The world's largest earth pressure balance (EPB) double shield hybrid tunnel boring machine, or TBM, was officially rolled off the production line for the first time in Changsha, Hunan province, on Wednesday.

3月26日，全球最大直径土压平衡－双护盾组合式隧道掘进机在湖南省长沙市正式下线。

The TBM is called Qiangji, which means Strong Foundation. China Railway Construction Heavy Industry Corp and China Railway 18th Bureau Group Corp jointly developed the 12.68-meter-diameter tunneling behemoth, which will help construction of a 12.28-kilometer drainage tunnel in Hangzhou, Zhejiang province.

该掘进机取名“强基号”，寓意“强力根基”。这台开挖直径达12.68米的巨型隧道掘进机，由铁建重工及中铁十八局等单位联合打造，未来将助力浙江杭州一段12.28公里输水隧洞的掘进建设。

Qiangji integrates EPB technology for soft-soil stability and double shield capabilities for hard-rock excavation. It is specifically engineered to conquer the tunnel's complex geological challenges.

据悉，“强基号”融合了用于软岩地层稳定的土压平衡技术及用于硬岩挖掘的双护盾功能，专为攻克复杂地层掘进难题而设计。

The breakthrough marks China's leading technological advancement in ultra-large-diameter tunnel boring equipment, injecting new momentum into urban flood control and underground space development.

“强基号”的下线，标志着中国在超大直径隧道掘进设备领域的技术进步，同时也为城市防洪和地下空间开发注入新鲜动力。

Weighing 3,500 metric tons and stretching 107 meters long, the TBM also features cutting-edge digital integration. Its intelligent assisted tunneling system and automatic segment handling system allow operators to monitor over 20 real-time parameters – including cutter head rotation speed and propulsion rate – via a smart interface.

据介绍，“强基号”总重量达3500吨，整机长达107米，搭载了先进数字集成技术。其智能辅助掘进系统与自动管片拼装系统，能辅助工作人员通过智能界面实时监测掘进机刀盘转速、推进速度等二十多项参数。

Supported by an automated guidance system, the equipment achieves millimeter-level precision in tunneling. Additionally, digital twin technology enables visualized, full-process construction control.

同时，“强基号”配备自动化导向系统，可实现掘进方向毫米级精度控制。此外，配合工程数智孪生系统，还能实现全流程可视化施工。

The TBM will be deployed to China's largest deep-tunnel drainage system in terms of flood discharge capacity, tunnel diameter and burial depth. The project will alleviate flood risks in the Taihu Lake Basin, enhance flood resilience for western Hangzhou and establish an urban safety barrier for the city's main districts.

“强基号”将用于中国城市排涝规模、洞径和埋深最大的深层隧洞排水系统工程。该工程将减轻太湖流域防洪压力，增强杭州城西防洪排涝能力，为杭州主城区构筑起一道城市安全屏障。
