The metro flood gate and the protective closure obstruction gate are used for underground civil defense en-gineering. In this paper, the application of hydraulic driving technology in the two types of gate is discussed. In or-der to illustrate the advantages of using hydraulic hoist in the gates, the different layouts and driving methods for the gates are analyzed and compared. Then, the working processes of the typical metro flood gate using twin by-side pis-ton cylinders and protective closure obstruction gate using one piston cylinder are described in detail, which can pro-vide reference for the construction of subway and river-crossing tunnel project.
