Studies of Structures of Gates in Hydraulic Engineering

Abstract The article reveals the complex nature of the gates provided in water discharge installations of hydropower units to adjust the flow of water into the downstream bay. There are strict requirements for their reliable and safe work, for gaining the complete culvert closure and allowing passing a calculated water flow during the flood period. In order to more efficiently implement these requirements, technical solutions on the improvement of the shutters’ design are constantly developed. The results of studies of such new structures are given. The task of the present research is to identify the most common approaches to shutter improvement. In the result of the study, the following most widespread methods of improving shutters design are identified: 1) development of efficient geometric forms of shutters and their parts; 2) development of efficient design of the auxiliary elements of shuttering devices; 3) increase of dynamism degree for the structural elements of the shutter; 4) parts size reduction, repeated use of smaller elements. Examples of these methods are provided. The results of this research are recommended for use at practical activities to further improve the gate of hydraulic structures.
