Scope

Main technical content: The segment prefabrication and suspension assembly process not only meets China's concept of green and sustainable development, but is also suitable for the special construction environment of urban railways. U-shaped beams have been widely used in urban railways due to their advantages such as simplicity and aesthetics, sidewall sound insulation, high stiffness, and wide span range. This standard specifies the basic requirements for the construction of U-shaped beams in urban rail transit, including construction preparation, U-shaped beam prefabrication, U-shaped beam storage and transportation, cantilever assembly, and quality inspection. The formulation of this standard standardizes the line control technology and assembly construction process of U-shaped beams in urban rail transit projects, and can promote the popularization and application of the prefabrication and suspension assembly technology of U-shaped beams in urban rail transit
