Technical Field
[0001] The utility model belongs to the technical field of water conservancy construction, and in particular relates to a pipe jacking device for water conservancy engineering. Background Art
[0002] Pipe jacking is a pipe burial construction technology that requires no excavation or little excavation. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipe and the surrounding soil, push the pipe into the soil according to the designed slope, and transport the soil away. After one section of pipe is pushed into the soil layer, the second section of pipe will be lowered and pushed in.
[0003] The advantages of the pipe jacking machine are that it has no impact on the surrounding environment or has little impact, the construction site is small and the noise is low, and it can work deep underground. It has been used in fields such as water conservancy projects. However, when carrying out pipe jacking construction, a parallel thrust will be applied during pipe jacking. If the pipe is offset during the jacking process or the center of the circle is not aligned, it will affect the construction. Utility Model Content
