“一带一路”上的“超级工程”:京新高速临白段建成通车

2017-07-24 14:57:32   中国经济网

这是一条“超级天路”

除了自然环境带来的困阻,这里也有很多很多的难题,更为“超级工程”的称谓增添了分量。

一是难度大。中建二局土木公司标段内施工难度最大的是位于山区的神树沟大桥,这是京新项目临白段全线的重点控制性工程。在大桥刚开始施工的时候,就遇到了一个大难题。神树沟是内蒙古自治区范围内少见的明河,而且河床之下多是流沙。不能断流,不能污染环境,必须要保证下游用水,一个个“紧箍咒”套在头上,让打桩施工陷入僵局。想点子、搞论证,否决了一个又一个方案。“要不我们给无流沙桩孔和有流沙桩孔结成‘帮扶对子’呗,把无流沙桩孔挖深一些作为集水井,将有沙层的挖桩孔集中抽水倒过来,然后咱利用这点‘空窗期’把桩打下去呗!”实践是检验真理的唯一标准,项目通过实地试验,抽水后迅速开挖穿越沙层,并缩短每次护壁的高度,减少沙层孔壁的暴露时间,果然可以及时进行护壁混凝土灌注。就这样,桩基按时完成了,拔出了阻碍神树大桥施工的一颗大钉子。

二是战线长。在只有临时便道的55公里中来回穿梭,需要多少时间?我们常常走公路、上高速,很难体会这里的时间概念。建设者这样告诉我们:一开始,施工机械撒入荒无人烟的55公里,战线长、分布散,其实和“在飞机上看火柴盒”差不多。“那个时候,一旦设备出现故障,我们只能一路小跑着找个有信号的地方向项目部报告,再等到维修队到达后,时间早过去了大半天”,项目设备部负责人回忆到。工期经不起耽搁啊,为解决这一问题,中建二局土木公司为自有设备统一加装了GPS。每天,设备负责人坐在总部的大型设备远程控制室里,就可以清楚的了解每台设备的地理位置、运行状况、工作时间、怠速时间、燃油消耗、设备故障,维修保养等信息,并根据需要迅速传达下去,省下了宝贵时间。

三年合同工期,仅仅13个月的有效工期,但工程依然出色。时间就是这样一点一滴省出来的。

这是一条“幸福天路”

京新高速临白段的贯通,对国家意义重大,对阿盟人民来讲,更是一条“幸福天路”,它从根本上改善内蒙古阿拉善盟长期处于国家干线公路网死角和末梢的局面。

通车后,居住在这里的人,可以直接驱车上高速,向东,可以直达首都,向西,穿越甘肃,直至新疆,再也不用在狭窄的道路上绕行。
