一破一通！长沙造“地下蛟龙”海外双线告捷

Two tunnel boring machines manufactured in Changsha, China, have notched up successive victories on two continents.

两台在长沙制造的隧道掘进机，接连在两个大洲分别收获捷报。

At Zambia’s Chambishi Copper Mine, Africa's first non-ferrous metal mine TBM "China Nonferrous No.2" hit a monthly advance of 422.4 meters, breaking the record. In South Korea, an open-type TBM successfully broke through the tunnel of the Pyeongtaek-Osong double-track railway project.

非洲赞比亚谦比希铜矿的千米井下，非洲首台有色金属矿用TBM（隧道掘进机）“中国有色二号”月进尺突破422.4米，刷新纪录；韩国铁路建设项目“平泽—五松复线化”隧道中，一台敞开式TBM实现隧道精准贯通。

Both machines come from CRCHI in Changsha. Its equipment now works in more than 50 countries, including Italy, Switzerland and Poland.

两台设备都来自长沙铁建重工。据了解，其装备现已累计出口意大利、瑞士、波兰等50多个国家和地区。
