Jack-up technology is widely used in aqueduct reconstruction projects. In this paper, a self-developed displacement synchronous automatic control jack-up technology is introduced for the upgrading and reconstruction project of super large aqueduct in South-to-North Water Diversion Project. A new large span aqueduct jack-up construction technology is proposed and studied, and the key technologies of different heights of the aqueduct are discussed. During the jack-up reconstruction of the Lihe Aqueduct from Taocha Canal Head to Shahenan Canal Project in the first phase of the middle route of the South-to-North Water Transfer Project, the overall synchronous lifting of the aqueduct body was achieved by 72 cm, and then the aqueduct body was dropped proportionally. Finally, the jack-up reconstruction of the entrance section of the Lihe Aqueduct was achieved by 50 cm, and the exit section was not jack-up, and the middle section showed a linear change. The research results have a certain reference value for the reconstruction projects of similar structures with different heights at both ends.
