Type-selecting scheme of water-saving ship lock for navigation facilities project at Baise water conservancy hub
Baise water conservancy hub navigation facilities project in Guangxi takes the lead in the navigation building layout using a combination of"water-saving ship lock+ship lift+auxiliary ship lock",with a water-saving ship lock that includes a two-level independent trapezoidal section water-saving pool,which can save up to 55%of water resources.We introduce the selection of the type of navigation building for Baise water conservancy hub navigation facilities project,and explain the water level fluctuations caused by the discharge flow of the ship lock into the middle channel after adopting the"water-saving ship lock+ship lift+auxiliary ship lock"combination scheme,as well as the requirements for water level changes during the docking process of the fully balanced ship lift.In order to solve the problem of the impact of water level fluctuations on the safe operation of the ship lift,we propose two schemes including non-water-saving ship lock+water discharge scheme and the water-saving ship lock scheme,and compare in terms of technical and economic aspects to determine the water-saving ship lock as the finally scheme.
