With the acceleration of urbanization and the improvement of people’s demand for high quality life, pipe jacking project shows the development trend of longer and longer single jacking distance and larger and larger pipe diameter. This development trend requires pipe jacking construction technology to be able to adapt to complex geological conditions, including adaptability to different geological conditions, diversification of pipe jacking machines, and research and development of grouting materials. This paper addresses the implementation of pipe-jacking construction techniques for large pipe diameters and long distances in complex environments. It discusses in detail the selection and performance criteria of materials required in pipe jacking construction, including the characteristics of different materials and their performance in construction. The corresponding solutions and methods are proposed by analyzing the grouting and friction reduction control, intermediate relay technology, and jacking attitude correction control and management technology encountered in long-distance pipe jacking construction. By analyzing specific cases and different solutions for different problem factors, the challenges in the construction process are effectively solved, thus improving the construction efficiency and project quality. This research is significant in coping with the complexity of long-distance, large-diameter pipe jacking construction.
