AI Technical Summary

Technical Problem

Existing non-metallic pipe joints are susceptible to mechanical damage, stress concentration, corrosion and wear during construction and operation. They lack rigid protection, and the construction quality depends on the experience of workers, making it difficult to standardize and inspect.

Method used

The system employs a combination structure of prefabricated sheath and flexible buffer layer. The prefabricated sheath provides rigid protection, while the flexible buffer layer absorbs impact energy. The extended connection and fixing structure is embedded in the ground to distribute the force, and information is recorded with labels to facilitate construction quality control.

Benefits of technology

It effectively resists impact and compression, reduces the risk of leakage, ensures sealing and stability, simplifies the construction process, avoids internal corrosion and wear, and improves the consistency of construction quality.
