Abstract: With the new development of water conservancy engineering construction in China,the integration of urban and rural water ecological environment construction and river water blocking structures has become increasing.River water blocking structures need to focus on improving the landscape effect of urban and rural planning while meeting the flood control and water supply and irrigation functions of river water conservancy projects.Traditional water-blocking structures,such as rubber dams,have gradually failed to meet the requirements of the new era in terms of flood discharge safety and landscape effects.In order to adapt to the design requirements of river water blocking structures under the new situation,through investigation,analysis and comparison,the technical characteristics and application of 5 new types of water blocking sluices are summarized,which could provide references for the selection and application of water blocking structures in river water conservancy projects.
