9年10万人建1条铁路 今天这条铁路将全线通车

2017-09-29 09:51:21   中国青年网

9年建一路自主创新攻坚克难

兰渝铁路是我国地质条件最复杂的山区长大干线铁路之一,也是一条施工难度极大、风险极高的铁路。

兰渝铁路是我国在建地质条件最复杂的山区长大干线铁路,穿越区域性大断裂10条、大断层87条,被称为“地质博物馆”。历经9年,十万名建设大军探索创新,攻克了一系列世界级难题,取得一大批科技创新成果。

全长28236米的西秦岭隧道是兰渝铁路全线最长的隧道,隧道地质情况极其复杂,多次穿越断层带,隧道最大埋深1400m。

专家给出的评价是“这种长达隧道的施工风险大、施工难度更大,地质复杂,容易岩爆。”不过还是被我们的铁路建设者们搞定了。

真正的高难度是兰渝铁路卡脖子工程---胡麻岭隧道,2017年6月19日早上10点30分贯通,只是一条隧道而已,为何如此轰动?原来打这条隧道遇到了“第三系富水粉细砂岩”这一罕见的世界性难题,其中一段短短的173米隧道,前后打了整整6年,平均下来每天还不到8厘米。

其实,全长13公里多的隧道,前两年就修到了只剩163米,可其后发生溜塌、突涌,让隧道施工陷入停滞。面对胡麻岭隧道这一罕见的世界性难题,国内外几十批次顶级专家都曾前来会诊,但都没有进展。连在铁路隧道施工中享有盛誉的德国专家都没成功,撤离时评价“不可能在这种地层中打隧道”,而中国铁路建设者在不懈努力下愣是啃下了这块“硬骨头”。

兰渝连接数十贫困县打造“脱贫路”

兰渝铁路经过的22个市县区中,有13个国家扶贫重点县、4个省级扶贫重点县。兰渝铁路打通的不仅是出山的道路,更是扶贫之路。

兰渝铁路覆盖的区域盛产花椒、核桃、中药材、木耳、橄榄油等经济农作物。但是由于交通不畅,运输成本高,很多高产经济作物无法吸引区域外客户订货。当地百姓守着致富的资源,却还不得不辗转到外地打工。

铁路运输直接降低了物流成本,甘肃的陇南,马坝村到附近的市场集散地,陆路运输的成本是1500元/吨。铁路运输的成本下降到400元/吨,运输成本下降了75%。很多去外地打工的乡亲们也陆续回到家乡,重新搞起了经济作物种植。

铁路开通了,农民看到了富裕的希望,有些陇南特色农产品电商企业干脆直接在这里落了户。靠山吃山靠水吃水,靠着陇南这个经济作物生产基地,直接做起了全世界的生意。
