路练江特大桥主跨合龙

11月30日，汕汕铁路练江特大桥连续梁群主跨顺利合龙，打通了汕头潮南段往汕尾方向的架梁通道，将为后续施工奠定坚实基础。

　　练江特大桥全长约5.6公里，由5座连续梁组成的连续梁群是汕汕铁路全线连续梁最集中的段落，分别跨越练江、S234省道、海门收费站上下行匝道、新华大道等。施工方通过动态优化方案，科学破解施工技术难题，高效、精准地实现了连续梁群主跨的合龙。。12月初，架梁机将从新华大道往练江特大桥方向架梁，12月下旬进入跨江段，预计明年2月份完成练江特大桥的架梁施工。架梁过程同步推进桥面系过程，力争明年下半年潮南段进入无渣轨道施工阶段。
