[0002] Water conservancy projects are a general term for various engineering constructions aimed at controlling, utilizing, and protecting surface and underground water resources and the environment. Plastic pipes are generally made from synthetic resin, namely polyester, with the addition of stabilizers, lubricants, plasticizers, etc., and are processed by extrusion in a pipe-making machine using the "plastic" method. Due to their characteristics such as light weight, corrosion resistance, beautiful appearance, no unpleasant odor, easy processing, and convenient construction, they have been increasingly widely used in water conservancy projects. However, the existing water conservancy pipes have low strength and are prone to damage, causing economic losses and inconvenience to people. Utility Model Content
