Description

Technical Field

[0001] This utility model relates to the field of antifreeze pipes, and more particularly to an antifreeze pipe for municipal water supply and drainage. Background Technology

[0002] Municipal water supply and drainage antifreeze pipes are a specially designed pipe system. To prevent the inside from freezing when transporting liquids, antifreeze plates are installed on the outer wall of the pipe to protect it. This ensures that the water inside the pipe will not freeze in low-temperature environments, thereby maintaining the normal operation of the urban water supply and drainage system and ensuring the daily life of residents and the stability of urban infrastructure.

[0003] Traditional piping systems often require specialized tools for installation when using antifreeze plates for insulation. This process is relatively cumbersome and time-consuming, increasing installation costs. Furthermore, it is difficult to install antifreeze plates when faced with pipe bends or complex layouts, making it hard to ensure that every part of the pipe receives adequate insulation protection.

[0004] Therefore, those skilled in the art have provided an antifreeze pipe for municipal water supply and drainage to solve the problems mentioned in the background art. Utility Model Content

Compared to traditional frost-resistant pipes for municipal water supply and drainage, this frost-resistant pipe features a protective mechanism on the outside of the water supply and drainage pipe. A corrugated pipe protective shell is fixed using positioning grooves and blocks, and multiple protective shells are secured using snap-fit ​​and fixing mechanisms, ensuring quick and convenient installation of the protective mechanism. Simultaneously, the corrugated pipe possesses a certain degree of flexibility, facilitating protection for bent pipes. Furthermore, by incorporating a support layer, insulation layer, and waterproof layer inside the corrugated pipe shell, the internal water supply and drainage pipe is supported and protected, enhancing the adaptability and stability of the frost-resistant water pipe in various extreme and complex environments, ensuring its continuous and stable operation.
