“18岁macbookpro中国”沪宁合高铁江18岁macbookpro中国苏段跨沪陕高速连续梁合龙

  中新18岁macbookpro中国网扬州11月26日电 18岁macbookpro中国(徐珊珊 崔佳明)11月26日凌晨,随着工作人员将最后一方混凝土浇筑入模,标志着由中国铁建大桥局施工的上海至南京至合肥高铁(简称“沪宁合高铁”)江苏段跨沪陕高速公路连续梁顺利合龙。

  据中国铁建大桥局沪宁XI标项目二分部副经理王德宇介绍,沪宁合高铁江苏段跨沪陕高速连续梁全长223.48米,桥梁宽12.6米,其中主梁自西北向东南斜跨沪陕高速公路,与高速公路斜交119.14度,是沪宁合高铁江苏段重难点工程。同时,该连续梁还是沪宁合高铁通泰扬特大桥的重要组成部分之一,通泰扬特大桥全长172.9公里,连接南通、泰州、扬州三地,比世界第一长桥——京沪高铁丹昆特大桥还长8公里。

  此次合龙的连续梁为双线预应力混凝土连续箱梁,箱梁共分59个节段,采用支架现浇、挂篮悬臂浇筑方式施工,具有安全风险高、精度要求高、施工技术难度大、周边环境复杂等特点。

  据了解,沪宁合高铁是沪渝蓉高铁的东段线路、国家“八纵八横”高速铁路网沿江高铁通道的重要组成部分,承担沿江通道主要路网客流、沿海及京沪通道部分直通上海客流的运输。该项目建成后,将在上海大都市圈、南京都市圈和合肥都市圈间建起一条快速新通道,对于优化沿长江地区铁路网布局、服务长江经济带协同发展,推动长三角高质量一体化发展等具有重要意义。(完)
