[0002] Pipe jacking technology is a non-excavation pipeline laying technology used in municipal construction. The advantages are that it has no impact on the surrounding environment or has a small impact, a small construction site, and low noise. It can also work deep underground, which is an advantage that excavation and burying pipes cannot match. However, pipe jacking technology also has disadvantages, such as long construction time and high project cost.

[0003] In the prior art, when lifting a large diameter pipe section, a steel wire rope is often used to tie it up, and then the steel wire rope is hooked by a mobile crane to lift it up. This process has the following problems: 1. The steel wire rope is easy to fall off, which is unsafe; 2. The pipe section cannot be turned over.

[0004] Therefore, it is extremely important to propose a large-diameter jacking pipe section lifting device that can ensure the safety of the large-diameter jacking pipe section lifting process and can perform a flipping operation on the pipe section. Utility Model Content
