“坤巴c小洞”广湛高铁佛山坤巴c小洞段跨佛清从高速公路连续梁顺利合龙

  中新坤巴c小洞网佛山1月15日电 (郭军坤巴c小洞 王锐 黄诗伟)1月15日,随着最后一方混凝土入模,由广东省铁投集团所属广湛铁路公司投资建设、中国铁设集团EPC总承包、中铁二十五局承建的广湛高铁佛山段跨佛清从高速公路连续梁中跨顺利合龙,标志着广湛高铁2标最大跨度连续梁顺利完成施工,为后续桥面系及无砟轨道施工加速推进奠定了坚实基础。

  广湛高铁佛山特大桥总长18.58公里,是集斜拉桥、系杆拱桥、钢混刚构桥、转体连续梁、常规连续梁、预制简支梁、现浇简支梁等于一体的大型综合性桥梁,桥梁种类多、结构复杂、施工难度大,被称作“广湛高铁桥梁博物馆”。

  据中铁二十五局广湛项目总工程师郑伟介绍,此次合龙的连续梁位于佛山特大桥25号墩至28号墩之间,全长269.7米、桥面宽12.6米,设计为(66+136+66)米双线箱梁,梁体为单箱单室、变高度、变截面结构,采用挂篮悬浇法施工。连续梁上跨佛清从高速公路及务庄匝道出入口,紧邻村庄,施工区域车流量、人流量多,工序复杂且衔接紧密,安全挑战大,也是标段的重难点工程。

  广湛高铁是我国“八纵八横”高速铁路网、时速350公里沿海铁路客运大通道,也是连接粤港澳大湾区、海南自贸港、北部湾城市群的高速铁路大通道重要组成部分,建成通车后,将大幅缩短粤西地区与粤港澳大湾区的时空距离,广州中心城区至湛江中心城区可实现90分钟互达,极大改善粤西地区群众出行条件,助推粤西沿海地区阳江、茂名、湛江深度融入粤港澳大湾区联动发展。(完)
