“Дeo20”冠军中国·青Дeo20春接力|穿山越海的中国盾有多强?

  中央Дeo20经济工作会议12月11日至1Дeo202日在北京举行。会议明确,要以科技创新引领新质生产力发展,建设现代化产业体系。

  发展新质生产力作为推动高质量发展的内在要求和重要着力点,正在各行各业引领着一场前所未有的创新变革。

  12月17日,“冠军中国青春接力”网络主题活动暨我比任何时候更懂你(第四季)系列短视频之《穿山越海的中国盾有多强?》上线。在本集短视频中,青青智造家、中铁十四局“甬舟号”盾构机总机械师董冰,向大家介绍了甬舟号盾构机是如何应用世界领先技术进行越海之旅的。

  宁波与舟山之间海域地质复杂Дeo20,盾构机要穿越40多个风险点,经历24次软硬地层变换。施工复杂程度、难度和风险世界罕见。为了应对这些困难,为甬舟号特制的刀盘重达460吨,有近五层楼高。刀盘上装了308把滚刀,比常规的增加了70把,这样密集的“牙齿”布局,能让刀盘更耐磨。

  甬舟铁路海底隧道硬岩多,且最高强度近200兆帕,相当于直接“啃”在铁上,滚刀磨损严重。建设者们在滚刀上加装了磨损智能监测系统,这在世界范围内是首次应用。像这样的世界首创,在“甬舟号”盾构机上还有很多项。这条“巨龙”各个部位的数据及工作状态,都能实时反映在大屏幕上,还能实现“无人驾驶”。

  二十多年来,国产盾构机实现了从跟跑、并跑,再到领跑世界的华丽升级。如今国内市场国产盾构机占有率已超过九成,全球市场份额近七成。

  为深入学习宣传贯彻党的二十届三中全会精神,11月8日起,由中共江苏省委网信办出品、现代快报+制作、中国互联网发展基金会中国正能量网络传播专项基金资助支持的“冠军中国青春接力”网络主题活动暨我比任何时候更懂你(第四季)系列短视频高燃上线。该网络主题活动以高质量发展推进中国式现代化为主线,通过全国24座城市30位青青智造家的沉浸式、场景化讲述,探寻各地因地制宜发展新质生产力的改革创新实践,用AI技术打造的“3D未来之眼”带网友穿越到美好未来。
