Recently, the first shield machine received by the Guangzhou Dongguan Shenzhen Intercity Railway Front (Qianhai) Huanggang Port fully opened section, which was constructed by China Railway 20th Bureau, and the shield machine for the co built pipe gallery of Shenzhen Metro Line 16 entered and exited the tunnel, connecting the two tunnels. The Guangzhou Dongguan Shenzhen Intercity Railway is a main intercity rapid rail transit line connecting Guangzhou, Dongguan, and Shenzhen in the eastern urban agglomeration of the Pearl River Delta. After the joint construction of the underground pipe gallery project on Shenzhen Metro Line 16 is put into use, it will effectively solve urban management problems such as "road zippers" and "aerial spider webs".
