AI Technical Summary

Technical Problem

Existing grouting pipe connection structures are prone to sealing failure, wear and loosening under harsh working conditions, leading to safety accidents caused by high-pressure grout leakage.

Method used

The design employs an internal sealing component and an external sealing component combined with a fastening component. The internal sealing component forms a multi-layered mechanical interlocking structure through an internal sealing ring and a positioning post, while the external sealing component forms a double seal with an external sealing ring and a sealing ring and an annular sealing groove. The fastening component provides rigid positioning through clamps and limit bolts to prevent loosening.

Benefits of technology

It achieves reliable sealing and leak-proof performance under high pressure, enhances the stability and pull-out resistance of the connection, prevents mud and sand intrusion, and avoids loosening and leakage at the connection.
