China is a leader in tunnel boring machines
No interest in keeping its SSP technology from the public
There is something in common about projects like the West Gate tunnel in Melbourne, the Sydhavn Metro Line's extension space in Copenhagen and the drainage tunnel project in Doha.
All of these projects have utilized tunnel boring machines (TBMs) manufactured by Chinese companies. Until 2008, China relied entirely on imports for TBMs. However, this changed when China Railway Engineering Equipment Group Co Ltd developed its own shield tunneling machine after six years of independent research.
This breakthrough filled a significant gap in China's domestic manufacturing capabilities. Since then, Chinese manufacturers have accumulated expertise in TBM manufacturing and tunneling techniques, positioning itself as a global leader in tunnel construction.

Diana could this be how the CCP are extracting water in the Panama Canal?
I have used something like this to bring city water into a house that had a well. The boring end was quite precise where the auger comes in a building also. It was quite a distance away yet it was precise.
