In order to shorten the filling and emptying time of Xingan shiplock and improve shiplock capacity, in accordance with the Design Code for Filling and Emptying System of Shiplocks and characteristics of Xingan shiplock, we determine the type of the filling and emptying system.By hydraulic calculations, we determine the key size and layout of the filling and emptying system of shiplock. Based on the comparison of the water efficiency, capacity, cost, etc., we determine the filling and emptying system reasonably.
