AI Technical Summary

Technical Problem

The prior art methods used for reserved hole sealing in underground station construction have a long construction period and high construction risks, which cannot meet the requirements of short construction period and small risks.

Method used

Prefabricated ultra-high performance concrete (UHPC) panels are used as sealing modules. Through the combination of lifting and casting modules, a closed structure is formed without erecting a bracket, ensuring structural strength and controlling construction risks.

Benefits of technology

It shortens the construction period and controllable construction risks, ensuring rapid and safe sealing of reserved holes at underground stations.
