中新网广州11月6日电 (郭军 胡海焱)由国铁广州局深圳工程建设指挥部建设、中铁十五局集团承建的瑞梅铁路梅江特大桥跨漳龙段中跨5日顺利完成合龙,标志着梅江特大桥实现全桥合龙,标段重难点桥梁工程取得里程碑突破,为后续架梁铺轨、线路施工扫清关键障碍。
梅江特大桥为瑞梅铁路与龙龙铁路共桥合建三线桥,桥梁起止里程DK241+228.659~DK242+158.485,中心里程DK241+693.555,桥全长929.826米。本次合龙的16#墩至19#墩连续梁于DK242+029.5处上跨漳龙铁路,与既有铁路夹角68°,临近营业线,施工安全风险高、管控要求严。
为最大限度降低桥梁施工对既有铁路运营的扰动,保障既有线列车通行安全,项目部在连续梁作业范围内搭设专项防护棚架,筑牢既有线安全防护屏障。针对高空挂篮作业、预应力张拉、线形控制、涉铁天窗点施工等重难点,项目部组建专项技术专班,优化施工方案,全过程开展线形监测、应力监控,严格落实班前安全教育、挂篮走行验收、混凝土温控养护等举措,紧盯工序衔接,严控施工精度,平稳攻克跨既有铁路悬浇施工难题。
自开工以来,国铁广州局深圳工程建设指挥部统筹设计、监理、施工各参建单位,压实全过程建设管理。通过科学调配资源、动态优化施工组织,紧盯关键节点目标,统筹班组、机械配置,严格落实技术交底与现场过程管控。项目突击队、青年攻坚组扎根一线攻坚克难,先后攻克地质条件复杂、涉铁施工管控严、雨季施工影响大等难题,稳步推进墩身、现浇梁、挂篮悬浇等工序,顺利实现梅江特大桥全桥合龙。
梅江特大桥全桥合龙,是瑞梅铁路建设里程碑节点。这座瑞梅铁路与龙龙高铁合建的三线跨江控制性桥梁主体贯通,打通了全线架梁通道,攻克了大跨度跨江连续梁挂篮悬臂浇筑施工难题,为沿线老区交通提质、产业振兴、红色文旅发展提供关键支撑。

The 20.8-kilometer west extension of Provincial Highway 76 (Caotun-Fangyuan) was completed and opened to traffic at 12 noon on the 8th. It starts from the Fangyuan Interchange of Provincial Highway 61 in the west, connects Erlin and Puyan in the east, and connects to the existing Provincial Highway 76, connecting Provincial Highway 61, National Highway 1 and National Highway 3. The journey from Caotun to Fong Yuan is shortened from about 55 minutes to 35 minutes, saving about 20 minutes. Chief Executive Officer Zhuo Rongtai pointed out that this section directly connects Fangyuan Industrial Zone, Erlin Zhongke Base and Precision Park, improving the core capacity of the central precision smart park, and has disaster relief and medical referral functions. The project adopts a sponge road design, which combines flood detention and landscape green corridors, and integrates human-oriented environment and bicycle paths. The planning of this road section can be traced back to the "National Six-Year Economic Construction Plan" in 1991. In 2018, the extension project was approved by then Executive President Lai Ching-te and took about 20 years to complete.
During the National Day holiday, Zhejiang Communications Group continued to advance a number of major transportation projects. From cross-sea projects to mountainous highways and railways, tens of thousands of builders stick to the front line, taking advantage of the golden construction period in autumn to speed up project progress, and introduce smart construction technologies such as drones and smart equipment to help Zhejiang's road network construction and regional integrated development.

The second phase improvement project of Hualien County's Hua 64 Route Ruigang Highway was completed last month, and the Hualien County Government held an opening ceremony today. The project received a subsidy of 448 million yuan from the Highway Bureau of the Ministry of Transport. It will conduct in-depth renovation and widening of high-risk disaster-causing road sections. It is expected to improve the situation of collapse in rain, improve driving safety and promote local tourism.

During the National Day, the construction of the Gaoligongshan Tunnel, a controlled project of the Dali-Ruili Railway, continued to be difficult. More than 2,000 builders stayed deep in the earth, overcame complex geological problems, and made every effort to promote the project construction.
All blasting and excavation operations in the preliminary excavation area of the new channel of the Three Gorges Project were completed on September 30. As the leading part of the new Three Gorges Water Transport Channel, this project has accumulated construction experience through experiments, creating favorable conditions for the subsequent relocation of high-voltage transmission lines and the comprehensive construction of the main ship lock project.
The reconstruction and expansion project of the Panjin to Shenyang section of the Beijing-Harbin Expressway was officially launched on September 30. The project has a total length of 129.52 kilometers and a total investment of 13.9 billion yuan. The pilot section to be launched first will focus on verifying the width of wind-sand sand roadbed and soft ground treatment technology, aiming to improve traffic efficiency and support the comprehensive revitalization strategy of Northeast China.
