铁建重工掘进机伊朗大显身手

2017-08-09 06:37:26   中国青年网

湖南日报8月8日讯(记者 曹娴 通讯员 胡清)伊朗当地时间8月6日清晨,由中国铁建重工集团自主研制的全断面双护盾岩石隧道掘进机(TBM),在伊朗西南部引水隧洞工程顺利始发,这是该集团TBM首次出口海外市场并在工程中应用。

设备施工现场位于伊朗伊拉姆省的大山中,该地区为丘陵地带,地质情况复杂多变。施工隧道全长12公里,整体地层为泥岩和砂岩,其中隧道有70%以上为泥岩,岩石最大单轴饱和抗压强度为50兆帕。形象地说,就是这种岩石“又软又硬”,抗压强度尤其大,TBM长时间在泥岩地层掘进极易造成刀盘被糊;加之当地夏季处于高气温、高水温环境,白天最高气温近60摄氏度,夜间最低气温近40摄氏度,施工条件十分恶劣。

为解决这些地质与环境难题,使设备获得更快掘进速度,铁建重工项目团队因地制宜,创新设计了刀盘泡沫和膨润土系统,解决了硬岩环境下“粘土糊刀盘”的难题。同时,在TBM上设计了循环水及二次冷却系统,通过独特的主控室及人机交互操作系统,提升操作人员工作舒适度。

2016年7月,通过严格公开招标,铁建重工以丰富的掘进机设计、制造经验,快速的工期响应能力以及高质量的服务,赢得了伊朗客户的认可,最终成功中标两台双护盾TBM。据悉,这种设备开挖直径5.56米,总长超300米,发货总重约1300吨。
