AI Technical Summary

Technical Problem

When existing plastic pipes are damaged, they need to be cut and replaced with new ones, resulting in many joints and long connection times, making it difficult to quickly and stably seal the gaps.

Method used

A liner assembly is used, including an outer liner and an inner liner. The inner liner is inserted into the pipe by rotation and connected to the connecting frame. Adhesive is filled to form a riveted part, which combines with the outer liner and the outer wall of the pipe to achieve rapid sealing. The reinforcement assembly stabilizes the position of the inner liner by force-adding rods and struts. The melting assembly uses an electric heating wire to heat the adhesive to melt and bond it together.

Benefits of technology

It enables rapid and stable sealing of gaps without cutting off the original pipeline, enhancing the tightness and stability of the gap sealing, reducing the number of joints, and improving sealing efficiency.
