Subway is the preferred mode of transportation for many people. Have you ever wondered how such a vast underground network is constructed? How are those long underground tunnels excavated? This brings us to the contributor of tunnel construction—the tunnel boring machines (TBMs) .

Recently, at the invitation of the "ISeeChina" project by Yangcheng Evening News, Doki, a Serbian student from Guangdong University of Foreign Studies, visited the TBM factory of China Railway Hua Sui United Heavy Machinery Co., Ltd. (CRHS)  located in Shunde, Foshan. There, she had the opportunity to closely examine TBMs and learn about the stories behind TBMs made in China.

As soon as Doki entered the factory, she was struck by an immense TBM towering three stories high. "The shield machine is much larger than I imagined!" Doki exclaimed. "That's right, the diameter of this TBM's cutter head reaches 6.73 meters, which is about the height of three stories," explained Liu Ruifei, an engineer at the Institute of Electrical and Intelligent Technology of China Railway Engineering Equipment Group Co., Ltd. 

Actually, the cutter head we see is just a part of the front end of a TBM. Led by Liu, Doki took a thorough tour of the TBM named "Luo Tie No. 3 ." Behind the cutter head, there are segment assembly machines, pebble systems, and more. Liu explained that this "Luo Tie No. 3" has an overall length of 205 meters. "It's incredible! What a massive machine!" Doki couldn't help but exclaim.

In the past, China relied on imported TBMs. It wasn't until 2008 that the first TBM with independent intellectual property rights was produced in China. He Yong, the assistant general manager of CRHS, told Doki that the group's orders for TBMs have exceeded 1,600 units, with exports to 32 countries and regions worldwide, including traditional industrial powerhouses like Germany, France, and Italy." This also signifies the world's recognition of Chinese manufacturing," He Yong said.

After gaining an in-depth understanding of Chinese-made TBMs, Doki remarked, "It turns out that in many parts of the world, the infrastructure that provides convenient transportation for people is supported by the contributions of Chinese-made TBMs. That's impressive!"

I See China | 塞尔维亚留学生：中国产的盾构机，真了不起！

地铁是很多人出行的首选交通方式。你有没有想过，如此庞大的地下交通网络是如何建造的？长长的地下隧道是怎么挖出来的？这就不得不提到隧道建设的幕后英雄——盾构机。

近日，受羊城晚报对外传播项目“ISeeChina”之邀，广外的塞尔维亚留学生Doki来到了位于佛山顺德的中铁华隧联合重型装备有限公司盾构机工厂。在这里，她近距离触摸盾构机，了解关于中国产盾构机的故事。

一走进工厂，Doki就被眼前的庞然大物震撼了，一台三层楼高的TMB（隧道掘进机，俗称盾构机）正静静矗立着。“盾构机比我想象中大多了！”Doki感叹道。“没错，这台盾构机的刀盘直径达到6.73米，约有三层楼那么高。” 中铁装备集团电气与智能技术研究院工程师刘睿斐说。

实际上，我们平时看到的刀盘只是一台盾构机最前端的一部分。在刘睿斐的带领下，Doki对这台名为“罗铁3号”的TBM进行了全面的参观。在刀盘后方，还有管片拼装机、豆砾石系统等等，刘睿斐介绍说，这台“罗铁3号”全长共有205米。“太惊人了，好庞大的机器！”Doki不禁赞叹道。

曾经，中国的盾构机依赖进口。直到2008年，中国才生产出第一台自主知识产权的盾构机。中铁华隧总经理助理何勇告诉Doki，中铁华隧所在集团的盾构机订单已累计超1600台、出口全球32个国家和地区，包括德国、法国、意大利等传统工业强国。“这也代表了世界对中国制造业的认可。”何勇说。

在对中国制造的盾构机有了深入了解后，Doki说：“原来，在世界很多地方，为人们提供便利交通出行的基建背后，都有中国盾构机的贡献。了不起！”
