“我们只研发填补空白的产品”

2017-08-23 08:32:38   中国青年网

前不久,记者随国资委“砥砺奋进新国企”采访团走进了位于湖南长沙的中国铁建重工集团,采访中记者获悉:中国将建设最先进的、完全自主研发的磁浮轨道试验线和生产线;而仅仅经过10年的发展,铁建重工已拥有全国最大的再制造产业基地,成为了全球领先的隧道施工智能装备整体解决方案和高端轨道设备提供商。

中国将建最先进的磁浮生产线

据悉,铁建重工将在长沙建设一条磁浮生产线。将于今年11月份动工,明年6月份建成。届时,中国最先进的、完全自主研发的磁浮轨道试验线和生产线。

磁浮是利用电磁体“同性相斥,异性相吸”的原理,让移动列车具有抗拒地心引力的能力,使车体完全脱离轨道,悬浮在轨道上面,贴地飞行。

国内首条投入运营的中低速磁浮线——长沙磁浮快线,也是目前全世界最长的中低速磁浮线路,由中国铁建旗下中铁第四勘察设计院集团有限公司设计,并代表中国铁建实施设计施工总包。

据了解,中国所拥有的上海磁浮示范运营线是世界唯一商业运营的高速磁浮列车线路,也是目前处于运营中的4条商业磁浮列车线路之一。另外3条均为中低速系统,分别是日本东部丘陵线、韩国仁川机场磁悬浮线以及中国长沙磁浮快线。

“我们建成后,将成为中国第3条磁浮机车生产线和第1条磁浮轨道生产线。”铁建重工首席专家王全生表示,在磁浮机车领域,承担生产线施工的铁建重工虽然算是个新兵,但如果未来轨道和机车的生产相匹配,上述生产线建成后每年将增加轨道120公里,增加机车60列。

铁建重工党委书记、董事长刘飞香透露,这条试验线全长2.5公里,是目前国内智能化程度最高的磁浮线路。“安装各种传感器,各种参数全部自动传输到实验室,工况、道岔、坡度等可以自动调节,智能检测程度很高,可以测试各种机型”。

2017年5月2日,中国科学技术部、交通运输部联合发布《“十三五”交通领域科技创新专项规划》,根据规划目标,力争2020年前实现磁浮交通系统技术完全自主化的技术能力。

提及中低速磁浮交通的优势,铁四院长沙磁浮线总体设计负责人靖仕元算了一笔账:地铁造价约5亿元至8亿元/公里,而中低速磁浮系统平均造价约2亿元/公里,仅相当于地铁价格的1/3~1/2。除了价格优势以外,中低速磁浮交通还有曲线半径小、爬坡能力强、噪音污染小等优势。
