成都地铁3号线三期高架段开始架梁

2017-09-17 07:41:38   中国青年网

本报讯 (记者 王眉灵)9月16日,伴随着大型架桥机的轰鸣声,400T预制箱梁在完成提升、平移等动作后准确地落在指定位置,成都地铁3号线三期高架桥段开始箱梁架设。

3号线三期工程在3号线一期基础上向北延伸至新都城区,线路全长约12公里,设车站9座,其中高架车站3座,高架及过渡段长近6公里,桥梁包含特殊孔跨共有112片预制箱梁,最大单片梁体积达161立方米,重418吨。该高架段主体工程位于蓉都大道主干道上,周边交通流量大,施工干扰大,制约因素多,安全风险高,是整个3号线三期的重难点控制工程。

根据工期进度,3号线三期预计2019年建成开通。
