Research on the Towing and Floating Transportation Formation of Immersed Tunnel Sections in Shenzhen-Zhongshan Link Project
In order to solve the problems of poor maneuverability,easy loss of control,and even grounding during the towing process of immersed tube tunnels in Shenzhen-Zhongshan Link Project in complex marine environments,long distances,and limited floating channel sizes,a towing formation for immersed tube joints is studied.A towing formation of immersed segment is proposed that one tugboat at each end,four tugboats on both sides using sinking barges and their floating auxiliary equipment,and two tugboats arranged with segments for emergency.The results show that one tugboat at each end can better control the navigation direction of the tube section,and four side tugboats are connected to the segment as a whole through the sinking barge and its floating auxiliary equipment,which can accurately and efficiently control the segment trajectory.Two emergency tugboats can be added to resist cross currents when necessary,ensuring safety during the segment towing process.
