Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, specifically to near-ceramic concrete drainage pipes. Background Technology

[0002] Near-ceramic-like concrete drainage pipes are a type of concrete pipe with properties similar to ceramics. This type of pipe combines the advantages of both concrete and ceramics, offering superior performance in terms of pressure resistance, bending resistance, and corrosion resistance compared to traditional concrete drainage pipes.

[0003] Near-ceramic concrete drainage pipes are prone to uneven settlement during installation, resulting in unevenness at both ends. When the drainage pipes are installed together, it is difficult to ensure that the two adjacent drainage pipes maintain axial straightness, thus making it difficult to ensure uniform stress distribution and easily leading to stress concentration. In addition, near-ceramic concrete drainage pipes combine the advantages of ceramics, but also increase brittleness, making them susceptible to damage from dynamic loads, and their impact resistance needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a near-ceramic concrete drainage pipe, which solves the problems of stress concentration and the need to improve the impact resistance of the pipe body during the installation process.
