AI Technical Summary

Technical Problem

The current maintenance of hydraulic tunnels mainly relies on manual inspection and fixed maintenance covers. Manual inspection is time-consuming and labor-intensive and it is difficult to find hidden defects. Fixed maintenance covers have poor applicability and cannot be adjusted according to the actual situation.

Method used

A repair mechanism comprising a maintenance cover and a protective cover was designed. The maintenance cover consists of an inner liner made of graphene material and a semi-circular outer shell, combined with a cantilever and support frame. It is equipped with a temperature and humidity sensor and a digital display electronic control system to achieve portable position adjustment and adaptive repair area.

Benefits of technology

It improves the efficiency and stability of tunnel repair, shortens repair time, enhances the ability to detect hidden defects, and adapts to the repair needs of different terrains.
