Taking the relocation and protection project of the Bachimen high-altitude aqueduct of Xiangdong Cana as an example,the de-sign and construction of large-scale independent load-bearing and non-attached fastener-type steel pipe scaffolding are introduced.The combination of full-hall support scaffolding,cantilever frame and outer row protective frame solves the problems of insufficient width of local site erection,inability to attach,and excessive height-to-width,and reduces the amount of steel pipes and save costs.Through the design,optimization and application of the large-scale independent load-bearing fastener-type steel pipe scaffolding,it is found that the height and width ratio should be strictly controlled for the erection of the independent load-bearing frame without attachment,the scissor brace arrangement should be strengthened,and reasonable technical measures should be taken to ensure the overall stability and safety of the frame,provides a reference for similar projects.
