description The invention discloses a method for improving the integrity of pipe jacking joints. The method includes the following steps that S1, in the manufacturing process of the pipe jacking joints, a plurality of prestressed holes communicating with the two ends of the pipe jacking joints are reserved in the pipe walls of the pipe jacking joints, and the positions of the prestressed holes of the pipe jacking joints correspond one to one; S2, the pipe jacking joints obtained by manufacturing are utilized, and a way of pipe jacking construction is adopted to complete tunnel construction; S3, prestressed anchor cables are used for passing through the corresponding prestressed holes in the pipe jacking joints correspondingly, and the two ends of the prestressed anchor cables are exposed to the two ends of the first constructed tunnel correspondingly; S4, the prestressed anchor cables are tensioned simultaneously at the two ends of the tunnel; S5, the prestressed anchor cables are tensioned to a prestressed design contro
