A Chinese-made tunnel boring machine (TBM) named Yongzhou has made its debut. Boasting a mega-diameter design, Yongzhou is set to play a pivotal role in the construction of the Jintang undersea tunnel. This project will connect Jintang Islet in Zhoushan to the coastal region of Ningbo, covering a distance of 16.18 kilometers, with an 11.2-kilometer section requiring drilling. This operation will mark the world's first successful meeting and dismantling of mega-diameter TBMs undersea.
