中企“钟表级”施工 承建巴西科考站

9月,随着中国企业预制施工阶段结束并完成预拼装验收,巴西费拉兹司令南极科考站重建所需设备和材料将从上海港装船,运往南极乔治王岛组装。作为中国企业承建的首个外国南极科考站,因大火焚毁的费拉兹站即将“重生”,成为中巴这两个金砖国家的合作亮点。

中国南极长城站、中山站与昆仑站总设计师、清华大学建筑设计研究院极地建筑研究中心主任张翼说,2008年,中国在南极冰盖最高点、海拔超过4000米的冰穹A地区建设中国首个南极内陆考察站——昆仑站。当时,昆仑站与德国诺伊迈尔Ⅲ科考站不约而同首次采用一种新的“全装配式”建站模式,即内部是预制的集装箱功能模块,外层是现场安装的保温板,全部模块运至南极组装。

中国在南极成功的实践经验坚定了其他国家寻求合作的信心,南美多国相继抛来“橄榄枝”,寻求中方帮助建站。2015年5月,中国电子进出口总公司击败多个国际竞标方,成功中标费拉兹站重建工程。

费拉兹站联合设计方、负责结构和设备专业设计的葡萄牙公司AFAconsult首席执行官鲁伊·富尔塔多说,该站的设计如同精密的瑞士钟表制造,所有部件和系统必须要以高度精确的水平建造,才能和谐运作、发挥功能。

中国电子进出口总公司费拉兹站建设项目组经理曹虹说,鉴于设计的高精度,费拉兹站建设已经不是钢结构要求水平,而是机械加工精度要求,整个项目采用了先进的全装配式施工工艺和建筑信息模型技术。

南极只有4个月的施工窗口,所有时间都要用来组装,所有一切都要提前准备和考虑。预制阶段哪怕几毫米误差的小瑕疵,也可能造成组装中的大麻烦。为实现现场100%的顺利装配,中国企业必须拿出“钟表级”的建造和施工。
