A |     　　广州8月26日电 (郭军 吴义五 刘福强)8月25日，深江铁路10标中山站南东联络线上跨广珠城际特大桥门式墩钢盖梁完成吊装焊接作业，为后续简支梁架设、桥面系施工筑牢基础。　　中山站南东联络线上跨广珠城际特大桥由中铁广州工程局集团承建。    (ECNS) -- The Horgos Port in northwest China’s Xinjiang Uygur Autonomous Region has handled more than 6,000 China-Europe and China-Central Asia freight trains so far in 2025, transporting over 10 million metric tons of cargo.    This milestone was reached as a train loaded with engineering machinery, auto parts and home appliances departed the port. To boost efficiency, Horgos Customs and railway operators have launched a “smart port plus rapid local customs clearance” system for real-time data sharing. Supported by intelligent image inspection and pre-arrival scanning technologies, trains are cleared on arrival, cutting overall customs clearance time by over 50%.    The routes operating from Horgos now cover 91 lines reaching 18 countries and regions, handling more than 200 types of cargo. Combined freight volume across Xinjiang’s two major land gateways, Horgos and Alashankou, has surpassed 11,000 trains, marking a 5.9% year-on-year growth.    (By Intern Lin Qiaochu, Zhang Dongfang)                    。

B | 项目位于中山市火炬开发区，桥梁上跨运营中的广珠城际电气化铁路。本次施工的24#、25#、26#门式墩为钢混组合门式墩结构，钢盖梁为箱形钢结构，单榀整体吊装最大重量达132.76吨，吊装作业属于营业线Ⅱ级高风险施工，全部作业只能在夜间铁路封锁天窗点(00:30-04:30)内完成，作业窗口期短，吊装区域紧邻高铁接触网，高空对位容错空间极小，防异物侵限、防高空坠物、设备防倾覆管控压力巨大，涉铁多方协调组织难度大。　　项目团队超前谋划，联合广州南高铁工务段、广州供电段等单位编制专项营业线施工方案，组织专家论证评审；选用500吨履带吊超起工况开展吊装作业，对吊机地基采用水泥搅拌桩进行加固处理；钢盖梁采用工厂分段制造、现场胎架拼装焊接，吊装前完整开展空载、静载、动载全流程模拟试吊，反复推演吊装回转、落位、焊接、撤场全工序，细化到人、精确到分钟。在各方协同联动下，三榀钢盖梁依次就位，整套工序在天窗点内安全有序完成，实现“零侵限、零隐患”目标。深江铁路上跨广珠城际特大桥钢盖梁吊装完成。中铁广州工程局集团 供图　　深江铁路是国家“八纵八横”高铁网沿海通道的重要组成部分，正线全长116.12公里。

C | 项目建成后将串联深圳、东莞、广州、中山、江门5座粤港澳大湾区核心城市，实现深圳前海与广州南沙自贸片区半小时互联互通，深圳与江门1小时直达，进一步织密大湾区高铁网络，为区域资源优化配置、产业协同发展与高质量发展注入新动力。
