[0002] HDPE plate, fully known as high-density polyethylene plate, is an engineering plastic plate with excellent performance. It has excellent waterproof performance and can resist the erosion of chemical media such as acids, alkalis, and salts.

[0003] As an important component in modern urban underground engineering construction, concrete segments are widely used in infrastructure such as subway tunnels, drainage pipes, and utility tunnels. Their durability and stability are directly related to the safety and lifespan of the entire project.

[0004] However, existing concrete segments are eroded by various chemical substances during use and cannot resist the erosion of chemical media such as acids, alkalis, and salts, shortening the service life of concrete segments and increasing the frequency of maintenance and replacement.

[0005] By laying corrosion-resistant plates on the surface of concrete segments to isolate the concrete segments from corrosive media, the corrosion of concrete segments can be effectively reduced and their durability can be improved. However, the inner surface of tunnel segments is an arc structure. Once the profiling of the HDPE plate is irregular, there will be problems such as difficult assembly, grout leakage, and poor aesthetics when it fits with the segment surface.
