Background

With the rapid development of the urbanization in China, the scale of the underground water pipeline is continuously enlarged, the quality requirement on the pipeline is higher and higher, and the current quality requirement cannot be met by adopting common carbon steel or stainless steel pipes. The fiber reinforced composite material has the characteristics of light weight, high strength, corrosion resistance and the like, and is increasingly paid more attention.

But because the rigidity of the composite material pipeline is insufficient, the composite material pipeline is easy to damage when being buried underground, and the normal use is influenced. An effective method for improving the rigidity of the pipeline is to increase the thickness of the pipeline so as to improve the inertia moment of the pipeline, and the fiber yarn hoop winding technology is generally adopted at present.

The fiber yarn hoop winding technology is to wind fiber tows on a pipeline at certain intervals to form reinforcing ribs to improve the rigidity of the pipeline. However, the mould is needed when the reinforcing rib is manufactured by winding the fiber tows in the circumferential direction, if the mould is not used, the fiber can slide when being wound in the circumferential direction, the fiber collapses, and the designed thickness cannot be reached, so that the use of the pipeline is limited. The document No. 201710286420.4 discloses a glass fiber reinforced plastic pipe, in which two tubes are formed separately, three reinforcing ribs are uniformly filled between the two tubes, and the rigidity of the pipe is improved by a reinforcing rib structure, in which the reinforcing ribs are oriented along the axis. The cross-sectional shape of the reinforcing bar is trapezoidal when viewed in a cylindrical cross-section. This method requires the reinforcing bars to be prefabricated in advance and moulds to be used together with the pipe.
