3月15日,上游新闻·重庆晨报记者从中铁建重庆投资整体双合高速公路公司得悉,由中国铁建大年夜桥局承建的合璧津高速公路油溪长江大年夜桥主缆“基准索”从南岸成功牵引过江,正式开启了“悬索桥”中的“悬索”施工。

大年夜桥将进行上部布局施工

下战书3时38分,在距离地面最高170多米的猫道上,施工人员一直地来回穿梭,进行基准索股牵引。

据体会,油溪长江大年夜桥上下贱共两根主缆,总重量达4166吨,单根主缆由112股索股构成,每股索股重约18.59吨,由91根直径为5毫米的镀锌高强钢丝构成。

“主缆作为大年夜桥的主要受力构件,是桥梁上部布局施工节制的关头环节,被誉为悬索桥的‘脊梁’,悬链线外形的主缆,是悬索桥上部布局的主要承重布局,是以,主缆架设是悬索桥上部布局施工的关头环节。”

相干负责人介绍,“基准索”作为主缆可否保质保量架举措措施工的根本和关头工序显得稀奇主要。主缆起首架设“基准索”,接纳绝对高程定位,作为一般索股架设的基准,“基准索”的精度决意主缆究竟线形的精度,调索误差上下贱相对高差要节制在毫米级,是以,严格节制其线形精度是保障主缆架设质量的关头。

合璧津高速公路油溪长江大年夜桥主跨760米,主塔高172.5米,相当于60层楼高。主缆架设在大年夜桥施工历程当中起着承前启后的感化,它是桥梁的下部布局施工转为上部布局施工的一个主要环节。“基准索”的成功牵引架设,标记住油溪长江大年夜桥所有转为上部布局施工。

土建工程形象进度已过半

今朝,合璧津高速公路已完成土建工程形象进度为58.2%,个中路基工程完成58.6%,桥梁工程完成42.7%,涵洞工程完成87.2%,2座地道已所有贯通,路面标段已进场。

该线路起于与三环铜合高速交叉构成的城南关键互通,经合川十塘镇,在铜梁区旧县镇、蒲吕镇穿九峰山至璧山区,经璧山八塘镇、七塘镇、大年夜路镇、福禄镇、河畔镇、大年夜兴镇、正兴镇、丁家镇至江津区,经德感镇、油溪镇设油溪长江特大年夜桥逾越长江至龙华镇、慈云镇至终点接江习高速。

项目建成通车后,全线削减绕行距离长达65千米,将串联起成渝高速、成渝高速扩容工程、渝蓉高速、渝遂高速等多条射线高速公路,在重庆绕城高速和三环高速之间构成新的毗邻线,将有用鼓动成渝地区双城经济圈交通扶植互联互通。
