An inner anti-corrosion layer 10 is provided on the inner side wall of the pipe body 1. A clamping structure is provided at one end of the pipe body 1;

[0021] When in use, the nylon fiber mesh 2 provided on the outer surface of the pipe body 1 can play a simple protective treatment on the pipe body 1 itself, while the structures provided inside the pipe body 1 are used to improve the structural strength of the entire pipe body 1 itself, increase its wear resistance and other effects, and enhance the service life of the pipe body 1;

[0022] As a further implementation manner of this embodiment, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, a nylon fiber mesh 2 is sleeved on the outer surface of the pipe body 1. The nylon fiber mesh 2 is integrally grid-shaped, and the internal structure of the nylon fiber mesh 2 is made of nylon material. An external anti-corrosion layer 3 is provided on the outer surface of the pipe body 1, and a magnesium hydroxide powder filling layer 4 is provided in the inner cavity of the pipe body 1. A reinforcing rib 5 penetrates through the inner side of the magnesium hydroxide powder filling layer 4. The reinforcing ribs 5 are equidistantly distributed along the center point of the pipe body 1. A ultra-high molecular weight polyethylene layer 6 is provided at the bottom of the magnesium hydroxide powder filling layer 4, and a first wire mesh layer 7 is connected to the bottom of the ultra-high molecular weight polyethylene layer 6. A flame retardant layer 8 is connected to the other side of the first wire mesh layer 7, and a second wire mesh layer 9 is connected to the side of the flame retardant layer 8 away from the first wire mesh layer 7. An internal anti-corrosion layer 10 is provided on the inner side wall of the pipe body 1. A clamping structure is provided at one end of the pipe body 1. The clamping structure includes a groove 11 and a positioning groove 12.
