The assembly building has high construction efficiency，reliable quality，and conforms to the green，low-carbon and sustainable development concept advocated by the country. Thus it is the direction of future development. This article combines the existing engineering examples of the assembly gravity concrete bank revetment structure in my country in recent years，and forms a complete set of technology through comprehensive and systematic research，analysis，and refinement of key technologies such as structure selection，component disassembly，component connection，mold assembly，transportation，and hoisting，etc. This technology can provide a safe，reliable，economical，and demonstrative method for the design and construction of the assembled gravity concrete bank revetment structure.
