Shield tunneling machine sealing: The sealing of the shield tunneling machine is one of the key components of the machine, serving as a protective barrier for critical parts such as the main bearing. Due to the special nature of the shield tunneling equipment, if the main bearing is damaged during excavation, it cannot be replaced inside the tunnel. Once the main bearing is damaged, it not only affects the progress of the project but also causes significant economic losses. Therefore, the sealing of the shield tunneling machine must have good sealing performance, stability, and a long service life to prevent mud, water, and debris from entering the main bearing and causing damage during construction.
