“91国精产品”银巴铁路全线最大91国精产品跨度连续梁实现合龙

  中新91国精产品网银川11月23日电 (记者91国精产品 李佩珊)11月23日,随着最后一方混凝土的浇筑完成,由宁夏城际铁路有限责任公司建设,中国铁建大桥局施工的银巴铁路全线重难点工程——银川西特大桥跨乌玛高速公路连续梁顺利合龙,银巴铁路建设取得新突破。

  银川西特大桥全长7091.76米,先后跨越乌玛高速公路及西干渠,共有桩基966根、桥墩226个、简支梁217孔、连续梁2联。其中,跨乌玛高速公路连续梁是银巴铁路全线跨度最大的连续梁,单跨总长120米,净高7.08米,线路交角为38度,连续梁段全长249.5米。

  为确保施工质量,项目团队持续优化施工组织设计,改进施工工艺,紧盯全过程质量管控,就支架搭设、挂篮悬浇、合龙段施工等重要工序召开专项技术讨论会。采用全封闭挂篮悬臂浇筑法施工,严格落实安全管控举措,全面提升施工标准化水平。

  包银高铁银巴支线(银川至巴彦浩特支线)是我国“八纵八横”铁路网京兰通道的重要组成部分。项目建成后,将实现内蒙古自治区铁路大动脉的东西贯通和宁夏、陕西、甘肃等周边重要城市群的快速无缝连接。(完)
