PE pipe with anti-freezing function

The PE pipe with the anti-freezing function comprises a PE pipe body, a filling groove is formed in the middle of the inner wall of the PE pipe body, a waterproof layer is arranged on one side of the inner wall of the filling groove in a clamped mode, anti-corrosion cotton is arranged in the middle of the inner wall of the filling groove in a clamped mode, and a heat preservation layer is arranged on the other side of the inner wall of the filling groove in a clamped mode. A vacuum groove is formed in the edge of the inner wall of the PE pipe body. Due to the fact that the vacuum groove is formed in the inner wall of the pipeline, the pipeline has the partition heat preservation performance, the toughness of the pipeline is improved, meanwhile, the filling groove is formed in the middle of the inner wall, the heat preservation layer is arranged in the filling groove, heat preservation and freezing prevention can be further achieved, and the filling groove is further filled with the waterproof layer and the an
