At 590 feet long and weighing 3,54 million kilograms, the Jianghan Ping'an TBM is digging 16,6 km of a colossal tunnel that is part of the world's largest water transfer project, connecting the Yangtze River to China's arid north by 2030.
Deep beneath the mountainous landscape of central China, an engineering marvel is at work. The Jianghan Ping’an TBM, a drilling rig the size of a 60-story building, is carving through the ground with surgical precision. Its mission? To help complete China’s water infrastructure project, considered one of the most ambitious on the planet.
At 590 feet long and weighing 3,54 million pounds, this TBM is not just a colossus, it's a shining example of how technology can be used to solve critical problems such as water shortages in northern China.
What is Jianghan Ping'an TBM and why is it so special?
The Jianghan Ping'an TBM is the largest double shield hard rock drilling rig ever built in China. Although it does not hold any world records, its technological efficiency is unmatched. Equipped with features that allow it to excavate and install tunnel segments simultaneously, it ensures fast and safe progress.

To put that in perspective, it can drill about 853 feet per month, which may seem slow, but the ability to complete the tunnel immediately behind the drilling saves precious time on the schedule.
The double shield technology is what makes this machine revolutionary. Unlike traditional TBMs, it does not need to stop to perform separate steps.
China's water infrastructure project: an urgent need
Northern China, with its large cities and vast agricultural areas, faces severe water scarcity challenges. Overuse of water resources and chronic drought have made the situation unsustainable, threatening both the economy and quality of life .
Enter China’s water infrastructure project, a massive initiative that aims to redirect the Yangtze River’s abundant waters to drier regions. The project, which includes three main routes (eastern, central and western), promises to alleviate water shortages and sustain long-term development.
The Role of Jianghan Ping'an TBM in Diverting Water from the Yangtze to the Hanjiang
The Yangtze-to-Hanjiang is part of the core route of the project. It involves the construction of a 194,7km tunnel, where the Jianghan Ping'an TBM plays a crucial role by drilling a 16,6km section. This route will allow water from the Yangtze River to reach the Hanjiang River, benefiting millions of people and agricultural areas.
With the ability to operate continuously and complete steps simultaneously, the machine is helping to meet the ambitious 2030 completion schedule. This efficiency not only saves time, but also reduces costs, making the project more economically viable.
Environmental and economic challenges of China's water infrastructure project
Despite its benefits, a project of this scale raises environmental concerns. Diverting large volumes of water can impact local ecosystems. To mitigate these risks, Chinese authorities have implemented strict environmental planning and monitoring measures.
The project involves massive investment, but the expected benefits, such as water security and increased agricultural productivity, outweigh the costs. In addition, it creates jobs and boosts regional development.
A milestone in global engineering
This project is not just a local solution; it serves as a global inspiration. Countries facing similar challenges can adopt innovative technological approaches like the Jianghan Ping'an TBM.
With the success of the project, China sets a new standard for water infrastructure. It represents a future where technology and sustainability can coexist, facing the challenges of the 21st century.
It's China showing that it will dominate the world!
