中国铁建巩固主体业务 技术创新实现产业结构历史性升级

2017-09-17 08:36:38   中国经济网

党的十八大以来,在不断巩固提升主体业务的同时,中国铁建产业结构实现了历史性升级,产业结构日益优化,协同效应日益显现,创效能力日益提升

日前,中国铁建十八局集团承建的我国最大规模、世界罕见的岩堆隧道——新建田师府至桓仁铁路大前石岭隧道安全贯通,破解了世界性特别不良地质极高风险隧道施工难题。

这样的世界第一在中国铁建屡见不鲜。开发高原铁路建设成套技术,成功解决“高寒缺氧、多年冻土、生态脆弱”三大世界难题;建成路段相继诞生时速486.1千米的世界高铁运营线最高速、时速840千米的世界交会最高速;承建世界在建难度最大的海峡大桥、最大跨度客货共用高铁特大桥、最大跨度铁路拱桥……一个又一个“堡垒”被中国铁建攻克。

综合实力不断增强

中国第一条电气化铁路、第一条高原铁路、第一条盐湖铁路、第一条沙漠铁路、第一条重载铁路、第一条高速铁路……这诸多标志性的第一都出自中国最大的铁路设计和施工企业——中国铁建。

成立以来,中国铁建参与了国内所有大型铁路建设,设计、建设里程超过10万千米,在高原铁路、高速铁路、高寒铁路、山区铁路、复杂地质铁路以及现代铁路站房等领域拥有绝对优势,首先提出市域铁路等创新理念,始终领衔中国铁路建设。

5年来,中国铁建不断取得新成绩。

2012年12月,哈大高铁通车。这是世界首条穿越高寒地区的高速铁路,成功解决防冻胀路基、接触网融冰、道岔融雪3大国际公认技术难题。

2014年12月,兰新高铁通车。其中300余公里位于中国乃至世界铁路风灾最严重地区,一举创下7项世界之最。

2016年12月,沪昆高铁通车。这是中国东西向线路里程最长、经过省份最多的高铁,是世界跨度最大、地形起伏最大、地质结构最复杂的铁路。

5年来,中国铁建综合实力实现历史性跨越,坚持党的领导与企业发展深度融合,坚持党的建设与生产经营协同发力,主要经济指标全面翻番增长。

作为高铁建设的主力军,在我国已经建成的高速铁路中,中国铁建承担了超过50%以上的勘察设计任务,承担了超过45%以上的建设任务。

原创智造填补空白

5年来,在不断巩固提升主体业务的同时,中国铁建的产业结构也实现了历史性升级。通过坚持战略引领,加强改革创新、加速资源整合、加快转型升级,产业结构日益优化、协同效应日益显现、创效能力日益提升。
