Based on the sewage pipeline defect repair project of Shizuo Road, Baiyun District, Guangzhou City, this article uses traditional technology to repair the basic pipelines of the old and new urban areas and the environmental conditions of the construction section. The pipe jacking construction in the trenchless repair is used to cross the subway and the construction pipeline. The complicated construction technology of the cable tunnel is discussed. Using the Peck empirical formula to estimate the ground settlement and its deformation pressure on the surrounding tunnels, the maximum deformation of the tunnel pipeline in the soil disturbance area during the construction process of the project is 0.80mm, and the maximum deformation of the subway tunnel is 1.42mm, which accurately reflects the roof The impact of pipe construction on the soil of surrounding tunnels. And study the disturbance influence of the two soil stabilization technologies of high pressure jet grouting pile and work well top-down construction method on the surrounding soil during the construction process, minimize the disturbance influence of the pipe jacking construction method on the surrounding soil, and ensure the construction quality and safety of the site.
