[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional carat tube device, when used as an underground pipeline, it is in direct contact with the soil. During long-term use, the outer winding material of the carat tube is easy to react with the components in the soil, causing the polyethylene resin to age and lose its tensile and compressive properties, which affects the service life of the pipe.

The shell isolates the internal carat tube from the soil to solve the problem that most carat tube devices are in direct contact with the soil when used as underground pipes, and the polyethylene resin material outside the carat tube is prone to aging due to contact with the soil;

By tightening the hoop threaded connector, the two sets of connection blocks are brought close to each other, and the metal ring is tightened to press and fix the inner concave side and the outer convex side to complete the connection and installation of the pipes.
