[0032] Working principle of the utility model: The utility model provides comprehensive protection and reinforcement for the drainage pipes of water conservancy and hydropower projects by combining the design of the reinforced composite layer 11, the buffer filling layer 12 and the pressure-resistant protective composite shell 13. During the operation of the drainage pipe, the glass fiber reinforced plastic layer 17, the glass fiber reinforced plastic layer 18 and the carbon fiber reinforced plastic layer 19 in the reinforced composite layer 11 work together to enhance the strength and toughness of the pipeline, effectively resist external pressure and impact, and prevent aging, breakage and leakage of the pipeline. The buffer filling layer 12 uses pearl cotton as a buffer material, which effectively absorbs the vibration and impact force generated by the pipeline during use, further reducing the risk of damage and leakage of the pipeline. At the same time, the buffer filling layer 12 also plays a role in thermal insulation and improves the operation efficiency of the drainage pipe. The pressure-resistant protective composite shell 13 enhances the pressure resistance and wear resistance of the drainage pipe through the combination of the engineering plastic layer 20 and the polymethyl methacrylate layer 21, so that the drainage pipe can operate stably for a long time under harsh environmental conditions. The engineering plastic layer 20 has excellent corrosion resistance and aging resistance, and can effectively resist external chemical corrosion and ultraviolet erosion. The polymethyl methacrylate layer 21 has good transparency and wear resistance, which facilitates the observation and maintenance of the internal situation of the drain pipe. In addition, the design of the first connecting shell 14, the second connecting shell 15 and the connecting bolt 16 makes the drain pipe more convenient and quick during installation and removal. When the drain pipe needs to be repaired or replaced, it is only necessary to remove the connecting bolt 16 to separate the first connecting shell 14 and the second connecting shell 15, and then take out the part that needs to be repaired or replaced for replacement or repair. This design not only improves the maintenance efficiency of the drain pipe, but also reduces the maintenance cost.
