智慧化建设技术是重要助力。在施工难度较大工程之一——跨沙河特大桥的建设中,项目方采用全自动智能张 拉、压浆设备,梁体智能喷淋养护系统等各种实用技术,不仅减少了人力,还有效提升了标准化作业水平。 □四川日报全媒体记者 寇敏芳/文 华小峰/图 "开工喽!"2月24日,成都站站房外约500米的一处工地,响起了一阵吆喝声。然而,记者环顾四周,偌大的工地 只有零星10余名工人,施工点位也仅有一处钻探打桩机在作业,全然没有想象中节后复工热火朝天的景象。 "别看我们人少,进度却一点没有落下。"中铁八局集团有限公司成都站扩能改造工程指挥部副总工程师何雨居 说,凭借高效的施工组织调度和先进的智慧建造技术,项目建设实现"人少也能出快活"。 "人少活快"背后 有智慧化建设技术助力 成都站俗称"火车北站",是新中国第一条自主建设的铁路——成渝铁路的起始站。为满足成渝中线高铁建设、市 域铁路公交化改造建设等需要,2022年10月,成都站正式停运并启动扩能改造。 记者所在的建设现场,就是成渝中线高铁进出站的最后一段。记者在现场看到,9条铁路线在约50米宽的范围内一 字排开。在长约1.2公里的区间里,铁路线两侧不仅有居民区,还要跨越沙河以 ...
