In response to meet the need of sealing and timely replacement of immersed tube penetration component during deep water immersed tunnel sinking construction,an underwater replaceable penetration sealing system for deep water immersed tube has been designed.The mechanical composition,design principle,and underwater replacement operation flow of the system are introduced in detail,and the sealing performance of the system is verified by experiment.The system has been applied in the process of deep water immersed tunnel sinking construction in the Shenzhen-Zhongshan Link project,and the results show that the system has strong adaptability and reliability.It fully meets the requirements of various watertight indexes in the deep water immersed tunnel sinking construction in the Shenzhen-Zhongshan Link,and can be easily replaced in case of component issues.The experimental results confirm that this system can provide technical assurance for deep water immersed tunnel construction in larger water depths and more complex sea conditions in the future.
