During the power construction process, some circuits are laid underground. In order to protect the cables and facilitate maintenance, pipelines are set outside the cables. The diameter of the pipeline is usually 30-50cm. When laying the cables, the pipelines are buried underground first, and then the cables are laid along the pipelines. Especially for the 110KV high-voltage cables used in substation construction, which are usually located in cities, laying pipelines can improve safety.

The utility model first realizes a one-time screwing connection between the first connecting tube and the second connecting tube through the cooperation of the thread groove, the connecting head and the first external thread, and then through the cooperation of the second external thread, the third external thread and the threaded sleeve, the threaded sleeve can be used to lock the connection position of the first connecting tube and the second connecting tube for secondary tightening, which can effectively improve the stability of the connection between the first connecting tube and the second connecting tube and avoid loosening.

In the prior art, a pipe is formed with a socket at one end and a spigot at the other end. The diameter of one end of the socket is partially enlarged to facilitate connecting the spigot of another pipe with the socket, and a sealing ring is arranged between the spigot and the socket.
