“沉迷于黑人的人妻米仓穗香”广东连山至广沉迷于黑人的人妻米仓穗香西贺州公路黄洞大宁河大桥合龙

  中新沉迷于黑人的人妻米仓穗香网贺州11月1日电(覃岑往 沉迷于黑人的人妻米仓穗香信亦凡)10月31日,广东连山至广西贺州公路(广西段)融资+工程总承包№4标段(简称连贺4标)关键控制性工程——黄洞大宁河大桥顺利合龙,全面进入桥面铺装施工阶段。

  上述项目由广西交通投资集团有限公司投资建设,广西路建工程集团有限公司承建。大桥施工创新采用边中跨同步合龙施工工艺,这是广西连续刚构桥建设的首例,也是全国首次运用智能调重系统实现连续刚构桥边中跨同步合龙。

  黄洞大宁河大桥全长627米,主跨为145米连续刚构梁桥,主墩为空心薄壁墩,全桥共有4个边跨现浇段,4个边跨合龙段,2个中跨合龙段,桥梁最高处距离河面高差约为90米。桥址为低山地貌,地形起伏较大,桥梁中央穿越河谷处沟谷陡峭,施工技术要求高、安全风险系数大。

  为打造内实外美的工程,项目建设团队聚焦提升智能建造水平,运用智能调重系统进行边中跨同步合龙施工,将大桥合龙精度有效控制在7毫米以内。

  大桥合龙段混凝土浇筑完成后,项目建设团队通过内箱智能养生、外箱全过程养护,确保梁体温差保持相对恒定状态及相对零外部应力状态,提高混凝土浇筑质量。

  新工艺不仅有力保障了大桥高精度合龙,也为大桥建设节省了10天工期。此外,项目建设团队进一步优化施工方案,适当增加挂篮节段悬臂浇筑长度,将挂篮节段由原设计的18节优化至16节,有效降低挂篮节段施工周期,节约工期20天。

  截至目前,连贺4标路基工程已全部完成路床交验,附属防排水工程完成率达90%;3座隧道均已全部贯通,正在施作隧道附属工程施工;6座大桥均已全幅贯通,正协同推进剩余桥面系及附属工程施工进度。

  连山至贺州公路(广西段)是《广西高速公路网规划(2018-2030年)》“横3”线贺州(粤桂界)至西林(滇桂界)高速公路的重要路段。项目建成通车后将进一步完善广西与广东高速互联网络,推动粤北及广西贺州旅游业的发展,促进粤桂两省区经济互联互通、协同发展。(完)
