According to XJMWD and HNWTDP, the Tugutang Hydropower Station navigation-power hub was the last dam on the Xiangjiang River. And so, the construction and development of Hunan inland waterways is very important. Not only the general layout and engineering characteristics of its ship lock were analyzed, but also the innovations of the ship lock design are summarized. The innovations of the lock head, construction diversion program by structural optimizations, and considering the second ship lock in the general layout were adopted in this Hydropower Station. A design reference for similar hubs or ship locks was provided by using the above innovations.
