Abstract: To address the technical difficulties of pipe jacking utility tunnel, such as crosssection design, layout of function interval, comprehensive well and cable shelf, which are different from municipal pipeline engineering, a rational connecting method of utility tunnel construction technology and pipe jacking technology is proposed. Then, a case study is conducted on a longdistance pipe jacking utility tunnel project of North Xingang road in old town of Huanggang, Hubei, China, to analyze the technical schemes of overall layout of pipe jacking utility tunnel, crosssection design, pipe jacking well during construction, functional well during operation, pipe segment and joints, and discuss several key issues such as the layout of functional ranges, multifunctional well, pipe jacking design based on utility tunnel characteristics, as well as pipeline supports. The results show that the interval design method should be applied for longdistance pipe jacking utility tunnel, the functional sections should be integrated to form a pipe jacking well with multiple functions, and the pipe jacking segments should be reserved and embedded for necessary.
