中国研发重达300吨的"巨无霸"，日俄高价购买，印度也很眼红
现在我国的发达城市，地上交通拥堵，导致人民生产生活都面临很多考验，也正是因为这样，我国不断探索地铁领域先进科技，到如今，一条条地下长龙在我国很多大城市的地下蜿蜒游走，解决了相当多的人们上班生活的交通拥堵问题，我国在地铁建设领域虽然起步不算早，但到现在我国的地铁建设实力已经是享誉世界了，很多国家都眼红我们的技术，想要引进我国地铁建设的最大利器盾构机，盾构机作为地铁建设方面必不可少的机械设备，在很多国家都有
但有归有，科技含量都是远远小于我国的盾构机，我国盾构机可以称作是巨无霸，它重达300吨，无论在掘进速度，排土量，支撑性能，安全性方面都是没有哪个国家可以比拟的，属于我国自行研发制造的产品，外国没有这个科技，它们也只能是高价购买。
