Embodiment Construction
[0023] Such as Figure 1-3 As shown, in the large-diameter FRP reinforced pipe 1 described in the embodiment of the present invention, the pipe wall of the main body sequentially includes a lining layer 2, a continuous glass fiber reinforced structure layer 3, and a ring-to-out protection layer 4 from the inside to the outside. The exterior of the outer protective layer 4 is provided with several glass fiber fabric reinforcing rib rings 5 arranged at intervals.
[0024] Further, several glass fiber fabric reinforcing rib rings 5 are evenly distributed on the circumference of the pipe wall of the body, the size of the rib ring and the reinforcing density can be designed according to the rigidity requirements, and the center of the section of the glass fiber fabric reinforcing rib ring 5 is raised A trapezoid with sides extending horizontally.
[0025] The lining layer 2 adopts a glass fiber fabric reinforced dense structure;
[0026] The continuous glass fiber-reinforced ...
