借力资本市场 中国中铁十年营收扩大近三倍

2017-09-04 07:35:52   中国经济网

今年上半年,中铁工业实现净利润6.47亿元,同比增长2.64%。中铁工业表示,上半年公司承担了世界最长跨海大桥港珠澳大桥建造中的22万吨钢结构制造工程,已有25台盾构设备出口到马来西亚、新加坡、黎巴嫩、以色列、印度等9个国家。

于腾群介绍,中国中铁“混改”工作也有新进展,公司下属企业中铁工程设计咨询集团有限公司(间称“中铁设计咨询”)作为国资委首批员工持股试点,日前以增资扩股方式完成了员工持股及同步混合所有制改革,引入新华联、比亚迪两家民营企业战略投资者。下一步,混合所有制改革带来的协同效应会逐步显现。

创新助力中国高铁建设

中国中铁(包括其前身)参与了国内所有主要铁路的建设,先后参与建设的中国铁路占全国铁路总里程的三分之二以上。于腾群介绍,中国中铁上市以来的10年,适逢中国高速铁路快速发展的阶段,从早期的京沪高铁、武广高铁、哈大高铁,到近期的京张高铁、沪昆高铁等重点高铁项目建设,中国中铁无一缺席,越难啃的工程“硬骨头”背后总有中国中铁的创造性努力。

京北的八达岭长城,游人如织,他们可能不知道脚下正有一条铁路在紧张施工。两年以后,北京的游客乘坐京张高铁30分钟就可以到达八达岭长城。中国中铁相关工程负责人介绍,京张高铁项目中,下穿八达岭长城的隧道和八达岭长城站是这条铁路建设的难点工程。新八达岭隧道一处并行水关长城,两次下穿八达岭长城,而八达岭长城站建成后将是目前世界埋深最大的高速铁路地下站,最深处达地下102米。

上述负责人谈到,中国中铁对施工进行了多项创新,如在建下穿长城等文物的隧道时,采用电子雷管减震爆破施工技术;在车站地下工程洞室密集段,采用电子雷管微损伤精准控制爆破技术;在大断面过渡段,采用多种隧道施工技术集一体的开挖掘进工法等,从而将对环境、文物的负面影响降到最小,并保证工程质量和进度。

京张铁路只是一个缩影。在我国从无到有打造“四纵四横”高铁网的进程中,作为“开路先锋”的中国中铁,始终以创新领衔国家工程的技术担当。

哈大铁路北起哈尔滨,南至大连,是世界上纬度最高的高速铁路,道路施工要克服冻土以及季节性温差等困难。为了满足高铁运营时速对质量的高精度要求,中国中铁相关工程局开展了寒冷地区无砟轨道施工技术等多项科研课题攻关,技术成果在全线运用推广,从而在使用灌板施工时中线偏移能够控制在1毫米以内,最大限度保证了精度要求。
